  • Sonic track condition determination system
    Patent number: 4932618
    Abstract: Sonic transponders mounted on a train and the track upon which it rolls transmit and receive sonic vibrations along the track. Information currently being transmitted electrically may also be thus transmitted sonically. Since the track interferes with the sonic vibration more than it does with an electrical signal, the condition of the track may also be determined.
