I got this chassis for a project knowing it need a motor, just want to double check, I'm assuming it would use an RS385 but I realize there are a few variations and this one looks like it may have bearings on either side of the worm gear so I'm curious and the MTH parts identifier isn't much help for this particular loco.
Also, it looks like this is scale driver version, which he large 86" wheels which is what I wanted. Wheels turn free so that's good, it was just cannablized for parts to fix other locos by a hobby shop.
