What Triggers A Railroad Crossing Light. The signals will activate around 30 seconds before the train reaches at most crossings. The covtec system uses a radar to detect a train and a wireless comms link between a remote detection unit and the crossing sounder. An incremental improvement is to provide a supplementary audible warning system, which detects an approaching train and provides an audible warning at the crossing. What causes a railroad crossing light to turn on? Red lights flash, a mechanical or electronic bell sounds, and usually a gate drops across oncoming lanes. How railroad crossing signals work. The basic signal consists of a mast with flashing red lights, a crossbuck, and a bell. The interconnect must trigger the traffic light preemption cycle sufficiently before the railroad crossing signals trigger to allow queues to clear off the track before the train arrives. A typical grade crossing features both visual and audible warning signals that a train is coming: When a westbound train approaches and enters the east approach circuit, the train shunts the rails (shorts them out) and this triggers a relay in the.
