Abstract
A model vehicle, such as a model electric train, includes a motorized tilt mechanism for tilting train cars when traversing curved sections of track. The operation of the tilt mechanism is automated using a motor, drive train, and control circuit. A motorized tilt mechanism moves a train car body between left, right, and upright positions, depending on the direction and speed of movement of the model train. The control circuit permits automatic operation of the tilt mechanism in response to position and velocity input.
