ABSTRACT:
Electronic control circuits for model railroading including a reversing motor control circuit. An on-board electronic state machine indicates one at a time of a predetermined series of states including forward, neutral and reverse, and is clocked to the next state responsive to an interrupt in the track power signal. The circuit further includes reset means for resetting the state machine directly to a neutral state responsive to an interruption of the track power signal of extended duration. The state machine can be remotely programmed to reset to any desired one of the series of states in response to a track power signal interrupt. The unique reset state is useful for receiving various remote control signals without driving the motor.
