Full Answer

Most diesel locomotives actually use a diesel-electric method of propulsion, which means that the diesel engine powers a generator that then produces the electricity used to run the train. Diesel fuel is one of the reasons that train travel is more energy efficient and more economical than air travel. Diesel fuel is produced at a higher volume per barrel of crude oil than jet fuel.
