BROKEN RAIL DETECTION BY ACOUSTIC GUIDED WAVES FOR COMMUNICATION BASED TRAIN CONTROL

The paper describes the new Advanced Automated Train Control (AATC) Communication Based Train Control (CBTC) system that has been developed by the San Francisco Bay Area Transit District (BART). The system uses radio ranging to locate and communicate with trains. The system is based on the principle that guided acoustic waves with rail have little attenuation and thus travel long distances; it is assumed that the occurrence of a break will interrupt the acoustic path between a transmitter and receiver causing a loss of signal.
