The AR1 Auto Reverse Unit operates your trolley or train in a back-and-forth operation on a point to point track. The board sits between your DC power pack/throttle/transformer and the track and reverses the polarity of the track power on a timed basis. In effect it automates the directional switch on your transformer.
