===================================================================== Whatever. I think it was understood that we are talking about wire pick ups on all wheels. Anyway, that is how I understood the question and if I was wrong in my interpretation, my apologies. Yes, the weak point is the connection through the gear towers in my opinion. ==================================================================== > Adding brushes to the frame side pick-up still leaves the frame hot > unless you take other measures to insulate the gear towers from the > frame.

Once you have disconnected the wire lead from the frame to the motor, the motor is electrically isolated because it is mounted to the frame by a bed of non-conductive glue. This point is critical for a DCC installation - all power to the motor must come through/from the decoder. Clear as mud, right? ;-) John Gibson Rocklin, CA The poll results are in.......
