I don't think I've heard of this before, but... Has anyone rigged up a DC test track on a DCC layout using a spare decoder? I keep seeing DCC users saying that they couldn't test a DC loco because they don't have a DC power pack. So wire a disconnected length of track through a decoder to the power bus. Then you can see how your new loco will run when chipped. (Track will have to be very clean, as will the wheels.) OK guys, now shoot me down.
