The profiled bearing has a profiled base with a first lateral wall, a second lateral wall, and a base which connects a first end of the first lateral wall to a first end of the second lateral wall, and the profiled bearing also has a profiled clamping section. The base and the lateral walls form a receiving pocket for receiving the rail. In a functional position, the profiled clamping section is clamped in a gap between the rail inserted into a bearing bed of the base and the second lateral wall.

Abstract: The invention relates to an interface pad comprising a stiffener supporting a resilient pad to cushion the panels in a grade crossing between and around the rails from impact with the underlying ties and to prevent the panels from moving. The pad may be flat or a cupped shape and may be of varying size to accommodate varying tie widths. The invention further comprises means to securely fasten such an interface pad to a railroad tie and minimize the possibility that the interface pad will be forcibly removed from the tie during installation of the rails or panels in the grade crossing.

Abstract: A rail support block assembly includes a resilient member and a molded block having a top, a bottom and peripheral wall. The block is adapted for fastening one or more rails on the top. The prefabricated resilient member has an outer tray and inner tray arranged within the outer tray, and includes a resilient intermediate structure between the trays. The block is molded. The block is fixed in the inner tray to extend under the bottom of the block and along a lower region of the peripheral wall. The resilient member may form a part of the block mold, so that a mold member combined with the resilient member delimit the mold for the block. The moldable material is introduced and adheres directly to the inner tray of the prefabricated resilient member.

Abstract: A rail seal for sealing the gap between a rail and the surrounding surface material in a rail crossing or track construction, wherein the rail seal is removable from the gap and can be re-installed in the gap without damaging the surrounding surface material. More particularly, the rail seal is formed with an integral hinge element that has a closed position and an open position wherein an upper portion of the rail seal is released from and extends upwardly away from a lower portion of the seal body thereby imparting additional flexibility to the seal body. To remove the rail seal from the gap adjacent the rail, the rail seal can be manipulated so as to be pulled free from the gap. In order to re-install the rail seal, the additional flexibility provided by the hinge element allows the rail seal to be manipulated and deformed as required so as to be re-installed within the open gap.

Abstract: A rail seal for sealing the gap between a rail and a concrete panel in a railroad crossing so as to provide a generally even or level surface for vehicular or pedestrian traffic while still providing an appropriate rail structure for receiving and guiding the train wheels along the tracks is provided. More particularly, the upper surface of the rail seal is formed with a recessed portion or flangeway for receiving the flanged-end of a train. The flangeway or recessed portion, however, is formed so that the surface of the flangeway lies in a plane above the bottom of the rail head but below the upper surface of the rail head, thereby providing a “shallow” flangeway. The provision of a “shallow” flangeway helps to reduce the risks associated with vehicular and/or other pedestrian traffic that must access or cross the railroad tracks.

Abstract: A system for embedding a pair of rails of a railway track comprises a pair of field panels adapted for positioning opposite each other at outer sides of the rails and a gauge panel adapted for positioning between the rails. Each field panel has a side surface adapted to face its corresponding rail outer side and the gauge panel has opposite side surfaces adapted to face the inner sides of the rails. A first filler strip is associated with each of the field panels and a pair of second filler strips are associated with the gauge panel. Each of the first and second filler strips include a sealing portion that is adapted to contact one of the inner and outer rail sides and a mounting portion for connecting the filler strip to its respective panel. A U-shaped reinforcing member extends along a length of each filler strip mounting portion such that each filler strip is sandwiched between its respective reinforcing member and panel side surface.

Abstract: In a track whose rails are laterally and downwardly supported on the rail outer side and on the rail inner side via elastic intermediate inserts (4, 6) by longitudinal carriers underneath the head portion (3), the rails (2) extend at a distance above the track structure parts located therebelow. The longitudinal carriers at the rail outer side are first console ledges (5) which are part of a base plate (10) lying under the rails (2), and the longitudinal carriers on the rail inner side are second console ledges (7) which are part of an inner plate (11) lying between the rails (2), which inner plate (11) in turn is supported on the base plate (10).

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: A track rail having a groove for flanges of rail vehicle track wheels in an upper surface of the rail and having a central bar portion and flanges extending integrally sideways from the top of the bar portion is inserted in a recess preformed in the roadway with clearance so the rail is supported from the roadway's surface by the flanges. The rail is shallow so the recess is only shollowly preformed in the roadway. If the roadway has insufficient load-bearing capacity it is possible to reinforce the roadway by a concrete beam around 30 centimeters wide and 10 centimeters deep grouted with concrete in the road surface; this again is shallow for rail tracks. This beam would be recessed to receive the rail as above and also to receive the flanges.

Abstract: A concrete-embedded, machinery-anchoring floor system includes parallel, accurately-extruded steel rails each having a unique cross-sectional configuration. Vertical loading of the rails improves the load-bearing strength of the concrete, whether the loading is in tension or compression. Each rail includes a pair of spaced angularly-extending, outwardly and downwardly-projecting flanges. When a downward compressive load is applied through the rails from above, the load also applies downward and inward force vectors generally perpendicular to the angular flanges, compressing concrete therebetween. If tension is applied to a rail from a cantilevered load, the angular flanges are fulcrumed toward each other about their connecting joints with the rail, also compressing and strengthening concrete therebetween. The angular flanges are rounded at their distal edges to enable supporting and interconnecting reinforcing bars to be easily welded to the rounded edges, irrespective of the angle of the bars to the edges.

Abstract: The method relates to the laying of rails in a trench into which concrete is subsequently poured in order to fasten the rails. The method consists in laying adjustable-length ties (4) on the bottom of the trench (3), in roughly positioning the rails (14, 15) by means of block-supports, in fastening the ties to the rails by using tie-screws (10) and anchor sleeves (11) as bolts and nuts, in adjusting the length of the ties and in leveling the ties by means of auxiliary screws (18), and then in pouring the concrete, the auxiliary screws being subsequently removed. The ties are preferably pre-equipped with tie-screws, with sleeves and with rail-fastening clamps and the tie-screws and the sleeves may also be used for fastening tie-plates to the ties.

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.

Abstract: A railroad grade crossing structure comprising a plurality of prefabricated, elongated, reinforced concrete panels formed of used, inverted rail sections placed between the rails of each track and outside the rails of each track to provide a smooth durable highway surface; the panels resting on resilient pads supported on elongated crossties containing upstanding studs to fit loosely within sleeves in the bottom of the panels to prevent undue lateral movement; substantially all free space between panels and the rails of each track being filled with a settable elastomeric compound; the end panels adjacent the shoulders of the highway having an upper surface substantially flush with the highway surface and sloping downwardly to the lower surface of the panel which rest on the resilient pads.

Abstract: A crossing construction for a railway including a plurality of spaced-apart cross-ties that support two parallel rails positioned thereon. The crossing includes a center pad of resilient rubber-like material positioned between the rails. A side pad of resilient rubber-like material is positioned on each side of the railway. Shims are used to position the uppermost surfaces of the center and side pads flush with the tops of the rails. On each side edge of the crossing there is provided a cap of resilient rubber-like material that includes a first leg that extends horizontally under a portion of each side pad and a second leg that extends vertically downwardly and covers the ends of the shims and a portion of the ends of the cross-ties the cap may include an extension pad and an L-shaped reinforcing member.

Abstract: A module for cooperative installation with a plurality of similar modules proximate a set of railway tracks, and borne upon support members therefor to yield a modularized railway crossing grade assembly, is comprised of a hollow form having exterior side walls, end walls and a bottom wall, a keyway formed in a first end wall and a key formed in the opposing end wall, the keyway and key being of complementary geometrical configuration whereby successive forms may be positively interlocked, and anchoring members for securing the form to a support member. The module is adapted to receive a quantity of load-bearing fill material within the hollow form.

Abstract: The exposed ends of railroad grade crossing platforms are protectively capped with elongate devices which provide ramps sloping downwardly and away from the surface of the platforms along the ends of the grade crossing. The ramps deflect air hoses, chains, etc. which occasionally hang downwardly from railroad cars and locomotives passing over the grade crossing, and, thus, prevent the free ends of such items from being caught on or damaged by the otherwise exposed ends of the grade crossing platforms. Ramp-supporting members extend in mutually spaced relationship from the underside of the ramp of each device so that in end view, the device has the shape of essentially a right triangle, whose hypotenuse is on the ramp surface and whose legs are partially formed by the respective supporting members and partially by the ramp. The opposite legs of the triangular shape are preferably unequal in length so that the cap devices can accommodate two different platform heights.
