My little brother has a Union Pacific Steam Locomotive from Bachmann that has wheels forced up over the rail. JWhen it does move, it derails. I use the firms 18"radius curves and I wonder if that has to do with it.
NS:
Is it Bachmann’s Union Pacific 4-8-4 steamer? If so, an 18" radius may be a little too small for it. The radius may be forcing the lead truck to lift the cylinders, derailing the drivers. That’s a pretty big locomotive, and you might be better off using Bachmann’s 22" radius for the curves.
Also, if you’re using the Bachmann EZ-track, make sure that all of your connections from rail to rail are properly aligned. If one of the connectors has slid UNDER the rail instead of onto the bottom web, it will be lifting the rail at the joints and causing a derailment.

Never mind. It was dirty wheels and I discovered Windex DOES NOT work.
