Abstract: A switch point position detecting system and method uses a plurality of proximity detectors positioned proximate the switch point or points of a railroad switch. Additional proximity detectors are placed within a switch machine housing to detect the position of components therein, such as lock rods and lock bars. One or more Programmable Logic Controllers (PLC's) have inputs connected to the proximity detectors and outputs connected to relays or switches which control the switch machine and signals. The PLC's are programmed to operate the relays to give signals to proceed only when correct indications are received from all effected proximity detectors.
