Sometimes when my Climax derails the square metal rod drops out of the plastic channel on the front drive. This is the part of the drive train that powers the cylinders from the front motor. I have to roll it on its back and turn the trucks at an extreme angle to reconnect the drive. It looks like the rod or plastic sleeve are too short. Does anyone have a permanent fix for this problem. Of course I could derail less, but the grand kids have a habit of backing into the end of track bumpers at speed.

Thank you Art
