Cutbank has some weird problems.

I've been working on an activity where I take a 50-car double-stack train West from Shelby to Summit, and the double crossover (with the road crossing) at the East end of Cutbank will derail the train... If you're careful, by going say, at least 10mph slower than the 30mph limit and under constant dynamic braking, you'll make it. If you try to play around with the brakes at all, the train will jump the tracks.

I've had similar problems running Eastbound trains at the Cutbank bridge on the West side.

I'm all for the "as real as it gets" bit, but IMO, Cutbank does have some "program" problems...
