My design is more straight forward and not as cool as Will's. I put a 5114 9
volt motor just behind the blade and simply ran an axle out of it. I get my
power from a 5115 9 volt battery box (which has the two red switches for
forward and reverse, thus eliminating the need for a polarity switch) which I
place near the door in the center of the car for easy access. When I have it
sitting on the GMLTC layout, I remove the battery pack and run a motor wire
under the car to a transformer for power (also allows forward and reverse).
BTW, The rotary plow I'm modeling was essentially a boxcar with a rotary plow
slapped onto it, and therefore required a separate unit for power and
propulsion.
