Abstract: A method and apparatus for detecting the actual and true position of model railroad turnout points while not adding any load or hindrance to the turnout points or to said points operating mechanism. The movable, tapered rails of railroad turnouts are called points, and their position determines the route that the train will follow. Using Hall-effect switches and magnets, the actual and true position of the turnout throw bar and points is detected without any physical contact with the throw bar, the points, or with the mechanism that actuate said throw bar and points. The output of the Hall-effect switches is used to communicate and provide feedback of the actual position of the points to the position display indicators, which are observed by the model railroad operator, and to the model railroad control system.
