Being a small road running on train orders, with manual switches and a max speed of 15, the best way to play it is as engineer, watching for red or green flags on switches, stopping the train at each switch and for picking up the brakeman, and as brakeman, using the "8" free camera to walk around, throw switches and uncouple cars, waiting for the engine to back up and pick you up, hopping on the engine's front porch (Shift-2) or rear car (camera 3 very close to the car, not perfect but better than nothing).
It gives a very realistic local switching experience.

Using these and excluding bearing, track, and curvature variables, I came up with the following (rounded generously).The dead weight of the train is about 4700 tons. With a max grade of 1.5% about 140,000 TE is needed. The 3 SW1500's (42,250 TE each) produce about 127,000 TE. Short of what is needed by about 1 SW1500.
If the max grade is 2.2% the TE needed is 206,000. About 5 SW1500's. Train weight is an estimate based on info on coal cars which may not be correct and what weight is in the bin files I did not bother with. I am sure that someone could do a better job on the calculation, but I did find it interesting.
