A railroad highway crossing signal electronic assembly for use on bi-directional tracks, where a control unit sends AC voltage to an approaching rail segment wherein a rectifier receives AV voltage and discharges DC voltage which is sent back to a relay which controls lights on a gate arm. There is also a separate high current DC output to tracks. When shorted, the high current DC output creates sparks to improve detection of a train.
