  • Patent number: 4919330
    Abstract: The railroad highway crossing panel fastening system includes a series of dowel pins, spring clips and hanger/hanger bars. The dowel pins are inserted or cast into the ends of each crossing panel in a plane parallel to the base of the rail and are positioned from the edge and top of the panels in such a manner as to accomodate varying rail sections. Each dowel pin protrudes beyond the end of the panel a sufficient distance so that when the spring clips or hangers are attached to them and engaged they secure the crossing panels to the track structure enabling highway traffic to pass over the railroad tracks in a safe manner.
