MOUNTING PLATE FOR FIXING ELASTOMERIC GRADE CROSSING PANELS TO TIES ABSTRACT 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 inter- connected 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 cross- ing element along the rails and prevents lifting of the free end of the terminal crossing panel.
