that won't work with the current setup, since the upper power connection is
controlled seperatly from the speed - that way the lights don't dim when
you slow down the train.  (which is cool on it's own).  Perhaps it's
possible not to do that, and then I think your idea would work - but I
don't know that much about the DCC, only what I could understand from Tom.

well, maybe it's a waste of money/receivers, but you _can_ put multiple
motors on the same channel, we did it in some of the larger motors.
