Patent ID: 7211976

Claim:
A model train, comprising: a train car including a wheeled carriage adapted to travel on a track; a motor operatively coupled to the carriage to thereby cause the train car to travel along the track in at least one direction; a sensor operatively coupled to the motor and providing a signal corresponding to a rotational speed of the motor and a rotational position of the motor; a controller operatively coupled to the motor and the sensor, the controller regulating an amount of power provided to the motor responsive to the signal from the sensor in order to maintain the rotational speed of the motor at a substantially constant level; and a sound generator operatively coupled to the controller, the sound generator providing simulated train sound effects in correspondence with at least one of the rotational speed of the motor and the rotational position of the motor; wherein the controller is further adapted to receive at least one command signal from a remote control unit.
