of this one train (and maybe pushers on the rear end).
Any of this is completely plausible.....in the right situation. Railroads are/were no different than any other business in not wanting to waste money. If you could do the job with one engine, there wasn't any reason to do multiple engines. That said, there are situations where multiple engines are needed.
#1...you can always put enough power on the front to pull a train. You can also easily break a coupler with too much power on one end. At a certain point, you need a rear pusher....or even mid-train helpers.
#2...if a good-sized railroad is running small power instead of a much larger engine, there is usually a good reason. Curvature, clearances, or restrictions on bridges are the big ones usually.
#3...extra power to get over the hill when the plan didn't work. Wet sand, bad coal, or whatever other issue can require whatever is available to get the train over the hill/out of the yard, etc.
There are some other situations where this could (and did) happen also. The key is that there has to be a rational reason for it.
