Please help if you can. I have two Altas Trainman U 23B's three rail units and they are both stalling on my switches. I have both Ross switches and classic Lionel. I thought the problem was the Lionel switch, so I replaced it with a Ross switch to test it.
It does not matter if I run these units in TMCC or Conventional, both units stall either way. I spoke with the Atlas reps at TCA York about this. They told me to take the grease plug out of the bottom and remove the red washer and replace the plug. I did all of this and I still get a stall. The units have pick up rollers on each end and appear to be made of copper. Would replacing the pick up rollers cure the problem?
