Abstract: The roadway at a road-rail crossing comprises rows of extruded rubber strips. The strips have a tongue-and-groove type of edge connection, which constrain the strips such that if one strip bounces the adjacent strips bounce too. Locking-strips fit between primary-strips, and have latches, which snap into place upon the locking-strips being driven downwards, from above.

Abstract: At a crossing, rubber interface strips are positioned between the rails and the asphalt or concrete. A U-shaped spring-clip fits underneath the rail, and has upstanding arms that carry tappets, which engage the strips. One of the arms is threaded, and carries a screwed tappet-rod. Turning the tappet-rod closes the distance between the tappets, clamping the strips onto the sides of the rail, and forcing the springy arms apart. The spring-clips are manipulated into position while in an unstressed condition. The spring-clip is only brought up to force when finally assembled. Assembly can be done without tools, and with little danger of mix-assembly, or of injury to workers.

Abstract: Pre-cast concrete panels are commonly provided at road-rail crossings, to serve as the roadway, but such panels have been liable to premature failure. Rubber caps are placed over the cross-ties, between the panel and the ties, to isolate the panel from the stresses that arise when the panel contacts the ties directly. The caps are ribbed. Two kinds of ribs are provided, some solid and rectangular, others triangular and hollow. The ribbed panels provide resilience and hysteresis over a range of conditions, to prevent fretting and cracking of the panel.

Abstract: At a road/rail crossing, rubber inserts are located alongside the rails, between the rail and the asphalt of the road. The insert has a resilient nose, which engages the under-face of the head of the rail. The insert does not touch the web of the rail, but rather the insert is wedged between the head and the flange of the rail. This engagement assists in locking the insert to the rail, by self-locking-taper action.
