ABSTRACT:
A railroad grade crossing comprising a plurality of elastomeric panels that are interconnected to provide integral multiple panel crossing units. Each panel has a plurality of elongate tapered cylindrical passageways extending through it that are parallel with the tracks being crossed. Pins are partially inserted into aligned passageways in adjacent panels to interconnect adjacent panels to one another. Because the passageways are tapered, and thus create larger openings at one end of the panels and smaller openings at the other ends, the pins are divided into larger ends, which fit into the larger openings, and smaller ends, which fit into the smaller openings. If it is desired to interconnect the panels into integrated crossing units prior to installation, the pins can be attached to the passageways and the ends of adjacent panels can be attached to one another with an adhesive. This permits the combined crossing units to be transported and installed as a unit. In this case attachment devices are placed integrally in the panels to facilitate lifting the crossing units with a crane. End restraints are attached to the ties at the ends of the crossing to prevent the crossing units from moving along the tracks.
