ABSTRACT:
A railroad in-cab signaling system which includes transceivers disposed at signals where various transceivers are operating on different frequencies and addresses so as to provide for easy identification and highly secure communication to the signal transceiver and a tunable transceiver disposed on the locomotive, the locomotive transceiver being coupled to an interrogator which interrogates transponders disposed in the tracks, the transponders providing a message containing the predetermined frequency and address of the signal transceiver thereby allowing the locomotive transceiver to tune to the appropriate frequency and established a connection for the signal which it is approaching. The locomotive transceiver and the signal transceiver are then capable of exchanging information along the entire distance from the transponder to the signal.
