I have an Atlas/Kato RS-3 that generally runs fine. Today durring open house it was derailing on turnouts. One of the trucks would try to take the diverging route. While re-railing the engine after one of it's jumps, I noticed that there seemed to be a lot of play between the rails. Checking with an NMRA gage I find that the wheels are too close together.
Before I do somthing silly and break somthing, can somone tell me the best way to get these wheels back in gage?
Thanks.
