Abstract
Some methods include rotating a crossing gate actuator around a vertical swing pivot of a crossing gate mount, along a vertical swing path and into a down position to block a path such that a crossing gate coupled to the crossing gate actuator blocks the path, with a spring biased crossing gate release mechanism maintaining the crossing gate in a center position blocking the path and decoupling a bar segment from the crossing gate to decouple a spring from biasing the crossing gate into the center position such that the crossing gate is free to swing around a horizontal swing pivot, perpendicular to the vertical pivot, and out of the path.
