New switchers
typically use a

Progress Rail Switcher Locomotive
Enormous Potential to Reduce
Emissions Immediately
Immediate capability to reduce NOx
and PM emissions quickly by replacing
older large engines in marine workboats
and switch locomotives
Immediate emission reductions
delivered to near-port communities.
Huge Benefits, But What
Does It Cost?
Use existing grant data and
anonymized cost data from
manufacturers
Will a new engine fit in the
engine compartment?
Can aftertreatment
technologies be incorporated?
Are there additional switchgear
requirements?
Can upgrade kits be used?
Replacing large engines is not
like replacing a commercial
vehicle. It’s a custom project.
What we learned
Large Engine Upgrades Deliver the Most
Cost Effective Emission Reductions
Engine Replacements
Deliver Benefits Quickly
How long do these
engines really last?
EPA assumes
switchers last 70 years
Marine Engines Last
Longer than EPA
Models Assume
What would the air
shed look like in select
ports if more of this
equipment were
replaced sooner?
Real World
EPA Assumption
Case Study: 34 tons of NOx
Reduced for Tacoma Residents
Recent Diesel Emission
Reduction Act Grant
$2 million investment to replace 1950s era
switcher with a Tier 3 engine
Benefits for communities
• Reduced 34 tons of NOx
• Eliminated almost 2,000 pounds of
fine particles
• Saved the rail operator 19,000
gallons of fuel
Case Study: 3.2 tons of NOx Reduced in Puget Sound
Cost: $225,000
Benefits Provided
• Reduced 3.2 tons of NOx per year
• Eliminated 400 lbs of fine particles
• Saved the operator 45,000 gallons of fuel
resulting in 1,000 tons of GHG emissions
“Island Chief” workboat engine replacement
• 2 unregulated propulsion engines
replaced with 2 Tier 3
• 1 unregulated auxiliary engine replaced
with Tier 4
Summing it all up….
• Diesel is the technology
of choice for large
engines
• The latest engine
designs eliminate tons of
emissions and save fuel
immediately
• Long working life further
enhances benefits of
investment
• Funding sources are
available today
