Abstract:	This paper describes a GPS bas& remote hazard detection system that was designed and built for Providence & Worcester Railroad, Worcester MA. The system monitors the status of switches along a track from within a moving locomotive. GPS is used to triangulate and cross-reference the current position of the locomotive with a database of known switch locations. When a switch comes within two miles of the train its status is queried using a packet modem/transceiver combo. The switch status is posted to a display mounted in the train which alerts the engineer to potential problems with a switch.
