At times I run Three [old] AM GP 7's hauling a very long coal train. I run DC.
I find that if my three engines are in excellent condition, they have no problem hauling the load. I try to keep my equipment serviced, and if the coal train starts having problems, my loco's need looked at. Presently, after a recent over haul, they are running fine. Whew, thank heavens!
