I have an undecorated Atlas Trainman GP38-2 that came with the Blomberg M style side-frames. I want to replace them with the Blomberg B style. Are all Atlas sideframes from other engines inter-changeable ??? Atlas doesn’t list part numbers for the Trainman GP38-2 (that I could find) on their site, and I don’t have the instruction sheet to look up the part numbers.
Mark.
