Title: B30-7 Rear Truck Derailing
Post by: Ken S. on August 20, 2023, 12:59:19 AM
A recently purchased B30-7 was track tested ad the rear truck seems to derail after the locomotive moves about an inch in either direction. I'm not sure what the problem could be. I know it's not my track though

Sounds like the drive shaft to that truck may be out of place. Only way to be sure is to pop the top and look.

I got the shell off and became lost as to what to do next.

I took the cover off of the rear truck and I still can't find anything wrong.

My GG-1 has ruled out a track issue.
