I'm looking for a replacement motor or chassis for this locomotive. Bachmann does not seem to list this item any longer. Not sure if replacement chassis will match.
Contact the service department - they should have what you are looking for.

If you can describe the motor/drive, a picture perhaps, I will have the motor you need.
