Reducing Pollution From Rail

Roughly three percent of the diesel exhaust in the Puget Sound region comes from locomotive engines, including passenger trains, line-hauls, and switchyard locomotives.

We help our rail partners reduce diesel emissions and fuel costs through:

Cleaner fuels
Repowering locomotives (replacing engines)
Retrofit technology (idle-reduction)
Upgrading engines
