I recently acquired a Postwar Lionel 633 Santa Fe switcher. This is a low end piece from 1962, made one year only. The engine is unusual because an Alco motor truck was used. The motor truck does not have a couple, just an empty pocket. The collector truck has a non-operating truck.
As far as I know, the motor is double wound for use with a two position e-unit. Only one axle is driven.
Here is my question: the guide book I checked says it should have a traction tire, is that so?
The guide books have mistakes from time to time.
Also, has anybody seen this engine with a different power truck?
The one I picked up has:
double wound field
both axles driven
no axle bearings.
one traction tire.
I think the motor was probably replaced, but whomever did the work did a much neater, careful job than is typically seen.
