I started work this evening on a Picatinny Arsenal switcher - Lionel #42. Plaicng it on the track and applying power, I heard the sound of a motor running but no there was no motion. Looking inside, I saw that the gear on the axle was stripped - with brass dust next to it in the chassis.
The way this unit is built, replacing the gear isn't a simple task. The axle runs through the frame with gear in the middle and the wheels outside the frame. Has anyone done such a replacement. I can see a brute force way to deal with this one but would like to hear how anyone else has solved this problem.
