ABSTRACT:
A system and method that enables trains to rapidly accelerate through grade crossings from station stops or civil speed restrictions is disclosed. In some embodiments, equipped trains and grade-crossing controllers communicate wirelessly to address operational limitations pertaining to the grade crossings. In conjunction with the train's equipment, conventional crossing controllers are augmented with a communications capability and logic to accept commands to operate in a “Prediction” mode or a “Motion-Sensing” mode. The Prediction mode is the default operating mode for conventional constant-warning grade-crossing prediction controllers. The Motion-Sensing mode is an operating mode whereby the crossing is actuated as soon as an approach circuit detects train motion.
