Model Railroad Car Position Indicator
US Patent:

Filed:
Dec 5, 1995
Appl. No.:
8/567472
Inventors:

Abstract:
A model railroad car position indicator includes a sensor receptive to the presence of a model railroad car on a track. Control circuitry determines the location of the car relative to a predetermined position on the track and approves initiation of a model train process if the car is within a range of acceptable positions for initiating the process. A preferred embodiment includes circuitry for determining whether the car velocity is less than a predetermined threshold velocity. In this embodiment, approval of initiation of the model train process is conditioned on both the car position being acceptable and the car velocity being acceptable. An indicator provides feedback to the model train operator for manual initiation of the model train process. Alternatively, the control circuit may automatically initiate the process.
