I purchased a U25C that had a frame that someone was kitbashing to end up with a unit that would ran better than it would with the Rivarossi frame and motor. From the prototype information that I have seen, the U25C trucks and the E33C trucks where the same.
The Kato frame that was used to kitbash has round pads, with no center pin, where the trucks attach. Does anyone know if the Bachmann Spectrum E33C trucks would work with the Kato frame?
