Sure, why not? If it's heavy enough, there's every reason to have that much power on one train especially since there's heavy grade there. (Climbing in elevation) You need power to climb and dynamic brakes going downhill, so Helper Units are added-either pushers at the end, midtrain helpers cut in the middle, or just helpers at the head end, depending on length of the train, distibution of heavier cars, railroad preference in that area, etc etc. All over the country there are "Helper Districts" where pairs or more of locomotives wait on a siding to hook up or cut in to trains coming through just to help them get up and down steep grades. <br /> Anyone who knows more, please fill in my spotty information.-TANK-
