Abstract: A clip for securing a rail seal element to a rail includes a generally L-shaped first clip member having a clamping arm and an elongate connector arm extending from one end of the clamping arm and capable of passing under the rail; a second clip member removably slidable on the connector arm; and a locking mechanism capable of releasably locking the second clip member against sliding movement along the connector arm. In use, the second clip member is removed from the connector arm so that the connector arm can be passed under the rail with minimum disruption of the ballast. The second clip member is then slid back onto the connector arm, and the assembled clip then oriented so that the rail and the rail seal are positioned between the damping arm and the second clip member. The second clip member is then slid on the connector arm toward the clamping arm so as to tightly press the rail and rail seal therebetween.

Abstract: A structural arrangement for an embedded and sealed railroad track and a method for its installation to provide a gutter defined along the rails of such a railroad track extending along or across a street or highway with rail tops at pavement level. Rubber filler bodies are held in place along the sides of each rail by retainer strips which lock into place on the filler bodies. A retainer form holds the filler bodies in place and provides space for the retainer strips when pavement materials are cast in place along the rails. Protective caps and sealing structures are installed before pavement materials are cast in place, to exclude the paving materials from space needed as a gutter along the rails to provide access to the rails and to spaced-apart supporting structures to which the rails are fastened, and to keep foreign materials from getting on the top of the rails and prevent them from becoming caught between the rails and the adjacent filler bodies.

Abstract: Sections of a highway crossing over the rail road are raised completely clear of the rail road to form a barrier preventing automobile traffic from entering the rail road when a train is at or nearing the crossing. When the train has passed, the barrier sections are lowered, reforming the grade crossing so that automobile traffic may cross the rail road at near grade. The ends of each barrier transverse to the centerline of the roadway are shaped and positioned so that a continuous surface is formed when the barrier sections are in the lowered position, partly resting on the rail road or nearby supports, allowing automobiles to continue over the rail road by means of driving on the upper surfaces of the lowered barriers, with only small gaps at the joints where the sections adjoin each other or meet the approach roadway.

Abstract: Assemblies of resilient moldings are used as track crossings. A molding has a rubber surface layer which is bonded to a body formed from scrap rubber. In forming the molding, granular vulcanized rubber is mixed with a binder including crude rubber and a vulcanizing agent. The mixture is placed in a mold together with a crude rubber layer which also includes a vulcanizing agent. The molding is formed upon vulcanizing under heat and pressure.

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 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.

Abstract: A precast concrete grade crossing includes a plurality of base members, each of which has a central recess formed in the upper surface thereof. A pair of rails are each encased by a rubber boot which extends through the crossing in a single continuous piece. The boot-encased members are received in the recess which includes a shoulder along the outer side of each rail. The shoulder bears against a lip of the boot which extends upwardly to along outer side of the head of the rail to prevent moisture from entering the space between the boot and the rail below the shoulder.

Each of the second paving plates has a projection provided at one side thereof near the respective rail and engaged with the rail.

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.

Abstract: 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.

Abstract: A plurality of timbers connected to ties at a railroad grade crossing. Hooks are connected to some of the ties. When the timbers are disposed on the ties, the hooks are inserted into the timbers. Pins are disposed through the ties and through portions of the hooks for connecting the timbers to some of the ties. The timbers are connected in groups of two or three timbers to form field deck panels and gauge deck panels.

Abstract: The railroad highway crossing panel fastening system includes a series of dowel pins, spring clips and hanger/hanger bars. The dowel pins are inserted or cast into the ends of each crossing panel in a plane parallel to the base of the rail and are positioned from the edge and top of the panels in such a manner as to accomodate varying rail sections. Each dowel pin protrudes beyond the end of the panel a sufficient distance so that when the spring clips or hangers are attached to them and engaged they secure the crossing panels to the track structure enabling highway traffic to pass over the railroad tracks in a safe manner.

Abstract: An improved highway grade crossing for railroad tracks. The crossing is comprised of a plurality of wood panels which are capped with an expanded polymer. The polymer provides a wear surface for the crossing which can be replaced without having to take up the entire crossing structure. In one embodiment the polymer cap is a rubber and steel composite. The steel keeps the rubber stretched to substantially avoid temperature induced expansion and buckling of the rubber. Deterioration resulting from vehicular traffic over a buckled surface is thus avoided.
