Abstract: A system and method is provided for selectively directing smoke in a model train or other model vehicle. In one embodiment, a directional fan is used to guide smoke to one of at least two output ports. When the fan is rotated in a first direction, air is drawn in through a first port and smoke is directed out of a second port. When the fan is reversed, the flow of air is reversed to draw air in through the second port and to direct smoke out through the first port. In another embodiment, multiple blower units are connected to a common smoke generating unit and can be selectively operated to direct smoke to plural locations within a model vehicle. The volume an speed of smoke can be variably controlled, and audio effects can be synchronized with smoke visual effects for added realism.

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.
