Abstract
A rail line sensing and safety system adapted to reliably sense the presence, and optionally the direction and speed, of vehicles traveling on a rail line, and when a vehicle is sensed, to indicate whether a safety device, such as crossing gates, lights, bells, etc., should be activated. The system comprises at least one detection module typically mounted on a rail, at least one remote module typically located near a detection module, and at least one control module typically located near a safety device. In operation, a detection module senses a vehicle traveling on a rail line and sends signals to a remote module. The remote module then processes signals received from the detection module and transmits signals to the control module. The control module then directs, either directly or indirectly as a backup or supplement to an existing sensing and safety system, whether a safety device should be activated.
