How many cars can a diesel locomotive pull?

Re: How many cars can a loco pull? The two important questions are how fast do you want them to run and how steep is the grade. One unit can easily pull 100 cars on the flat if you only want it to go 10-12 mph. Put it on a 2% grade and a 3000 hp unit can only pull about 6-8 cars at about 15 mph.

The Big Boy has the longest engine body of any reciprocating steam locomotive, longer than two 40-foot buses. They were also the heaviest reciprocating steam locomotives ever built; the combined weight of the 772,250 lb (350,290 kg) engine and 436,500 lb (198,000 kg) tender outweighed a Boeing 747.

Transit rail modes are measured in car-miles. Car-miles measure individual vehicle-miles in a train. A 10-car train traveling 1 mile would equal 1 train-mile and 10 car-miles.

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.
