ABSTRACT:
A control circuit which will momentarily apply a pulse of power to the E-Unit solenoid in response to the momentary interruption of power by the transformer or another control signal. The E-Unit rest state is thus with no power applied, eliminating noise and saving power. A seek-to-forward cycling capability is also provided. The overall system has a remote transmitter and a base unit coupled to the train tracks with a receiver. The base unit controls track switching and individual trains through FSK signals transmitted over the track. The base unit also controls a triac switch between the transformer and the track to allow remote control of track power and impose DC offsets on the track power signal.
