What I do not understand is why there is such a large variance in pulling power experienced by the owners of these engines. As I commented in the other thread my new UP pulled 14 Gilbert freight cars up a 2% grade around a 180 degree curve, no signs of slippage. When I get some free time I will see how many cars it will pull up a 2.4% grade before slipping or stalling.
