Hello. I purchased a new HO scale GP-38 from Bachmann and would like to convert it to a dummy to serve as an MU in my consist. What is the easiest (and maybe reversible) way to do this? Possibly removing the gears from the drive wheels or removing the drive shaft? Thanks for any replies.
For the easist return to operation, you'll eather have to remove the drive shaft and worm gear, or the spur gear between the worm gear and the rest of the drive train. You'll need to do this on both trucks, otherwise the worm gear will lock up the drive train. You'll also want to disconnect at least one motor lead so it's not just sitting their spinning. Keep the removed parts where they will not get lost if you plan to put the loco back in operation at some point.

Thanks to Len for the advice. Can you describe what wire to the motor would need to be disconnected?
There are only two connections on the motor. Disconnecting either will work. Put some electrical tape on the ends of the wires to keep them from shorting against the frame.
