Convert an AC model To DC?

I would think that either way, that's what Dremels are for! Remember that guys have hacked away at old Alco Models brass diesels to install Atlas motors, trucks, bolsters, etc. I assume something similar could be done here -- even at worst cutting some heavy sheet brass as a new frame.

If you're able to cast your own bodies for various projects, I would assume you're capable of this.
