The Electrification Maintenance
Challenge
• During CP5 Western Route Maintenance is characterised by 5
Principle Challenges:
» Increasing number of Assets (850 STK of OLE; +15%
additional S&C between Paddington & Reading; 35km
of new track alignment – S2K / Filton Bank)
» Increasing number of Trains & Tonnage
» Significantly reduced access for Maintenance &
Renewals
» 4 New Rolling Stock Fleets
» Dramatic increase in utilisation of existing MK3b OLE
System between Paddington and Airport Junction
The Maintenance Challenge - More
Assets
The Maintenance Challenge More Trains & Tonnage
The Maintenance Challenge 16% Maintenance Efficiency in CP5

Series 1: A Whole Life Cost OLE System
Series 1 Relaibility Comparison
Series 1 RAMS review indicates a 48% improvement in
reliability against Mk3b equipment and a 19%
improvements against Series 2.

Series 1 OLE for GWML Electrification
Series 1 provides mechanical and electrical
independence between Main and Relief
Lines.
Compliant to the High Speed Energy TSI
Compatible with High Output construction
methods.

Risk Based Maintenance
Risk Based Maintenance
“A process used to determine what must be done to ensure that any
physical asset continues to do what its users need it to do in its
operational context”
GWML OLE will be maintained using RBM Techniques
from Day 1 Energisation
Western Access
Point Strategy
Section number to go here
Western Route Access Point and
RRAP Strategy
• Foot access to track no more than 2 miles
apart giving a maximum walking distance of 1
mile to site for staff tools and equipment.
• RRAP no more than 4 miles apart giving a
maximum distance to site of 2 miles for RRV.
• Vehicle access at strategic assets such as
S&C, Distribution buildings and limits of
possessions will assist in rapid response times
and faster times to take possessions.
• Between Paddington and Maidenhead the
above distances will be reduced by 50%.
Isolation Strategy
Section number to go here
Western Route – Isolation Requirements
The Western Route Requirements for Isolations
Strategy requires:
Increase in workforce safety
Compliance with Electricity at Work
Regulations (Aligns with the Electrical
Safety & “Safety by Design” principles)
Alignment with CP5 E&P Asset &
Maintenance Policies
5 minutes (maximum) time to safe isolation
(required to meet 2019 Maintenance
commitments)
An isolation method that meets the Route’s
CP6 Maintenance Organisational size and
OPEX funding (specified to meet the Route
Requirement for 5 minute isolations )

RCM Strategy
Section number to go here
Remote Condition Monitoring Strategy
RCM will be installed where the following
criteria are met:
 Monitoring of wind activity
 Monitoring of contact wire uplift where OLE
uplift capability can be exceeded
 Monitoring of conductor tension at all
locations where restricted Maintenance
access exists for the inspection of spring
tensioning
 Measurement of pantograph uplift and
pantograph head condition by the use of
remote measurement & inspection
technology on service trains

Resilience
Improvement
Section number to go here
0-12m OLE – Why Improve Resilience?
Route Requirements significantly change by 2019
– High OLE Use By 2019
Significant rise in pantograph passages by 2019
due to introduction of IEP, EMU and Crossrail train services.
– High Reliability Required
0-12m OLE will be the heaviest used OLE on the whole route.
– High Performance Required
CP6 target of 96% PPM to be achieved.
– Higher Train Speeds
Electric train speeds increased to 125mph from 100mph.
– Low Maintenance System
Future access for Maintenance will be greatly reduced.
0-12m OLE – Resilience Improvement
Summary
Western Route is undergoing the biggest change to the
operational railway since Brunel
The scale and complexity of the challenge is immense and
involves a higher spend / mile than the WCML
The Route’s objective is to deliver a 21st Century high
performing, high capacity railway for a variety of traffics and
rolling stock types
The Western Route Maintenance Strategy is clearly
articulated plan to deliver a high performing railway through
8 Workstreams
In 2019 Western Route Maintenance will support a busier
railway – more efficiently – and with less access
