A railroad grade crossing system comprises a plurality of plates that rest on selected ties. The plates have two or more upstanding projections with threaded openings extending through them. The plates are positioned at the intersections of adjacent elastomeric grade crossing panels that have recesses defined in their lower surfaces that receive the projections. Bores extending through the panels coaxially with the recesses permit bolts to be installed through the panels into threaded engagement with the projections. Since adjacent panels are attached to a common plate, they become interconnected so that the weight of an entire crossing element will resist movement of the panels. In a typical application there are three crossing elements; a gauge element between the rails, and a field crossing element between each rail and the adjacent roadway. Typically, the gauge panels only extend half-way between the rails so that each gauge plate is coupled to the inner corner of four adjacent gauge panels. A locking panel, having wings which fit over the tie, is located at the center of each crossing element to facilitate installation. An end restraint, affixed to a tie at each end of each crossing element, ensures that there is no movement of the crossing element along the rails and prevents lifting of the free end of the terminal crossing panel.

A system for mounting a railroad grade crossing, of the type where a plurality of side-by-side elastomeric field panels are located between each rail and the edge of the roadway that crosses the rails and a plurality of side-by-side elastomeric gauge panels are located between the rails, without penetrating the ties that support the rails, said panels having a lower surface that rests on the ties and an upper surface that supports vehicles passing over the grade crossing, said system comprising: (a) a plurality of plates that rest on selected ties and have upwardly-extending projections; (b) means associated with said projections for threadedly receiving bolts; (c) the panels having openings extending therethrough, the portions of said openings adjacent to the lower surfaces of the panels defining recesses that matingly receive said projections, and the portions of said openings adjacent to the upper surfaces of the panels defining counterbores; (d) bolts that extend through said openings into threaded engagement with said engagement means in said projections, said bolts having heads that fit within said counterbores below said upper surfaces of the panels; wherein (e) each of said plates contains projections that mate with recesses in two or more side-by-side panels.
