Canopus. I have the Bachman Forney, 2-8-0, Shay, 0-4-2, Gas Mech and street car. I haven't had a problem with a single one of them. At the time I got them I had thoughts of turning the 2-8-0 into a 1/35th scale Deutz and the street car into an Orenstein & Koppel loco. I think I'll just finish up...
