What is the average lifespan of a diesel locomotive?
Usually 30 to 50 years but a diesel engine might be replaced by a more modern and efficient model after half that time. Likewise a locomotive's electronics can be upgraded, or adjustments to new signalling systems made.

BNSF Locomotives. We have one of the newest locomotive fleets in the industry. A typical BNSF locomotive will travel up to 4.8 million miles in its lifetime - equal to about 20 trips from the earth to the moon.
Santie Oil stocks train engine oil in 40–60-gallon drums or 40–260-gallon totes to help diesel mechanics keep locomotives in top condition. The Federal Railroad Administration requires train engine oil to be changed every 180 days (formerly 92 days), and the time may be extended based on the oil's condition.
Hydrogen-powered fuel cells, combined with batteries to store electricity, would be a zero-emissions solution to replace the diesel-electric locomotive, Moslener says.
Fuel Tank. This huge tank in the underbelly of the locomotive holds up to 5,500 gallons (20,820 liters) of diesel fuel, plus an additional 300 gallons (1,135 liters) of coolant, and 250 gallons (946 liters) of engine oil.
While many of us change our car tires every 50,000 miles or so, Metro rail wheels can travel as far as 700,000 miles before they need to be replaced. Good thing because changing the wheels on a single rail car can take more than a week, depending on the design of the car.
When it's moving at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake. An 8-car passenger train moving at 80 miles an hour needs about a mile to stop.
In temperatures below 40 degrees Fahrenheit, the engine has to be kept warm for engine fluids to work properly, as antifreeze cannot be used in locomotive engines. Engines are also kept running to provide air conditioning or heat for the crew, which may be aboard even if the train is idling in a yard.
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.
Most yard-switching and short-haul locomotives are equipped with diesel engines ranging from 600 to 1,800 horsepower; road units commonly have engines ranging from 2,000 to 4,000 horsepower.
The Centennials were the largest diesel-electric locomotives ever built. Actually comprising two engines on one frame, they delivered 6,600 horsepower. Designed and built exclusively for Union Pacific Railroad, the units were named in honor of the railroad's centennial anniversary celebration in 1969.
Trains measure in at 477 ton-miles per gallon of fuel, while for trucks it's only 145 ton-miles per gallon. [2,3] This is primarily because the rolling resistance of steel wheels on rails is less than that of rubber tires on the road. As a result, rail tends to be poorly suited for short trips.
