Gentlemen,
It's not the Tin Plate Trains, it's the wrong track and switches, if you want to run Tin Plate, use the correct track & switches for it, run Lionel Conventional Tubular with the 072/711 Lionel switches or FasTrack with the FT Switches. I run all my Tin plate Trains, original and MTH Repro all the time and never have any trouble with my couplers or derailing. I do not recommend Ross or GG track & switches for Tin Plate. If you want to run Tin Plate on modern low voltage Track & Switches run (RMT) K-Line Super Snap Track & Switches or FasTrack & FT CC Switches, all your Lionel type Tin Plate will run like glass on them.
Tim if he picked up that 269E Christmas set for $200.00 please tell me where I can call to purchase one, that is a steal of a deal!
