ABSTRACT:
An improved crossing gate for railroad grade crossings. The gate is constructed of an impact-resistant material, and the crossing arm is mounted so that it will swing out of the way and return to its original position if struck by a moving vehicle from either direction. The crossing arm also contains protected lighting that will withstand impact, and provision is made to permit easy replacement of burned-out light bulbs.
