Adam Sounds like one heck of a train wreck! Your guess that something is out of alignment sounds right to me. Try checking the clearance between the flywheel and the rear bushing on the can motor. There is usually quite a bit of end clearance in the armature and if the flywheel slipped toward the bushing on impact it may be contacting. The same thing holds true for the worm gear on the front of the motor. The thrust load on the armature from the worm gear changes with the direction of rotation of the motor which may be why it only makes noise when backing. You didn't say whether the noise was pulsating or steady but it wouldn't hurt to check for binding in the drive rods. the best way I know of to do this is to remove the motor and gently roll the drivers. If they are bent or out of alignment they can bind in one direction but not the other. Best of luck, Ed P.S. May I suggest that you keep your track at least 3" from the edge of your layout? If you can't move the track how about adding a filler strip to the edge of the benchwork? It might avoid another crunched loco (OUCH)
