What are the benefits of diesel locomotives?

Diesel engines deliver better acceleration, towing, and hauling potential than their gasoline counterparts. This is because within a diesel engine, the piston rises to the top of the cylinder, while in a gasoline engine it stops short. Diesel engines compress more air faster, delivering more power to get work done.
