Abstract
A system and method is provided for controlling bell movement and/or sound in a model train or other model vehicle. In one embodiment of the present invention, the system includes a user control, a sound subsystem, a bell controller and a bell device. The user control may include a lever, a track, and a plurality of predetermined positions on the track, wherein the lever can be moved by a user to any one of the plurality of predetermined positions. The user control may be configured to transmit at least one bell signal in response to the lever being released from (or moved to) one of the plurality of predetermined positions. The bell controller is configured to receive the bell signal, and to use the bell signal to control at least the bell device. The bell device may include a bell and an electromagnetic device, wherein the bell comprises a permanent magnet and is configured to swing from a bracket. By applying at least one voltage to the electromagnetic device, and placing the bell near the electromagnetic device, a magnetic field can be created and used to swing the bell from the bracket, thereby simulating bell movement. The bell controller may further be adapted to synchronize bell movement with bell sound by transmitting a bell sound signal to the sound subsystem at a particular time, so as to substantially synchronize at least one bell movement with at least one bell sound.
