I'm working on restoring the 1950's Athearn HO 0-4-2. Love switchers, just couldn't say no to this one. Stripped down and cleaned/ lubricated all the running gear and motor, it runs fine now. Well, except it runs in reverse. .. the negative lead goes across the frame to the right side of the motor. From what I can tell, it was designed this way. . .does anyone remember this/have a running example of it? I'm sure it's possible to isolate the engine and run new leads, just really curious.
PS> any restoration/detailing tips are much welcomed, as I've only been into HO for a couple of years. . .
