I recently bought an MTH 20-21217-1 VO 1000 from Trainworld. The smoke unit has melted/warped the shell. Evidently this is a known problem written about on the Forum that I didn't catch or didn't register with me. I'm worried about the same thing happening to my new Railking RS-3. I'm going to get the smoke unit serviced/reprogrammed, but was wondering if anyone knows if MTH is selling replacement shells.
