摘要： A railroad grade crossing system includes an integral concrete pad that has a pair of spaced-apart cavities located in its upper surface. The cavities have planar bottom surfaces that support rails with their heads flush with the top surface of the pad. The cavities have outer side walls that conform to the shape of the rails. The rails are placed in the cavities against the outer side walls and are secured in place by a rail anchor system. The remainder of the cavities are filled with elastomeric liners that have outer side walls that are shaped to conform to the shape of the rails. The inserts are held in place in the cavities by frictional engagement between bulbous gripping heads, secured to anchors located in the pads, that frictionally interfit into conforming holes located in the inserts.

摘要： 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.

摘要： A grade crossing system for extending a roadway across a railroad track comprises elongate elastomeric pad units which abut each side of the rails in the track but do not extend across the entire crossing. The elastomeric pad units rest on the ties that carry the rails and have planar top surfaces that are coplanar with the tops of the rails. The remainder of the crossing is filled with non-elastomeric panels that also rest on the ties and have planar top surfaces that are coplanar with the top surface of the rails. The abutting edges of the pad units and the panels overlap such that the panels hold the pad units down against the ties and urge them against the sidewalls of the rail flanges. Thus, mechanical fasteners are not required to hold the crossing elements in place.
