Abstract: A system and method is provided for directing smoke in a model train. In one embodiment of the present invention, the model train includes a smoke chamber physically connected to a smoke unit. The smoke unit functions to produce smoke, which is then provided to at least one smoke chamber. Each smoke chamber includes at least one exhaust opening and a valve for selectively moving smoke out of the exhaust opening(s). For example, the smoke chamber may include an intake opening, at least two exhaust openings, a piston core and a piston driven by a drive rod. By moving the drive rod, the piston can be moved through the piston core, resulting in the movement of smoke out of the exhaust openings. By positioning the exhaust openings near the wheels of the model train, the smoke system can be used to simulate steam escaping from valves or cylinders.

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.
