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.
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.
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.
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.
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.
Hydrogen-powered fuel cells, combined with batteries to store electricity, would be a zero-emissions solution to replace the diesel-electric locomotive, Moslener says.
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.
Power plant capacity is far greater than any individual locomotive uses, so electric locomotives can have a higher power output than diesel locomotives and they can produce even higher short-term surge power for fast acceleration.

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.
Elements of the diesel locomotiveThe diesel engine may operate on the two-stroke or four-stroke cycle. Rated operating speeds vary from 350 to 2,000 revolutions per minute, and rated output may be from 10 to 4,000 horsepower.
