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.

For a fuel cost of $0.84 per liter of diesel ($3.17 per gallon) (AAR (2012b)), this results in an average running fuel cost of $185 per locomotive-hour. If actual train and operation data are available, energy models or rail simulators may provide more accurate fuel use values for specific conditions.
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
Thanks in part to these technologies, U.S. freight railroads can, on average, move one ton of freight nearly 500 miles per gallon of fuel, making rail the most fuel-efficient way to move freight over land.
The reasons for this are varied: from the privatisation of the rail industry to the rising cost of infrastructure. The UK does not have fixed rates like other European countries such as France, which can result in flight tickets being cheaper than a regional train journey in the UK.
In commuter services, GB TOCs' average cost are £ 11.29 per train kilometre, whilst European comparators produce a train kilometre at cost of £ 11.41. In regional services, GB TOCs produce a train kilometre at cost of £ 9.95 (ranking 5% above the average of continental Europe).
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.)
Federal regulators limit the speed of trains with respect to the signaling method used. Passenger trains are limited to 59 mph and freight trains to 49 mph on track without block signal systems. (See dark territory.)
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.
Even when switchyard locomotives are not moving trains, their diesel engines are usually kept running. This is done to charge batteries, warm engine fluids and meet other operational needs. This can amount to several thousand hours of idling per locomotive each year.
