Abstract
A railroad crossing gate assembly includes a gate arm adapter, which is pivotally mounted to allow a lowered gate arm to rotate in response to a generally perpendicular force in a generally horizontal plane either toward or away from a railroad crossing. The gate arm mechanism further includes multiple interchangeable spring assemblies that generate a return force to bring a displaced gate arm back to its normal operating position, and at least two latch hook assemblies for selectively latching the gate arm in its normal position and controlling the rate of return of the gate arm from a displaced position through application of a pivotally leveraged force to a braking surface of the adapter.
