Abstract
A system and a method for inferring status of switches positioned along a route traveled by a vehicle system are recited. A switch indicator is to emit a first signal in response to each of the switches being in its alignment configuration. The first signal emitted from the switch indicator is received in response to the vehicle system traveling toward the switch indicator before arriving at an outmost switch. That each of the switches is in its alignment configuration is determined based on a clustered first group in response to receiving the first signal.
