Introduction
Pittsburgh needs to reduce exhaust emissions from
transportation to within EPA standards.
The city moves 165,000 tons of freight by rail each
day. However, locomotive engines must now
meet EPA guidelines for Tier 3 level at
least.
The strategy in this report involves upgrading the
15 lowest mileage Tier 2 locomotives with after
treatment to Tier 3 for a total cost of $12.75
million; selling the 25 highest mileage Tier 2
locomotives at for $37.5 million, and purchasing
25 Tier 4 locomotives for $100M totaling a cost
of $62.5 million split into 2 installments over 2
years; and selling the 10 remaining next highest
mileage Tier 2 locomotives for $15 million and
buying 2 tow barges to compensate for, and
exceed the current capacity for shipping, at
$28.5 million for a net cost of $13.5 million.
Giving a total project cost of $88.75 million.

Transportation Mode Comparisons
Truck
Advantages
Disadvantages
.“Door to door” transportation
. Least environmentally friendly (emits 0.0063 lbs. of
hydrocarbons, 0.0190 lbs.CO2 ,0063 lbs. of N2O)
. Cargo capacity is the smallest
. Least energy efficient (59 miles per gallon)
. Need a lot more trucks in order to transport the same amount of
cargo as the Barge and the train.
. Costs the most amount of money to operate ($5.35 to transport
one ton of freight)
Train
. Can transport freight inland
. For this project, trains would need to either be upgraded or new
Tier 4s will have to be purchased.
. Can transport freight to location fastest
.Transportation is limited to the range and extent of the railways.
Barge
. Most environmentally friendly
. Can transport goods across bodies of water
. Can only travel through water. This is limiting because there are
only two rivers, Allegany and Monongalia which both feed into the
Ohio River.
. Costs the least amount of money to operate:
($0.97 per mile )
.Is the slowest mode of transportation compared to the train and
truck. (2-5 knot range)
. Can transport the most amount of cargo at a
time. (One 15 barge tow can carry 22,500 ton)

Transportation Infrastructure Condition and Capacity
Overall, Pennsylvania’s infrastructure received a C- letter
grade.
Pennsylvania’s road conditions are rated at a D-. This is
most likely due to the 8.8 million drivers that travel
almost 100 billion miles a year.
Pennsylvania’s bridge conditions are currently rated at a
D+. About 1 in every 4 of these bridges are considered
to be Structurally Deficient and about 1 in every 5 of
these bridges are considered to be Functionally
Obsolete.
Pennsylvania’s Inland Waterway system currently has a
rating of D+. None of the 17 dams in western
Pennsylvania have a satisfactory rating with three of
the 17 dams being in unsatisfactory condition.
Of Pennsylvania’s 17 locking systems three are of
satisfactory condition and six are of unsatisfactory
condition.
Pennsylvania’s Freight Rail System has a rating of a B,
meaning most of the rail system is in good condition.
Over 5,000 miles of operational freight railroads

Transportation Costs and Concept of Operations (ConOps)
The cost of transporting cargo by truck is $67.00 an hour or $5.35 to move one ton of
freight for every mile.
The majority of the cost comes from fuel costs and driver wages.
A typical tow barge carrying 22,500 tons traveling 100 miles per day costs $12,080 a
day.
This cost includes replacement costs, operational costs, and fuel costs.
To move one ton of freight one mile by barge costs approximately $0.97.
To move one ton of freight one mile by rail costs approximately $2.53.
A typical RVC is about 180%.
Regulations require workers to take time off between runs or shifts so that health of
the worker can be maintained. Operating the large vessels that carry such large
amounts of freight often come with very little space for the operator to drive the
vessel and workers can feel cramped in such difficult conditions.
Transporting freight by barge is the safest mode of transport and emits the least
amount of greenhouse gases.

EPA Diesel Emission Standards

Diesel Engine Exhaust Emissions (DEEE)
Pollutants:
CO - Carbon Monoxide
HC - Hydrocarbons
NOx - Nitrogen Oxides
PM - Particulate Matter
After Treatment Technologies:
DOC - within Tier 3 standards (reduce HC and CO by 60-90%, HC .12-.03 CO .6-.15)
DPF - within Tier 4 standards (reduce PM by 90%, .01)
CRT - within Tier 4 standards (reduce HC, CO, and PM by 95%, .015, .075, and .005)
SCR - within Tier 4 standards (reduce NOx by 95%, .275)
Alternative Fuels:
Electric - No emissions (from engine)
Natural Gas - significantly lower emissions (well within Tier 4)
Biodiesel - little or no conversion necessary, but higher $/gal
- - reduce emissions to Tier 3 (67% less HC, 48% less CO, 47% less PM, does
not reduce NOx significantly)

Locomotive Fleet Upgrade
The solution involves:
upgrading 15 Tier II locomotives to Tier III
buying 25 Tier IV locomotives
buying 2 barge tows
selling the 35 Tier II locomotives that will not
be upgraded
The locomotives that will be upgraded will be
those with the lowest mileage, and the
locomotives that will be sold will be those
with the highest mileage
This solution was the best balance of being
cost effective and environmentally friendly.
This solution has a final cost of $88.75
million, and will be implemented in parts
over a four year period.

Summary
Through our research we came to the conclusion that the most
economical and environmentally friendly solution for transporting at
least 165,000 tons of freight a day is:
15 locomotives upgraded and overhauled from Tier 2 to Tier 3
25 new Tier 4 locomotives will be bought with the money received
from selling 35 locomotives that were not upgraded from Tier 2 to
Tier 3
5 mineral trains would be in use and 12 freight trains would be in use.
Purchase 2 barges
= 189,000 tons of freight per day
