Circuitron 800-5202 DT-2 Grade Crossing Detection Unit N UniTrack Hand Taps are the versatileCircuitron 800 5202 DT 2 Grade Crossing Detection Unit Specifically deigned for use at grade crossings, using Opto Sensors to detect the train. Output controls flasher, gates, bells, etc. Full logic system duplicates prototype grade crossing action. Does not require sensor stay covered to activate. Integrated memory keeps output "on" until last car clears the crossing. Activates whenever a train approaches from either direction, If trains stop short
