EXECUTIVE SUMMARY
In the process of modifying Special Committee Formula, in order to cover
certain gang activities left out which affect track maintenance effort and to
take into account the effect of machine packing and track modernisation, the
Committee on Manpower and Cost Norms for Track Maintenance (MCNTM)
found it more logical and rational to adopt zero based approach.
0.2
The Activities of track maintenance are categorised as follows:
PRIMARY MAINTENANCE ACTIVITIES : These are directly related to P.Way
maintenance, needing manpower based on continuous length of track, further
classified as follows:
•
Activities T (Affected by Traffic density):
These are aimed at achieving
safety and acceptable running quality, commensurate with the loads and
speeds carried.
•
Activities R (Routine: Unaffected by traffic density):
These
are
for
maintaining track, formation and other integrated assets, which are of
routine nature, but quite important for train operation and for achieving
reliability and long life of assets.
AUXILIARY MAINTENANCE ACTIVITIES : These are related to upkeep of
P.Way section as a whole, needing manpower based on localised problems,
special features and geographical nature of P.Way section, further classified
as follows:
•
Activities M (Miscellaneous): For these activities, the quantum of work
arising in the P.Way section can be assessed on a universally adoptable
basis and the yardstick relating mandays requirement to output is
rationally stipulated for each subactivity.
•
Activities S (Site-specific):
For these activities, the quantum of work
arising varies from location to location depending on site-specific features
of the P.Way section and the yardstick is stipulated generally based on
past experience.
[Para 3.3]
1
(Vol.1)
0.3
The methods of track maintenance and the manpower requirement thereof
are entirely different between non-suburban line and very busy suburban line.
The Committee defines a suburban line as ‘High Density Suburban Line’, if
both the following criteria are fulfilled:
•
Train frequency should exceed 8 per hour.
•
Night blocks are invariably essential for maintenance of track.
The Chief Engineer (PHOD) will be competent to classify a suburban section
as ‘High Density Suburban Line’ based on the above criteria.
[Para 5.2, 5.5]
0.4
Field data indicate that under machine packing the difference in performance
between PRC and other types of sleepers is not very significant. Moreover all
machine packed sections are mostly laid with PRC sleepers.
Therefore
Committee decided not to have different norms for PRC and other types of
sleepers. Likewise packing need for SWR or LWR track is not much different
from that for non-welded track, which is contrary to theoretical expectations.
This situation exists because large number of welds have developed defects
and the sleepers at these locations require packing often. SEJs in LWR track
require frequent attention. Apart from rewelding of failed rail-welds, repair
welding works have to be carried out often, even before weld failures/cracks
take place, in the interest of safety. Destressing of LWR panels is an extra
activity. Due to these reasons manpower requirement for Activities T and R is
the same, irrespective of the track having SWR/LWR or not, under the present
conditions. Realising the problems arising due to rail welds of poor quality
and deficiency in the design of SEJ, steps have been undertaken to improve
the quality of welds and SEJs through technologically superior inputs. In this
context, it is relevant to refer Para 15 of Summary of Recommendations in
Part I
of ‘Report of the Railway Safety Review Committee, 1998’.
The
MCNTM Committee recommends that the effort to improve rail welds should
receive adequate thrust and that a review should be made after 5 years from
now, so as to evolve reduction factors to be applied for the yardstick of
manpower requirement for SWR/LWR track. Till this is done, the Committee
2
(Vol.1)
decided that the subactivities under Activities T and R will be separately
identified for only three types of track, irrespective of the type of sleepers and
irrespective of rails being fish plated or welded as SWR/LWR:
0.5
•
Machine packed track (non-suburban)
•
Manually packed track (non-suburban)
•
Machine packed track (high density suburban)
[Para 3.2]
The subactivities under Activities T and R were identified after interaction with
field engineers and deliberations. These are listed for machine packed and
manually packed (non-suburban) tracks and machine packed (high density
suburban) track, as follows:

0.6
The Committee decided that all the subactivities of maintenance for Running
Yard Lines (RYL) and Non-running Yard Lines (NRYL) should be categorised
under Activity R, since the proportion of traffic passing through these lines out
of the gross traffic on the section is not only negligible, but also varies widely
in different locations, apart from being associated with slow speed. Therefore
regular cycle of maintenance, not related to the quantum of traffic on mainline,
will be adequate for RYL and NRYL.
[Para 4.7.1, 4.8]
0.7
The ‘Rational Formulae’ have been evolved by the MCNTM Committee by
collecting field data over 14 non-suburban sections and 3 high density
suburban sections through direct interaction with field engineers on seven
zonal railways and after carrying out critical analysis of the data and also
review of the rationale underlying Special Committee Formula in the light of
the fresh data. Rational Formulae for Activities T and R are given as follows,
along with necessary explanations:

Note:
•
RYL : Lines on which trains are received on signal
•
NRYL : Non running lines in yard, marshalling lines, sidings, etc.
•
The maintenance of RYL and NRYL is entirely regarded as Activity R and
mandays requirement is computed as per the above table. Activities T, M
and S are not involved at all.
•
1 km of manually packed NRYL is equivalent to 2/3 km of manually packed
RYL, as regards mandays requirement.
•
Mandays tabulated above shall not be enhanced by the factors A, B and C,
which are applicable only for mainline track and not for RYL or NYRL.
0.7.7
STAFF STRENGTH FOR MOBILE MAINTENANCE UNIT (MMU)
0.7.7.1 Gross Equivalent MMU mandays, i.e, GEMM over a subdivision/division
A.
For Non-suburban machine packed mainline (BG):
= Σ LM (40+1.15GMT) (1+A+B+C) + 35 Σ LM + 35 Σ L Y
where
[Para 4.11.1 to 4.11.8]
LM = length (in km) of typical stretch of machine packed main line (BG)
LY = length (in km) of typical stretch of machine packed yard running line (BG)
5
(Vol.1)
B.
For High Density Suburban machine packed mainline (BG):
= ΣLH(75+1.5GMT)(1+A+B+C) + 120ΣL H
where
[Para 5.7.1 to 5.7.3]
LH = Length (in km) of typical stretch of high density suburban mainline
Both for A and B above, the Chief Engineer can vary the value of GEMM and cadre
structure of MMU, depending on the local conditions, job requirement and efficiency
of MMU.
0.7.7.2 Principle governing the strength and composition of MMU
80% of annual emoluments of GEMM = Annualised cost of SEMMU + Annual
emoluments of MMU staff.
[Para 4.11.9, 5.7.4]
SEMMU is the Speciality Equipment of MMU, namely, on-track/off-track tampers and
vehicles (road, rail-cum-road, rail-borne) for transport of men and materials.
The cadre structure of Gangmen and pay scales thereof, as stipulated by the Railway
Board should be taken into account and Leave Reserve of 12.5% should be allowed,
while computing the annual emoluments of GEMM. The cadre structure and pay
scales should be taken into account and Travelling Allowance payable should be
allowed, while computing the annual emoluments of MMU.
0.7.8
ENHANCEMENT FACTORS A, B AND C
a)
Formation Factor A: This factor brings into consideration the nature of soil
in formation/cutting and has the following values:
Nature of soil
Shrinkable soil and vicious Black Cotton soil (very bad soil)
Ordinary unstable soil (bad soil)
Stable soil
Value
0.2
0.1
0
The Formation Factor should be applied only for the length of track having
very bad/bad soil conditions in formation/cutting.
[Para 4.6.1]
b)
Alignment Factor B: This factor brings into consideration the curvature of
track and has the following values:
B = 0.25 for curves sharper than 2o, decreasing from 0.25 to 0
linearly for the variation 2 o to 1 o, and thereafter 0 for curves flatter
than 1o.
MG: B = 0.25 for curves sharper than 4o, decreasing from 0.25 to 0
linearly for the variation 4 o to 2 o, and thereafter 0 for curves flatter
than 2o.
NG: B = 0.25 for curves sharper than 7o, decreasing from 0.25 to 0 linearly
for the variation 7 o to 3 o, and thereafter 0 for curves flatter than 3o.
BG:
The Alignment Factor should be applied only for the length of track having
[Para 4.6.2]
curves as detailed above.
6
(Vol.1)
c)
Rainfall Factor C: This factor brings into consideration the annual rainfall
and has the following values:
C = 0.2 for annual rainfall of 300cm and above, decreases from 0.2 to 0
linearly for the variation 300cm to 150cm and thereafter 0 for rainfall less than
150cm.
[Para 4.6.3]
0.7.9
EQUIVALENT LENGTHS FOR TURNOUTS AND SPECIAL LAYOUTS
a)
The turnouts and special layouts should be treated as equivalent lengths of
straight track as follows:
Turnout
Diamond
Diamond crossing with single slip
Diamond crossing with double slip
Cross over
Three-throw points and crossing
Scissors cross-over
Trap
Double trap
0.10 km
0.10 km
0.15 km
0.20 km
0.20 km
0.20 km
0.50 km
0.02 km
0.04 km
b)
If a layout connects the Main Line (ML) to ML/RYL/NRYL, its equivalent track
length is added to the length of ML for the purpose of computing mandays
requirement. If the layout connects RYL to RYL/NRYL, its equivalent length
is added to RYL length. If the layout connects NRYL to NRYL, its equivalent
length is added to NRYL length. In other words, the equivalent track length is
added to the more important line connected to the turnout or special layout.
c)
The equivalent track length of layout computed as per para (a) will be
considered in addition to the physical length of the layout which is treated as
part of ML/RYL/NRYL, for computation of mandays requirement.
In
otherwords, the length of the layout is not to be deducted from the length of
parent track.
d)
The length of track in RYL and NRYL will be measured from the heel of the
crossing and not from the toe of switch. Similarly, in diamond crossings with
single or double slips, the curved lead of the slip/slips will not be included in
the length of track.
e)
In accordance with the mode of packing of the layout, its equivalent length of
track should be treated as machine packed or manually packed, for the
purpose of computing mandays requirement.
f)
Equivalent track lengths of turnouts and connections are considered only for
Activities T and R. The track length parameters wherever used for computing
mandays requirement for Activities M and S should exclude such equivalent
track lengths.
[Para 4.9]

(Vol.1)
0.8
The Rational Formulae have been evolved systematically based on the
quantum and norms for the subactivities of track maintenance, which are
transparent in Tables P, P1/P2, P3, Q1/Q2, R1/R2, S, S1, T and U.
The
Committee recommends and has already incorporated in the Rational
Formulae, that shoulder screening of ballast need be done at 5 years interval.
This activity should be mechanised on priority all over Indian Railways. As
the modernisation in various subactivities progresses, some of the
subactivities may reduce in quantum or may vanish; or these may require less
manpower. Thus Rational Formulae can be amended easily, by recasting the
relevant Tables. The Committee recommends that the Rational Formulae can
be reviewed once in five years and amended.
0.9
[Para 9.8 & 9.9]
Based on the Rational Formulae, the Committee has concluded that by
deploying on-track tampers for machine packing on BG, it is possible to
achieve savings in maintenance cost and manpower, compared to
maintenance by manual packing to the extent (approximately) as follows:
Traffic density
30GMT line
20GMT line
10GMT line
3.333GMT line
Savings in Annual
maintenance cost/km

* The initial and running cost of speciality equipment for MMUs, in the form of annualised
cost, has been taken into account while computing the savings in annual maintenance cost.
@
The staff strength of MMU, namely artizans and helpers has been taken into account while
computing the savings in manpower.
The Committee recommends that maintenance by Mobile Mechanised Units
(MMUs) should be expanded at a fast pace so as to achieve economy and to
impart job enrichment to gangwork.
In view of the substantial savings achievable through the single aspect of
mechanisation, namely, machine packing, as illustrated above, the Committee
recommends that tie-tamping machines should be introduced on a large scale
on MG system also, constituting 19,158 km of track, irrespective of the type of
sleepers used, since it is the reality that MG track will continue to exist on a
number of routes for years to come.

and S&T departments.
Note:
a)
Clearing of vegetation not in the vicinity of tracks will be carried out by the
respective departments or by the works supervisor concerned, through contract.
b)
Cleaning of goods sheds and goods platform will be the responsibility of Commercial
department, who may resort to contracting.

The mandays requirement computed through the Rational Formulae exclude
provision of 12½% Leave Reserve for gangmen and also posts of,
gangmates, keymen, gatekeepers, artizans, artizan-helpers, trollymen,
storemen, staff of USFD team and on-track machine staff for maintenance
and operation.
However MMU staff strength is carved out of the
gangstrength, as per the principles explained in Recommendation 0.7.7.
[Para 4.10.1]
0.14
The Rational Formulae cover all the activities. When these are implemented,
many of the decasualised posts are likely to be absorbed as regular gangmen
posts. The balance decasualised posts should be declared as surplus and
the incumbents of these posts should be redeployed as per extant rules.
[Para 8.1]
0.15
Issues such as appointment of Safaiwalas in certain gangs, deployment of
gangmen for monsoon patrol and security patrol are covered under the
Rational Formulae.
[Paras 8.2, 8.3, 8.4]
0.16
The Committee have evolved the Rational Formulae based on average
productivity of individual gangman.
It is necessary to ensure overall
productivity by weeding out weak personnel.
As done in army, ‘Physical
Endurance Test’ (PET) should be standardised for gangmen, as criterion for
being qualified at the time of recruitment and also for assessing their stamina
during service. Any gangman declared unfit through PET during periodical
medical examination should be treated as medically decategorised and the
extant rules should be followed, duly removing him from the cadre. If the
performance of a gangman is found to be poor attributable to his physique as
reported by the supervisor, he should be sent for PET, irrespective of whether
he is due for PME or not. This recommendation reflects the views of field
engineers who expressed their anguish regarding the diminishing stamina of
gangstaff.
[Para 8.5.1 to 8.5.5]
12
(Vol.1)
0.17
Innovative methods should be implemented to improve the general health of
gangstaff. Every gangman should be made to realise that it is his duty to
maintain his stamina. As a part of training courses and also in the field, Yoga
should be taught to gangmen.
0.18
[Para 8.5.6]
The Committee recommends that the existing LR percentage of 12½ need not
be altered for gangmen cadre. Absenteeism should be curbed through stern
and expeditious action under DAR.
Divisional Railway Managers.
This is basically the responsibility of
Establishment rules should be amended to
incorporate some of the suggestions made by Hon’ble Justice Shri N.
Venkatachelliah in the course of a judicial enquiry into a railway accident, for
implementing stringent action on habitual absentees. The money saved due
to LWP availed by gangmen or due to absence of gangmen should be
diverted for clearance of maintenance arrears through contract. Compilation
of savings should be done on monthly basis.
Chief Engineers should be
delegated with powers for reappropriation from PU-01 to PU-32 to this extent.
But the Finance Member of the Committee does not concur this
recommendation, pointing out that this will encourage absenteeism.
The
Technical Members are of the opinion that, whereas every effort should be
taken to curb absenteeism, maintenance activities should not be allowed to
suffer due to shortage of input of mandays, in the interest of safety and
realisation of full life span of track.
0.19
[Para 8.6]
Appointment of gangwomen should be restricted to identified posts only.
[Para 8.7]
0.20
The Rational Formulae are based on the manpower requirement for track of
average age.
Any P.Way section will have a mix of new and old tracks.
Therefore, while keeping the overall gangstrength of P.Way section as
calculated, readjustment among the strengths of various gangs may be
carried out as per the age profile of track, with the approval of DEN.
[Para 8.8, 10.6]
0.21
Training centres should be strengthened, so as to impart better skill to
gangmen, including for operating small track machines. The Committee
13
(Vol.1)
recommends provision of Trainee Reserve of 2% for the cadre of gangman.
However the Finance Member does not concur creation of 2% Trainee
Reserve posts and opines that this must be managed within the Leave
Reserve provision. The Technical Members are of the opinion that Leave
Reserve is meant for its own purpose and that with the emphasis being given
to impart adequate training to staff belonging to safety categories, (Para 5 of
Summary of Recommendations in Part I of ‘Report of the Railway Safety
Review Committee, 1998’), this issue deserves Board’s consideration.
[Para 8.9]
0.22
The pilot study conducted by the Committee by theoretically applying the
Rational Formulae on Allahabad, Ambala and Ratlam Divisions for nonsuburban lines and on Mumbai CST and Mumbai Central subdivisions for high
density suburban lines indicates that it would be possible to effectively
pinpoint redundancy or shortfall in gangstrength in various units. The pilot
study has given the confidence that the implementation of Rational Formulae
will only result in savings in manpower and expenditure, at the same time
ensuring equitable distribution of manpower in accordance with workload.
[Para 9.5 to 9.7]
0.23
If accepted by the Railway Board, this Report should be included in the
syllabus of all training courses (initial and refresher) for officers and
supervisors.
All officers and supervisors should become conscious of
manpower utilisation, thereby generating overall cost consciousness.
Application software MANPOWER has been developed by the Committee,
which has been already utilised successfully in the Pilot Study. All engineers
should become conversant with this user friendly software.
[Para 10.1 to 10.4]
0.24
If accepted by the Railway Board, the implementation of the Rational
Formulae should be carried out as per a predetermined time frame, as
elaborated in Chapter 10. Annual review of gangstrength should be carried
out as on 1st April, by continuously updating the input data and by utilising the
software MANPOWER.
Gangstrength should be adjusted accordingly.
14
(Vol.1)
IRICEN should be the custodian of the software MANPOWER, making
amendments arising from time to time and incorporating the review of
Rational Formulae to be carried out at five years interval as recommended in
para 0.8.
0.25
[Para 10.5 to 10.10]
It has been proved that ‘Equated Track Kilometre (ETKM)’ has become an
unreliable Performance Unit, both for manpower and track maintenance cost.
ETKM derives its relevance from Special Committee Formula.
With the
Rational Formulae replacing the Special Committee Formula, the Committee
has proposed ‘Equated Manpower Kilometre (EMKM)’ as the Performance
Unit. For defining EMKM, a comparator P.Way section has been assumed,
which requires 12/3 men per km (as average) of mainline track in the section,
to perform all the Activities T, R, M & S as per the Rational formulae.
Therefore EMKM of any other P.Way section is defined as numerically equal
to 0.6 times the number of gangmen required for the section for all the
Activities T, R, M & S as per the Rational formulae. The ratio of EMKM to
actual length (in km) of each P.Way section will indicate relative manpower
concentration required among various sections. 12/3 times the sum of EMKMs
of all P.Way sections in a unit will bring out the excess/shortfall of manpower,
when compared with the total existing gangstrength in the unit. These have
been elaborated in Chapter 7.
The Committee recommend that EMKM
should be accepted as Performance Unit simultaneously with the adoption of
the Rational Formulae and that, in future, ‘Equated Cost Kilometre (ECKM)’
can be evolved based on the Rational Formulae, as Performance Unit for
track maintenance cost.
0.26
[Para 7.1 to 7.9]
A similar report, namely “Part 2: Cost-Norms” has to be compiled based on
the Rational Formulae. This will enable evolving of procedures to rationalise
track maintenance cost and to judiciously distribute the available funds among
zonal railways and among lower units. This will also create cost awareness in
the minds of field engineers and executives at higher levels. Railway Board
may nominate new members for MCNTM Committee for carrying out this
assignment.

1.1.3 Though the Committee met three times in 1996, held discussions on the
information collected till then and compiled a draft report on the methodology
to modify the Special Committee Formula, further work could not be
progressed for want of Railway Board'
s acceptance/comments on the Report
of the Committee for Machine and Manpower Deployment
for Track
Maintenance (CMMDTM), which was submitted to Railway Board in
Feb.1995.
In the Report of CMMDTM, certain modifications to Special
Committee Formula had been suggested, which had to be interconnected to
16
(Vol.1)
the present Report. When further work was thus kept stalled, both Shri
S.S. Kapoor and Shri S.D. Sharma retired in Jul.97.
1.1.4 Thereafter Railway Board vide letters No.95/CE-I/GNS/2 dt.13.10.97 and
12.11.97 (Annexures B and C) reconstituted the Committee with the following
officers:
•
•
•
•
•
Shri S. Gopalakrishnan, CAO/Construction, NE.Rly: Convenor Member
Shri M.S. Ekbote, Chief Engineer, SE.Rly
: Member
Shri S.M. Singla, Chief Engineer, N.Rly
: Member
Shri Vinod Kumar, Director, IRICEN
: Member
Shri Aurobindo Gosh, FA&CAO, E.Rly
: Member
Railway Board maintained the continuity of the Members by name, rather than
by designation. Shri S. Gopalakrishnan took over as Addl. General Manager,
S.Rly in Dec.97 and Shri M.S. Ekbote as Chief Engineer, W.Rly in May 98.
1.1.5 Based on the comments given by the various Directorates of Railway Board
on the Report of CMMDTM, Member Engineering decided that the
Committee'
s study should follow a zero based approach, instead of proposing
amendments or changes to the Special Committee Formula, so that all the
activities of track maintenance are rationally covered. He also decided that
costing of track maintenance should also be integrated, so that financial
budgeting and manpower budgeting can be compatible to each other.
Towards achieving this objective, the Committee was renamed as '
Committee
on Manpower and Cost Norms for Track Maintenance' (CMCNTM) vide
Railway Board'
s letter No.95/CE-I/GNS/2 dt.13.08.98. (Annexure D)
1.2 TERMS OF REFERENCE ASSIGNED TO THE COMMITTEE
1.2.1 Subsequent to pinpointing initial terms of reference in their letter dated
05.01.96 (Annexure A), Railway Board decided that the Federations of
recognised Trade Unions (namely, All India Railwaymen'
s Federation and
National Federation of Indian Railwaymen) may give Memoranda to the
Committee and also hold discussions with the Committee, vide letter
17
(Vol.1)
No.95/CE-I/GNS/2 dt.13.05.96 (Annexure E). The intention of the Railway
Board was also communicated to AIRF and NFIR.
1.2.2 Railway Board desired,
vide
letter
No.95/CE-I/GNS/2
dt.31.01.97
(Annexure F), that the Committee should examine the question of
appointment of Safaiwalas as part of gang strength for cleaning railway track
passing through densely populated area, since in the case of a passenger
train derailment CRS/Lucknow had observed that track maintenance suffered
on account of the filth on track discouraging gangmen from working efficiently.
1.2.3 Railway Board desired, vide letter No.96/CE-II/PRA/43/CRS dt.04.07.97
(Annexure G), that the Committee should study the aspect of deputing
permanent gangmen to perform monsoon patrolling and allied works (which
are not assigned to them as per Special Committee Formula) and the problem
of making good the mandays lost on this account.
1.2.4 Railway
Board
desired,
vide
letter
No.94/CE-I/EDCE(G)/Misc.7/Track
dt.08.06.98 (Annexure H), that the comprehensive formula for costing track
maintenance given in the Report of the Committee for Rationalisation of
Costing Permanentway Activities (CRCPA) should be considered by this
Committee, so that there is no deviation in the recommendation.
1.2.5 Railway Board desired,
vide
letter
No.96/CE-I/GNS/2
dt.24.07.98
(Annexure I), that the Committee should examine the aspect of creating posts
of additional Permanentway men for carrying out security patrolling, since
CRS/Mumbai recommended that security patrolling should be carried out by
permanent gangmen after investigating into a derailment on Central Railway.
1.2.6 In RDSO'
s letter No.CT/IRPWM dt.27.11.98 (Annexure J), it is stated that in
the Chief Engineers Conference held in Nov.98, it was decided that the age of
gangmen needs to be considered in the gangstrength determination assigned
to the Committee.
Though there is no Board'
s orders to this effect, the
Committee found this point relevant in the context of ensuring productivity. In
fact the Committee is of the opinion that possession of adequate physical
18
(Vol.1)
strength should be the requirement to perform as gangman, rather than age
being the criterion.
1.2.7 In Director/IRICEN'
s letter No.151/9754 dt.27.08.98 (Annexure K), Board'
s
order on the minutes of the CTE'
s Seminar held in Jul.97 was communicated,
according to which the Committee was required to identify the works of track
maintenance which may be executed through contract. A list of such possible
works has been also enclosed to this letter. On the same subject, Railway
Board have issued letters No.86/W6/TK/12 dt.
08.88 and No.97 E/MPP/1/9
dt.13.10.97, addressed to the zonal railways (Annexures L and M) which are
relevant to the Committee'
s terms of reference.
1.3
METHODOLOGY ADOPTED BY THE COMMITTEE
1.3.1 AIRF and NFIR responded to Railway Board'
s desire to give Memoranda to
the Committee, expressing their views on modifying gangstrength formula.
The Committee received a Memorandum from NFIR vide No.DC-76/89
dt.16.06.96 (Annexure M) and Memorandum from AIRF vide No.AIRF/52 (i)
dt.17.07.96 and dt. 01.08.96 (Annexure N).
These were given due
consideration by the Committee.
1.3.2 The Committee requested the Zonal Railways in Feb.96 to communicate their
experience with modern track structure and modern methods of maintenance
and also to furnish details of any work study carried out by them.
Only
Central, South Eastern, Northern and Western Railways responded to this
request.
The contents of their reports received in Jun. to Aug.96 were
considered by the Committee. The views of Zonal Railways as well as AIRF
and NFIR were aimed at modifying the factors and norms built in the Special
Committee Formula. In as much as the reconstituted Committee resorted to
analysis of field data on zero based approach as desired by the Board vide
para 1.1.5, the suggestions for modifying the existing formula got
accommodated in a more rational and direct manner. The Zonal Railways
and the federations had brought to the attention of the Committee many
factors affecting the quality of work and the morale of Permanent way men,
19
(Vol.1)
which have been considered by the Committee while formulating the
recommendations.
1.3.3 The Committee also noted the contents of the Report of Manpower
Productivity Committee 1986 (which was not however accepted by the
Railway Board) and RITES Diagnostic Study on Manpower Planning on
Indian Railways (May 1990).
1.3.4 The Committee also studied two reports finalised by separate Committees:
•
Report of the Committee for Machine and Manpower Deployment for
Track Maintenance on Indian Railways, submitted in Feb.1995, by the
Committee comprising of Adviser (Civil Engineering)/Railway Board, Chief
Engineers of some Zonal Railways, Director Standards (Track)/RDSO and
Director/IRICEN. This Report was not accepted by the Railway Board,
after discussion among various Directorates including Finance. Extracts of
the notings recorded in Board'
s office were made available to the
Committee through Board'
s letter No.95/CE-I/GNS/2 dt.17.02.98.
The
reconstituted Committee found these documents to be very useful and a
fresh zero based strategy was formulated in the first meeting of the
reconstituted Committee held on 20.03.98 at Pune.
•
Report of the Committee for Rationalisation of Costing Permanent Way
Activities, submitted in Dec 1995, by the Committee comprising of CTEs of
some
Zonal
Railways,
Director
Standards
(Track)/RDSO
and
Director/IRICEN. This Report has been neither accepted nor rejected by
the Railway Board. But their letter dt.08.06.98 (Annexure H) indicates that
the concepts contained in CRCPA Report are relevant to be considered by
the Committee.
1.3.5 The Committee visited seven Zonal Railway headquarters, viz. Central,
Northern, Southern, Western, South Eastern, Eastern and South Central
20
(Vol.1)
Railways to collect field data of track maintenance on non-suburban and
suburban lines. There were direct interactions with Section Engineers, Senior
Section Engineers, Assistant Engineers and Divisional Engineers. They had
been asked to come with actual data on manpower utilisation, as per their
own documents. The field engineers were allowed free discussion with the
Committee
and
the information/data/norms/views/problems/solutions
placed by them were recorded.
as
Thereafter, the data were condensed in
formats and analysed.
1.3.6 Some of the points raised by NFIR and AIRF (Annexures N and O) were
discussed with field engineers and their views were noted.
1.3.7 The Convenor Member was asked to participate in the Conference of Senior
Divisional Engineers of all the divisions on Indian Railways specially
organised by the Railway Board on 31.10.98 at New Delhi, to discuss on the
various subjects connected with the maintenance of concrete sleeper track.
The interaction on such a wide base was useful in the thought-process
leading to the compilation of this Report.
1.3.8 The Committee also visited Konkan Railway on 12.05.99 to study the track
maintenance system adopted by KRCL and held discussion with their
engineers. This was useful in judging how far KRCL model can be adopted
on Indian Railways.
1.3.9 The Convenor Member and Chief Engineer/N.Rly accompanied the Members
of Railway Board, when they inspected the Mechanised Maintenance Unit
(MMU) based at Aligarh, Northern Railway on 14.02.2000.
This visit was
useful in appreciating the functioning of MMU under the real field conditions.
1.3.10 While examining the data on workload and manpower utilisation, as collected
from 14 non-suburban and 3 suburban sections on seven zonal railways vide
para 1.3.5, the Committee found that in some of the busily worked suburban
sections, the availability of working period in day time is meagre and, even
during night, all maintenance operations have to be crash programmed within
21
(Vol.1)
4 to 6 hours.
The pattern of manpower deployment in these suburban
sections has to be different from that in non-suburban mainlines.
The
Committee therefore had exclusive interactions with the track engineers of
suburban sections of Central and Western Railways and this has lead to
evolving of exclusive manpower formula for '
high density suburban section'
,
which is defined by the Committee in the Report.
1.3.11 The Committee has also evolved revised man-power formula for manually
packed track of BG, MG and NG to replace the existing Special Committee
Formula, which had not covered many indispensable activities of track
maintenance.
1.3.12 The Committee realised that it is impossible to suggest a single formula (like
Special Committee Formula) if all the direct and indirect activities of track
maintenance have to be covered. The recommendations lead to stipulation of
a set of formulae, which have been named by the Committee as ‘Rational
Formulae’. For any given section, only the relevant formulae out of this set
have to be applied. The Committee have also identified the activities which
have to be performed through contracts. The manpower management issues
raised in paras 1.2.2, 1.2.3, 1.2.5, 1.2.6 and 1.2.7 have been either tackled
within the formulae evolved, or covered under recommendations.
1.3.13 Since the calculation of manpower requirement as per the Rational Formulae
calls for collection and storage of large amount of field data and application in
a number of formulae, the Committee realised that a computer program has to
be necessarily evolved.
Accordingly software MANPOWER on Microsoft
EXCEL has been prepared. Since the proposed formulae are zero based,
distinctly different from the existing formula in use, the Committee was curious
to assess the effect of implementing the same, as to whether it will result in
creation of extra posts or in surrender, with respect to exiting sanctioned
strength. Therefore a pilot study was conducted on Allahabad, Ambala and
Ratlam Divisions (non-suburban sections) and on the Mumbai suburban
sections of Central and Western Railways. This study was very helpful in
22
(Vol.1)
debugging the software and in assuring that the implementation of the new
formulae on global basis on Indian Railways will result in savings only.
1.3.14 The Committee decided that IRICEN/Pune will be the custodian of the
software MANPOWER in future. This will be a useful and indispensable tool
for the periodical review of gangstaff strength. Since this software has been
evolved in a centralised manner, instead of permitting Zonal Railways to
evolve different versions in their own ways, the software will permit
transmission and compilation of data through networking among Subdivisions, Divisions, Zonal Railways and Railway Board.
1.4 MEETINGS HELD BY THE COMMITTEE MEMBERS

SUGGESTED METHOD TO ACCEPT THIS REPORT ON MANPOWER-NORMS
Since zero based methodology has been adopted by the Committee as
required by the Board, it would be appropriate that the Report is first
scrutinised and accepted by the Railway Board, before holding discussions
with NFIR and AIRF. This is because, the initial views communicated by the
Federations (Annexures N and O) pertain to ‘modifying the existing Special
Committee Formula’, the concept that was changed subsequently.
The
Committee Members may be asked to be present when the Railway Board
holds discussions with the federations.
1.6
COMPILING OF THE REPORT ON COST-NORMS IN FUTURE
Referring the contents of para 1.1.5 and 1.2.4, this Report namely ‘Part-1:
Manpower-Norms’ has to be followed by “Part-2: Cost-Norms’ to stipulate the
procedure for recording the track maintenance expenditure on a day-to-day
basis at the field level and to compile and monitor the expenditure at higher
levels. Based on this, systems have to be so developed that money is spent
judiciously as per the importance and condition of track in various routes.
Only by this process, it will be possible to create cost consciousness and to
equitably distribute the funds among zonal railways, among divisions and
among lower units. Today the expenditure per km depends more on the style
of spending money by the individual units. The Report of the Committee for
Rationalisation of Costing Permanent Way Activities (Dec.95) is aimed at
rationalising track maintenance cost.
But this Report is based on Special
Committee’s Gang Strength Formula. As soon as the Rational Formulae for
manpower is accepted, work has to start to revise the Report of CRCPA. It is
recommended that the Railway Board many nominate new members for
MCNTM Committee and assign the task of compiling ‘Part 2: Cost-Norms’.

(Vol.1)
1.7
The observations made by the Finance Member on this Report and the
remarks thereof given by the Technical Members have been incorporated in
Chapter 11, which require Railway Board’s consideration.
1.8
The Committee places on record their sincere thanks to Shri S.S. Kapoor,
Retd.CE, SE.Rly and Shri S.D. Sharma, Retd.CE, N.Rly for their ground work
in framing this Report. Valuable suggestions made by the Chief Engineers,
other officers and officials of Zonal Railways and also by NFIR and AIRF are
thankfully acknowledged.
Special mention deserves to be made of the
excellent work done by Shri Prashant Kumar, CTE/TM and Shri Parmeshwar
Funkwal, Dy.CE (TMC) of Western Railway and their team of computer
personnel in developing the software MANPOWER.
Thanks are expressed
to Shri C.G. Jagannathan, Sr.Clerk, General Manager’s Secretariat, Southern
Railway who prepared this Report on computer.
The Report is placed for Railway Board'
s acceptance.

BACKGROUND LEADING TO THE PRESENT STUDY
Before the amalgamation of company railways and state railways into the
Indian Railways, the yardstick for gangstrength was varying among various
units.
The Maflin'
s Formula adopted in 1931 had brought about some
uniformity. In 1959, the Lobo Committee appointed by Railway Board arrived
at '
Modified Maflin'
s Formula'and the same was adopted vide Board'
s letter
No.60/WI/MTCE/19 of 06.08.62. But before this could be implemented in full,
further implementation was frozen in Jan.'
65. Another Committee to review
the Gangstrength Formula submitted a report in Aug. 1971.
Yet another
Committee submitted a report in Aug. 1972. No decision was taken on the
recommendations contained in both these reports.
2.2
In Jan. 76, Railway Board appointed a Special Committee, with the following
terms of reference:
a)
Report on the requirement of staff for maintenance of track under
various conditions for –
i.
manual maintenance as provided for in the Indian Railways Way
& Works Manual;
ii.
maintenance under the Directed Maintenance system;
iii.
maintenance under the Measured Shovel packing system;
iv.
maintenance by machines;
v.
maintenance of different kinds of sleepers – concrete sleepers,
steel trough sleepers with and without elastic fastenings, CST-9
and wooden sleepers.
b)
The requirement should be separately assessed for BG, MG and NG
and for fish plated track, track with short-welded rails as well as long
welded rails.
This Committee submitted in 1979 "Report of the Special Committee for
Evolving Gang Strength Formula for Uniform Adoption on Indian Railways".
26
(Vol.1)
This Committee held meetings with AIRF & NFIR and incorporated in the
Report their remarks against the suggestions put forth by the Federations.
2.3
The Special Committee'
s Formula and their recommendations along with the
yardstick for gangworks were adopted by the Zonal Railways gradually, even
though Railway Board'
s clear acceptance of the Report is not traceable.
However
vide letters No.E(NG)/II/77/CL/46/E.Rly dated 12.01.83 and
20.01.83, Railway Board ordered that the gangstrength as calculated by
Special Committee'
s Formula be implemented after reducing it by 5%.
2.4
A write-up "Equated Track Kilometre and Gang Strength" is placed at
Appendix 1.
Maflin'
s
This gives in brief the details of Maflin'
s Formula, Modified
Formula,
Special
Committee’s
Formula
and
their
salient
recommendations. A good understanding of the contents of Appendix 1 is
essential to appreciate this Report.
2.5
The concept closely related to gangstrength is '
Equated Track Kilometre'
,
which is the metricated form of ‘Equated Track Mile’, evolved as an integral
component of Modified Maflin'
s Formula. Gangstrength is worked out based
on the prescribed norm – '
Number of men per equated track kilometre'
. The
computation of equated track kilometre, as laid down under Modified Maflin'
s
Formula, remains unaltered till date and Special Committee did not attempt to
amend the same.
2.6
Railway Board vide their letter No.88/CE-I/GNS/1 dt.02.01.1989 constituted a
Committee of Chief Engineers, Director Standards Track/RDSO and
Adviser/Civil Engineering to evolve a new formula for deployment of machine
and manpower for satisfactory maintenance of track for all gauges, i.e. BG,
MG, NG and under varying conditions. In 1995 this Committee submitted the
Report giving recommendations applicable only for double line machine
maintained LWR track on BG. In this Report of the Committee on Machine
and Manpower Deployment for Track Maintenance (CMMDTM) the following
important recommendations were made, as regards gangstrength, in addition
to various other recommendations pertaining to deployment of machines:
27
(Vol.1)
(a)
Continuance of Gangstrength Formula in the same format as Special
Committee Formula.
(b)
Laying down the values of Traffic Density Factor U beyond 1.4 for
traffic density exceeding 20 GMT per annum and also additional
increments to the value of U for plying BOXN rakes and for running
trains at speeds exceeding 110 km/h.
(c)
Reduction of correction factor K (stipulated by the Special Committee)
to 60% of its original value, which will set apart a margin of 40% to
cater for the cost of Mobile Mechanised Unit, to effect some element of
overall savings.
But the Railway Board did not accept this Report. The notings in the files of
Board'
s office indicate their view that there is need for zero based approach
rather than modifying certain factors which were themselves adopted
arbitrarily while framing Modified Maflin'
s Formula and Special Committee
Formula.
2.7
Before the Railway Board could finalise their views on the Report of
CMMDTM, the present Committee was constituted vide Rly. Bd'
s letter
No.95/CE-I/GNS/2
dt.05.01.96
(Annexure
A)
to
modify
the
Special
Committee'
s Formula. The notings in the files of Railway Board indicating
their views on the Report of CMMDTM (1995) were made available to the
present committee in Feb.'
98 and this event only had enabled the Committee
to firm up their views on the methodology to be adopted for collecting field
data and compiling this report.
2.8
With the terms of reference to rationalise expenditure per ETKM of track,
Railway
Board
vide
letter
No.94/CE-1/EDCE(G)/Misc.17
dt.26.08.94
constituted a committee, who submitted their report in Dec.'
95. The Report of
the Committee for Rationalisation of Costing Permanentway Activities
(CRCPA) presumes that the recommendations at (a) and (b) of para 2.6
above, made in the Report of CMMDTM, will be accepted by the Board.
Though the concept of costing contained in the Report of CRCPA is found
28
(Vol.1)
generally acceptable to Railway Board (as inferred from the letter at Annexure
H), the same will require further revision following the zero based approach
for gangstrength determination in the lines as recommended in this Report.
This part of the work has to be accomplished through Part-2 of this Report, to
compile which the Railway Board may nominate fresh members for the
Committee.

OF
TRACK
MAINTENANCE
Before analysing the compulsions of the present situation which call for
rationalising manpower norms for track maintenance, it is necessary to
examine the statistical data pertaining to the variation of trackmen-strength
and track maintenance workload over a decade in the past.
2.9.1 The following tabular statement brings out the trend of change taking place on
Indian Railways with regard to the staff strength as well as the gross workload
of track maintenance in terms of ETKM:

There was an error in the value of ETKM given by N.F.Rly in 19901991 thereby ETKM was being shown more by about 4000 units in all
subsequent years as well. These have been corrected in this tabular
statement.
2.9.2 As could be seen from column (f) of the table under para 2.9.1, ETKM has
increased from 1,30,168 in 1987-88 to 1,43,327 in 1998-99. As obvious from
the definition of ETKM, this increase is consequent to three factors:
•
Increase of loading density on track
•
Increase in length of running line due to new lines and doublings
•
More MG routes converted into BG

(Vol.1)
2.9.3 The following inferences are drawn.
2.9.3.1 By definition, ETKM = LxUx(1+A+B+C), vide details in para 2.1 of Appendix 1.
The Traffic Density factor U increases proportional to GMTKM/km, till it
reaches the value 1.4 for GMTKM/km = 20. For further increase in traffic
density, U remains static at 1.4.
But it is technically true that track
deterioration and corresponding maintenance effort grow in linear proportion
to traffic density and therefore limiting the value of U arbitrarily at 1.4 is not
scientifically correct.
The stipulation of U=1.4 for traffic density of
GMTKM/km=20 and beyond, originated from Modified Maflin’s Formula and in
those days traffic density of more than 20GMTKM/km was not existing on
Indian Railways. Unfortunately the Special Committee (1979) did not update
the definition of U (and ETKM) for GMTKM/km exceeding 20. Presently with
a number of heavily worked sections on Indian Railways, with traffic density in
the order of 25 to 65 GMTKM/km, the ETKMs corresponding to these sections
remain artificially truncated at a much lower value. Inspite of this situation,
ETKM on Indian Railways has increased by 10.1% in the past 11 years. But
in reality, if the lacuna in the definition of ETKM had been rectified, the
percentage of increase will be much more than 10.1%.
2.9.3.2 Reduction in the number of trackmen from 3,02,094 (1987-88) to 2,46,379
(1998-99) over a period of 11 years amounts to a reduction of 18.44% with
respect to the starting figure. This can be regarded as 1.68% reduction per
year in linear mode or as 1.84% reduction in geometric mode,
that is, 302094 x (100% - 1.84%)11 = 2,46,379
2.9.3.3 The analysis in para 2.9.3.2 is somewhat deficient functionally, since the
increasing workload of track maintenance has not been integrated. Number
of trackmen per ETKM is a more appropriate parameter to serve the purpose.
Reduction in this parameter from 2.32 (1987-88) to 1.72 (1998-99) over a
period of 11 years amounts to a reduction of 25.93% with respected to the
starting figure. This can be regarded as 2.36% reduction per year in linear
mode or 2.69% reduction in geometric mode,
that is, 2.32 x (100% - 2.69%)11 = 1.72
31
(Vol.1)
2.9.4 The above stated reduction in manpower despite increased work load has
been possible obviously due to track modernisation, which includes laying of
stronger track structure and machine packing which is the only best method
for concrete sleepers. Mechanisation of track maintenance has progressed
appreciably mainly due to introduction of on-track tie tamping machines
supported by dynamic track stabilisers and ballast regulators.
But these
supporting machines are not available in adequate numbers compatible to the
number of tie-tampers, on Indian Railways, as could be seen from the details
given in the tabular statement under para 2.9.5. This table further indicates
that the population of other machines such as shoulder ballast cleaners, etc is
dismally poor, for the size of Indian Railways.
2.9.5 The track machines require exclusive manpower for operation, supervision
and also for the repair and maintenance of the machines themselves.
Therefore it would be appropriate to get a clear picture of the number of staff
associated with the machines, to make sure that the economy achieved by
machines is not significantly offset by the staff strength for machines. The
relevant details are tabulated as follows:

Information on machine holding has been taken from Railway Board’s
Progress Report of January 2000.
Each supervisory unit consists of 2 field units i.e. 4 machines and 8
employees.
Each Repair & Maintenance unit employs 41 men and handles 4 field
units i.e. 8 TTMs. Each TTM therefore needs 8/4 + 41/8 = 7.125 men
in supervisory and R&M units taken together.
Operating staff are provided as per the norms fixed by Railway Board.
Ballast cleaning machines are not considered in the above analysis,
because the deep screening work is taken up by contract and does not
influence the gang strength.
T-28, TRT and PQRS machines are also not considered, because
renewals of points & crossings or CTR/TSR etc. are being done
through contract and are not a part of the work of maintenance gangs.
Thus it would be seen that only 3065 men constitute the mechanisation
workforce and this number is already included in 2,46,379 trackmen (1998-99).
The percentage of machine staff strength is only 1.24% with respect to
2,46,379 and is 5.50% with respect to 55,715 which is the reduction in number
of trackmen over 11 years.
2.9.6 As on 01.04.1999, the track kilometrage (including mainlines and yard lines) is
85,429 km on BG, 19,158 km on MG and 3,826 km on NG. Out of this only
40,287 km of BG track has come under machine packing till 01.04.2000.
Therefore 45,142 km on BG and entire MG and NG systems, totalling to
68,126 km of track is manually packed. Even in machine packed lengths,
large number of activities are carried out only manually, to quote principally
‘shallow screening’ which is highly labour intensive. Since substantial length
of MG routes will continue to exist for year to come, one may wonder whether
MG tie tamping machines can be introduced on a large scale, but judiciously.
2.9.7 The facts and figures highlighted in para 2.9.3 to 2.9.6 prove that the
Engineering Department is proceeding in the right direction and there is ample
scope
for
optimising
manpower
by
progressively
mechanising
the
maintenance.
2.9.8 However, the engineers feel as though a dead end has been reached and
they are puzzled as to how to meet the manpower requirement for additional
assets being added every year, duly controlling the staff cost optimally. They
33
(Vol.1)
look for precise guidelines for manning norms, which should be flexible by
themselves, to adapt according to the stages of future modernisation.
2.10
WHY THE SPECIAL COMMITTEE FORMULA NEEDS REPLACEMENT
It is necessary to fully appreciate the present situation which has called for the
need to replace Special Committee Formula.
2.10.1 There is a short-coming in the recommendation of the Special Committee,
which was not considered as a shortcoming at the time of compilation of their
Report. The gangstrength worked out by the formula was meant to carry out
12 activities listed in their Report and freedom was given to the Zonal
Railways to engage casual labour to carry out more than 16 activities, which
were also listed in the Report. Depending on the affordability of individual
Railways, rather than based on real analysis of needs, casual labourers were
engaged to supplement the permanent gangstrength as laid down by the
Special Committee Formula. This had resulted in loss of uniformity of overall
manpower per ETKM among the Railways, apart from substantial increase of
financial burden in the process of giving permanency to the casual labourers
which was necessitated due to the post 1980 social changes. Thus the aim of
bringing about standardisation of manpower utilisation and realisation of
economy could not be achieved. Appendix 2 shows wide variation of number
of trackmen/ETKM among the Zonal Railways.
2.10.2 ETKM is the transformed physical length of track to represent work-loadmeasure by attributing certain weightages to the parameters which control
maintenance requirements such as traffic density, type of formation, annual
rainfall and extent of curvature of track. ETKM was originally evolved so as to
provide a linear relation to gangstrength. Subsequently the same was also
adopted
as
Performance Unit
for
monitoring
expenditure on
track
maintenance. However, as indicated in Appendix 2, maintenance cost per
ETKM is found varying widely among Zonal Railways.
34
(Vol.1)
2.10.3 The reasons as to why manpower per ETKM is varying among Zonal
Railways are given as follows:
2.10.3.1 One ETKM on BG calls for 1.47 men, whereas one ETKM on MG calls for
1.21 men. In a unit comprising of both BG and MG, the practice of merely
summing up ETKMs of both gauges is prevalent for a long time.
This
procedure itself is wrong. ETKM of MG should be multiplied by 1.21/1.47, i.e.,
0.82, before it is added to ETKM of BG, if the intention is to compare different
railways with varying proportions of BG and MG. It is interesting to note that
this lacuna was absent in Maflin'
s Formula of 1931. (Refer para 1.1 of
Appendix 1)
2.10.3.2 As and when modernisation of track structure and maintenance method is
implemented in a stretch of track, gangstrength for that portion is reduced in
accordance with the correction factor K stipulated by the Special Committee.
But the ETKM remains unchanged, since K is external to ETKM. Therefore,
Manpower (computed as per Special Committee'
s Formula) per ETKM goes
on reducing as modernisation proceeds. Thus different railways/units with
varying modernisation cannot be compared, as regards manpower per ETKM.
2.10.3.3 The number of casual labourers engaged for those activities which were not
assigned to permanent gangstrength had no relation to ETKM and have now
become permanent under decasualisation steps taken from time to time.
2.10.4 The reasons for incoherent relation between cost of maintenance and ETKM,
as seen while comparing different railways/units, are as follows:
2.10.4.1 Manpower cost is the principal constituent of total maintenance cost.
Therefore, the same reasons as given in paras 2.10.3.1, 2.10.3.2 and 2.10.3.3
are valid.
2.10.4.2 The cost of renewals in a given stretch of track in a year depends on the age
of track, type of track structure, proneness to corrosion, etc. These factors do
not figure in computing the ETKM.
35
(Vol.1)
2.10.4.3 ETKM incorporates equivalent length of turnout, diamond, trap, etc.
certain other track locations such as
But
SEJs, level crossings, bridge
approaches, requiring additional maintenance efforts have not been
incorporated in the present definition of ETKM.
2.10.4.4 Cost of various inspections, regular patrolling, sporadic security patrolling and
repair works for bridge structures undertaken by PWIs (IOWs on some
railways) do not reflect in ETKM.
2.10.4.5 The cost incurred in renewal of track components per km (or per ETKM)
varies widely among the Zonal Railways depending on the traditionally
evolved norms and practices. Some Zonal Railways have been getting more
allotment on historical reasons and this trend continues in the absence of zero
based approach.
Such railways tend to be more liberal than the other
railways in carrying out renewal and replenishing ballast. The charging of the
cost of ballast inserted whether to Revenue or to DRF is locally decided
depending on availability of funds at the time of allocation under various
heads of account/sanctioned works.
Through renewal of items like
rubberpads, liner, etc. is carried out sometimes under Revenue and
sometimes under DRF. In other words, there is considerable overlap between
revenue maintenance and depreciation renewal. Thus the actual expenditure
booked under Demand No.4 – Minor head 200 gets vitiated among the Zonal
Railways and from time to time on the same railway.
2.11
OTHER MANAGEMENT PROBLEMS REQUIRING SOLUTION
In the field of man management associated with track maintenance, many
problems have arisen:
2.11.1 Decasualisation of labour had become inevitable due to judicial decisions and
for giving social security to men engaged. The justification for decasualisation
has widely varied among various units/zones and it is feared that some
redundancy might have crept in.
While implementing sound manpower
planning, the continuance of decasualised posts is questioned repeatedly and
this has caused anxiety and sense of insecurity among workers. (Annexure A)
36
(Vol.1)
2.11.2 Engagement of safaiwalas to assist gangmen to clean the filth on track in
thickly populated areas has become necessary. But a clear policy decision is
absent in this respect. (Annexure F)
2.11.3 Monsoon patrolling, watching of vulnerable locations and security patrolling
are forming sizable workload for gangs. But the gangstrength as per Special
Committee Formula does not have provision for the same. Need has arisen
to examine as
to whether
these
works
can
be entrusted to outside
agencies and whether such a step may not lead to legal complications.
(Annexure G & I).
2.11.4 Due to fast urbanisation of rural areas, gangmen are not able to perform
arduous duties as in the past. Ageing has caused serious effect on their
physical ability. Need has arisen to examine this aspect and also to find
alternative jobs for incapacitated men. (Annexure J)
2.11.5 In order to limit manpower on our payroll, it has become necessary to identify
some activities which may be executed through contract and this is an issue
affecting industrial relations within the organisation. (Annexure K)
2.11.6 Absenteeism among gangmen has become rampant, as much as 60% in
some P.Way sections.
2.11.7 Whereas mechanisation is being increasingly adopted, the educational profile
of gang staff remains to be deficient.
2.12 With these scenario as backdrop, the Railway Board have constituted the
Committee on Manpower and Cost Norms for Track Maintenance, to ensure
judicious assignment of workload to gangstaff, uniformity of manpower
provision among various units commensurate with workload, optimisation of
manpower,
improvement
of
work
culture,
uniform
degree
maintenance and equitable allotment of funds among units/railways.

IDENTIFICATION AND CLASSIFICATION OF ACTIVITIES
INTRODUCTION
3.1.1 The Special Committee arrived at the manpower factor of 1.47 for BG and
1.21 for MG/NG, by computing the mandays required in a year per km
adopting certain norms of output per manday for the main activities involved in
track maintenance. (Refer para 3.1(a) of Appendix 2). In Annexure IV of the
Special Committee'
s Report, the norms/yardsticks for the principal activities of
track maintenance, as arrived at by five different agencies, have been
tabulated and these have been found to be more or less uniform and taken as
acceptable in the light of the experience of the members of the Special
Committee, as mentioned in paras 3.2 and 3.2.1 of the report, where it is also
stated, "No field studies were conducted by this Committee for arriving at the
norms".
3.1.2 After interacting with field engineers from seven zonal railways, the MCNTM
Committee found that these yardsticks are still valid for most of the track
maintenance activities with reference to conventional track under manual
maintenance. As on 01.04.1999, the track kilometrage (including mainlines
and yard lines) is 85,429 km on BG, 19,158 km on MG and 3,826 km on NG.
Out of this only 40,287 km of BG track has come under machine packing till
01.04.2000. Therefore 45,142 km on BG and entire MG and NG systems,
totalling to 68,126 km of track is manually packed. Therefore the Committee
is of the opinion that even in future on the stretches of manually packed track,
the Special Committee Formula can be continued to be applied but duly
modifying the same, with provisions to cover certain variables left out, as will
be discussed in paras 4.3, 4.4 and 4.5.
3.1.3 The Special Committee Formula stipulates adoption of the manpower factor
(evolved for conventional track) multiplied by the arbitrarily prescribed
Correction Factor K for being applied to modern track. This concept raises
the following doubts:
38
(Vol.1)
•
Operations involved for the maintenance of modern track are entirely
different from those for conventional track.
Is the manpower factor
(1.47 or 1.21) valid for being modified by multiplying with an arbitrary
Correction Factor K, for computing manpower requirement for
modernised track under mechanised maintenance?
•
As the traffic density increases, Traffic Density Factor U increases
correspondingly.
Though U moves up step-by-step, the mid-zone
variation is linear. (Graph-6 may be seen). For manual maintenance,
manpower requirement may increase linearly in order to keep up the
same standard of track. But if a major part of track deterioration can be
rectified by deployment of tie tamping machine and other machines as
required, is there a need to increase the manpower input in the same
proportion as traffic density?
3.1.4 To clear these doubts, it is inescapable to resort to zero based analysis,
supported by field data on the practicable norms for the activities required for
modern track, as well as conventional track.
3.1.5 Therefore MCNTM Committee decided that the first and foremost step is to
list out all the activities involved in track maintenance and to classify them
logically under certain categories.
The second step is to obtain data on
feasible and judicious yardstick for each elementary activity, to relate the
quantum of output to the mandays required.
3.1.6 NFIR and AIRF have taken pains to make complete lists of actvities of track
maintenance in their letters addressed to the Committee (Annexures N & O).
These were first taken into consideration by the Committee.
3.1.7 The interaction with the field officers of seven zonal railways gave a thorough
insight of the ‘Subactivities’ of track maintenance and their categorisation
under main ‘Activities’, in conjunction with tracks of both types, namely
machine packed and manually packed.
39
(Vol.1)
3.2
IDENTIFICATION OF THE TYPES OF TRACK, FOR ANALYSIS OF ACTIVITIES
3.2.1 As experienced by the field engineers and as supported by the field data
brought by them, it is seen that under machine packing the difference in
performance between PRC and other types of sleepers is not very significant.
Moreover all machine packed sections are mostly laid with PRC sleepers.
Therefore the Committee decided that for the catergorisation of subactivities
under main activities of track maintenance, track may be considered only
under two headings, ‘Machine Packed’ and ‘Manually Packed’, irrespective of
the type of sleepers laid.
3.2.2 Likewise, as experienced by the field engineers and as supported by the field
data brought by them, packing need for SWR or LWR track is not much
different from that for non-welded track, which is contrary to theoretical
expectations. This situation exists because,
•
Large number of rail-welds have geometrical defects in top table level
and/or gauge face alignment and the sleepers at these locations require
packing often.
•
Switch expansion joints (SEJs) in LWR track require frequent attention,
due to inherent deficiency in design. (A few accidents of serious nature
have taken place due to breakage of SEJs).
•
Repair welding works are carried out, following failures/cracks taking place
at welds or in parent rails. Excessive thermal stresses in LWRs cause
incidence of such failures at a larger rate than in non-welded rails.
•
Repair welding works are carried out often, even before weld
failures/cracks take place, in the interest of safety, to eliminate welds with
metallurgical or geometrical defects.
•
Destressing of LWR panels periodically is an extra activity.
Due to these reasons, manpower requirement for attending to defects arising
due to intensity of traffic is the same, irrespective of the track having LWR,
SWR or fish-plated rails, under the present conditions, eventhough the nature
of activities may be different. Realising the problems arising due to rail-welds
of poor quality and deficiency in the designs of SEJ, steps have been
40
(Vol.1)
undertaken to improve the quality of welds and SEJs through technologically
superior inputs. In this context, it is relevant to refer Para 15 of Summary of
Recommendations in Part I of ‘Report of the Railway Safety Review
Committee, 1998’, wherein Railway Board have been asked to improve the
technology of alumino thermic welding to international level within a time span
of one year. MCNTM Committee recommends that the effort to improve rail
welds should receive adequate thrust and that a review should be made after
5 years from now, so as to reduce maintenance efforts and manpower
requirement thereof for SWR/LWR track. Therefore the Committee decided
that the track need not be classified, for the present, based on LWR or SWR
or fish-plated, for evolving manpower requirement.
3.2.3 During interaction with field engineers, it was revealed that the factors
governing maintenance activities and the consequent manpower requirement
are significantly different between non-suburban mainlines (machine packed)
and suburban main lines (machine packed), even though the list of
maintenance subactivities are more or less common for these two types of
lines. Therefore the Committee decided to classify exclusively ‘High Density
Suburban Track’ (the term to be defined in Chapter 5), for the purpose of
categorising subactivities of track maintenance in a different way as compared
to non-suburban track.
3.2.4 Summing up the contents of paras 3.2.1 to 3.2.3, the Committee decided that
the activities of track maintenance will be separately identified for three types
of track, namely,
3.3
•
Machine packed non-suburban track
•
Manually packed non-suburban track
•
Machine packed high density suburban track
IDENTIFICATION OF ACTIVITIES OF TRACK MAINTENANCE
3.3.1 The Committee considered the practices of letting out on contract some of the
maintenance activities as adopted on various zonal railways and on Konkan
41
(Vol.1)
Railway.
Contents of Railway Board’s letters No.87/W6/TK/12 dt.
08.88
(Annexure L) and No.97/E/MPP/1/9 dt.13.10.97 (Annexure M) on this subject
were also considered. Accordingly, the Committee have identified activities
which can be contracted out or which have to be appropriately performed by
other departments, who may in turn get those works done through contract
system if necessary. These are brought out in para 8.10, giving a list of 20
activities, which do not call for any gangstrength requirement. After taking into
account such off-loading, the Activities category-wise to be performed by track
maintenance work force were identified.
3.3.2 The Committee decided that for any of the three types of tracks mentioned in
para 3.2.4, the activities of track maintenance will be catergorised as follows:
3.3.2.1 PRIMARY MAINTENANCE ACTIVITIES : These are directly related to P.Way
maintenance, needing manpower based on continuous length of track, further
classified as follows:
•
Activities T (Affected by Traffic density):
These are aimed at achieving
safety and acceptable running quality, commensurate with the loads and
speeds carried.
•
Activities R (Routine: Unaffected by traffic density):
These
are
for
maintaining track, formation and other integrated assets, which are of
routine nature, but quite important for train operation and for achieving
reliability and long life of assets.
3.3.2.2 AUXILIARY MAINTENANCE ACTIVITIES : These are related to upkeep of
P.Way section as a whole, needing manpower based on localised problems,
special features and geographical nature of P.Way section, further classified
as follows:
•
Activities M (Miscellaneous): For these activities, the quantum of work
arising in the P.Way section can be assessed on a universally adoptable
basis and the yardstick relating mandays requirement to output is
rationally stipulated for each subactivity.
42
(Vol.1)
•
Activities S (Site-specific):
For these activities, the quantum of work
arising varies from location to location depending on site-specific features
of the P.Way section and the yardstick is stipulated generally based on
past experience.
Each of the Activity T, R, M & S may be further broken down into ‘subactivities’.
3.3.3 Sub-activities under each Activity
3.3.3.1 As regards Activity T and R, the subactivities will be as follows, for the three

The reasons for grouping subactivities in different ways under the Activities T,

3.3.3.2
As regards Activity M, the subactivities will be as follows and these are
common for any of the three types of track.
M.1 Monsoon patrolling
M.2 Hot weather patrolling for LWR track
M.3 Cold weather patrolling for LWR track
M.4 Watching of vulnerable locations

3.3.4 All these Activities (mentioned in paras 3.3.2) can be remembered as
T–R–M–S. The intention of the Committee is to find norms for manpower for
44
(Vol.1)
each of the sub-activities of these four Activities. Chapters 4, 5 and 6 deal in
detail the evolving of the “Rational Formulae” for manpower requirement for
Activities T, R, M and S, based on the norms fixed for the individual subactivities following inter-action with field staff, scrutiny of earlier reports and
application of the experience of the technical members of the Committee.

EVOLVING OF NORMS FOR MANPOWER REQUIREMENT FOR
ACTIVITIES T AND R (NON-SUBURBAN SECTIONS)
4.1
INTRODUCTION
4.1.1 Unit chosen for manpower
The nature of maintenance activities required for track undergoes change
week after week.
If the track engineer does not exercise control, the
manpower requirement per week will fluctuate quite abruptly.
He should
choose and carryout one or more activities on day-to-day basis, so that the
available manpower is optimally utilised on all days. During interaction with
the Supervisors and Engineers, the Committee found that they are fully aware
of the resource-levelling as regards manpower. For example, when monsoon
patrolling is being carried out, they regulate other activities.
They are
concerned about ‘Mandays’ as the quantum of labour resource. Therefore the
Committee decided that manpower requirement for the various sub-activities
under Activities T, R, M & S should be computed in terms of mandays and the
norms prescribed should yield the result in mandays per annum. This will be
a more precise unit than Manpower Factor, as used in the existing Special
Committee Formula, namely 1.47 for BG and 1.21 for MG.
4.1.1 Name for the formulae evolved – “The Rational Formulae”
In the past, gangstrength formulae had names such as, Maflin’s Formula,
Modified/Revised Maflin’s Formula (some times as Lobo Committee Formula)
and Special Committee Formula. The original terms of reference to MCNTM
Committee is to modify Special Committee Formula. Instead of going in for
long name ‘Modified Special committee Formulae’ for the formulae evolved by
MCNTM Committee, it was decided that the new name will be “Rational
Formulae”. The name conveys fully that the formulae have been evolved on
rational basis.
46
(Vol.1)
4.2
STUDY ON NON-SUBURBAN MAIN LINE, MACHINE PACKED (BG)
4.2.1 Details of field study and tabulation of data
4.2.1.1 The Committee interacted with Junior Engineers, Section Engineers,
Assistant Engineers and Divisional Engineers on six Zonal Railways, namely,
Northern, Southern, Western, South Eastern, Eastern and South Central
(given in the chronological order of the meetings). 14 non-suburban sections
on BG were studied in detail, by collecting information on the norms for
mandays requirement for each subactivity of track maintenance, as in vogue
on these sections.
The yardsticks suggested by NFIR and AIRF in their
letters addressed to the Committee (Annexures N and O) were also examined
in detail and compared with what is practised in the field, not only for machine
packed track but also for manually packed track, on non-suburban and
suburban lines and on BG, MG & NG.
4.2.1.2 The heading details of Tables 1 to 14 give the locations of the sections
studied, traffic density, track particulars etc. The format of Tables 1 to 14 has
provision to record mandays requirement for subactivities under Activities T
and R as identified in para 3.3.3.1. In addition, there are also provisions for
recording manpower details for the following activities/subactivities:
a) Activity L: This comprises of 4 subactivities, namely, boxing of ballast
(periodical work to ensure lateral strength for LWR track), destressing, hot
weather patrolling and cold weather patrolling. The Committee collected data
on these four subactivities in the initial stages. But later on, based on the
information collected and deliberations, the Committee decided to drop the
Activity L while unifying the activities and subactivities to evolve norms in the
final shape. Hot and cold weather patrolling were shifted to Activity M, so that
in low temperature variation zones, engineers can decide as to whether or not
to carry out LWR patrol. Boxing of ballast and destressing were dropped,
because these subactivities can be managed by utilising the labour saved in
LWR track due to absence of fish plated joints, inspite of what has been
explained in para 3.2.2, since the manpower requirement for these two
subactivities is not significant.
47
(Vol.1)
b) USFD testing :
This was initially considered as a subactivity, since some
zonal railways were deputing gangmen to assist USFD team. Later on, it was
realised that most of the zonal railways had exclusive Group D staff for this
purpose.
Hence this subactivity was finally dropped while unifying the
activities.
c) Painting of weld collars: Some zonal railways were utilising gangmen for
this work. Subsequently the Committee decided that this can be executed
through contract.
Hence this subactivity was dropped while unifying the
activities.
4.2.1.3 All the fourteen sections studied are machine packed.
However Track
structure varied widely from 52kg/60kg LWR on PRC sleepers to 52kg/90R
SWR/Free rails on ST sleepers.
However, majority of track had PRC
sleepers. The traffic density varied from 12.5 GMT to 68 GMT. Single line
o
o
section with 48 GMT on KK line with curves of 6.5 to 8 over 59% of length
was also included.
4.2.1.4 The track engineers had been asked to come prepared for interaction with the
Committee, along with their records of manpower utilisation, manpower lost
due to leave, sickness and absenteeism, etc. No attempt was made to give
them any proforma in advance, apprehending that this will encourage a
tendency to project unrealistic details. By cross questioning in person, real
picture was obtained as far as possible. Cordial atmosphere prevailed for
enabling free flow of information and arguments.
Some Track Engineers
admitted that certain annual tasks could not be completed on account of
absenteeism; but they were clear in expressing the norm/yardstick for subactivities. The mandays requirement recorded in Tables 1 to 14 indicate the
requirement, but not necessarily the actual availability.
4.2.1.5 Most of the information
recorded during interaction were condensed in
Tables 1 to 14. Information which could not be accommodated in the tables,
finds place in Appendix 3, which is a narration of the discussions with Track
Engineers.
48
(Vol.1)
4.2.1.6 The Committee did not find it necessary to collect detailed information on
Activities M and S; but the yardsticks and practices in vogue were generally
noted, though not recorded in any tabular form.
Since the manpower
requirement for Activities M and S will vary from section to section depending
on the specific local features, no purpose would have been served by
tabulating data on Activities M and S and by comparing them.
4.2.2 Having tabulated the data for Activities T, R and L in Tables 1 to 14, the
mandays requirement per annum were computed. Table 15 gives an abstract
of all the figures pertaining to 14 sections. Table 16 gives the analysis of the
results.
4.2.3 The Committee, with the intention to avoid long discussions in the main
report, have incorporated remarks and footnotes in Tables 1 to14 and Table
16. A close study of the figures in Tables 1 to 16 is necessary to appreciate
the divergent scenario, but still with certain uniform features. If the distorted
figures are given less weightage, a clear picture emerges out as explained
further.
4.2.4 The plot of Mandays requirement for Activity T (affected by Traffic density) Vs
GMT is at Graph 1. The foot notes may be seen. The regression analysis
yields the result.
Mandays/yr for Activity T = 80 + 2.3 GMT
4.2.5 As regards Activity R (Routine – Unaffected by Traffic density), the plot of
Mandays Vs GMT may be seen at Graph 2, along with the footnote. The
mandays requirement per annum has been reckoned as 196.
4.2.6 As regards Activity L (exclusively for LWR), the plot of Mandays Vs GMT may
be seen at Graph 3. There is too much of scatter, since some of the Sectionin-charges had projected unrealistic requirement.
Anyway, Activity L was
ultimately dropped due to reasons explained in para 4.2.1.2(a).
49
(Vol.1)
4.2.7 As regards Total
mandays
Graph 4 may be seen.
requirement for Activities (T+R+L) Vs GMT,
There is too much of scatter.
The Committee is
however satisfied that when the manpower for Activities T and R were
individually segregated and analysed, useful result has been obtained.
4.2.8 Graph 5 gives the proportion of manpower requirement for Activity T to that
for Activity R, plotted for different sections.
Manpower requirement is
dependant on work-culture and may vary from location to location.
If the
same work-culture governs Activity T and R in each location, it was expected
that a linear trend will be obtained with increasing GMT.
But the results
actually obtained do not lead the Committee to any conclusion.
4.2.9 In order to validate the mandays requirement for the activities T and R as
derived by the analysis, a tabular statement namely Table P, was prepared for
a section with 20 GMT. Judicious values of norms for the individual subactivities were adopted based on the analysis of Tables 1 to 14.
4.2.9.1 In Table P, the total of mandays for Activity T works out to 126, which tallies
with the norm 80 + 2.3 GMT.
4.2.9.2 In Table P, the following changes have been made with respect to the format
of Tables 1 to 14:
•
Subactivity R.2: The periodicity of shallow screening has been changed
as 5 years instead of 3 years. This is because, after the steam traction
vanishing, contamination of top layers of ballast by ash has reduced.
•
Subactivity R.4: The average spacing of level crossings has been adopted
as 1.5km instead of 2km. This is because, on Indian Railways, there are
40,329 level crossing over 62,809 route kilometre, (refer Year Book 199899) giving an average spacing of 1.5km.
•
Activity L and Subactivities ‘USFD testing’ & ‘Painting of weld collars’ have
been dropped as already explained in para 4.2.1.2.
From Graph 2 it is seen that the reasonable value of mandays requirement for
Activity R is 196. But this is based on the data over 14 sections assuming 3
50
(Vol.1)
years periodicity for shallow screening. By changing this as 5 years, mandays
saved will be
1660/(6x3) – 1660/(6x5) = 37
Therefore the reasonable value of 196 should be changed as 196 - 37=159.
Accordingly 159 mandays have been judicially distributed among subactivities
R.1 to R.12 in Table P, as per acceptable individual yardsticks.
4.2.10 To sum up, the Rational Formulae for machine packed mainline are:
Mandays/yr, for Activity T
Mandays/yr, for Activity R
Mandays/yr for Activities T and R
4.3

STUDY ON NON-SUBURBAN MAIN LINE: MANUALLY PACKED (BG)
4.3.1 Having arrived at the norm for manpower for Activities T and R in machine
packed section in the linear form, namely '
239 + 2.3GMT'
, an attempt was
made to evolve a similar form for manually packed section. This is possible
as could be seen on the plotting for BG on Graph 6.
4.3.2 The Special Committee Formula is based on well evolved yardsticks for the
sub-activities, as already explained in para 3.1.1, for manually maintained
track.
Therefore this formula should be valid for Activities T and R put
together, since the sub-activities of T and R are more or less the same as
those indicated in Special Committee'
s Report reproduced in para 3.1(a) of
Appendix 1. Referring Graph 6, the step-by-step variation of U with respect to
GMT (which is really illogical) has been substituted by a mid-zone linear
variation, yielding U=1.4 for GMT = 22.5 and U = 1.0 for GMT = 2.5. Thus U
is governed by the linear formula U = 0.95 + 0.02GMT.
Mandays/yr = 0.95 x M x 295 x U where M is the manpower factor 1.47 and
295 is the number of working days in a year as per Special Committee
formula.
51
(Vol.1)
Thus, Mandays/yr = 0.95 x 1.47 x 295 x (0.95+0.02GMT) = 391+8.24GMT (for
Activities T and R combined)
4.3.3 As an attempt to validate the mandays requirement for Activities T and R as
derived from the above expression, tabular statements were prepared for
sections with 2.5 GMT and 22.5 GMT as shown in Tables P1 and P2
respectively. Judicious norms for the individual sub-activities were adopted
based on the analysis of Tables 1 to 14, also adopting the norms for the
principal sub-activities given in Special Committee'
s Report and also
supported by the experience of the technical members of the Committee.
It is seen that mandays/year for Activity R = 168, from Tables P1 and P2.
Total mandays/year for 2.5 GMT and 22.5 GMT sections also tally with figures
412 and 577, as yielded by the expression 391+8.24GMT.
Mandays/yr for Activity T = (391-168)+8.24GMT
= 223+8.24GMT
Mandays/yr for Activity R = 168
4.3.4 The Rational Formulae arrived at, as in paras 4.2.10 and 4.3.3 are
reproduced:
For machine packed track, Mandays/yr./km = 303 + 2.3 GMT
For manually packed track, Mandays/yr./km = 391 + 8.24 GMT
Comparison of these two expressions, clearly brings out the advantage of
mechanised maintenance. Manpower variation per GMT is 2.3 for machine
packed track compared to 8.24 for manually packed track, apart from the fact
that the constant component of the formula is also less in the first case.
4.3.4.1 The economy achieved with respect to manpower and maintenance cost per
kilometre, by applying the Rational Formulae to manually packed and
machine packed tracks, has been dealt in para 4.12, supported by
calculations at Appendix 5.
52
(Vol.1)
4.3.4.2 It would be also of interest to compare the Rational Formulae for machine
packed track with the Special Committee Formula applying correction factors
K. Appendix 6 gives such an evaluation.
4.4
STUDY ON NON-SUBURBAN MAIN LINE: MANUALLY PACKED (MG)
4.4.1 A similar exercise was carried out for MG also, as self explained in Graph 6.
Two sections with GMT = 7.5 (U = 1.15) and GMT = 2.5 (U = 0.95) were taken
and the expressions derived are
U = 0.85 + 0.04 GMT
Mandays/yr. = 0.95 x 1.21 x 295 x (0.85 + 0.04 GMT)
= 288+13.56 GMT (For Activities T and R combined)
Tables Q1 and Q2 are validating this expression for the two sections with
GMT = 2.5 and GMT = 7.5 respectively.
It is seen that mandays for Activity R = 128, from Tables Q1 and Q2. Total
mandays/yr for the two sections also tally with the figures 322 and 390 as
yielded by the expression 288 + 13.56GMT.
Mandays/yr for Activity T = (288 – 128) + 13.56 GMT
= 160 + 13.56 GMT
Mandays/yr for Activity R = 128
4.5
STUDY ON MANUALLY PACKED NG MAIN LINE
4.5.1 As per Special Committee Formula, the value of U has been prescribed as
0.8 for sections with daily train density of more than 10 and as 0.6 for less
train service.
As per the details obtained from W.Rly, Dabhoi – Miagaon
section carries 0.4 GMT with 10 trains/day and Samni – Dahaj section carries
53
(Vol.1)
0.04 GMT with 2 trains/day. Therefore U = 0.8 for GMT = 0.4 and U = 0.6 for
GMT = 0.04. We get the relation U = 0.578 + 0.556 GMT.
Mandays/annum = 0.95 x 1.21 x 295 (0.578 + 0.556GMT)
= 196 + 188GMT ( for Activities T and R combined)
For section with GMT = 0.4, mandays/yr = 271, which can be split as 180 and
91 for Activities T and R respectively. (Table R1)
For section with GMT = 0.04, mandays/yr = 203, which can be split as 112
and 91 for Activities T and R respectively. (Table R2)
Mandays/yr for Activity T = (196 – 91) + 188 GMT
= 105 + 188GMT subject to a maximum value
of 180 which corresponds to GMT=0.4. This upper limit has been imposed,
because for NG maximum value of U is 0.8 as per Special Committee
Formula and this limit is not exceeded in actual practice also.
Mandays/yr for Activity R = 91

STUDY
REGARDING
ENHANCING
OF
MANPOWER
FOR
BAD
FORMATION, CURVED ALIGNMENT AND RAINFALL
The Committee Members are of the opinion that the proven practice of
enhancing of manpower as per factor (1+A+B+C) given in the Special
Committee'
s Formula should continue, based on their own experience and on
what has been expressed by majority of the field engineers. Some of the field
engineers pleaded for increasing the values of these factors.
However the
Committee Members are of the opinion that these factors need not be
increased and that the factor (1+A+B+C) should be applied to the manpower
requirement for Activities T only, since the related sub-activities only are
affected due to features such as bad formation, sharper curvature and
excessive rainfall. In case these features pose extraordinary maintenance
problems in certain specific stretches, the manpower requirement can be
assessed under subactivities S.4 and S.5. (Refer Para 3.3.3.3)
54
(Vol.1)
4.6.1 Formation Factor A
The Special Committee Formula of adopting A = 0.1 and A = 0.2 for bad and
very bad soil respectively may continue.
If there are banks necessitating
more than 20% extra input, remedial measures should be carried out on
priority.
4.6.2 Alignment Factor B
As per Special Committee Formula, the value of this factor assumes a sudden
o
o
o
jump of 0 to 0.25 for 1.5 curve on BG, 3 curve on MG and 5 curve on NG,
which is not logical. As gathered from track engineers, maintenance effort
o
o
o
increases right from 1 curve on BG, 2 curve on MG and 3 curve on NG.
Therefore it is reasonable to adopt the following values for B:
o
BG:
B = 0 upto 1 curve, increasing from 0 to 0.25 linearly as curvature
o
o
increases from 1 to 2 and thereafter constant at 0.25.
MG:
B = 0 upto 2 curve, increasing from 0 to 0.25 linearly as curvature
o
o
increases from 2 to 4 and thereafter constant at 0.25.
NG:
B = 0 upto 3 curve, increasing from 0 to 0.25 linearly as curvature
o
o
increases from 3 to 7 and thereafter constant at 0.25.
o
o
The recommended changes are represented in Graph 7. From this it would
be seen that the overall effect of these proposed changes on manpower will
be negligible, however leading to rational distribution of manpower.
4.6.3 Rainfall Factor C
This factor in Special Committee Formula is 0 upto annual rainfall just short of
200cm and suddenly assumes a value of 0.1 for annual rainfall of 200cm.
The factor then gradually increases to 0.2 at a rainfall of 300cm. For rainfall
of more than 300cm, C remains constant at 0.2. Annual rainfall of 200cm
55
(Vol.1)
itself is considered heavy to create track problems. A sudden jump in the
value of C from 0 to 0.1 at 200cm rainfall is not logical.
The Committee
recommends that value of C should start from 0 at 150cm annual rainfall,
increase linearly to 0.2 for rainfall of 300cm and thereafter remain constant.
The shape of the proposed variation of C, as could be pictorially seen in
Graph 8, has been so decided that the manpower gets distributed more
rationally, without overall increase.
4.7
STUDY ON RUNNING YARD LINES
4.7.1 According to Special Committee'
s Formula, run-through line of yard is treated
in par with mainline, duly applying the factors U, A, B and C. The actual
quantum of freight traffic passing on run-through loop will be only a fraction of
the traffic in the section.
Moreover the trains enter run-through loops at
restricted speed. Therefore the Committee feel that none of the factors U, A,
B or C need be applied to the length of running yard lines. The Committee
found that in actual practice, a fixed yearly schedule of attention is imparted to
running yard lines and therefore the entire maintenance activity can be
regarded as Routine Activity.
4.7.2 The following Tables give the details of subactivities, norms and manpower
requirements for running yard line of 1km length:
Table S
:
BG, machine packed :
177 mandays/annum
Table S1
:
BG, manually packed :
297 mandays/annum
Table T
:
MG, manually packed :
228 mandays/annum
Table U
:
NG, manually packed :
153 mandays/annum
4.7.3 Running yard line may be regarded somewhat as mainline over which the
effect of traffic in terms of GMT tends to be negligible. For mainline track,
formulae for manpower requirement for Activities T and R have been already
arrived at and these may be adapted for running yard lines as follows:
56
(Vol.1)
BG, machine packed : 239 + 2.3GMT.
If GMT=0, this becomes 239.
BG, manually packed : 391 + 8.24GMT. If GMT=0, this becomes 391.
MG, manually packed : 288 + 13.56GMT. If GMT=0, this becomes 288.
NG, manually packed : 196 + 188GMT. If GMT=0, this becomes 196.
4.7.4 Manpower requirements as decided through Tables S, S1, T and U given in
para 4.7.2 work out to 74%, 76%, 79% and 78% respectively of the values
arrived at in para 4.7.3.
Therefore the values given in para 4.7.2 are
reasonable, considering the fact that the slower speed on loop line will cause
much less deterioration to track than that caused by higher speed on
mainline.
4.8
STUDY ON NON-RUNNING YARD LINES
As such there exists no BG machine packed track on non-running yard line.
The Committee feel that the periodicity of maintenance of non-running line
can be 1½ times that for running yard lines. Therefore 2/3rd of the manpower
requirement for running yard lines will be adequate. Based on this argument
the following manpower can be provided for non-running yard lines:
4.9
BG manually packed : 2/3 x 297 =
198 mandays/yr/km
MG manually packed : 2/3 x 228 =
152 mandays/yr/km
NG manually packed : 2/3 x 153 =
102 mandays/yr/km
STUDY ON TRACK CONNECTIONS AND LAYOUTS
In the Special Committee Formula, equivalent lengths of plain track
corresponding to various types of layouts have been given. (Refer para 2.3 of
Appendix 1).
The Committee recommend that this concept borne out of
experience be retained.
The Committee examined whether equivalent
lengths for SEJs and Level Crossings be prescribed to cater for the extra
maintenance called for, as envisaged in the Report of the Committee for
Rationalisation of Costing Permanentway Activities.
The Committee found
that this is not necessary in as much as the manpower requirement to
57
(Vol.1)
maintain one SEJ per km and one level crossing at every 1.5 km have been
already taken into account while assessing the manpower requirement per km
of running line track.
4.10
CALCULATION OF GANGSTRENGTH FROM THE MANDAYS REQUIRED
4.10.1 The mandays requirement is computed as per the Rational Formulae derived
in the previous paragraphs, covering Activities T and R.
In addition, the
requirement for Activities M and S is also computed as per the norms derived
in Chapter 6. The total mandays MT thus calculated for Activities T, R, M and
S does not include the following:
a.
Leave reserve of 12.5% for the mandays MT.
b.
Gangmates & Keymen and leave reserve for these posts.
c.
Gatekeepers and Leave Reserve Gatekeepers.
d.
Artizans, such as blacksmith, carpenter, fitter, mason etc. and khalasi
helpers for the artizans.
e.
Trolleyman, Storechaser, Watchmen for the P.Way section’s main
depot, Office staff.
f.
Staff for USFD team.
g.
Supervisors, Technicians, Helpers and Khalasis for the maintenance
and operation of on-track machines, such as, tie-tamper, dynamic track
stabiliser, ballast regulator, ballast cleaning machine, rail grinding
machine,
mobile
flash-butt
welding
machine,
track
relaying
portal/machine, etc. (Instructions contained in Railway Board’s letters
no. 89/Track-III/TK/77 dated 13.12.1990 and 3.1.1991 will decide the
manpower required for these machines.
The type and number of
machines required for each Railway will be decided by the Chief
Engineer and Railway Board based on the gross workload.)
4.10.2 It is the common practice to provide for leave reserve for the posts of
Gangmates and Keymen in the cadre of gangman.
58
(Vol.1)
4.10.3 In a year of 365 days, the total number of working days works out to 290, after
deducting the following holidays and restdays:

4.11 MANPOWER REQUIREMENT FOR MOBILE MECHANISED UNIT (MMU)
Though the total mandays MT excludes manpower elements for items a to g
mentioned in para 4.10.1, it does include the manpower requirement for
Mobile Mechanised Unit (MMU). This will be elaborated in the following paras,
which can be better appreciated by perusing the Report on the Committee’s
visit to Konkan Railway at Appendix 4.
4.11.1 The following functions will be assigned to MMU: (Based on Annexure XI of
Report of CMMDTM (Feb.95) referred in para 1.1.3 and the observations
made on Konkan Railway.)
59
(Vol.1)
a.
Need-based spot tamping
b.
In-situ rail welding
c.
Casual renewal and repairs except planned renewals (which will be
contracted out).
d.
Overhauling of level crossings.
e.
Replacement of glued joints.
f.
Rail cutting, drilling and chamfering.
g.
Permanent repairs to fractures.
h.
Creep or gap adjustment involving use of machines.
i.
Destressing of LWR/CWR.
j.
Loading/unloading of materials.
k.
Reconditioning of turnouts.
l.
Minor repairs to the equipments of MMU.
4.11.2 In actual practice, functions such as c, f, g and j may have to be shared
between sectional gangs and MMU. For instance, if a rail fracture or weld
failure occurs, the sectional gang has to start the repairs, without waiting for
MMU.
Likewise, if a low joint or SEJ requires urgent attention, if a kink
develops in a curve, if immediate renewal of sleeper or bridge timber is
needed, or, if some material has to be handled for such emergency work, the
sectional gang has to swing into action. In other words, some subactivities
under Activities T and R are jointly performed by sectional gangs and MMU,
whereas some other subactivities can be entirely entrusted to MMU.
4.11.3 The equipments needed for MMU are as follows: (Based on Annexure XII of
Report of CMMDTM (Feb.95) referred in para 1.1.3)

tamping with lifting/lining:

61
(Vol.1)
4.11.4 It would be seen that all the equipments listed above except item 11, namely,
light tamping equipment, will have to be procured for track maintenance
activities and have to be used by sectional gangs, even if MMU is not formed.
Use of light tamping equipment is unique for MMU. This can be either of the
following types:
•
•
Off-track tampers with power/compressed air generating unit.
On-track spot-tamping machine of optimal capacity, such as MP-2000.
Further a MMU has to move over the jurisdiction of an Assistant Engineer or
even over a longer stretch. Their mobility has to be accomplished by utilising
one or more of the following types of vehicles:
•
•
•
Road vehicle
Road-cum-rail vehicle
Rail vehicle
These vehicles may be considered to be covered under item L, namely, ‘Any
other equipment considered necessary by the Chief Engineer’.
Indian Railways are still in the process of standardising equipment for spottamping. It is possible to dovetail into one, rail-borne mobility vehicle and ontrack tamping gadgets.
The mobility vehicles and spot-tamping equipment can be termed as
“Speciality Equipment of MMU” and this excludes other equipments kept and
transported in the vehicle, which are essential even for a set-up with sectional
gangs only. The cost of Speciality Equipment of MMU (SEMMU) should be
such that some overall economy is achieved when MMU is formed out of
sectional gangs.
4.11.5 In none of the 14 sections studied by the Committee, MMU has been
deployed and the manpower assessed covers the subactivities which will be
performed by MMU, if installed in future. Manpower norm for machine packed
BG track evolved from the field data collected, is therefore deemed to cover
the workload of MMU. These norms are reproduced as follows:
For machine packed mainline (BG),
62
(Vol.1)
Activity T:
Mandays/year
= (80+2.3GMT)
(para 4.2.4)
Activity R:
Mandays/year
= 159
(para 4.2.5)
For machine packed running yard line (BG),
Activity R:
Mandays/year
= 177
(para 4.7.2)
4.11.6 Referring Table P which gives the break-up of mandays for various activities
for machine packed main line (BG), the following subactivities and the
manpower thereof may be assigned to the workload of MMU:
Activity T:
Slack attention to

4.11.8 The mainline dealt in Table P carries 20 GMT, calling for 126 mandays for
Activity T as a whole, out of which 63 mandays correspond to MMU workload
and it amounts to 50% of 126. Therefore the expression for MMU mandays
is 0.5(80+2.3 GMT) or (40+1.15 GMT), as far as Activity T is concerned.
63
(Vol.1)
Thus for a given length LM (km) of machine packed mainline BG track,
Equivalent MMU mandays = LM(40+1.15 GMT)(1+A+B+C) + (LMx35)
If a length of LY (km) of machine packed running yard line also exists, (LYx35)
has to be added.
The general expression for a P.Way subdivision/division having assorted
length of LM and LY will be:
Gross Equivalent MMU mandays, i.e., GEMM
= Σ LM (40+1.15GMT) (1+A+B+C) + 35Σ LM + 35 Σ LY
4.11.9 Method to decide the strength and composition of MMU
The annual emoluments of GEMM should be calculated, duly considering the
basic pays of three grades, namely, Sr.Gangmen, Gangmen Gr.I and
Gangmen in the ratio 20:55:25 and enhancing it by 12.5% for leave reserve.
It should be the aim to achieve 20% saving in expenditure by way of installing
MMU.
80% of annual emoluments of GEMM = Annualised cost of SEMMU + Annual
emoluments of MMU staff.
Since the Speciality Equipments of MMU are yet to be standardised, Railway
Board, in due course, should stipulate the provisional standard equipment and
their cost and notify the procedure for calculating the annualised cost of
SEMMU. The procedure of calculating annualised cost of machines as given
in Board’s letters No. 92/Track III/TK/15 dt. 29.04.92 and 16.06.92 can be
adopted. Alternatively, Board may notify every year, directly the annualised
cost of each equipment of SEMMU, as they do for the cost of various P.Way
materials for being adopted in the track renewal estimates.
64
(Vol.1)
While calculating the annual emoluments of MMU staff, the following cadre
structure and grades can be adopted, duly taking into account the fact that
they earn more of travelling allowance by virtue of the nature of their job:
Technicians 20%:
Technician Gr.III
Technician Gr.II
Technician Gr.I
Master Craftsman
30% of 20%=6%
30% of 20%=6%
35% of 20%=7%
5% of 20%=1%
Rs.3050-4590
Rs.4000-6000
Rs.4500-7000
Rs.5000-8000
80% of 80%=64%
20% of 80%=16%
Rs.2650-4000
Rs.2610-3540
Assisting staff 80%:
Khalasi Helper (Gangmen Gr.I)
Khalasis (Gangmen)
The ratio 20:80 for distribution among Technicians and Assisting staff may be
modified, such as 30:70, by the Chief Engineer, depending on the nature of
jobs entrusted to MMU, extent of modernisation implemented for track
structure and the degree of sophistication of MMU equipments.
4.11.10 The posts of artizans and helpers mentioned in para 4.10.1(d) do not form
part of MMU. They are required in any case to assist sectional gangs, moving
from gang to gang within P.Way section, whereas MMU will move over
Assistant Engineer’s jurisdiction or over even a longer stretch, if attached to
on-track spot attention tamper.
4.11.11 It is also recommended by the Committee that the guidelines given herein to
calculate GEMM need not be considered rigid. The apportioning of mandays
for MMU workload, out of the mandays required for Activities T & R, as
indicated in paras 4.11.6 and 4.11.7 can be considered to be flexible and it
depends on the field conditions and progressive success of MMU. In addition,
some of the subactivities pertaining to manually packed stretches (such as,
part of through packing and slack packing, casual renewals, handling of
materials, overhauling of level crossings, bridge timber renewal) can also be
transferred to MMU, if such manually packed stretches adjoin machine
packed stretches. Thus, the Chief Engineer can increase the quantum of
65
(Vol.1)
GEMM and change the cadre structure of MMU staff, from time to time,
however ensuring that
•
Atleast 20% economy is achieved due to the formation of MMU,
considering the activities transferred from sectional gangs to MMU.
•
Mandays derived from sectional gangs is curtailed by GEMM, by reducing
sectional gang strength.
Having studied the functioning of Mobile Maintenance Gang of Konkan
Railway and the pilot scheme of MMU launched at Aligarh, N.Rly, the
Committee have put forth these recommendations, which will facilitate,
4.12
•
faster mechanisation
•
better manpower planning
•
enrichment of job contents for gangmen
•
improved career planning for gangmen
QUANTIFICATION OF SAVINGS DUE TO MACHINE PACKING
4.12.1 Attention is drawn to item (g) of para 4.10.1. For creating posts for operating
heavy machines or for meeting the annualised expenditure of these
machines, sectional gangmen as justified by the Rational Formulae will not be
surrendered. Only MMU is carved out of sectional gang strength, effecting
20% economy as indicated in para 4.11.9. If machine packing is introduced to
replace manual packing, mandays requirement will be calculated by using the
formula (239+2.3GMT), in lieu of (391+8.24GMT) used for manually packed
track.
Accordingly, gang strength reduces in an appropriate manner, on
account of packing with heavy on-track machines.
4.12.2 The calculations at Appendix 5 quantify the savings that can be achieved due
to introduction of LWR on PRC sleepers with machine packing in lieu of
conventional track with manual packing, applying the Rational Formulae. The
calculation also illustrates the method of deciding the staff strength of MMU.
The results of the calculations at Appendix 5 are tabulated as follows in
Tables 1 and 2:

The graphs at the end of Appendix 5 provide a visual concept of the savings
achievable by machine packing.
It should be borne in mind that these savings have been computed with
reference to fully manually packed track and these do not reflect the savings
that can be achieved with reference to the present maintenance cost or
manpower as obtained on Indian Railways due to the adoption of the Rational
Forumulae. This is because a major portion of the savings has been already
realised, which remain hidden, as elaborated in para 2.9. The extra savings
in manpower due to implementation of the Rational Formulae in the present
day situation has been brought out in the pilot studies conducted, as
explained in Chapter 9.
4.12.3 In view of the substantial savings achievable through the single aspect of
mechanisation, namely, machine packing, as illustrated above, the Committee
recommends that tie-tamping machines should be introduced on a large scale
67
(Vol.1)
on MG system also, constituting 19,158 km of track, irrespective of the type of
sleepers used, since it is the reality that MG track will continue to exist over a
number of routes for years to come. Moreover the advantage of removal of
drudgery of beater packing should be extended to trackmen working on MG
system also.
4.13
The Rational Formulae have been evolved rationally based on the quantum
and norms for the subactivities of track maintenance, which are transparent in
Tables P, P1/ P2, P3, Q1/Q2, R1,/R2, S, S1, T and U. In these 11 tables, the
individual norms and quantum of works for the subactivities adopted are
based on the following:
•
Scrutiny of the norms and quantum of works as recorded in the field data
collected on 14 P.Way Sections, as recorded in Tables 1 to 14 and
abstracted in Table 16 in a consolidated form.
•
Norms adopted in the Report of the Special Committee (1979) and in
Annexure IV of the same Report.
•
Application of the long experience of the Technical Members of the
MCNTM Committee.
•
Conclusions arrived at by the MCNTM Committee members after
deliberations.
The Rational Formulae incorporate ample in-built flexibility. For example, as
already explained in para 4.2.9.2, the Committee has adopted the frequency
of 5 years instead of the presently adopted 3 years for shoulder screening of
ballast and the mandays requirement has been accordingly computed. This is
a labour intensive and tuff activity which has to be mechanised on priority all
over Indian Railways. As and when modernisation in various subactivities
progresses, some of the subactivities may reduce in quantum or vanish; or
these may require less manpower.
Thus the Rational Formulae can be
amended easily, by recasting the relevant Tables.
4.14
Further, Rational Formulae are so flexible as to encourage formation of MMUs
and to expand the field of activity of MMUs, by which it is possible to achieve
68
(Vol.1)
reduction in overall manpower combined with improvement to cadre structure
and enrichment of job content for trackmen, as brought out in para 4.11.
4.15
The Committee recommend that Railway Board may order review of the
Rational Formulae once in 5 years, to incorporate the effects of
modernisation, such as introduction of more number of shoulder ballast
cleaners, improving rail-weld technology, better design of SEJs, maintenance
free level crossing track structure, etc.

Railway Board should be taken into account and Leave Reserve of 12.5%

EVOLVING OF NORMS FOR MANPOWER REQUIREMENT FOR
ACTIVITIES T AND R (HIGH DENSITY SUBURBAN SECTIONS)
INTRODUCTION
There are some suburban sections in Mumbai area, which have very high
train density. It is very well known that maintenance work in these suburban
sections is quite different and output per manday is less than that achieved on
other sections. Besides, there are certain additional subactivities required to
be performed in these sections. Norms and formulae evolved in Chapter 4 do
not meet the manpower requirement in these sections.
The Committee
therefore decided to evolve different norms and formulae for these suburban
sections of Mumbai, which can be applied to similar suburban sections of
other cities, if qualifying to be termed as ‘High Density Suburban sections’ as
defined in para 5.5.
The committee interacted with the staff responsible for maintenance of
suburban section under Sr.SEs, Thana and Byculla of Central Railway and
Sr.SE, Dadar on Western Railway. The AENs and Sr.DENs of these sections
also participated in the discussions.
5.2
SPECIAL FEATURES OF HEAVILY WORKED SUBURBAN SECTIONS
Maintenance of track in heavily worked suburban sections is much different
from that of non-suburban track because of the following features.
5.2.1 High frequency of trains
On suburban sections of Mumbai, the trains run at nearly 3 to 4.5 minutes
headway during the peak period. The maximum number of trains per hour on
various lines during morning peak period on a sub section is as follows:
71
(Vol.1)
NO. OF TRAINS PER HOUR IN MORNING PEAK
Line
DN Slow Line
UP Slow Line
DN Fast Line
UP Fast Line
Western Railway Central Railway
16
10.5
16.6
12.25
15.6
11.5
17.3
11
With passage of each train, about 3 minutes time is lost and thus the effective
time available for work during the working period reduces considerably. Thus
where the train frequency is more than 10 per hour, the availability of
maintenance time reduces to less than 50%.
5.2.2 Problems due to encroachments
The incidence of heavy encroachments in the vicinity of track in all major
cities particularly in metropolitan cities is consequent to pressure of population
and socio-economic-political conditions. The heavy encroachments near the
tracks affect seriously the drainage and cause frequent disturbance to ballast
section. The track has become a dumping ground for garbage causing a
serious handicap to gangmen. Besides the filth removal is a regular job which
has to be undertaken, necessitated due to nuisance caused by slum dwellers.
5.2.3 Corridor night blocks and integrated mega blocks
Due to very high frequency of trains and insufficient time being available for
maintenance during day time, night maintenance blocks are regularly resorted
to. In addition, 6 hours integrated mega blocks on Sundays are being availed.
The night blocks are essentially used for renewals, tie tamping work, welding
work etc. The mega integrated blocks are used for such of the maintenance
activities (including for traction and signalling) which cannot be done on week
days or in the night block. These works call for deployment of exclusive gang
staff for the track works done in association with Traction and Signalling
departments.
These features of working necessitate a different type of
manning pattern.
72
(Vol.1)
5.2.4 Large number of turnouts
There are very large number of turnouts on the suburban section of Western
and Central Railways. For the purpose of maintenance, Western Railway has
classified the turnouts in A, B, and C categories in accordance with their
importance. On Western Railway there are 486 turnouts on running lines with
a track length of 217 km. Besides there are very large number of special
layouts, viz. diamonds, scissors, diamonds with and without slips requiring
considerable maintenance efforts.
5.2.5 Lack of drainage
Due to construction of large number of buildings on both sides, the track has
virtually become a drain, with water logging in continuous stretches.
situation
is
further
aggravated
due to encroachments, dumping
The
of
garbage/refuse and non-functioning of culverts crossing track. Subsoil water
table is also high in many locations. These have resulted in sinkage of track,
disturbing track geometry. On Central Railway, speed restrictions have been
imposed on certain stretches.
5.2.6 Problems due to extensive track circuits
Due to continuous track circuits, the number of insulated block joints have
increased along with side connections and other equipments creating
impediment to day-to-day maintenance. Additional holes are drilled in the
rails for signalling and traction purposes, due to which rail failures occur more
frequently.
Additional attention is also required for track circuit failure on
account of glued joints or poor drainage conditions.
5.3
TRACK STRUCTURE ON MUMBAI SUBURBAN SECTION
The sections studied for assessing manpower utilisation under Sr.SEs,
Byculla and Thana on the Central Railway and Dadar on the Western Railway
have the following break up of track structure.

The above details would suggest that though reasonable progress has been
made in laying concrete sleepers, still long lengths remain as free rail and not
much work has been done for converting the track into LWR.
The track structure on the suburban section is a mix of wooden and concrete
sleepers and it will take three to four more years to relay the main line track
with concrete sleepers. The analysis of the activities shows that still through
packing is a significant activity in track maintenance on suburban section.
Tie tamping machines are regularly deployed in these sections. The retentivity
is, however, quite low as the condition of ballast cushion deteriorates very
fast. The reasons are:
•
perennial presence of water in the formation in most of the stretches
•
ingress of garbage thrown by nearby residents
•
trespass disturbing shoulder ballast, which affects packing under sleepers
Therefore it has been found very essential to continue through packing and
shallow screening in these sections to keep the ballast condition amenable to
machine tamping. While in other sections, machine maintenance eliminates
the need of through packing, this activity is to be continued in these
(suburban) sections.
5.4
CLASSIFICATION OF ACTIVITIES ON THE SUBURBAN SECTION
The subactivities of maintenance for the main line machine packed track have
been discussed in Chapter 3. Because of the peculiar features of suburban
section, the classification of subactivities has to be somewhat different for
74
(Vol.1)
suburban section. The following is the proposed classification of the activities
under the categories T, R and L.
5.4.1 Activities T (Affected by traffic density)
All the activities identified for machine packed non-suburban mainline will be
applicable for HD suburban mainline also.
5.4.2 Activities R (Routine activities – unaffected by traffic density)
On the Mumbai suburban section, tie tamping by machines does not yield the
desired retentivity of packing due to caked up ballast and limitation of lineblocks. Through packing continues to be an important activity for most of the
length. With progressive laying of concrete sleepers, increasing of ballast
cushion and introduction of LWRs, manual through packing may gradually
reduce in future.
The following subactivities are considered as Routine activities unaffected by
traffic density in addition to those identified for machine packed non-suburban
track:
•
Through packing:
This is continuing on the Mumbai suburban section, since deployment of
machines is not able to cope up with the disturbance to track due to
various reasons mentioned earlier. This subactivity is not treated as
influenced by traffic density, since the intention is to through pack entire
length of track once in a year.
•
Emergency attention:
Because of serious implication of any untoward incident, thereby affecting
the commuter traffic, it has been found necessary to keep skeleton staff for
round-the-clock attention to meet any emergency.
75
(Vol.1)
•
Extra assistance to Keyman and Blacksmith:
Due to very high frequency of trains, it is not possible for the
Blacksmith/Keyman to work independently. It has been the practice that
assistance of one additional gangman is given, on both Central and
Western Railways.
•
Extra lookout men to work with the gangs:
This is necessary to alert the gang in time whenever a train approaches,
due to the intensive frequency of train services, irrespective of the visibility
condition.
•
Extra work on account of night blocks:
Many works such as, casual renewal of rails, repair welding, tongue rail
and crossing renewals are done in night. Extra assistance is essential for
transportation and operation of generators and petromax lamps.
•
Extra assistance for S&T items:
It has been found necessary to provide assistance for S&T staff who are
attending to track bonds, S&T gears, insulated joints, switches etc.
•
Extra assistance for joint works with S & T and electrical branches:
Mumbai suburban sections have DC traction and traction bonds are
provided in all fish plated joints. Complete section being track circuited,
there are a very large number of glued joints. In all rail renewal works and
track circuit failure cases, the work has to be jointly done by P.Way, S&T
and Electrical staff. There is a substantial and essential additional
requirement of gangmen on this account.
5.4.3 Activities M (Miscellaneous)
Miscellaneous activities on suburban sections are the same as for nonsuburban sections.
5.4.4 Activities S (Site-specific)
Additional site-specific activity for suburban sections (Refer para 3.2.2.5) is
‘watching of water level and flood relief for train operation’. Mumbai suburban
76
(Vol.1)
section experiences very heavy rains and some stretches are prone to
sudden flooding due to factors external to Railways. The gangman deployed
for this watching duty has to stop the train in time in order to avoid serious
damage to the traction motors of trains due to heading of flood water above
rail level. He has to send message to organise dewatering in such areas and
removal of blockage in side drains.
5.5
CRITERIA FOR HIGH DENSITY SUBURBAN SECTION
It is proposed by the Committee, after considering the opinions of the Chief
Engineers of the zonal railways, that a suburban section can be regarded as
‘High Density Suburban Section’ only if both the following criteria are fulfilled:
(a)
The train frequency per hour, on any one line or in a sub-section,
should exceed 8 (eight).
(b)
The required maintenance works can be completed only by way of
availing night blocks.
The Chief Engineer (PHOD) will be competent to classify a suburban section
as ‘High Density Suburban Line’ based on the above criteria.
An example for the application of the above criteria is illustrated as follows:
On Western Railway, EMUs are running on Churchgate–Borivali-VirarDahanu Road section, which has been notified as suburban section.
However, only Churchgate-Borivali section qualifies as high density suburban
section. The headway between the trains in the morning peak, when the
movement is from suburbs towards Churchgate, is 3 to 4 minutes. The
morning peak is from 8.30 to 11.30 hrs. In the evening peak from 17.00 hrs,
reverse flow starts from Churchgate towards Borivali and the headway again
is 3-4 minutes. Productivity during these peak periods, particularly in morning
peak fully in gang duty hours, is extremely low. This section meets all the four
criteria for high density suburban section. Borivali-Virar and Virar-Dahanu
Road sections do not qualify as train frequency is less than 8 per hour.
77
(Vol.1)
5.6
MANDAYS REQUIREMENT
The methodology adopted for arriving at the mandays requirement for high
density suburban section is the same as that for non-suburban section.
The high density suburban sections of Sr.SE/Dadar of Western Railway and
Sr.SE/Byculla & Sr.SE/Thana of Central Railway were studied. When the
Committee called for the actual mandays utilisation on these sections, the
data were in different formats.
A proforma was therefore devised in
consultation with the concerned field Supervisors and Divisional Engineers for
recasting the data on a common base with due appreciation of the
subactivities which are unique to these sections as brought out by the field
engineers during the discussions.
It has been confirmed by the information collected, that the output per manday
for picking up slacks, through packing and shallow screening is less in these
sections. A comparison of the actual output with the norms recommended by
the Special Committee as well as by this Committee for non-suburban section
is tabulated as follows along with the norms now being recommended.

The information collected has been processed and actual mandays utilisation
per km of track has been computed for the activities T, R and L. Through
packing and picking up slacks cover the complete section in a year and
shallow screening covers one third of the section. The utilisation details have
been shown in Tables 17, 18 & 19.
78
(Vol.1)
For non-suburban section, mandays requirement per km was initially analysed
for plain track and thereafter it was stipulated that the requirement for turnout
should be calculated assuming equivalence of turnout in terms of plain track.
For high density suburban sections, the above approach has not been
considered appropriate, because the number of turnouts is disproportionately
large. Calculation of mandays requirement by considering equivalent track km
in lieu of turnouts will not be realistic, unless even in the initial analysis the
track km is considered duly taking the turnouts into account. Thus mandays
utilisation per km has been computed taking 10 turnouts = 1 track km in the
initial analysis itself.
Data for Sr.SE/Dadar, Byculla and Thana are given in Tables 17, 18 and 19
respectively.
Mandays utilisation per km for Activities T and R of these sections may be
compared, as a first step, with the requirement of non-suburban sections of
equal GMT and rainfall, ignoring the alignment and formation factors. The
comparison is shown as follows:

This comparison proves that the mandays requirement in high density
suburban sections is different from that in non-suburban sections.
In Table P3, all the data for the three sections have been abstracted for
comparison and also the suggestion for optimal utilisation of mandays has
been incorporated, adopting reasonable norms for the subactivities.
5.6.1 Mandays requirement for Activities T
It can be seen in Table P3 that 208 mandays for Activities T emerges as
suggestion for optimal utilisation in a section with 35 GMT, the most worked
section among the three sections studied. For non-suburban mainline, the
formula evolved is (80+2.3GMT)(1+A+B+C) for machine packed track and
(223+8.24GMT)(1+A+B+C) for manually packed track. It would be logical to
evolve a formula of the same pattern for suburban line also. The factor 2.3 or
8.24 is the gradient ‘mandays per GMT’. All the suburban sections will be
soon relaid with concrete sleepers and will be machine packed.
Therefore it
would be correct to adopt 2.3 as the gradient factor for the proposed formula.
208 mandays being the requirement for a section with 35 GMT, the formula
should be
208 = (K+2.3GMT)(1+A+B+C), where value of K is to be decided.
Applying values GMT=35, A=0, B=0, C=0.067
208 = [K+(2.3 x 35)] x 1.067, which gives the value K = 115
Hence, mandays/km/year for Activities T = (115+2.3GMT)(1+A+B+C)
5.6.2 Mandays requirement for Activities R
Referring Table P3, the mandays requirement for `Through packing’ and
`Shallow screening’ have been worked out on the basis of the recommended
norms (refer the table in para 5.6) and desirable quantum of work to be
executed per year.
It is clarified that ‘Nil’ mandays shown against any subactivity in Tables 17 to
20 does not mean that this subactivity is beyond the duties of gang. It is
80
(Vol.1)
simply the lack of data in required details due to which it is not possible to
assign mandays for each subactivity in each section.
By overall assessment, 398 mandays/km/year cover Activities R.
5.7
MANPOWER REQUIREMENT FOR MOBILE MECHANISED UNIT (MMU)
5.7.1 The MMU’s functions, equipment and vehicles for high density suburban
section will be similar to those for non-suburban sections explained in paras
4.11.1 to 4.11.4.
The equivalent MMU mandays can also be calculated
adopting similar procedure.
5.7.2 As stated in para 5.3.2, through packing the entire length of track once in a
year is a subactivity under Activity R in the case of high density suburban
section and it consumes substantial manpower as could be seen in Table P3
which gives the breakup for suggested optimal utilisation of manpower. Major
part of through packing can be carried out by MMU using off-track tampers.
Keeping this in mind the following subactivities and mandays thereof may be
assigned to the workload of MMU:
Activity T:
Slack attention
105 out of 128
Casual renewal of rails
10 out of 20
Casual renewal of sleepers
10 out of 20
Repair welding
10 out of 20
Total
Activity R:
Through packing
135
108 out of 184
Loading, leading & unloading
Total
12 out of 20
120
5.7.3 The suburban section dealt in Table P3 carries 35 GMT, calling for 208
mandays for Activity T as a whole, out of which 135 mandays correspond to
MMU workload and it amounts to 65% of 208. Therefore the expression for
81
(Vol.1)
MMU mandays is 0.65(115+2.3GMT) or (75+1.5GMT).
Thus for a given
length of LH (km) of highdensity suburban track, equivalent MMU mandays
=LH(75+1.5GMT)(1+A+B+C) + (LHx120)
In case running and non-running yard lines are available in high density
suburban section, these will be treated as non-suburban yard lines and the
formulae given in paras 4.7 and 4.8 will apply, since the constraints of
maintenance unique to mainline of suburban section do not exist for yard
lines.
The general expression for a P.Way subdivision/division having assorted
lengths of LH:
Gross Equivalent MMU mandays i.e. GEMM
= ΣLH(75+1.5GMT) (1+A+B+C) + 120 ΣLH
5.7.4 Strength and composition of MMU
Having computed GEMM, the strength and composition of MMU are decided
applying the same principle explained in paras 4.11.9 to 4.11.11, namely,
80% of annual emoluments of GEMM = Annualised cost of SEMMU +
Annual emoluments of MMU staff.
5.7.5 The Committee recommend that the Chief Engineer can decide GEMM with
flexibility, as in the case of non-suburban mainline as explained in para
4.11.11. The apportioning of mandays to MMU workload, indicated in para
5.7.2, can be changed by the Chief Engineer depending on local conditions
and efficiency of MMU in high density suburban sections.

The Chief Engineer can vary the value of GEMM, depending on the local

materials.
The cadre structure of Gangmen and pay scales thereof, as
stipulated by the Railway Board should be taken into account and Leave
Reserve of 12.5% should be allowed, while computing the annual
emoluments of GEMM. The cadre structure and pay scales should be taken
into account and Travelling Allowance payable should be allowed, while
computing the annual emoluments of MMU.

6.1
EVOLVING OF NORMS FOR ACTIVITIES M AND S
Subactivities under Activities M and S have been listed in para 3.3.3.2 and
3.3.3.3. Mandays requirement for Activities T and R is based on continuous
length of track, whereas that for Activities M and S is, by and large, not based
on continuous length, but depends mainly on the localised problems, special
features and geographical nature of the P.Way section. The requirements
should therefore be assessed very judiciously. Authorisation is essential for
the factors influencing some of the subactivities so that the computations are
based on proper norms and factual position. The following authorities are
recommended for certifying the correctness of the factors:
•
No. of days for monsoon patrolling - CTE/CBE
•
Need for hot weather and cold weather patrolling - CTE
•
No. of days for watching vulnerable locations - CTE/CBE
•
Need for Store watchman duty (upto 2 locations) - Sr. DEN/Co-ord.
•
Existence of extremely bad formation – CTE
•
Identification of track stretches with poor visibility – Sr.DEN/Co-ord.
•
Need for Fog signal man duty - Sr. DEN/Co-ord.
•
Need for removal of filth from track - Sr. DEN/Co-ord.
•
Need for security patrolling – Sr.DEN/Co-ord.
•
No. of days for watching water level in suburban section - Sr.DEN/Co-ord.
The computation of mandays for Activities M and S should be done for the
jurisdiction of a Senior Section Engineer. In the following paras 6.2 and 6.3,
principles underlying the calculation of mandays requirement for various
subactivities have been briefly explained. The same have been more
precisely expressed in the form of formulae in the concluding para 6.4.
6.2
MAN-POWER NORMS FOR ACTIVITIES M (MISCELLANEOUS)
6.2.1 Monsoon patrolling
Monsoon patrolling is carried out to give protection to trains against flood
calamities.
The number of patrol-beats in each beat-length (based on
84
(Vol.1)
overlapping or non-overlapping beats), number of shifts in each beat-length
and the number of patrolmen required are clearly worked out in the patrol
charts. Night patrol is prescribed only for a specific period in each section.
Mandays required per year = Total No. of patrolmen engaged in 24 hours x D
where D = No. of days for which patrolling is required.
6.2.2 Hot weather patrolling of LWR track
This is required to be carried out during hot part of the day in summer season,
duly following the provisions in LWR manual. In zones of less temperature
variation and in the case of track structure with adequate lateral strength, hot
weather patrolling can be dispensed with, as decided by CTE.
Mandays required per year = 30 x length of LWR track in km, on single line
basis.
6.2.3 Cold weather patrolling LWR track
This is required to be carried out during very cold hours in winter season, if
the track has the past history of incidence of rail fractures.
CTE should
authorise the need for this activity.
Mandays required per year = 12 x length of LWR track in km, on single line
basis.
6.2.4 Watching vulnerable locations
There are identified vulnerable locations and these are also indicated in the
patrol charts. The number of stationary watchmen posted at various locations
and their shift-details are indicated in the patrol charts on many Railways.
Mandays required per year = (S x d)
where, S = Total No. of stationary watchmen engaged in 24 hours
d = No. of days for which the locations are watched.
85
(Vol.1)
6.2.5 Gate keeping at Engineering Level Crossings
On most of the Railways, Gatekeeper posts and Leave Reserve posts for the
same are sanctioned separately and these do not form part of the gang
strength. However Rest Givers are drawn from sectional gangs.
Mandays required per year = 365 x (No. of LCs x No. of shifts) - M
where, M = Mandays available due to regular sanctioned Gatekeepers
(excluding Leave Reserve Gatekeepers).
The ultimate aim should be to create adequate posts of GKs, so that both LR
and RG can be met 100% utilising this cadre.
6.2.6 Rest giving for Keymen
Each keyman works for 290 days in a year, whereas keyman patrolling has to
be performed for 365 days. Therefore 365-290 = 75 mandays have to be
drawn from the gangstrength against each beat of keyman.
Hence the
manpower requirement for each Sr.SE will be as follows:
Mandays required per year = No. of keyman-beats x (365-290).
6.2.7 Waterman duty
The waterman to be provided will be one for each gang. Hence the mandays
required per year for each Sr.SE = No. of gangs x 290
6.2.8 Store watchman duty
The stores khalasis and watchmen for the store at Sr.SE’s headquarters are
separately sanctioned.
The need for additional men arises due to the
materials being kept at other locations. The committee is of the view that
86
(Vol.1)
materials should normally be kept at not more than 2 places in a Sr.SE’s
jurisdiction and requirement on this account can be worked out on the basis of
three watchmen on 8 hours duty at each location.
Mandays required per year = No. of stores location x 3 x 365
Where materials of track renewal works are lying, separate provision in these
estimates should be made.
6.3
MANPOWER NORMS FOR ACTIVITES S (SITE SPECIFIC)
6.3.1 Tunnel maintenance
Tunnel inspection and maintenance needs some mandays which necessarily
get drawn from sectional gangs. The activities involved are extra track work
at the time of dropping of boulders and cleaning of drains. Lookout men and
persons for lighting are also required while carrying out inspections and track
maintenance works.
The Committee for “Rationalisation of costing Permanent Way activities”, in
para 4.9 of their report, recommended a BMKM factor of 1.2 for tunnels. This
factor has the material and manpower cost. Since manpower is the major
component, the factor of 1.2 is directly applicable to manpower. The
committee recommends the same factor for manpower calculation.
Mandays required per year
= Σ (Length of tunnel in km x No. of lines in the tunnel) x 1.2 x 290
6.3.2 Bridge substructure maintenance
On some Railways, mandays from gangs are utilised for the maintenance of
bridge substructures. Such works are maintenance of inspection steps,
grouting masonry, assisting mason at the time of repair works and minor
attention to protection works.
87
(Vol.1)
The Committee for “Rationalisation of costing Permanent Way activities”
recommended a BMKM factor of 1.2 for girder bridges and 1.1 for other
bridges. The total maintenance input can be taken as 1.1 man per km of
lineal waterway. This has to be enhanced for multiple lines, with ROBs and
RUBs also included.
Mandays required per year
= Σ (Length of Bridge in km x No. of lines on the bridge) x 1.1 x 290
6.3.3 Long girder bridge maintenance
Extra requirement for this subactivity should be assessed only for bridges,
each having a lineal water way of 150m or more. The extra maintenance on
these bridges will consist of maintaining trolley refuges, attention to guard
rails, pulling back creep on approaches, extra efforts for replacement of
sleepers, etc. It would be sufficient if a team of 6 gangmen are drafted to
attend to these activities 4 times a year, each time for 4 days, for a bridge of
150m waterway.
Mandays required/yr = 6x4x4 x Total lineal water way of such bridges (in m)
150
= 0.64 x Total lineal water way of such bridges (in m)
6.3.4 Extra workload due to very sharp curve, deep cutting and steep grade
Extra mandays required for all curves sharper than 1o on BG and 2o on MG
will get computed by considering Alignment Factor vide para 4.6.2. However,
o
o
for curves sharper than 3 on BG and 6 on MG, even more frequent attention
is required for greasing of rails, correcting alignment, regauging, attention to
check rails and turning of rails. It is necessary to provide one additional man
for every 1 km of such very sharp curves, along with which deep cuttings and
steep grades will invariably co-exist, warranting extra maintenance efforts.
o
Mandays required (BG) = Length of track (in km) sharper than 3 x 1 x 290.
o
Mandays required (MG) = Length of track (in km) sharper than 6 x 1 x 290.
(Corresponding provision for NG is not considered necessary.)
88
(Vol.1)
6.3.5 Maintenance of track on extremely bad formation
Formation Factor (Refer para 4.6.1) will take into account manpower
requirement upto 20% extra for bad spots.
In actual practice this is not
adequate for track on extremely bad formation requiring attention to alignment
and cross levels almost once in 3 months. At each such location a gang of 10
men may have to be deployed four times a year for 3 days on a length of
200m for attention.
Mandays required per year=
[Length (in m) requiring atleast 4 attentions per year x 10 x 4 x 3]/200
It is needless to emphasise that permanent remedial measures should be
carried out on priority to eliminate extremely bad formations.
6.3.6 Look out man duty
Depending upon the locations and lengths of curves/cuttings with poor
visibility, additional look out men are required to work with gangs.
Such
stretches should be identified by Sr.SE, verified by AEN and certified by
Sr.DEN/Co-ord. The mandays requirement for each ganglength will be
Length of track with poor visibility x 290
Length of ganglength
For the section of Sr.SE, mandays for all gangs are summed up.
6.3.7 Fog signal man duty
Deployment of gangmen as fog signal men to assist station masters is a
regular feature in winter. The mandays of gangmen thus lost have to be
recouped, which can be assessed based on actual mandays utilised for this
activity for a year, taking the average of three immediately preceding years.
Mandays required =1/3 x Total mandays actually utilised in last three years
89
(Vol.1)
6.3.8
Filth removal from track
This requirement arises generally for ganglengths in the vicinity of big cities
and should therefore be based on actual field experience. Provision of one
man per gang should be adequate to look after this work.
Mandays required per year = No. of gangs functioning in such areas x 290.
6.3.9 Security patrolling
Security patrolling is ordered to ensure safety against tampering of track and
bridges by miscreants. In some disturbed areas such patrolling continues
over long durations in a year, thereby adversely affecting mandays available
for track maintenance. Though such patrolling should be assigned to security
forces, it is the general practice to deploy gangmen, who are readily available
at short notice and who know how to protect the track. Hence there is need
for recouping the mandays lost.
Mandays required = 1/3 x Total mandays actually utilised in last three years
6.3.10 Watching of water levels in suburban sections
This activity applies to suburban sections with high probability of flooding of
tracks. The importance of this function has been brought out in para 5.4.4.
There are nominated locations where water level has to be watched
continuously during monsoon season.
This is generally required for two
months of intensive rain and staff have to be deployed round the clock.
Mandays required per year = No. of locations x 2 x 60
It is assumed that in the monsoon period of 4 months, the intensive rain
period will be about 60 days.
90
(Vol.1)
6.4
ANNUAL REVIEW OF MANPOWER REQUIREMENT FOR ACTIVITIES M & S
Whenever annual review of gangstrength for Activities T and R is undertaken,
it is necessary to reassess the manpower requirement for Activities M and S.
This is because, developments are effected from time to time, which change
the Activities M and S, such as:
•
Number of monsoon patrol beats adjusted as per changed train service.
•
Vulnerable locations eliminated due to works carried out.
•
Level Crossing replaced by ROB/RUB.
•
Jurisdictions of ganglengths reorganised.
•
Number of stores depots reduced.
•
Construction of bridges with ballasted deck or ballastless track in lieu of
long girder bridges.
•
Boundary walls constructed to prevent trespass into track.
•
Soil stabilisation work carried out.
•
Letting out some works on contract.

EQUATED MANPOWER KILOMETRE,
THE RECOMMENDED PERFORMANCE UNIT
7.1
At present ‘Equated Track Kilometre’ is used as the performance unit for
matching the manpower or the expenditure, against the revenue activity of
track maintenance. In the pre-modernisation era, ETKM would have served
this purpose with fair accuracy, since all the three factors, namely, manpower,
maintenance cost and ETKM were defined to be proportional to each other.
As track modernisation was spreading over a part of the system, the
manpower/ETKM was reduced as per the correction factor K (in Special
Committee Formula) for the modernised length of the track, whereas the
corresponding ETKM remained unchanged. Thus the linearity between gross
ETKM and gross manpower got vitiated. By referring the contents of paras
2.9.3 and 2.9.4, it can be appreciated that ETKM has lost its relevance as the
performance unit, which is also corroborated by the factual position tabulated
in Appendix 2.
7.2
In the absence of a reliable performance unit, it will be impossible to
rationalise manpower among zonal railways and other lower units,
proportional to the effort of track maintenance required.
Therefore the
Committee have proposed a new performance unit, ‘Equated Manpower
Kilometre’ (EMKM). This is in modification to the concept of EMKM defined in
the Report of the Committee for Rationalisation of Costing Permanentway
Activities. (Dec.95).
7.3
CONCEPT OF COMPARATOR TRACK
7.3.1 Applying Special Committee formula ETKM = UL(1+A+B+C) to a track
carrying 2.5 GMT/annum, laid on trouble free formation in low rainfall area
with fairly straight alignment, i.e. U=1, A=0, B=0 and C=0,
ETKM of 1 km track = 1 unit
94
(Vol.1)
7.3.2 In other words, the track of the above said description can be regarded as
‘comparator track’ to gauge the maintenance work load arising in any other
track. For example, if there is a track of length L, whose ETKM = 1.5L, it can
be visualised that the maintenance workload for this track is 1.5 times that of
comparator track, for which U=1, A=0, B=0 and C=0.
7.3.3 Another analogy can also be presented. If there is a metal whose density is
2.6 gm/cc (or specific gravity 2.6), anybody will understand that this metal
possesses 2.6 times the heaviness of water. Here water is the comparator.
7.3.4 Therefore the Committee decided to define, in the environment of the Rational
Formulae, a comparator track which will have moderate characteristics
requiring moderate level of manpower. Such a track can be easily visualised
by any track engineer, so that he can judge the manpower requirement of any
other track as a multiple/fraction of that for the comparator track.
7.3.5 It should be remembered that Special Committee formula is meant to give
manpower requirement per km for certain salient activities of track
maintenance and this formula does not take into account many other
activities, which have been identified mostly under Activities M and S in this
report. Manpower requirement for many subactivities under M and S is not on
“per km” basis; but is assessed for the P.Way section as a whole. Therefore
in the environment of the Rational Formulae, “one km of comparator track”:
should be considered as the “averaged one km of the comparator P.Way
section”, if the manpower requirement for all Activities T,R, M & S has to be
covered under this concept.
In fact only by resorting to this concept, the
performance unit will achieve perfection, by covering the manpower required
for all the activities.
7.4
Thus as the first step to define MCNTM comparator track, a comparator
P.Way section has to be defined. Suppose the physical length of mainline
track is L in the comparator section, there will be additional lengths of track in
running and non-running yard lines and equivalent lengths of turnout. After
assessing total mandays requirement for all Activities T, R, M & S, the same
95
(Vol.1)
will be divided by L only (i.e. ignoring the other lengths of track) to find out the
mandays requirement/km as an average over the section.
Now, the no. of gangmen required per km for a typical P.Way section serving
as comparator, is calculated as follows, assuming parameters which
necessitate moderate manpower:

Mandays requirement
= 6346+(11766+5049)+1200+840+336+750+2900+242
= 29429
Mandays requirement including LR = 1.125 x 29429 = 33108
Mandays required for LR for 10 gangmates and 10 keymen =
0.125 x 20 x 290 = 725
Total mandays requirement = 33108 + 725 = 33833
No. of gangmen required per km = 33833/(290x70) = 1.6667 = 12/3
7.5
It would be seen that the MCNTM comparator track is assumed to carry
2.5GMT/annum, corresponding to U=1 in the Special Committee Formula for
ETKM. The comparator track, which is of BG, will be the same irrespective of
97
(Vol.1)
the track being compared is BG, MG or NG. This rectifies the mistake in the
ETKM concept, pointed out in para 2.9.3.1.
7.6
UTILITY OF EMKM
Having arrived at the gangstrength of 12/3 per km for MCNTM comparator
track, this becomes the basic unit for 1 EMKM. Suppose a P.Way section of
80km length (mainline track only) requires 240 men as per Rational Formulae,
EMKM for the section = 240/12/3 = 144
EMKM of each km of the section = (240/80)/ 12/3 = 1.8
The corresponding visualisations are:
•
The section is deemed to contain 144km of MCNTM comparator track,
considering total manpower requirement.
•
Per km requirement of manpower is 1.8 times that for MCNTM comparator
track.
7.7
DEFINITION OF EMKM
EMKM of a P.Way section = 0.6 (Total gangstrength required as per Rational
Formulae)
EMKM of 1 km of track = 0.6 (Gangmen per km as per Rational Formulae,
considering P.Way section as a whole)
7.8
Appendix 2 shows that the number of trackmen per ETKM is 1.72 for the
whole of Indian Railways and it varies from 1.36 to 2.12 on zonal railways.
Seeing the norm of 12/3 men per EMKM, it will be difficult for anybody to guess
whether the total gangstrength will increase or decrease on account of the
implementation of the Rational Formulae. It has to be realised that EMKM will
not be equal to ETKM and therefore no. of men per ETKM is not comparable
with no. of men per EMKM. The repercussion of implementing the Rational
98
(Vol.1)
Formulae has been studied in depth over five units on Central, Northern and
Western Railways and this will be discussed in Chapter 9.
7.9
FUNCTIONALITY OF EMKM AS PERFORMANCE UNIT
7.9.1 Let us assume that L is the physical length of a P.Way section (i.e. total length
of all mainline tracks). Gangstrength requirement for this section is calculated
using the Rational Formulae and is divided by 12/3 to yield EMKM of the
section LE.
The factor LE/L denotes EMKM of each km of the section and will be useful for
comparison of manpower concentration among P.Way sections.
Over a division or zonal railway, EMKM of the unit = ΣLE. If the sanctioned
gangstrength for the unit is more than 12/3ΣLE, it indicates surplus staff; if it is
considerably less than 12/3ΣLE, it indicates deficiency of manpower. In other
words, every unit must aim to achieve the status of “Sanctioned
Gangstrength/EMKM=12/3”, if MMUs are not formed out of gangstrength. If
however MMUs are formed, “Sanctioned strength/EMKM” should be
somewhat less than 12/3.
Thus EMKM is an effective performance unit, enabling at-a-glance evaluation
of manpower deployment.
7.9.2 The norm of 1.47 men/ETKM on BG and 1.21 men/ETKM on MG/NG as per
Special Committee formula did not take into account manpower requirement
for a large number of activities. It excluded leave reserve. Therefore actual
number of men per ETKM was varying from section to section and many
excuses could be put forth qualitatively to explain the variation in each
section.
But in the environment of the Rational Formulae, the manpower
factor of 12/3 men/EMKM is the same for any section on BG, MG or NG; it
includes all the activities; it covers mechanical or manual mode of
maintenance; it applies to non-suburban and suburban lines; it embodies
leave reserve also.
99
(Vol.1)
7.9.3 Thus the Committee recommends that the performance unit for the purpose of
staff strength evaluation should be EMKM, which is defined as numerically
equal to 0.6 times the number of gangmen required as per the Rational
Formulae.
7.9.4 For carrying out manpower analysis, only gangstrength and MMU staff should
be considered against EMKM, after duly separating the posts of Gangmates,
Keymen, Artisans, Trolleymen, Watchmen, on-track machine staff etc.
mentioned in para 4.10.1.
The tabulations in the book of Demands and
Grants should be modified accordingly.
7.9.5 The application software MANPOWER evolved by the Committee does not
incorporate EMKM.
After the Railway Board approves this concept,
IRICEN/Pune may modify the software.
7.10
Similar to EMKM, it is possible to evolve Equivalent Cost Kilometre (ECKM)
as the performance unit for comparing maintenance cost per km among
various units and for distributing funds judiciously. This concept is already
contained in the Report of CRCPA (Dec.95). The evolving of ECKM, in the
environment of Rational Formulae, may be included in ‘Part 2: Cost-Norms’ of
the Report to be compiled by the new members of the MCNTM Committee, to
be nominated by the Railway Board, as mentioned in para 1.6.
100
(Vol.1)
8.
RECOMMENDATION ON THE OTHER TERMS OF REFERENCE
AND THE ISSUES RAISED BY FIELD ENGINEERS, NFIR AND AIRF
8.1
The original terms of reference assigned to the Committee vide Railway
Board’s letter No.95/CE-I/GNS/2 dt.05.01.96 (Annexure A) is reproduced
below:
“i)
To study the Special Committee Formula for Gangstrength and to
suggest modified formula covering certain variables left out in the
existing Special Commiittee Formula which affect track maintenance
effort.
ii)
The Committee shall take into account the decasualisation done, effect
of machine maintenance and track modernisation”.
It would be seen that the Rational Formulae evolved in Chapters 4, 5 and 6
have exhaustively dealt with all the limbs of the terms of reference except the
aspect of ‘decasualisation’.
Decasualisation was carried out mainly for regularising the casual labourers,
who attained temporary status and continued to be under the same service
conditions for prolonged periods. These labourers were originally recruited to
perform such of the duties not covered under Special Committee Formula,
listed in para 3.3 of Appendix 1. Now that the Rational Formulae cover all the
subactivities of maintenance, except those which can be let out on contract,
the revised gangstrength will enable conversion of many of the decasualised
posts into regular posts.
If the revised gangstrength leaves part of the
decasualised posts uncovered, such posts should be declared surplus
immediately. As per the well established rules, the following methods can be
resorted to:
•
Optees to other departments/other units can be transferred. The resultant
vacant posts will enable surrender of corresponding numbers of
supernumerary posts.
101
(Vol.1)
•
The incumbents of surplus posts can be transferred to the vacant posts
arising in such of the units, where the revised gangstrength is more than
the existing sanctioned regular gangmen posts plus existing decasualised
posts. Monetary grants or certain other concessions can be offered to
encourage such transfers.
•
Retirement wastage can be allowed to take place, particularly if the
incumbent has less than 3 years of residual service.
•
Taking recognised trade unions into confidence, transfers can be
implemented compulsorily.
In any case, during the above exercise, no additional posts should be created
in any unit in anticipation of wastage/surrender expected to take place in other
units.
8.2
As regards appointment of safaiwalas as part of gangstrength for cleaning the
track passing through densely populated area (Annexure F), the Rational
Formulae for Activities M provides for the posts required for this purpose. If
some of the gangmen are willing to carry out this duty, even if it may involve
transfer, such staff can be encouraged. Otherwise these posts can be filled
up by drawing safaiwalas from Medical department, who will however work
under the day-to-day control of P.Way supervisor. Since such locations are
situated in important cities, it is quite likely that safaiwalas of Medical
department working in far-off places may readily opt to accept deputation to
Engineering department.
However such staff will revert back to parent
department, when due for promotion.
8.3
The issue of deputing gangmen for monsoon patrolling (Annexure G) is
considered very important from safety and morale points of view.
Perhaps the alternative to deputing gangmen is the letting out of this work on
contract.
The P.Way mate or supervisor can and should order starting of patrolling, the
moment he sees indication of isolated thunder storm or starting of monsoon
102
(Vol.1)
before the nominated date. Depending on the number of beats and shifts in
each beat-length, substantial number of men have to be thrust into service.
Contractor’s men will not be available all of a sudden.
Further the duty of patrolman is much more than merely walking and watching
the track.
He must know the characteristics of floodwater, with particular
reference to the local geographical features. He should be able to apprehend
disaster when he sees relevant symptoms.
If he is knowledgeable and
confident, he can distinguish such of the flood events which may not affect the
track or formation, thereby avoiding false alarm. On the other hand, if he
exercises correct judgement, he will alert all the staff concerned well in
advance before a disaster takes place. Many gangmen, though illiterate, do
possess extraordinary instinct to anticipate flood problems, displacement of
boulders in the cuttings, sinking of formation, land slips, land slides of
mammoth size, etc.
By performing the patrol duty, the gangman acquires a sense of belonging to
the track and he gets sentimentally attached to the section and its safety.
Further, walking over long distances keeps his physique more fit. He gets
weather beaten and becomes robust to perform normal duties also.
On many occasions, gangman on monsoon patrol duty is able to rectify minor
flood damages by himself immediately, which curbs further damage and
eliminates even major washaway.
Some gangmen on monsoon patrol duty take correct decision to permit trains
at restricted speed, instead of stopping the service. His technical knowledge
gives him the confidence.
Due to above said reasons, monsoon patrol should continue to be performed
by gangmen. The Rational Formulae provides for mandays for this purpose
under Activity M.
103
(Vol.1)
8.4
A question has been raised as to whether gangmen posts should be created
to perform security patrol. (Annexure I). Many times the need for security
patrol arises all of a sudden based on message flashed by civil authorities.
Gangmen are available throughout the section at all times. There is no option
but to send them on security patrol, because RPF jawans are neither
available in adequate numbers, nor can they spread out at short notice. The
Rational Formulae provides for mandays for this purpose under Activity M.
8.5
The next issue to be tackled is, how to consider the age factor of gangmen
and modify the norm of output depending on the fitness of the individual
gangman.
8.5.1 The Committee strongly feels that it is not the age, but the physical fitness to
work should be the factor to be considered. During interaction, many field
engineers expressed concern over the fact that the medical category B-1
prescribed for gangman has nothing to do with stamina aspect.
8.5.2 The Rational Formulae have been evolved, based on average productivity of
individual gangman. It is necessary to ensure overall productivity by weeding
out weak persons.
8.5.3 The Committee noticed that on some of the railways, at the time of initial
recruitment or regularising the service, the labourer is asked to run for 200m
carrying a cement bag of 50kg.
By issue of regular order, ‘Physical
Endurance Test’ (PET) should be standardised as done in the Army. Such a
test should be conducted through a Committee of doctors at the time of
recruitment to gangman cadre and at the time of periodical medical
examination of gangmen. The parameters of health condition such as X-ray
report, blood pressure test, blood and urine tests, etc should also be kept on
record. Any gangman failing in PET should be medically decategorised and
removed from the cadre.

8.5.4 If the performance of a gangman is found to be poor attributable to his
physique as reported by the supervisor, he should be sent for PET,
irrespective of whether he is due for PME or not.
8.5.5 These recommendations reflect the views of field engineers who expressed
anguish regarding the diminishing stamina of gangstaff.
8.5.6 The Committee is of the opinion that whereas the nature of gangman’s work is
strenuous and he is exposed to adverse weather conditions, the same factors
can lead to better physique and healthier life, if the gangman takes care of his
habits. In army, it is the duty of everybody to keep his health proper. Though
the rules are different between civil and military careers, it is not impossible to
device methods of counselling and training schemes for gangmen, so that
they realise that it is their duty to maintain their stamina. The Committee
members, who have put in nearly 35 years service, have really seen that
gangmen were robust even after the age of 50 years, in 1960’s and 70’s. The
Committee recommend that some senior officers of Medical department may
be detailed to examine this aspect and to come up with suggestions on how to
improve the general health of gangmen by various means.
As a part of
training courses and also in the field, yoga should be taught to gangmen and
schemes should be drawn for implementing both kinds of lessons.
8.6
The problem related to that dealt in para 8.5, is the rampant absenteeism
among gangmen.
As stated by many field engineers, all gangmen avail
casual leave and LAP to the maximum limits. Many gangmen are not even
bothered about loss of pay due to LWP/absence. This has been pointed out
by NFIR and AIRF, who have suggested that leave reserve be increased to
30%.
The field engineers are concerned about the loss of mandays on
account of absenteeism, which is not recouped due to ban on recruitment of
casual labour.
105
(Vol.1)
The Committee is of the opinion that increasing of LR more than 12½% will
further encourage absenteeism.
Instead, constructive methods should be
devised as mentioned in 8.5.6.
In fact absenteeism is not necessarily on
account of health reason. A drive should be undertaken to initiate disciplinary
action and to remove the frequent absentees from service.
This is the
responsibility of Divisional Railway Managers.
Drastic steps should be taken, as suggested by Honourable Justice Shri N.
Venkatachelliah in the course of judicial enquiry into a railway accident, such
as, condonation of maximum two day’s unauthorised absence in a month and
treating unauthorised absence for over 24 days in a year as misconduct
leading to removal from service.
There was some suggestion that during annual review of gangstrength, extra
gangmen posts may be created based on the mandays lost (without payment
of salaries) in the past year. This will go against the principles of manpower
planning and this evil may spread to other departments if initiated in
Engineering department.
However, realising the adverse effect of mandays lost on maintenance, the
Committee recommend that Chief Engineer should collect information on
money saved every month (with finance concurrence), preferably through
computer networking, and release this money for operating contracts to clear
the arrears of work.
Railway Board may authorise this procedure and
delegate the powers to the Chief Engineer for reappropriation of funds from
PU-01 to PU-32.
But the Finance Member of the Committee does not concur this
recommendation, pointing out that this will encourage absenteeism and the
method of compiling information on monthly savings due to absenteeism will
be cumbersome. The Technical Members are of the opinion that, whereas
every effort should be taken to curb absenteeism, maintenance activities
should not be allowed to suffer due to shortage of input of mandays, in the
interest of safety and realisation of full life span of track.
106
(Vol.1)
8.7
Many
field
engineers
expressed
that
gangwomen
appointed
on
compassionate grounds are not able to work hard. Considering the nature of
duties of gangwork, a woman is seriously handicapped during monthly cycle.
Her personal safety is also not quite satisfactory under the real environment,
sometimes being called to work in nights if there is emergency.
While
ensuring that women are not discriminated, it should also be realised that they
should not be subjected to hazardous situations. The Committee recommend
that Sr.DEN/Cordination should decide the total no. of gangwomen that can
be accommodated, identifying the nature and quantum of job that can be
performed by them. He will advise this to the Chief Engineer along with the
Annual Review of gangstrength.
The Divisional Railway Manager should
ensure that this limit is never exceeded while appointing women in the gangs.
The instructions contained in Railway Board’s letter No.E(NG)-II/97/RC-1/117
dt.21.10.97 should be strictly followed.
8.8
Some field engineers expressed opinion that the age of the track should be
taken into consideration in gangstrength formula.
The Committee has
formulated the norms based on data collected from various sections, each
containing tracks of varying ages. Therefore the norms correspond to the
requirements for track of average age.
While keeping the overall
gangstrength of P.Way section as calculated, readjustment of strengths of
various gangs in accordance with the age profile of stretches of tracks can be
carried out and such a proposal can be approved by the Divisional Engineer.
8.9
Some field engineers, NFIR and AIRF have suggested for creation of trainee
reserve posts for gangman cadre. Gangman being safety cadre spanning
over Group C and Group D, the technical members of the Committee feel that
this is a good suggestion and trainee reserve of 2% should be just optimal.
Training centres for gangmen should be strengthened, so that they acquire
the skill to maintain track in a professional manner and to utilise the small
track machines effectively.
However the Finance Member does not concur creation of 2% Trainee
Reserve posts and opines that this must be managed within the Leave
107
(Vol.1)
Reserve provision. The Technical Members are of the opinion that Leave
Reserve is meant for its own purpose and that with the emphasis being given
to impart adequate training to staff belonging to safety category, (Para 5 of
Summary of Recommendations in Part I of ‘Report of the Railway Safety
Review Committee, 1998’), this issue deserves Board’s consideration.
8.10
The last issue dealt is the identification of activities of track maintenance that
can be let out on contract (Annexures K, L and M). After studying the existing
practices on the zonal railways, Konkan Railway and after reviewing the
extant instructions from legal point of view, the Committee recommends that
the following activities can be executed through contract system:

PILOT STUDY CONDUCTED ON THREE DIVISIONS OF
NORTHERN AND WESTERN RAILWAYS (NON-SUBURBAN) AND
ON TWO SUBDIVISIONS OF CENTRAL AND WESTERN RAILWAYS
(HIGH DENSITY SUBURBAN), APPLYING THE RATIONAL FORMULAE
9.1
Engineering Department performs ‘Way’ and ‘Works’ functions. The ‘Way’
function, namely, track maintenance forms the major activity on Indian
Railways, engaging a work force of 2,46,379 staff (1998-99 figure), counting
only the non-supervisory Group C and Group D categories, excluding
supervisory Group C and Officers. The trackmen of this work force constitute
a major component of the total number of employees, which is 15,83,600 on
Indian Railways.
This component is entirely governed by the gangstrength norms prescribed.
Any change implemented in the norms may have significant effect on the
number of staff with corresponding financial implication.
Therefore the
Committee decided that the Rational Formulae should be applied, as a
theoretical exercise, but with all precision, taking permanent way staff of some
divisions. Initially this pilot study was proposed for Ambala Division of N.Rly
and Ratlam Division of W.Rly, subsequently extended to Allahabad Division of
N.Rly also, as regards non-suburban lines. For high density suburban lines,
Sub-divisions Mumbai Chatrapati Shivaji Terminus of C.Rly and Mumbai
Central of W.Rly were selected for the pilot study.
9.2
The application of Rational Formulae calls for collection of lot of additional
field data on track, over and above what is required for Special Committee
Formula.
It was realised that the concerned Divisional Engineers should
appreciate the importance of each data collected and its correct application in
the formulae. Therefore the pilot study necessitated detailed briefing for the
officers and field engineers involved, to make them understand the formulae
entirely.
109
(Vol.1)
9.3
Due to the multiplicity of calculation steps handling large amount of input data,
especially for Activities M and S, need was felt for the evolving of application
software.
The Committee decided that the software be developed and
perfected for the pilot study itself, so that the same can be widely adopted all
over the Indian Railways, after the Report is accepted by the Railway Board.
Chief Engineer/W.Rly, the Committee Member, organised the development of
software through the Engineering Computer Centre.
Pilot study was very
useful in locating bugs in the program and eliminating them.
9.4
The documentation on the Application Software MANPOWER may be seen in
Appendix 7.
A typical calculation of gangstrength for a P.Way section by
applying the Rational Formulae has been given in Appendix 8.

E–B
In four out of the five cases above, excess posts have been identified.
However the abnormal numbers of excess and shortfall in manpower deserve
explanation.
9.6.1 Allahabad Division covers the first Rajdhani route between Delhi and Calcutta.
In early 70’s when RDSO conducted high speed trials on this division, there
110
(Vol.1)
was a need to explore how best the track geometry can be achieved and
sustained, with CST-9 sleepers extensively present in the track of those days.
Moreover Northern Railway administration tried laying of LWRs on continuous
lengths on Allahabad Division. Many other works were undertaken to improve
the track, with the intention to achieve safety of the highest order, when the
traditional speed barrier of 100 km/h had to be broken. Due to these reasons,
casual labourers were liberally engaged, in the absence of any ban on such
recruitment. Subsequently decasualisation covered the huge work force of
2467 men as seen in the Table under para 9.5. This explains the reason for
the excess posts of abnormal number.
9.6.2 In Ambala Division, there is a considerable shortfall of 626 men. This should
be considered as a rare instance, due to the factors given as follows:
•
Ambala Division was carved out of sections of Delhi and Ferozpur
Divisions and came into existence on 01.07.1987. When the Division was
bifurcated, many gangmen left for other divisions. Posts were not created
according to Special Committee Formula, due to the emphasis given on
manpower control.
Against 2488 posts that could be justified as per
Special Committee Formula, only 2046 regular posts of gangmen exist.
•
Due to law and order problem, 203 gangmen are deployed for security
patrolling and these posts were not created. Due to application of Rational
Formulae providing manpower for this function, the shortage has surfaced.
•
Likewise 73 gangmen are deployed for fog signalling and this shortfall has
also become visible.
•
Lot of arrears of track maintenance works have accumulated and it is
stated by the Sr.Divisional Engineer/Coordination that this will have
adverse effect on the service life of track structure.
9.6.3 Chief Engineer/N.Rly, who is a Committee Member confirms the contents of
paras 9.6.1 and 9.6.2.
9.7
If this pilot study is considered as a typical sample survey covering varieties of
situations, it is seen that there may be scope for reduction in manpower to the
111
(Vol.1)
extent of 12.24%. But the Committee clarifies that this figure of 12.24% need
not be a realistic or reliable representation of the overall situation, since the
size of the sample, namely 16,324 is very small compared to the total gang
strength of 2,46,379 on Indian Railways.
9.8
The activities to be performed by permanent gangs as per Special Committee
Formula are more or less the same as Activities T and R in the Rational
Formulae.
Therefore it would be of interest to compare the number of
gangmen calculated for Activities T and R only to the regular sanctioned
strength which is expected to be the gangstrength as per Special Committee
Formula. This comparison may be seen in the following table:

# This figure would have been 1477, had Ambala Division created 2488 posts.

112
(Vol.1)
Thus it is seen that the Rational Formulae help in better optimisation of
manpower as compared to Special Committee Formula, when like activities in
both cases are considered.
9.9
In the Pilot Study, application of the Rational Formulae has clearly exposed
the abnormal situation of manpower issues pertaining to Allahabad and
Ambala Divisions.
9.10
In view of the results anticipated as explained in paras 9.7 and 9.8 and
because the Rational Formulae possess in-built flexibilities as brought out in
para 4.13 to 4.15, the Committee feels confident that the Rational Formulae
can be adopted on the Indian Railways.
113
(Vol.1)
10.
PRE-REQUISITES AND METHODOLOGY
TO IMPLEMENT THE RATIONAL FORMULAE
10.1
In any progressive organisation, personnel of management and supervisory
levels should thoroughly understand the principles of manpower management
and financial implications thereof.
This knowledge should not only be
confined to personnel management department, but should necessarily
spread to technical staff in the field. Rationalisation of manpower is a vital
step in promoting efficiency and the sense of fairness to workers.
The
Committee therefore recommends that the knowledge of Rational Formulae
should percolate right upto the lowest tier of supervisors.
Not only the
formulae but also their rationale should be taught in IRICEN/Pune and in
Engineering Training Centres of the zonal railways. The office staff who are
engaged in carrying out annual review of gangstrength should also be trained.
They should be taken to field to see the ongoing modernisation efforts,
functioning of MMUs, day-to-day working of gangmen, etc., so that the
Rational Formulae are thoroughly understood in the context of field activities.
10.2
As soon as MCNTM Committee’s recommendations are accepted by the
Railway Board, the Report should be printed in sufficient number of copies, so
that all Sr.SE(P.Way) incharge, all AENs, DENs and Sr.DENs get one copy
each.
2 sets of floppies containing the software MANPOWER should be
supplied to each division. This can be done in 45 days time.
10.3
Within 3 months after the previous task is completed, IRICEN and zonal
training centres should impart the knowledge to all Sr.DENs/Coordination of
Indian Railways and to selected AENs, selected supervisors and office staff.
The course should incorporate on-hand training with application software
MANPOWER.
Officers and staff of Personnel and Finance departments
should also be trained, though not as intensively as Engineering personnel.
10.4
The Report should be permanently included in the syllabus of training
courses, both initial and refresher.
114
Exclusive training courses of 5 days
(Vol.1)
duration can be organised 3 to 4 times in a year at IRICEN and zonal training
centres on a regular basis.
10.5
The Rational Formulae should be applied, taking each P.Way section as the
basic unit, because manpower requirement for Activities M and S is computed
mostly section based. Formation of MMUs should be planned combining 3 to
4 P.Way sections under one AEN’s jurisdiction. One DEN’s jurisdiction can
be taken as the base for MMU, if medium capacity on-track tamping machine
(such as MP2000) is to be included under the Speciality Equipment of MMU
for carrying out slack attention. Such proposals should be initiated by DEN,
recommended by Sr.DEN/Coordination and approved by CTE/CE.
10.6
Sr.SEs should be fully involved since they have to collect field data precisely.
As regards apportioning of the total gangstrength of a P.Way section to
various
gangs,
Sr.SEs and SEs
should
carry
out ganglength-wise
calculations, judiciously distributing the manpower for Activities M and S.
Depending on the age of track, some mutual adjustments among ganglengths
can also be carried out.
approved by AEN.
These calculations should be scrutinised and
If this practice is well established, the supervisors will
become manpower conscious, the fundamental requirement for cost
consciousness.
10.7
When the first review of gangstrength takes place applying the Rational
Formulae, one of the following situations will emerge in each basic unit
namely P.Way section.
•
Calculated gangstrength is more than the sanctioned strength (this term
includes permanent and decasualised posts).
•
Calculated strength is less than the sanctioned strength.
The overall picture AEN-wise, DEN-wise and for the entire division should
also be projected in order to find solutions, by proposing transfers between
sections and between subdivisions.
Inter-divisional transfers can also be
thought of in case of optees being available.
115
(Vol.1)
Sometimes a division may
spread over more than one State, in which case transfer from one unit to
another unit may be resented due to genuine linguistic and education
problems.
10.8
The following procedure can be followed:
•
If the calculated strength is more than the sanctioned strength in any unit,
extra vacant posts of other units can be straightaway transferred.
•
If the calculated strength is less than the sanctioned and really operated
posts, such excess posts should be declared surplus immediately.
Thereafter the following steps can be taken:
1. Optees to other departments/other units can be transferred.
2. Incumbents of surplus posts can be transferred to the vacant posts in
other units.
Monetary grants or certain other concessions can be
offered, to encourage opting for such transfers.
3. Retirement wastage can be allowed to take place, particularly if the
incumbent has less than 3 years residual service.
4. For forming MMUs and for operation of on-track machines, incumbents
of surplus posts or even other capable gangmen can be encouraged,
trained and posted.
5. Taking recognised trade unions into confidence, transfers can be
implemented compulsorily.
In any case, during the above exercise, no additional posts should be created
in anticipation of wastage/surrender expected to take place in other units.
10.9
By carrying out these processes under close monitoring, it may be possible to
implement the Rational Formulae fully within a span of two years. Thereafter
the annual review should be carried out strictly as on 1st April and manpower
adjustment should be continued. By computer net-working it will be possible
to compile information at zonal railway headquarters and at Railway Board’s
office.
116
(Vol.1)
10.10 The Committee recommends that IRICEN/Pune should take over the
application software MANPOWER as the sole custodian and carry out
amendments from time to time. At the first occasion, this software should
incorporate MMU aspects, as soon as the principles recommended for
formation of MMU contained in para 4.11 and 5.7 are approved by the
Railway Board.

OBSERVATIONS OF THE FINANCE MEMBER AND
REMARKS BY THE TECHNICAL MEMBERS
Observations of Finance Member
Remarks by Technical Members
Indian Railways are passing through acute
financial crisis, contributed mainly by steep
rise in staff costs during recent years. The
costs of staff for Track Maintenance has
also gone up considerably and now
constitute around 82% of total revenue
expenditure under Demand-4. It was,
therefore, incumbent on the part of the
Committee to conduct Zero Base Review of
track maintenance activities to ensure
maximum reduction of existing Gang
Strength on Zonal Railways and also
suggest off-loading of certain activities to
outside agencies without affecting the
safety of Railway operations.
Substantial investments have been made
by Railways towards procurement of
sophisticated
and
high-tech
Track
Machines/Equipments over the years to
improve the quality of track structures and
curtail the scope as well as need of its
manual maintenance. The investments on
the Track Machines, in fact, was justified on
the basis of proposed reduction in the
number of staff deployed on track
maintenance activities.
The Special
Committee on Gang Strength Formula
(1979) gave due cognizance to this vital
aspect and introduced correction/reduction
factor of 0.50 on man-power norms for
maintenance of mechanised tracks as
compared to conventional track. Railway
Board have ordered, during Jan’83 , further
reduction of 5% on Gang Strength of
Gangmen arrived at with said formula.
It is agreed that manpower requirement
should be optimised duly considering
the financial
crunch, extent
of
mechanisation implemented and the
possible off-loading of certain activities
to outside agencies. Keeping these
objectives in mind, zero based
approach has been adopted, identifying
the essential subactivities of track
maintenance and the quantum of works
thereof, so as to maintain the track in
reliable condition commensurate with
the traffic carried.
Since implementation of the modified Gang
Strength formula in 1979, t+he capacity of

(Vol.1)
The track kilometre on Indian Railways
is 85429 km on BG, 19158 km on MG
and 3826 km on NG. Machine packing
has been introduced over 40287 km of
BG track only, leaving 68126 km totally
on BG, MG and NG still under manual
packing.
Even in machine packed
stretches, implementation of other
aspects of mechanisation is quite
insignificant as brought out in paras
2.9.4 and 2.9.5. Of course, machine
packing
provides
the
maximum
possibility for manpower reduction,
apart from relieving trackmen from the
arduous job of beater packing. It has
been clearly brought out in para 2.9
that, in the past 11 years, number of
trackmen has been reduced by 18.44%
despite increase of ETKM by 10.1%.
Further, the number of trackmen per
ETKM has been reduced by 25.93%.
The Correction Factor incorporated in
Special Committee Formula has helped
in optimising manpower, on adhoc basis

During interaction with Junior/Senior
Engineers of Zonal Railways, the
Committee had obtained particulars of
requirement of man-days for specific job
items under Category T&R. The relevant
data for 14 mechanised sections, with GMT
ranging between 12.5 to 68 GMT, are
shown in Table 1 to 14 of Vol. II. Even
though , the projected requirements of
Gang Strength for T&R Activity on the
mechanised track with average 18.6 GMT
& 29 GMT respectively by S.E. Railway and
N. Railway (Table 1 & 7) was deemed
reliable (Ref : Graph 1 & 2) the Committee
chose to ignore them, being on lower side.
It had, instead, resorted to Linear
Regression which appears as superfluous
since the actual man-days requirement
indicated by N.R. and S.E.R. are not only
deemed as reliable but also relate to
sections characterised by high density
traffic. By this process the man-days
requirements for said activities got unduly
inflated. The total man-days recommended
in the Draft Report for different activities
under T,R, M, S and outside Contract will
entail substantial increase in revenue
expenditure under Demand-4, over the
existing level, which IR can ill-afford.
While
analysing

requirement for Activity T on 14 P.Way
Sections on six zonal railways, data
collected on 5 sections were ignored
since the mandays appeared to be
inflated and the balance 9 sections were
considered for regression analysis, as
clearly seen by the pattern of
distribution of the points in Graph 1
(Volume 2). This is the standard workstudy procedure adopted internationally.
The Finance Member has opined that
only two sections should be considered
out of 14, so as to achieve a result
conceived under bias. This approach is
neither scientific nor rational, under zero
based analysis.
Likewise, while analysing for Activity R
(Graph 2 of Volume 2), 7 data were
ignored and 7 data were considered.
This method is also absolutely correct in
the opinion of Technical Members.
The concluding remark on ‘illaffordability’ has no basis, as proved
clearly through Appendices 5 & 6, para
4.12 and Chapter 9 that the Rational
Formulae help not only in optimising
manpower but also in achieving

Para 9.8 presents yet another
comparison between “No. of gangmen

Formulae” and “Sanctioned strength of
regular gangmen as per Special
Committee Formula”.
This also
indicates
further
optimisation
of
manpower being achieved.
a) In para 3.2.2, it has been well
explained as to why the manpower
requirement for LWR track is not
much different from that for
nonwelded track, in the present
situation. This is based on the
interaction with field engineers and
the experience of the Technical
Members.
Problems of welded
track have even attracted the
attention of Railway Safety Review
Committee. It is acknowledged by
the Technical members that the
suggested formulae require review
after 5 years, duly improving the
welding technique. (Para 0.8)
(a)
In Para 3.2 of Draft Report, it
is mentioned that LWR and Non-LWR track
have to be treated alike as far as
maintenance efforts are concerned and
hence track need not be classified based
on LWR or SWR or fish-plated for
categorising
sub-activities
of
track
maintenance. This is not correct and the
values for T&R activities should be worked
out separately for LWR and Non-LWR track
particularly as no maintenance efforts for
joints are generally warranted in LWR
Track.
b)
(b)
The man-days requirement
for mechanised track has been worked out
differently for different level of GMT. This is
not appropriate as the fluctuation of GMT,
say between 20 to 65, should not have
major
impact
on
Gang
Strength
requirements, as the basic maintenance
parameters and work contents remain the
same. Special Committee (’79) formula
also did not recommend granting of any
additional weightage above 20 GMT.
(c)
Separate provision of 10
man-days for ‘Minor curve re-alignment’
under Item T.1d is redundant as the same
is covered under Item T.2 (a) i.e., Pretamping operations, in terms of Para 226(3)
of P-Way manual. The realigning of curves,

The presumption that manpower

Mandays versus GMT is 2.3 for
machine packed track, whereas
the same is 8.24 for manually
packed track as per the Rational
formulae. This vital difference has
not been noticed by the Finance
Member. As could be seen in the
graphs at Sheets 7 & 8 of

attention.
(d)
Provision of 12 man-days for
‘repair welding (Item T.4) is very much on
high side and should be reduced to 6 mandays to conveniently cater to 300 to 400
failures, which is normal accrual per
annum. Incidentally, Eastern Railway has
reported around 100 failure during ‘98-99 &
‘99-00.
d)
(e)
Provision of 2 man-days for
lubrication of ERC is not justified as this
activity is undertaken
generally by
Keyman only.
(f)

be off-loaded to outside agencies or f)
undertaken by multi-purpose gang at
PWI’s headquarters, if found economical,
as per recommendations of Special
Committee (’79).
(g)
Provision of 55 man-days for
shallow screening under Item R.2 for
mechanised track appears to be on high
side. The Special Committee (1979)
recommended only 44 man-days for said g)
operation in conventional maintenance
and 29 days for Mechanised Track with 22
GMT. Further, with the introduction of FRM
(i.e., Shoulder Ballast Cleaner), 10 mandays may, at most, be involved for
preparatory work of FRM. This may be
reviewed and prunned down.
(h)
The basis of providing 10
man-days per KM. Per year for ‘Accident
relief and Carcass removal in run-over
cases from track’ (Item R.8) is not
understood as this cannot be a regular
activity. This item of activity, as and when
required, can be catered under Activity-S, h)
on the basis of actual requirement.
123
(Vol.1)
Tamping is done once in 2 years in
medium GMT line.
But minor
curve realignment has to be done
as and when defects appear. Para
226(3) of P.Way Manual indicates
that pretamping activity provides
right opportunity for carrying out
minor
realignment
if
found
necessary at that time.
Repair welding is done not only for
post-failure rectification, but also
for replacing defective welds
identified by USFD, cupped joints,
visibly cracked joints etc.
The
mandays requirement is based on
field data. (Table 15).
Some ERCs get stuck up requiring
extra assistance. 2 mandays per
year per km is quite meagre.
Loading and unloading connected
with emergency works and casual
renewals have to be performed by
gang. For planned renewals and
for bulk handling, contract will be
resorted to. This is as per the
existing practice and also as
suggested
by
the
Special
Committee.
The norm for no. of sleepers/head

10. Leave Reserve percentage of Gangmen
and other categories engaged in Track
Maintenance activities should be reduced
to at least 10% from existing level of 12
½% in view of enhancement of leave
encashment limit from 180 days to 300
days. This revised norm, in fact, is being
adopted during creation of posts of all
departments on this Railway, in the light of
the then M.S. (presently CRB)/ Railway
Board’s directives during Performance
Review Meeting with this Railway in
November,1997.
11. Man-days lost against absenteeism of
Gangmen should not be included in Gang
Strength formula, as provision of LR takes
into account the staff absent and not
available for work. Such provision will be a
retrograde step. The suggestion in the Draft
Report about diversion of money saved due
to LWP of Gangmen towards contracting
out arrear work will not only be
cumbersome but may induce more & more
absenteeism on the part of Gangmen with
serious ramifications. This should be
dropped.
127
(Vol.1)
As such, the gangmen avail all kinds of
leave in full. They are neither interested
in, nor capable of encashing unavailed
leave, unlike staff of other cadre such
as office staff, supervisors and officers.
Hence the existing practice of providing
12½% LR should continue.
30% LR is provided for running staff.
This has not been reduced, despite the
enhancement of leave encashment from
180 days to 300 days.
The Technical Members too are keen in
controlling absenteeism.
They have
made recommendation to remedy the
root cause of absenteeism and to
improve the health of gangmen through
yoga. They have also recommended to
take stern punitive action against
habitually absent gangmen.
After
optimising the manpower through
Rational Formulae, there is no leeway
to compensate for mandays lost due to
absenteeism. In this computer age,
compilation of the details of money
saved on monthly basis is quite
possible. Technical Members do feel
that contractual mode to clear arrears of
maintenance works is certainly possible.
12. The recommendations in the Draft Report
about Trainee Reserve of 2% for the cadre
of Gangmen is not acceptable, as it will not
only be difficult to send gangmen out of
their sections for training
but similar
demands
may
come
from
other
categories/cadre
also.
This
should,
therefore, be deleted and training
requirements met from existing gang
strength & its LR provisions like all other
Deptt. & Category of staff.
Any transport organisation attaches
importance to training as a means to
sustain safety. This is the scenario
internationally. SNCF set apart 6% of
revenue expenditure for training.
Provision of 2% training reserve is on a
modest scale.
13. Considering the constraints of Trolleying in
heavy density track in recent period, all
Trolleymen, other than those attached with
PWI & AEN, should be surrendered
forthwith.
The terms of reference pertains to
gangstrength. Trolleymen do not come
under this. However this suggestion
deserves consideration and this has
been already implemented on many
zonal railways.
14. Based on MCNTM formula and norms,
overall requirement of Gang Strength
should be assessed on Zonal Railways
basis. Any surplus Gangman in one
Division should be re-deployed in other
Divisions having shortfall without fail. In
other words, no excess posts and men-onroll in any Division of Zonal Railways
should be permitted. Surplus or decasualised Gangmen, over and above
justified strength, should be declared
surplus and redeployed.
Transfer of gangmen from one division
to other division is not generally done.
However
individual
cases
of
redeployment
can

certainly
considered on their own merits, in
consultation of recognised trade unions.
General remark by Technical Members:
The Finance Member had drafted
observations based on the draft report brought out in Feb.2000, which was discussed
by the Committee on 2nd and 3rd March 2000 at New Delhi. Based on these
observations, many portions of the Report have been redrafted to amplify the points
where needed. Tables P, P1, P2, P3, Q1, Q2, R1, R2, S, S1, T and U have been
entirely recast and, thereby, significant revisions have been imparted to the Rational
Formulae to achieve a still better optimisation of manpower. Accordingly, the
application software MANPOWER was modified thoroughly. The pilot study conducted
on five Divisions on various zonal railways was redone. The Technical Members feel
that the major revisions thus incorporated in April 2000 version of the draft were not fully
appreciated by the Finance Member, when the Committee met on 18.04.2000 at
Calcutta and discussed on the April 2000 version. The observations of the Finance
Member given in this Chapter were communicated under his D.O. letter
No.FA/Policy/99-00 dated 27.04.2000, after he got the April 2000 version, which was
only marginally amended as the final one. The Finance Member is of the opinion that
the Railway Board should consider the remarks given by the Technical Members.

Dear Shri S. Gopalakrishnan,
Sub: Review of Special Committee Formula on Gang Strength.
Ref:
Your D.O. letter No. AGM/M/98/MCNTM.
Kindly refer to your above letter in which you have apprised ME about the
progress, difficulties and some suggestions. Board has agreed for the following:
1.
The name of the committee be ‘Manpower and cost Norms for Track
Maintenance’ (MCNTM) as suggested by you.
2.
The other terms of reference as indicated in para 12 of your letter have been
accepted by the Board. Board has also advised the committee to review
gang strength formula incorporating the suggestions vide para 16 of your
letter. Board has not agreed for para 17 since these are establishment
matters and cannot be dealt with separately. Further, ME has pointed out that
no casual labour recruitment to be suggested. One consolidated Gang
Strength has to be there for all types of works to be done by gang. Works not
tobe done by gang would always be done by the contractor and each work
should be clearly defined.
3.
Board has revised the target date and now the target date of 31 Oct. 98
should be adhered to.
With regards.

Sub-Performance unit Directo Maintenance Kilometre (DMKM) is defined for converting the
physical length of running track into an equivalent length of track representing the workload involved
in track maintenance by applying suitable weightages (para 2.4.1). Obviously this will be a redefined
version of the present ETKM. DMKM will be calculated as per the following formula:
DMKM = DMKM (running lines) + DMKM (marshalling yards and sidings)
=
LU(1+A+B+C) x K1 x K2 x G +
1 u (1+A+B+C)x K1xG

Length of track and equivalent length of special features in km in

A typical permanent way section or a gang length will have to be segregated into smaller
track segments based on variations in the parameters defined above. The DMKM of each track
segment with specific values for the various parameters will have to be calculated. Summation of
such DMKMs for different segments will then yield the DMKM of the section or gang length. The
above mentioned factors are explained and their values given in para 2.4.1.1 to 2.5.1.8.

---Commissioner of Railway Safety, Mumbai in his report on Derailment of 2723
Dn Secunderabad, New Delhi, A.P. Express between Kalhan and Mandi Bamora
stations of Bhopal Division of Central Railway on 16.6.97 has recommended the
following:“Wherein political agitation are likely to affect track safety, track patrolling
should be intensified for which a review of existing P.Way gang strength
should be undertaken and additional P.Way staff recruited wherever needed.”
Board desires to have Railways comments on the subject together
consolidated proposal/specific requirement for creation of post for such type of
patrolling during agitation etc. Also there is often a need for provision of patrolling for
in the permanent gang strength.
The railways may send these proposals for additional P.Way men required for
all such sporadic needs & also may advise as to what work is proposed to be got
done from them when they are not required for patrolling duties. If they can
compensate for permanent strength required to some extent, then the list of such
activities and extent of substitution may also be brought out.
The proposal for additional post required, duly vetted by Finance and
approved by G.M. may be sent at the earliest. A copy of the same may also be sent

are already under active consideration
of the Railway Administration and this
also figured in MOS/R’s address during
the GM’s Conference held on
05.02.1996.
However,
the
implementation of privatisation is
required to be fully gone into and
deliberated before a policy decision is
taken in this regard.
The above subject came up for discussion during CTEs seminar held on
07.07.97 to 09.07.97. No specific recommendation was made during the
seminar in view of a man-power committee already working on the items
related with these. As you would recollect, one of the terms of reference to
another committee on “Machine and man-power deployment committee”
(Railway Board letter No. 88/CE-1/GNS/1 dated 02.01.89) was to going to
question of off-loading of track works to contractors to the extent possible for
achieving better economy and efficiency. However, as seen from the Report
of the Committee, submitted in February 95, this item does not appear to have
been dealt with. As such, during the deliberations in the above seminar, it
was recommended that the track works to be executed through contractual
agency which did not figure in the report of Committee of machine and manpower deployment must be duly considered by the present man-power
committee.

Railway Board have approved these recommendations, the extract of
IRICEN’s recommendations on this item along with the Board’s decision are
reproduced below for consideration by the man-power committee working under your
chairmanship.
IRICEN’S RECOMMENDATIONS
2) Considering that a number of works
fall outside the regular duties of P.Way
gangs, there is an urgent need to
identify works which can be executed
through contractual agency.
The
Report of the Committee of Machine &
Man Power Deployment for Track
Maintenance does not appear to have
considered the above point.
BOARD’S DECISION
(2) & (3) Approved. However, IRICEN
who are a member of the Committee
should give their views to the
committee for deliberations.
3) This aspect may be considered by
another Man Power Committee which
has been set up with the objective of
modifying gang strength formula. This
Committee may be asked to give the
recommendations keeping in view
those of the Machine & Manpower
Deployment Committee.
A list of items of work which may be executed through contractual agencies is
enclosed for consideration of the Committee.

Ministry of Railways (Railway Board)’s
letter No. 97 E/MPP/1/9 dated 13.10.97
The GMs/OSDs,
All Indian Railways.
Sub: Manpower Management in Gangs.
---It is observed that on some of the Zonal Railways, the existing gang strength
is not in conformity with the gang strength as per Special Committee Formula and
the annual review is also not being done regularly taking into consideration creation
of additional assets. There are also a number of instances of long absenteeism in
the gangs. Instances have also come to notice where the gangmen have been
deputed for carrying out various other works which are not the legitimate duty of the
gangmen. All these things affect the normal maintenance of track adversely which in
turn affects the safe movement of traffic.
For proper upkeep of the track, it is necessary that all the posts of gangmen
must be filled so that track could be maintained satisfactorily. For curbing a large
number of absenteeism in gangs, stern action be taken against the habitual
absentees. The gangmen should be deployed for their legitimate duties and should
not be diverted for other miscellaneous works. The above directives are required to
be ensured in the interest of safety.
The posts of gangmen should be considered in safety category and
necessary posts as per yardstick should be created. The matching surrender for this
purpose should be provided as a matter of top priority. The extent instructions of 2%
reduction in manpower will also not be applicable for gangmen.
The legitimate duties of gangmen are given in IRPWM and are enclosed
herewith as Annexure A. In addition various other works are also being carried out
by decasualised gangmen and the list of some is enclosed as Annexure B. In case
there is shortfall in working strength of decasualised gangmen, it may become
necessary to temporarily let out some works on contract which are allowed to be
contracted out to avoid accumulation of arrears in the works of decasualised
gangmen.
This has the approval of the Board (FC, MS & ME)

NATIONAL FEDERATION OF INDIAN RAILWAYMEN
MEMORANDUM ON GANG STRENGTH OF PERMANENT WAY GANGS –
CIVIL ENGINEERING DEPARTMENT
GANG STRENGTH OF P.WAY GANGS
The present approved formula for working out Gang Strength (Special
Committee Forumula ) for carrying out track maintenance operation is :
N
=
MKE
where N
=
Number of Men per Kilometer
M
=
Man power factor based on number of Man days required
and Man days available in a year.
K
=
Correction factor based on method of maintenance and
type of structure.
E
=
Equated track Kms.
The Railway Board while approving the Special Committee formula, ordered a
blanket reduction of 5% on the strength of Gangmen arrived at with the said
formula and do not include mate, Keymen, L.C. gateman and Leave reserve.
2.0
MAN POWER FACTOR
Man power factor is a factor giving the weightage for the actual mandays
required to do normal P.Way maintenance in a year vis-à-vis the actual
number of mandays available. This depends upon the job content for P.Way
maintenance and the output of Gangmen.
2.1
MANDAYS
The details of job contents and mandays required for manual maintenance
and maintenance and Mechanised maintenance are shown in Annexure. It
could be seen from the Annexure that the mandays required for manual
maintenance are 429 and for machine maintenance 473.
Number of working days available per year (approximate) ; 290
18
Annexure-N
The factor ‘M’ works out to 1.47 for manual maintenance and 1.63 for
machine maintenance.
2.2
In the Special Committee formula, the madays required for through packing
are shown as 174 for manual maintenance. In the mechanised maintenance,
even if the machines do tamping once in two years, the overall requirement of
mandays is not reduced, since the following works are required to be done by
Gangmen even in machine maintenance also.
a)
b)
c)
d)
e)
f)
g)

Rail/Weld failures
Emergency repairs
Permanent repairs.
Greasing of Elastic Rail Clips.
Greasing of gauge face of Rails.
Attending to derailments/restoration.
Signal failures/Men/Cattle run over et.
Clearing trees, for signals , level Xings , OHE.
Cess repairs , side drains cleaning, weeding,
Boxing of ballast etc.
While arriving at the factor M, the above items are required to be taken into
consideration for the machine maintenance. The manpower factor is further
influenced by –
-
3.0
Inclement weather conditions.
The present day stamina and output of gangmen.
Deployment of gang women
Non-availability of sufficient time to work on track due to increase
In number of trains and less gap between trains.
Correction factor – K
Correction factor is the factor required to be taken because of modernisation
of track. It was felt that efforts required to maintain the long welded rails and
concrete sleepers are much less com pared to fish-plated track. In actual
practice, reduction in the efforts is not much due to introduction of
19
Annexure-N
Higher pay loads
Higher axle loads and mixed Traffic
Introduction of Box ‘N’ wagons
Non-availability of adequate time intervals to attend track between trains.
Higher speeds of passenger & express trains.
Further, LWR and concrete sleepers will need sophisticated maintenance and
careful deployment of man power ceiling for frequent attention to maintain
zero defect requiring frequent deployment of Gangs. The Special Committee
formula adopted at 0.5 for mechanical maintenance needs to be modified to
0.75 as reduction in effort is considered marginal.

In the existing formula, the alignment factor restricted to curves sharper than
1.5° for BG. This factor needs to be applied to all curves irrespective of
degree since maintenance effort required for curves is same in all cases.

Annexure-N
In the light of the above, N.F.I.R. urges that the formula is required to be
Revised suitably, besides taking into consideration :1)
requirement of 30% leave reserve of Gangmen as against 12 ½ %
now due to working conditions being hazardous leading
absenteeism.
2)
requirement of 12 ½ % Trainee reserve as Gangmen are expected
to be given regular in service training.
3)

MEMORANDUM TO THE COMMITTEE APPOINTED BY THE
MINISTRY OF RAILWAYS TO STUDY THE SPECIAL MODIFIED
FORMILA FOR TRACK MAINTENANCE.
---INTRODUCTION
There has been continuous and serious complaint all over the Railway system
regarding the inadequacy of manpower for regular maintenance of track, patrolling
duty – monsoon, security etc., handing of heavy track materials, leave reserve, staff
against man days lost due to absenteeism, speed restriction duties and
decasualisation of casual labour etc. in the matter of maintenance of track and allied
works. This matter was continuously brought to the notice of Railway Board by the
Federations in the for a of PNM and JCM Departmental Council (Item No. 76/89).
Ultimately a meeting was held between the two Federations, i.e. AIRF and NFIR
with the Railway Board represented by Member Engineering on 27.11.1995, when it
was decided to appoint a Committee to go into the question of adequacy of the
strength of Gangmen, Keymen, Gatemen, Watchmen, Patrolmen etc.
2.
APPOINTMENT OF THE COMMITTEE
The present Committee has been appointed by the Railway Board Vide their
Notification No. 95/CE-1/CNS/2 dated 5.1.1996 and the terms of reference has been
amended vide Railway Board’s letter of the same number dated 13.5.1996.
The Railway Board vide their letter No. 95/CE-1/CNS/2 dated 23.5.1996 have
intimated a terms of reference and advised both the Federations – AIRF and NFIR,
that they may submit Memorandum to the Committee.
2.1
TERMS OF REFERENCE
i)
To study the Special Committee Formula for Gang Strength and to suggest
modified formula covering certain variables left out in the existing Special Committee
Formula which affect track maintenance effort.
ii)
The Committee shall take into account the decasualisation done, effect of
machine maintenance and track modernisation.
3.
SPECIAL COMMITTEE FORMULA AND ITS BROAD SHORTCOMINGS.
Norms proposed in the formula are not based on any study as will be evident from
para 3.2 of the report which read as under:“No field studies were conducted by this Committee for arriving at the norms……….”
25
Annexure-O
3.1.2 Provision of leave reserve of Gangmen, provision for second Keyman, man
days lost etc. and shortage of Trolleyman, Gateman, Watchman (for temporary
restrictions) were not considered. Minimum time available due to heavy density of
traffic was not taken into account.
3.1.3 Use of heavier weight of rail,
account.
sleeper, fish plate etc. were not taken into
3.1.4 Fatigue involved in walking and working in long stress and for working in
vagaries of weather.
3.1.5 Days available for working calculated wrongly, 30 days LAP and 20 days
LHAP were not taken into account as on day number of Paid Holidays has been
increased from 3 days to 12 days.
3.1.6 Man days required for Mechanical Track Maintenance are more than the
Manual Maintenance.
In the Special Committee formula, the man days required for through packing are
shown as 174 for manual maintenance. In the mechanised maintenance , even if
the machines do tamping once in two years, the overall requirement of man days is
not reduced, since the following works are required to be done by Gangmen even in
machine maintenance also :a)

Greasing of gauge face of Rails
Attending to derailments/restoration
Signal failures/Man/Cattle run over etc.
Clearing trees, for signals, level Xings, OHE
Cess repairs , side drains cleaning, weeding, Boxing of ballast etc.
While arriving at the factor M, the above items are required to be taken into
consideration for the machine maintenance. The man power factor is further
influenced by –
-
Inclement weather conditions
The present day stamina and output of gangmen
26
Annexure-O
-
Deployment of gang women
Non-availability of sufficient time to work on track due to increase in number of
trains and less gap between trains.
The present Committee is , therefore, urged upon to take all the above factors also
into consideration while fixing up Gang Strength.
3.2
Factors to be calculated afresh so as to ensure correct reflection of time
available for works on the track, heavier rail, sleeper and fish plates, less number of
working days available , fatigue involved.
Number of leave reserve, shortage of Trolleyman, Gateman, Watchman
temporary restrictions) also to be taken into account.
( for
3.3
Factors taken into account ultimately left with the decision of Zonal Railways
should be taken into account in view of the fact that appointment of fresh faces as
casual labour has been banned w.e.f. 1.1.1981 and no casual labour could be
appointed for undertaking the jobs as enumerated in Paras 3.3.1, 3.3.2,3.3.3, 3.3.4,
3.3.5, 3.3.6 of the report of the Special Committee. Please also see Annexure V, Sl.
Nos. 2,3,12,15,18 and 23 (points raised by AIRF).

Gangmen are entitled for 30 days LAP, 20 days LHAP and 15 C.L. In addition due
to heavy manual labour in open sky, braving torrential rain, scorching sun and biting
cold, they often fall sick and absenteeism due to sickness, most of the time
exceeds the limit of entitlement of leave. Replacement of them are necessary even
for a short period. As such 30% leave reserve posts need be provided.

Due to fast changing of working pattern, the Gangmen need intensive training. But
they cannot be spared for training for want of replacement. As such 12.5% posts of
Trainee Reserve need to be provided.
7.
Man days lost.
Prior to and during 1960s and 1970s also extra staff used to be sanctioned against
absenteeism beyond the number of leave reserve as ‘Man day lost’. This has been
stopped of late with the ban in recruitment of casual labour.

Gangmen utilised for meeting contingencies.
Whenever there is shortage of Gateman, Trolleyman, Watchman/Chowkidar,
Gangmen are drafted to perform the job of these categories also to be provided in
Gangman cadre.

In view of the above, the All India Railwaymen’s Federation urges that the present
Gang Strength Formula be revised with due consideration to the following salient
points:
i)
ii)
iii)
iv)
The duty of Gangmen starts and ends at Tool Box. They are to work within
their beat of 6 KMs daily.
Due to heavy manual work, in open sky during scorching sun, torrential rain
and biting cold, their absenteeism (sickness) is high.
They are to perform duty on running track where day to day density of traffic is
on high increase, as a result of which they get little time to perform their job on
the track.
Due to use of heavier rail, sleeper and fish plates more than man power is
necessary to handle them.

vi)
With the ban in recruitment of casual labour introduced from 1.1.1981, all the
works connected with track maintenance, patrolling of different types etc., all
the staff required for the entire gamut of track maintenance etc. works are to
be performed by regular employees only.
Due to ban in recruitment average age of Gangmen has been increased
from 30/35 to 40/45 years.
It is also urged that :

As per the admissibility of different types of leave, paid holidays and
absenteeism due to working condition and taking into account of ‘Man days
lost’, strength of Leave Reserve be increased to 30% taking the strength of
Gangmen, Trolleymen, Gatemen and Watchmen together as they are drawn
from Gangmen only.
12.5% Trainee Reserve Posts be sanctioned so that the Gangmen can
undergo intensive training to meet the need.
Patrolmen for monsoon patrolling, hot weather patrolling, cold weather
patrolling and security patrolling be sanctioned as they are at present drawn
from the regular Gang.
At least two ‘Look out man’ per Gang be sanctioned so that the men at work
can perform their duty with undivided attention.
As water is not available at the site of work and to be fetched from far flung
areas, Waterman be provided with each Gang.
Special Gangs for performing loading, unloading and sundy jobs be
sanctioned at each beat of P.W. Mistries.
Regular staff may also be provided for performing ancillary work for which
casual labours were recommended by the Special Committee.

EQUATED TRACK KILOMETRE AND GANG STRENGTH
1.
PREAMBLE
1.1
MAFLIN'
S FORMULA
Railways had adopted since 1931 the Maflin'
s Formula for deciding gang
strength. The number of gangmen required for maintaining one mile of track
was directly correlated to the average number of trains running on the track in
a day as tabulated below:
BG
> 30 trains/day
20 to 30 trains
per day
10 to 20 trains

As seen above, tracks of BG, MG and NG were assigned with specific "Unitper-mile" depending on the traffic carried. Having reckoned "Unit-per-mile",
the same is multiplied by 2.5 to get the number of gangmen per mile. In other
words, Manpower Factor is a constant, irrespective of track gauge.
This formula, though appearing empirical, brings out the rationale that the
maintenance effort varies in accordance with the quantum of traffic.
1.2
REVISED MAFLIN'
S FORMULA
In 1959, Lobo Committee was appointed by the Railway Board for revising
Maflin'
s Formula. The formula evolved by Lobo Committee is known as
Revised Maflin'
s Formula. The number of gangmen was based on the
"Equated track mile", which is worked out by attributing certain increases to
the running track mile, depending on traffic density, type of formation, curved
alignment and annual rainfall.
34
APPENDIX 1
The Revised Maflin'
s Formula was:
N=MxE
where N = Number of Gangmen,
M = Manpower factor, 2.3 for BG & MG Trunk Routes & 2.2 for other
routes in MG,
E = Equated Track Mile.
Implementation of Revised Mafiln'
s Formula was started in 1962.
2.
EQUATED TRACK KILOMETRE – FORMULAE FOR CALCULATION
Equated Track Mile – now adapted as Equated Track Kilometre (ETKM), is
calculated based on the Revised Maflin'
s Formula, with some modifications
introduced by the Railway Board at the time of acceptance.
2.1
RUNNING LINES (INCLUDES MAINLINES AND RUN THROUGH LINES IN
YARDS)
Equated Track Kilometre is worked out from the running track kilometre by
applying the following formula:
E = L x U (1+A+B+C)
E = Equated Track Kilometre (ETKM)
L = Running Track Kilometres.
U = Traffic density factor
A = Formation factor.
B = Alignment factor.
C = Rainfall factor.

b)
calculated for each segment with the respective value of the
factor and the total ETKM is obtained by summing up the
ETKMs of the segments. For a running line in yard, only the
quantum of traffic through the concerned line is considered.
In double or multiple lines, the traffic density factor may be
assessed for the average traffic density of the lines and applied
to all the lines.
FORMATION FACTOR (A)
This factor covers the nature of soil in formation/cutting and has the following
values:

This factor is of value 0.25 and is applicable to the length of track having
curve of radius less than or equal to
i)

1310m on BG (i.e. 1.5 and sharper)
o

36
APPENDIX 1
d)
RAINFALL FACTOR (C)
This factor is based on the annual rainfall.
C = 0 if annual rainfall is less than 200 cm.
= 0.1 for annual rainfall of 200 cm, increasing by 0.01 for every additional
10 cm rise in the annual rainfall subject to the maximum of 0.2
2.2
MARSHALLING YARDS AND OTHER SIDINGS
In the case of marshalling yards and other sidings, the equated track
kilometre will be as per the following formula:
E = L1 x U1, where L1 is the running length of such line in km

As speeds are comparatively low in sidings, factors A, B and C
are not taken in to account.
TRACK CONNECTIONS AND LAYOUTS
a)
The points and crossings and special layouts are treated as number of
sets on the following scale and ten sets are equated to one kilometre
running length of track:
Turnout
Diamond
Diamond crossing with single slip
Diamond crossing with double slips
Cross over
Three-throw
Scissors cross-over
Trap
Double trap
37
1 set
1 set
1 ½ set
2 sets
2 sets
2 sets
5 sets
1/5 set
2/5 set
APPENDIX 1
b)
The kilometrage thus arrived at should be converted into equated track
kilometres by applying the formulae mentioned in paras 2.1 and 2.2
above, as the case may be. The values of factors U, U1, A, B and C to
be used for working out equated track kilometre, in the case of layouts,
would be with respect to the more important line connected by the track
connection/layout. If a layout is considered to be part of siding, only U1
is taken into account, but not A, B and C.
c)
For turnouts, cross overs (ordinary and scissors), three throw, etc., the
through kilometrage will be measured along the main track and the
length of the track in sidings and loops will be measured from the heel
of the crossing and not from the toe of the switch. Similarly, in
diamond crossings with single or double slips, the curved lead of the
slip/slips will not be included in the length of track.
d)
The equivalent running length of layout computed as per para (a) will
be considered in addition to the physical length of the layout which is
treated as a part of straight track considered for conversion into ETKM.
In other words, the length of straight track of layout is not to be
deducted from the running length of parent track which is to be
converted into ETKM.
3.
GANG STRENGTH FORMULA EVOLVED BY THE SPECIAL COMMITTEE
ON GANG STRENGTH (1979)
3.1
NUMBER OF GANGMEN REQUIRED IN PERMANENT GANGS
N=MKE
where N = Number of gangmen,
E = Equated Track Kilometre (ETKM) worked out as per para 2,
M = Manpower Factor (1.47 for BG and 1.21 for MG & NG),
K = Correction Factor, due to modernisation of track, methods of
maintenance etc.
However, as per Railway Board'
s letter No.E(NG)/II/77/CL/46/E.Rly
dt.12.01.83, the gang strength as calculated by the above formula is to be
reduced by 5%.
Therefore the formula under adoption by the Zonal Railways is,
N = 0.95 MKE
38
APPENDIX 1
a)
MANPOWER FACTOR (M)
The M-factor for BG is 1.47 and for MG & NG is 1.21.
The basis on which these values have been computed is given below:

Therefore, Manpower factor M

= 1.43 = 1.21
Because of restrictions on working during monsoon, the days available for
through packing and shallow screening become limited to only 8 months.
Therefore, value of M for BG is increased to 1.47. Value of M for MG/NG is
taken as 1.21.
b)
CORRECTION FACTOR (K)
This correction/reduction factor is applied for sections having improved track
structure in place of conventional fish-plated track and/or where mechanised
maintenance is adopted in place of conventional maintenance. The value of
this factor is as follows:

The Special Committee recommended that the Railway may sanction
Casual/Seasonal labour for all these works as and when required on the basis
of volume of work.
The Committee also recommended engagement of extra labour gangs for
attending to isolated stretches of track due to exceptional formation problems,
for clearing drains involving heavy work and for major/frequent attention to
creep. Also they recommended that special permanent gangs may be
created for clearing sand dunes in certain desert sections. Creation of multipurpose gang at each PWI'
s headquarters for loading, unloading and
transporting of track materials was also recommended.

APPENDIX 3
DISCUSSION WITH FIELD ENGINEERS OF ZONAL RAILWAYS
As stated in para 4.2.1 of the Report, the information given by the field
engineers on norms for subactivities as adopted by them have been condensed in
Tables 1 to 14 and 17 to 19. Whatever could not fit into the tabulations and are
useful for consideration while making recommendations have been recorded here.
1.
Date: 02.06.98, Venue: Headquarters, N.Rly., New Delhi
Field Engineers present:
Shri A.P. Verma, SE (P.Way)/Line, Lucknow
Shri A.K. Sharma, SE (P.Way), Sonepat
Shri S.C. Giri, JE (P.Way), Bharwari
Points brought out:
1.1
Working hours are different in summer and winter.
1.2
LWR of one km length can be destressed by 40 men in 2½ hours. Balance
working hours of the day will be spent for preparatory and finishing works.
1.3
Crowbar packing is resorted to for slack attention to PRC sleepers since there
is no other alternative. Gangmen have learnt to do this, without damaging the
sleeper. One man can pack 20 continuous sleepers a day, without squaring
and respacing of sleepers. If the sleepers are scattered, 16 sleepers can be
packed. But in some sections the norm is 16 sleepers in both cases.
1.4
Cold weather patrolling is done generally between 4 a.m. and 7 a.m.
1.5
For overhauling of level crossing a norm of one sleeper per man is adopted.
10m wide LC can be overhauled by 16 men.
1.6
Entire work of greasing ERC is done by keyman only, from October to March,
on a programmed manner, at the rate of 160 clips per day.
1.7
One gangman can box up ballast over 16m length (25 sleepers), along with
weed removal.
1.8
Gangman avails fully LAP due. He is not interested in accumulating LAP for
encashment at the time of retirement. Hence Leave Reserve of 12.5% must
continue, inspite of LAP encashment having been increased to 300 days.
1.9
It is difficult to get gangmen during emergency out of working ours, since
ganghuts do not exist now.
43
APPENDIX 3
1.10
Absenteeism is rampant among gangmen.
1.11
Gangwomen are not able to work hard. Their number should be restricted.
1.12
Age profile of present set of gangmen is very unfavourable. There should be
medical or other tests to establish their weaknesses. In case a gangman is
declared unfit for the job, his ward should be considered for gangman post.
1.13
Gang tools must be standardised.
1.14
Uniform for gangmen for summer & winter and for night patrol should be
made better and more functional.
1.15
Gangmen must be paid cold weather and hot weather allowances.
1.16
More number of gangmen must be tested for A-3 Medical Category, for being
deputed as rest giver for gatekeeper.
1.17
Just like Rainfall Factor, a factor for temperature range should be introduced
to increase gangstrength in areas which are very cold and very hot.
2.
Date: 12.06.98, Venue: Headquarters, S.Rly, Chennai
Field Engineers present:
Shri D. Govindaswamy, DEN/W/Chennai
Shri M. Narayanan, SEN/TM/HQ
Shri K. Manoharan, Sr.SE/Katpadi
Shri K. Sekar, SE /Jolarpettai
Points brought out:
2.1
For slack picking, the norm is 12 sleepers/head. But the gangman has to
pack adjacent sleepers, if needed, due to lifting of track.
These are not
included in ‘12’ in some sections; but included in some other sections.
2.2
Overhauling of LC with PRC sleepers need be done once in 2 years, if
properly set.
2.3
For greasing ERCs, gangmen are deployed at the rate of 15 men per km in
one day.
2.4
Boxing of ballast can be done for 33m length per head.
2.5
Destressing of LWR is needed at interval closer than 5 years due to frequent
rail fractures.
44
APPENDIX 3
2.6
Shallow screening can be done at the rate of 5 sleepers/head if the whole of
crib and shoulder ballast is cleaned.
It can be done at the rate of 10
sleepers/head if either the crib or the shoulder ballast alone is handled.
2.7
Each Sr.SE should have one welding party.
2.8
Gangmen should not be transferred. There are many advantages by having
local villagers as gangmen.
2.9
Gangmen are not keen to save LAP. In fact they are not bothered about loss
of pay due to LWP.
2.10
Small track machines being supplied are of substandard quality.
2.11
Sr.SE should have a mini-bus (not lorry) for the transportation of gangmen in
case of emergency.
2.12
Gangmen should get extra diet allowance to keep themselves fit.
2.13
Procedure for issue of charge-memo to gangmen must be simplified and this
must be done without the need for vetting by DPO.
2.14
Computerisation of leave charts is necessary.
2.15
Same opinions as expressed in 1.12.
3.
Date: 22, 23.07.98, Venue: Headquarters, W.Rly, Mumbai
Field Engineers present:
Shri P.D. Chanchalani, AEM/East/Ratlam
Shri P.K. Goel, Sr.SE/Nagda
Shri R.M. Bengali, Sr.SE/Vapi
Shri Pankaj Saxena, Sr.SE/Navasari
Shri V.R. Gadwe, Sr.SE/Andheri
Points brought out:
3.1
Slack packing can be done for 25 sleepers per head, including squaring and
rectification of fasteners.
3.2
Due to signalling and track circuiting equipments present in track, particularly
in suburban lines, machine packing is not possible.
Manual packing will
continue.
3.3
Cupped welds are rampant. Frequent packing Is needed as though these are
fish plated joints.
45
APPENDIX 3
3.4
Shallow screening work is getting postponed with the hope that machines will
be deployed. But this is also not materialising.
3.5
In the industrial area near Vapi, rail corrosion near welds takes place calling
for collar painting. ERCs require greasing once in 6 months.
3.6
Pulling back creep in free rail track at bridge approaches is a major workload.
There are no creep anchors for 60kg rail. We may examine why rails cannot
be welded on bridge approaches.
3.7
Gangman is reluctant to work as RGGK.
3.8
Many track work contractors are failing, with the result, gangmen are
deployed for special works. This affects track maintenance.
3.9
With regard to suburban sections, non-availability of working time, problems
due to encroachments and lack of drainage, low productivity and lack of
personal safety during night work, were highlighted. These are elaborated in
Chapter 5.
3.10
Gangstrength formula should take into account factors such as, age of track,
corrosion prone area, very sharp curves, steep gradients, deep cutting, higher
speeds and running of BOX N wagons.
4.
Date: 01.12.98, Venue: Headquarters S.E.Rly, Garden Reach
Field Engineers present:
Shri Durgesh Govil, AEM/I/Bhilai
Shri G. Nagabushana Rao, AEM/Kirandul
Shri S.R. Ghosh, Sr.SE/Chakradharpur
Shri Umesh Srivastav, JE/Tilda
Points brought out:
4.1
Repetition of bad spots at the same location is a special feature on heavily
worked lines. Most of the effort is diverted for slack picking.
4.2
Keyman is able to complete greasing of ERCs, at the rate of 30 sleepers/day.
4.3
No extra gangmen are required for watching caution spots.
This can be
managed within the available gangstrength.
4.4
5 bridge timbers can be replaced by 20 men in one day.
4.5
The process of dismissing absenting gangmen should be simplified. Mass
Notification, Mass Enquiry, etc should be resorted to.
46
APPENDIX 3
4.6
Son of a gangman should be recruited as gangman, in case the father suffers
due to ill health during service.
4.7
Gangstrength formula should take age of track into consideration.
5.
Date: 02.12.98, Venue: Headquarters, E.Rly, Fairlie Place
Field Engineers present:
Shri E.B. Thomas, DEN/Dhanbad
Shri K.K. Majumdar, SE/Gomia
Shri B.N. Das, SE/Haribagh Road
Shri D.P. Upadhyaya, SE/Bhabua Road
Points brought out:
5.1
In Shivnagar – Durgavati section with traffic of 68 GMT (UP) and 42 GMT
(DN), tie tampers are not given blocks for 3 years and the deterioration is
mounting geometrically.
5.2
Packing of PRC sleepers with crowbar is done. But the retentivity is poor.
5.3
Yardstick for supervisors should be prescribed.
5.4
Stores responsibility with Sr.SE must be shared with Depot Store Keeper.
5.5
Levying of demurrage for wagon detention on par with consignees of trade,
causes too much of pressure to Sr.SE.
5.6
Absenteeism is rampant among gangmen.
6.
Date: 15.12.98, Venue: Headquarters, S.C.Rly, Secunderabad
Field Engineer present:
Shri T. Vidyasagar, AEN/Tandur
Shri O. Satyanarayana, Sr.SE/Kazipet North
Shri Ch. Narasimha Reddy, Sr.SE/Dornakal
Points brought out:
6.1
Crowbar packing of PRC sleepers is adopted for slack picking. Retentivity is
for 2 months.
‘Panjore’ make off-track tampers give better performance.
‘Mico Bosch’ make off-track tampers are also being tried.
6.2
Presence of clean ballast cushion is a pre-requisite for off-track tampers.
47
APPENDIX 3
6.3
Whether slack packing is done manually or by off-track tamper, the output per
head is the same.
6.4
Absenteeism among gangmen has to be curbed.
6.5
Gangman’s work is extremely hard on the entire railway system. He deserves
to be rewarded by giving appointment to his son as gangman. A number of
privileges are given to running staff.
Gangman category should similarly
receive special treatment.
7.
Date: 13.03.99, Venue: Headquarters, C.Rly, Mumbai
Field Engineers present:
Shri V.S. Solanki, CPWI/Sion/C.Rly
Shri R.S. Yadav, CPWI/Thane/C.Rly
Shri I.S. Rajput, CPWI/Dadar/W.Rly
Points brought out:
The field engineers explained the special problems encountered while
maintaining track of high density suburban sections, both during day and night
shifts. These are incorporated in Chapter 5.
8.
Concluding Remarks
8.1
All the Field Engineers strongly expressed their concern about the welfare of
gangmen. They stated that the strenuous job reflects badly on their health.
Medical category B-1 prescribed for gangman has nothing to do with stamina
aspect. A reliable method should be devised to declare a gangman as ’weak’.
Weakness due to loss of health should be treated as occupational hazard.
Eventhough gangmen’s wards, being rural based, have good stamina, they do
not get opportunity to become gangmen, whereas unwilling candidates are
dumped as gangmen on compassionate ground. This seriously affects the
productivity with repercussion on safety to passengers. The field engineers
opined that rules should be so amended that the ward of gangman gets
appointment as gangman, if his father is declared weak, in which case he
must be discharged from service on health ground, without being offered
48
APPENDIX 3
alternative job. In such cases the ward will get appointment only as gangman
and not in any other Group D category.
8.2
The field engineers also felt that absenteeism must be sternly curbed. They
also recommended that the money saved on account of LWP/absence should
be made available to enter into contracts to clear the arrears of maintenance
work. They are not in favour of resorting to casual labour engagement for this
purpose.
8.3
To avoid repetition, these points have not been mentioned in each of the
paras 1 to 7.
49
APPENDIX 4
REPORT ON THE COMMITTEE’S VISIT TO KONKAN RAILWAY
1.
The Konkan Railway having a route length of about 750 km passes through
hilly terrain. The single line has been constructed for a speed potential of 160
km/h. The track standards adopted were such as to minimize the needs for
track maintenance. The Committee, therefore, felt it appropriate to visit
Konkan Railway and accordingly the visit materialised on 12.05.1999.
2.
The track structure on Konkan Railway consists of 52 kg 90 UTS rails laid on
concrete sleepers with minimum ballast cushion of 250 mm. Gas pressure
welding was adopted for welding of panels of about 250 m length. These
were thereafter converted into LWR using SKV thermit welding process. The
turnouts have thick web tongue rails and CMS crossings and are laid on PRC
sleepers. Ballastless track has been provided in some of the long tunnels,
the objective being again to minimize the track maintenance needs.
3.
The track maintenance system on Konkan Railway is on the lines of ‘Fully
mechanised system having three tiers’ as recommended in the Report of
CMMDTM (Feb 95). It is seen that this system suits the conditions prevailing
on Konkan Railway. It consists of 3 tiers as follows:
3.1
Top tier
which comprises of on-track tamping machines, viz. 2 CSM
machines for the plain track and a UNIMAT for the points & crossings.
3.2
Middle tier
which consists of mobile maintenance gangs (MMG units).
These are responsible for attention to isolated spots. MMG unit is headed by
a PWI whose jurisdiction covers a length of about 100 km.
3.3
Bottom tier
which is headed by a Sectional PWI and is responsible for the
balance of track maintenance activities.
It has been named as Track
Maintenance and Monitoring Gang (TMMG). Jurisdiction of each TMMG is
about 50 km. Sectional PWI’s jurisdiction is further subdivided into 5 or 6
gang beats of approx. 8 km each. Each gang beat is headed by a Mate,
redesignated as P.Way Supervisor.
50
APPENDIX 4
4.
Principles of maintenance
4.1
Top tier:
The on-track machines are planned to be used for through
maintenance of track from one end of the railway to the other. However at
present, these are being used for attending the track in fairly long stretches
(of 100 m or more) based upon the results of TRC or OMS 2000 runs which
are organised on quarterly and monthly basis respectively.
In addition at
certain locations, heavy ballasting is involved primarily due to geotechnical
problems.
The on-track machines are being deployed at these locations
also.
4.2
Middle tier :
PWI/MMG is provided with a rail maintenance vehicle (RMV).
The vehicle is equipped with off-track tampers, NI track jacks, TRALIS jacks,
welding equipment, DG sets, hoists, etc. The RMV is fully equipped to carry
out all works involved in picking of slacks, welding, replacement of rails, etc.
2 nos. rails of 6.5m length can also be carried by the RMV. The vehicle is
manned by 6 ITI–trained staff in Grade Rs. 4000-6000 and designated as
Multi-Skilled Men (MSM). They are capable of driving the RMV as well as
carrying out all the aforesaid works. Thus they have the skills of Welder,
Fitter, Mechanic, Electrician and Driver.
The MSMs are dropped at the site
of work along with the tools and equipment and the block section is cleared
by the RMV. The MSMs are later on picked up from the work site. Every
year Konkan Railway experiences a large number of boulder falls and
landslides.
The RMV is also equipped with special drilling tools to drill a
number of holes in the boulder to enable breaking the boulder into smaller
pieces.
In due course, the RMV will also be equipped with blasting
equipment to clear larger sized boulders expeditiously. Selected MSMs are
proposed to be trained for this purpose.
4.3
Bottom tier :
This unit (TMMG) is being developed as an additional help to
pick up slacks. Off track tampers and jacks are being provided. This gang
also carries out other maintenance activities like cleaning of side and catch
water drains, de-weeding, casual sleeper renewal, etc.
The TMMG is
provided with jeeps/trucks. Thus they are not dependent on availability of
blocks to reach the work spot. However, as many stretches of KR are not
easily accessible by road, a motor trolley with a trailer of 1 tonne capacity is
51
APPENDIX 4
being developed for faster transportation of men, materials and equipment.
At present, TMMG is finding it difficult to transport the generator set of offtrack tampers to midsection and therefore they are not able to carry out slack
picking.
5.
Communication
KRCL is having a significant advantage of fast communication from any
location in midsection to the stations on either side. Sockets are available at
every kilometre which can be plugged in by the authorised persons and traffic
blocks taken and cleared from the site instantaneously.
6.
Works entrusted to Contractual Agencies.
A large variety of works are entrusted to contractual agencies. These include
the following:-
7.
1.
Transport of materials
2.
Cleaning of bridge waterways & drains before monsoon
3.
Overhauling of level crossings
4.
Greasing of ERCs
5.
Casual renewal of sleepers
6.
Destressing
7.
Shallow screening
8.
Cess making
9.
Deweeding
10.
Ballast supply, its training & dressing
11.
Restoration after accidents
12.
Painting of bridges & steel structures.
The Committee inspected track by travelling in RMV and observed that the
track geometry was not in such a perfect shape as expected. Low joints at
welds have developed and alignment was not up to the mark even in straight.
It was felt that a cautious approach is needed for copying KRCL model of
track maintenance, in view of the trend of track deteriroration noticed over a
short span of one year.
52
APPENDIX 4
8.
Conclusions
8.1
The total manpower employed on Konkan Railway for track maintenance is
much less. However, it has to be seen in the context of the newly constructed
assets which have borne only 3 GMT of traffic in the first year of its operation.
The predominant traffic is low axle load passenger traffic which does not
cause major deterioration to track parameters.
8.2
It is seen from para 6 that a number of works are being off-loaded to
contractual agencies.
A few of these items, such as, ballast supply & its
training and painting of bridges, are traditionally being executed through
contracts on the railways. However, in regard to regular maintenance works
(such as shallow screening, casual renewal of sleepers, cleaning of
waterways, overhauling of level crossings, etc.),
the Ministry of Railways
have given assurance to Corporate Enterprise Group that such works will not
be executed through contracts vide Railway Board’s letter No 87/W6/TK/12
dated
.08.88 (Copy at Annexure L).
The Committee cannot make any
recommendation contrary to this. Even if some unconventional step is taken
to let out some popular maintenance activities on contract, the contractors’
labourers may seek judicial route to get employed in railway in due course,
invoking the Contract Labour (Regulation & Abolition) Act. KRCL being a
newly formed quasi-government organisation, appears to have the leeway to
frame a different policy in this regard.
8.3
The 3-tier system of maintenance adopted on KR is also being practiced on
some sections of Indian Railways. There is no doubt that this is the best
system for maintenance of concrete sleeper track. There could however be
variation in matters of detail, such as, use of MP-2000 and/or a rail-cum-road
vehicle instead of RMV, and consequent operational differences. Ultimately,
the entire concrete sleeper track on the Indian Railways should gradually be
brought under the 3 tier system of maintenance.
The Committee
recommends that forming of Mobile Maintenance Unit should be encouraged
on being proved to bear financial advantage.
53
APPENDIX 4
8.4
It follows from para 7.2 that more and more skilled workers will have to be
deployed for maintenance of concrete sleepers on lines similar to multiskilled
men (MSMs) working on the Konkan Railway. Therefore, there is a strong
case to recruit ITI qualified men and induct them in the Mobile Maintenance
gangs. The gangmen can be encouraged to undergo ITI training through part
time courses.
Due to the changing social scenario, even on other than
concrete sleeper track, mechanisation i.e., 3 tier system, has to be
introduced, necessitating skilled and trained workmen. There will not be any
financial implication, since for creation of higher grade posts, monetarily
equivalent surrender of lower grade posts or vacancies is ensured.
8.5
The communication facilities on KR are excellent. These enable availing and
clearing block through telephonic talk from mid-section.
It is essential to
develop such facilities in the field on Indian Railways, as well as to amend
the provisions in GR & SR to enable taking and clearing block by contacting
from mid-section.
8.6
On Konkan Railway, the track is entirely new and is of the same vintage from
one end to the other.
In contrast, any typical P.Way section on Indian
Railways has stretches of varying ages.
The fire-fighting situations
warranting immediate deployment of gangmen as existing on almost all
important routes of Indian Railways, are totally absent on Konkan Railway.
The upkeep of track by KRCL cannot be considered as perfect as seen during
the Committee’s inspection. It is too early to conclude that Konkan Railway
model of track maintenance is successful.

In these sections, repeated attention is needed at certain obvious locations, such as
defective welds, glued joints, SEJs and approaches of L.C & bridges. In section 14, bad
formation problems too add up.
For loading/unloading excessive manpower has been projected.
Very low norm for shallow screening adopted along with excessive manpower
requirement for restoration of accidents.
Very low norm for boxing of ballast adopted.
SC Railway has suggested very low norm for shallow screening., (4 sleepers/head),
liberal manpower for loading/unloading and for pre-monsoon attention.

PLOTTING OF GRAPHS
A statement is compiled tabulating the results obtained in paras 1 to 10
above, in order to plot graphs for the visual concept of the savings achievable
by machine packing as compared to manual packing, with respect to the
maintenance cost/km and the no. of men required per 250km of track.
However it should be acknowledged that these do not include Activities M and
S. The cost of manpower for mates, keymen, artizans, etc., and cost of track
materials renewed and ballast recouped are also not included in the
maintenance cost. Due to these reasons, it will not be precise to calculate
percentage saving in absolute terms. Further, maintenance cost/km cannot
be compared with maintenance cost/ETKM worked out in Appendix 2.

APPENDIX – 6
THE RATIONAL FORMULA COMPARED TO
THE SPECIAL COMMITTEE FORMULA WITH CORRECTION FACTORS K
APPLIED FOR MACHINE PACKED TRACK
1.
The activities to be performed by permanent gangs as per Special Committee
Formula are more or less the same as Activities T & R in the Rational
formulae. This statement is more precise for manually packed conventional
track, rather than for machine packed modern track. This is because the
subactivities for modern track are different from those for conventional track
and the Special Committee Formula is based on the analysis of activities and
yardsticks for conventional track. However the Special Committee formula
has been made applicable for machine packed track, by stipulating Correction
Factors K as follows:
Type of machine packed track
2.
Value of K
Normal fish plated track
0.80
SWR Track
0.75
LWR track on metal or wooden sleepers
0.60
LWR track on concrete sleepers
0.50
The Rational Formulae have been based on data obtained from field
pertaining to machine packed track (LWR, SWR, Fish-plated, laid with various
mixes of sleepers) existing over 14 P.Way sections on various zonal railways.
Because of the scientific, rational and zero based approach adopted now, one
should not expect that the gangstrength calculated by the Rational Formulae
for machine packed track should have a firm correlation to that obtained by
the Special Committee Formula applying Correction Factors K, which were
just arbitrarily prescribed by the Special Committee. Still a comparison can be
made for theoretical interest and for gauging the financial implications due to
switching over to the new formula.
3.
The Rational Formulae evolved for manually packed track are only a
transformed depiction of Special Committee Formula as explained in para 4.3
98
APPENDIX – 6
of the Report and on the Graph 6. Therefore the comparison can as well be
made by calculating
•
mandays required as per Rational Formula for machine packed track
•
mandays required as per Rational formula for manually packed track
and by finding the ratio of the former to the latter, which is akin to correction
factor K. This is shown as follows:
Formula for
Activities T and R
A: Machine packed :
239 + 2.3 GMT
B: Manually packed :
391 + 8.24 GMT
A/B
2.5
Mandays requirement/yr/km

432
473
556
638
0.595
0.579
0.554
0.513
0.483
Thus it would be seen that whereas the value of K varies over a wide range
from 0.50 to 0.80, the value of A/B has a narrow range from 0.483 to 0.595
irrespective of the type of track. In as much as any P.Way section comprises
of a mix of LWR, SWR and fish plated tracks, Rational Formula will yield less
mandays requirement.
4.
Let us assume 3 typical mixes of LWR : SWR : FPR
Mix 1
Mix 2
Mix 3
LWR : SWR : FPR
K for the P.Way section
50 : 30 : 20
60 : 25 : 15
70 : 20 : 10
0.50 x 0.50 + 0.30 x 0.75 + 0.20 x 0.80 = 0.635
0.60 x 0.50 + 0.25 x 0.75 + 0.15 x 0.80 = 0.6075
0.70 x 0.50 + 0.20 x 0.75 + 0.10 x 0.80 = 0.58
Value of A/B in all these cases will vary from 0.595 to 0.483, depending on the
GMT carried (varying from 2.5 to 30 GMT), irrespective of the type of track.
Therefore it can be concluded that except in the case of lines with very light
traffic, Rational Formulae will yield less manpower requirement.
This
appears to be logically correct, since in the case of lines with light traffic,
mandays requirement for Activity R (which is constant) assumes a bigger
proportion of the total mandays requirement for Activities T & R.
99
APPENDIX – 6
5.
One more feature of Rational Formulae is relevant to be recalled. In the case
of Special Committee Formula, the effects of Traffic Density Factor U and
Enhancement Factors A, B & C are taken into consideration for the following:
•
Manpower requirement for all the activities to be performed by permanent
gangs, which include Activities T as well as Activities R.
•
Manpower requirement for all activities in case of running yard lines.
But in the Rational Formulae,
•
Enhancement Factors A, B & C are not applied for the manpower
requirement for Activities R of mainline. (Refer para 4.6)
•
Traffic Density Factor U and also Factors A, B & C are not applied for the
manpower requirement for Activities of running yard lines. (Refer para
4.7.1)
Therefore, when the gangstrength for the P.Way section as a whole is
calculated, manpower requirement will be on lower side, if Rational Formulae
are adopted.
6.
The results obtained in the Pilot Study conducted on five units (Chapter 9 of
the Report) as tabulated in para 9.8 validate the observations contained in
paras 3 to 5 above. Further as stated in para 3.2.2 of the Report, if the quality
of rail-welds and SEJs is improved in the course of next 5 years, it will be
possible to apply a reduction factor for manpower requirement for LWR track,
i.e., the future formula for Mandays/yr for machine packed track for Activity T
can be, r x (80 + 2.3 GMT), where r will be less than 1.
7.
Thus it may be concluded that the implementation of Rational Formulae will
result in better optimisation of manpower, as compared to Special Committee
Formula.

DOCUMENTATION ON APPLICATION SOFTWARE ‘MANPOWER’
1.
General
This application software has been developed for data entry and computation
of manpower requirement based on the Rational Formulae for manpower.
This software has been developed in Microsoft Excel (97 release)
environment.
The software is organised in two separate workbooks for computing
manpower requirement in non-suburban and suburban sections, namely,
‘MANPOWER’ and ‘MANPOWERSUBURBAN’. A jumbo version for the nonsuburban sections has also been developed to cater for the sections having
special features such as exceptionally large number of level crossings,
bridges, tunnels, curves, etc. This version has been christened as
‘MANPOWERJUMBO’.
A separate blank workbook has to be used for the section of each Sr. SE.
(Also refer para 3.1)
The workbooks of various Sr. SEs in a division can be compiled using
workbook '
REVIEW' to generate divisional review.
The workbook can
summarise data from upto 20 workbooks i.e. for 20 Sr. SEs. For divisions
having
more
than 20 Sr. SEs,
the Jumbo version of workbook
'
REVIEWJUMBO'can be used.

Special features :
3.1
When the software in original floppy is opened for the first time, it would be
seen that all the worksheets are having a few sample data entered, alongwith
computation thereof, to facilitate understanding of data entry and principles of
computation.
These are to be erased before entering data for any actual
application. It would be desirable to keep one original floppy write protected,
so as to serve for referring sample calculation.
3.2
On-line help for the data entry is available for all the data entry cells. Cell
specific '
INPUT HELP'appears as soon as user clicks in the data entry cell.
3.3
The shaded/coloured columns/rows contain formulae or fixed data to which
'
no data entry'or '
editing'is required.
3.4
Data entry should be made only in white columns of all the Worksheets.
3.5
Special care should be observed while entering the '
track km'and '
length'
.
3.6
The data entry to all the data entry cells is '
validated'
. This feature will warn
the user whenever an invalid data entry is made. The Software will also
display error message to guide the user by indicating possible reasons due to
which the entry is invalid. However, the program provides the choice for the
user to change the entry or to continue with the same entry.
3.7
The worksheets are protected and no column or rows can be added or
deleted.
3.8
The formulae in all the rows are locked.
3.9
Data entry in the various sheets should be done in the sequence in which they
appear in the workbook.

Note:
•
RYL : Lines on which trains are received on signal
•
NRYL : Non running lines in yard, marshalling lines, sidings, etc.
•
The maintenance of RYL and NRYL is entirely regarded as Activity R and
mandays requirement is computed as per the above table. Activities T, M
and S are not involved at all.
•
1 km of manually packed NRYL is equivalent to 2/3 km of manually packed
RYL, as regards mandays requirement.
•
Mandays tabulated above shall not be enhanced by the factors A, B and C,
which are applicable only for mainline track and not for RYL or NYRL.
7.
STAFF STRENGTH FOR MOBILE MAINTENANCE UNIT (MMU)
7.1
Gross Equivalent MMU mandays, i.e, GEMM over a subdivision/division
A.
For Non-suburban machine packed mainline (BG):
= Σ LM (40+1.15GMT) (1+A+B+C) + 35 Σ LM + 35 Σ L Y
where
LM = length (in km) of typical stretch of machine packed main line (BG)
LY = length (in km) of typical stretch of machine packed yard running line (BG)
B.
For High Density Suburban machine packed mainline (BG):
= ΣLH(75+1.5GMT)(1+A+B+C) + 120ΣL H
where
LH = Length (in km) of typical stretch of high density suburban mainline
Both for A and B above, the Chief Engineer can vary the value of GEMM and cadre
structure of MMU, depending on the local conditions, job requirement and efficiency
of MMU.
7.2
Principle governing the strength and composition of MMU
80% of annual emoluments of GEMM = Annualised cost of SEMMU + Annual
emoluments of MMU staff.
SEMMU is the Speciality Equipment of MMU, namely, on-track/off-track tampers and
vehicles (road, rail-cum-road, rail-borne) for transport of men and materials.
The cadre structure of Gangmen and pay scales thereof, as stipulated by the Railway
Board should be taken into account and Leave Reserve of 12.5% should be allowed,
while computing the annual emoluments of GEMM. The cadre structure and pay
scales should be taken into account and Travelling Allowance payable should be
allowed, while computing the annual emoluments of MMU.

ENHANCEMENT FACTORS A, B AND C
a)
Formation Factor A: This factor brings into consideration the nature of soil
in formation/cutting and has the following values:
Nature of soil
Shrinkable soil and vicious Black Cotton soil (very bad soil)
Ordinary unstable soil (bad soil)
Stable soil
Value
0.2
0.1
0
The Formation Factor should be applied only for the length of track having
very bad/bad soil conditions in formation/cutting.
117
APPENDIX – 8
b)
Alignment Factor B: This factor brings into consideration the curvature of
track and has the following values:
B = 0.25 for curves sharper than 2o, decreasing from 0.25 to 0
linearly for the variation 2 o to 1 o, and thereafter 0 for curves flatter
than 1o.
MG: B = 0.25 for curves sharper than 4o, decreasing from 0.25 to 0
linearly for the variation 4 o to 2 o, and thereafter 0 for curves flatter
than 2o.
NG: B = 0.25 for curves sharper than 7o, decreasing from 0.25 to 0 linearly
for the variation 7 o to 3 o, and thereafter 0 for curves flatter than 3o.
BG:
The Alignment Factor should be applied only for the length of track having
curves as detailed above.
c)
Rainfall Factor C: This factor brings into consideration the annual rainfall
and has the following values:
C = 0.2 for annual rainfall of 300cm and above, decreases from 0.2 to 0
linearly for the variation 300cm to 150cm and thereafter 0 for rainfall less than
150cm.
9
EQUIVALENT LENGTHS FOR TURNOUTS AND SPECIAL LAYOUTS
a)
The turnouts and special layouts should be treated as equivalent lengths of
straight track as follows:
Turnout
0.10 km
Diamond
0.10 km
Diamond crossing with single slip
0.15 km
Diamond crossing with double slip
0.20 km
Cross over
0.20 km
Three-throw points and crossing
0.20 km
Scissors cross-over
0.50 km
Trap
0.02 km
Double trap
0.04 km
b)
If a layout connects the Main Line (ML) to ML/RYL/NRYL, its equivalent track
length is added to the length of ML for the purpose of computing mandays
requirement. If the layout connects RYL to RYL/NRYL, its equivalent length
is added to RYL length. If the layout connects NRYL to NRYL, its equivalent
length is added to NRYL length. In other words, the equivalent track length is
added to the more important line connected to the turnout or special layout.
c)
The equivalent track length of layout computed as per para (a) will be
considered in addition to the physical length of the layout which is treated as
part of ML/RYL/NRYL, for computation of mandays requirement.
In
118
APPENDIX – 8
otherwords, the length of the layout is not to be deducted from the length of
parent track.
d)
The length of track in RYL and NRYL will be measured from the heel of the
crossing and not from the toe of switch. Similarly, in diamond crossings with
single or double slips, the curved lead of the slip/slips will not be included in
the length of track.
e)
In accordance with the mode of packing of the layout, its equivalent length of
track should be treated as machine packed or manually packed, for the
purpose of computing mandays requirement.
f)
Equivalent track lengths of turnouts and connections are considered only for
Activities T and R. The track length parameters wherever used for computing
mandays requirement for Activities M and S should exclude such equivalent
track lengths.
