We have an old White Pass & Yukon engine that we bought used. It has fallen over and the rear truck had broken off the chassis.
The arm attaching it to the chassis has also broken.  I noticed that it had broken before and iI think a part is missing.  We tried gluing it back on but we don't have the flexibility for the engine to stay running on the tracks. Not enough downward pressure. Does anyone have any ideas how to fix this problem.
