I have two older Mantua locos - 2-8-2 and 4-6-2. Both use motors coupled to worm-drive gears to run the wheels. Both use one pickup from the drivers and another from the tender - The driver pickup seems to consist of both motors being screwed directly to the frame - there's no visible wipers, brushes, etc. The motor comes off with one screw and has no other attachments. It sits on a brass pad that must somehow be picking up from the wheels.
Here's my question. For DCC, do the BRUSHES have to be isolated? Or the WHOLE motor?
Isolating the brushes on these would be easy enough. Isolating the whole motor a little tougher - I can isolate all day, but as soon as I screw it to the frame, no more isolation...
