Model Railroading > Athearn GP50 shell on Atlas frame?

Has anybody ever done this modification and is it possible? I was thinking of using a GP40/40-2 frame and motor, would that be the right one? Any pictures that might help me make it work?

Thanks,
Mike

With that in mind, I wonder why I haven't seen anyone use a Proto 2000 GP60 as a start for a Geep 50 yet. Surely, that shell is of higher quality than the Athearn GP50.

A correct GP60 is 13 inches longer in wheelbase and the body has extra length also. So it would not necessarly be a better starting point to make a GP50.

While I haven't tried this conversion, I would guess that the biggest problem you'll have is that the Athearn shell is fairly thick compared to the Atlas shell, so you'll have to either thin the insides of the GP50 shell, narrow the Atlas weights, or remove the weights and replace them with something else. The thick stepwells, or the ends of the frame, might also need some trimming to fit.
