ABSTRACT:
A method and apparatus for directing the movement of a train around a model railroad track having one or more turn-outs activated by at least two separate arming signals. Each signal is linked to a specified direction of the turn-outs such as straight, curve right, or curve left. The arming signal is sent to all turn-outs on the railroad track but only the turn-out which the train is approaching is toggled to a position corresponding to the arming signal. All turn-outs over which the train is moving at the time the arming signal is sent are disarmed to prevent the train from derailing due to the toggling turn-out. Proximity-selection switches may also be used for slot-car operation or for city or highway vehicles which are part of a model or miniature diorama within the model railroad layout.
