I bought an MTH Commodore Vanderbilt from an estate auction, Stout Auctions. I "won" the auction. A couple of weeks later the loco arrived- and ("surprise!!") it was BRAND NEW, never run, and built in the early '90's (Proto 1). I put it on the rails, it would not run- smoked like an SOB, but would not move.
So, I found that the drive wheels were breaking up, cracking, defective metal somehow. It needed a new lower chassis assembly- the only way MTH sells the drive wheels. And worse- no parts available, from MTH or anywhere.
I wrote Mike Wolf for help in locating the part- not expecting warranty service, just hoping for help in buying the part. Then- WOW!!- day before yesterday- the chassis came via FedEx. Unbelievable!!!
It is my first MTH- but it won't be my last. I am going to Stockyard Express today to buy another MTH.
