In the United States, diesel-electric locomotives are usually fueled in one of three manners: at an engine terminal, at fueling terminals along busy mainlines, and by fuel trucks wherever a fuel truck can get to a locomotive at.

Certain electric traction systems provide Regenerative brakes. The energy generated by the train is converted into electricity and return it to the power system that is available to be used by other trains, or to the utility grid in general.
Biodiesel & Renewable Fuels: Traditionally, locomotives have run on petroleum diesel fuel, but railroads are now using renewable diesel and biodiesel blends to power them.
The average fuel consumed per kilo- meter for all passenger and cargo trains is 7.97 L/ km. This value for local, trafficking, railway track laying and maneuvering trains is 7.92 L/km.
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
The 2022 CSX system-wide train efficiency metric, as shown above, equals approximately 520 ton-miles per gallon. In other words, CSX trains, on average, can move a ton of freight nearly 520 miles on a gallon of fuel, based on our 2022 revenue ton miles and 2022 fuel use.
Engines may be left idling to maintain important safety related functions such as maintaining engine temperature, air pressure for the brake system, the integrity of the starting systems, the electrical system and providing heating or cooling to a train's crew and/or passengers.
As more new locomotives are being added to the fleet, the older ones are moved to other less demanding tasks, like moving railcars in a hump yard. Many locomotives can last 30–40 years, depending on the maintenance done on them. Our GG1 Lasted 41 years, but many of the steam locomotives were retired early.
Are trains more efficient than cars and planes? If you mean energy efficient, yes, trains are far more energy efficient than cars (because they carry so much more people and freight) and planes (who spend so much energy to get 30K feet into the air.)
Freight trains are several times more energy-efficient than trucks, because 1) the rolling resistance of the steel wheels of trains is lower than that of truck tires on the road, and 2) trains encounter less proportional wind resistance than trucks since a train car is partly shielded from the headwind by the car in ...
