Patent number: 8001908Abstract: A model vehicle, such as a model electric train, includes a model automatic door. The operation of the door is automated using a motor, drive train, and control circuit. A drive mechanism moves the door between open and closed positions. In the open position, the door is displaced laterally along and displaced outwardly of the body of the train car to expose a door opening. In the closed position, the door is substantially flush with the body of the car and covers the door opening. The control circuit permits automatic operation of the door and provides various features for enhancing realism of the operating model.Type: GrantFiled: May 27, 2005Date of Patent: August 23, 2011Assignee: Lionel L.L.C.Inventors: Richard F.
