Heres a N scale MILW EP2 biopolar I got a trainshow on Sunday, the thing ways a ton and has two motors, but one of them has overheated and some of the plastic in it has meleted and it does not turn at all, Its a pretty nice custom built model and its made out of brass and a Atlas mechanisim.
The picture doesn't fit my screen so it's hard to see, but it does look like a good start to a unique model for your trainset. Good luck with rebuilding and painting it.
