If you think an 18 car passenger train is a lot, then go to YouTube and dial up "2102 freight train". Before the passenger trip, the R&N hooked a 50 car coal hopper train to it first, and then upped that to 100 car. In all fairness the 100 car freight were empties but it was all uphill for it. There was also a 50 car loaded freight that was run so you know that 2102 can move at least a 5000 ton freight by itself.
