In addition to what others have said: Hill-climbing speed. For example, take Echo Canyon. Back in the 1960s, freights climbed that hill at 10 to 20 MPH. You could get ahead of them on the old road along the tracks without having to drive like a psychopath. But now, they climb that same hill at 40 MPH, because they have more horsepower per ton.

So railroads add a diesel to a steam train, and have the diesel supply the added power to take hills without slowing down. Then, on the flats, they (often) run the diesel at idle, and let the steamer do the work.

That said, this year UP ran 844 up Echo Canyon with no diesel (but with only 6 cars on). She was really fast, too.
