ABSTRACT:
Disclosed is a train proximity detector for detecting an RF carrier transmitted by a train, for a predefined period of time. Further, the encoded FSK data is decoded to determine if a match with a predefined data signature exists. If a match exists, visual and audio indications are provided to the operator, indicating a close proximity of a train. Modifications to train equipment can be made to cause the transmission of the carrier and FSK data on the activation of the train whistle, which is about 1500 feet from every crossing.
