Patent ID: 7307394

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 adapted to detect speed of the model train; a remote control interface adapted to receive at least one user command; a controller operatively coupled to the motor, the sensor and the remote control interface, the controller being responsive to the at least one user command in selecting a desired speed for the model train, the controller using the detected speed in a closed feedback loop to regulate an amount of power provided to the motor in order to propel the model train at the desired speed; and a sound generator operatively coupled to the controller, the sound generator adapted to generate a selected sound effect in correspondence with the detected speed; wherein the controller further includes a memory storing data to be accessed upon a loss of power to the model train.
