Was wandering if I could get some feedback on my issue. Running it on Atlas O-72" curves. Have just one big loop going to the left. If I back it up, the rear truck of one of the units comes off the track & kicks the circuit breaker on. Also, on a couple of the curves in forward that rear truck comes partly off the track. Sounds like it might be riding on the flange & just drops back in. Has anyone else experienced this issue? Any suggestions for a fix? When I look at it after it goes off the track, almost looks like it might be hitting the side frame in front of it, but hard to tell. The other "A" unit runs perfectly fine.
Thanks
