Abstract: A rail brace assembly is adapted to buttress the head of a stock rail selected from one of two different stock rail groups mounted on the top surface of a brace plate. The assembly includes a stop block assembly also is affixed to the brace plate top surface. A rail brace moveable between a first brace position in which it buttresses the head of a rail from a first stock rail group and a second brace position in which it buttresses the head of a rail from a second stock rail group, has a pair of spaced side walls, a upwardly facing top surface, first rail group head and base fishing surface contact areas, second rail group head and base fishing surface contact areas, a first rail group brace plate contact surface and a second rail group brace plate contact surface. An elastic fastener cooperates with a clip housing to clamp the rail brace against the stock rail.

Abstract: A substantially M-shaped rail clip is disclosed in which the clip is substantially flat when in its non-operative configuration, and, when the clip is in an operative configuration, the toe of the clip lies substantially in a second plane and the legs of the clip lie substantially in a third plane, the second and third planes being non-parallel to one another.

Abstract: A rail fastening system for fastening a rail to a rail support includes a frame member supported by the rail support and including an upper bracing portion positioned above the rail support to define therebetween a space. A stationary insulator member is positioned at a fixed location on the rail support. A plate-shaped spring blade has a first end resting on the stationary insulator member and an opposite second end supported by a movable insulator member. A wedge member is connected to the spring blade and is operable to be inserted into the space, thereby inserting the spring blade into the space with the first end of the spring blade being supported and sliding on the stationary insulator member and with the second end of the spring blade being supported on and moving the movable insulator member in the insertion direction.

Abstract: A rail-tie fastening assembly for fastening a rail to a concrete tie comprising a rail seat assembly and a rail anchor. The rail seat assembly includes a rail seat basin and a rail seat wherein the rail seat is disposed in the rail seat basin and bonded thereto with an elastomeric material having a void formed therein between the bottom of the rail seat and the bottom of the rail seat basin so as to produce a shear spring which transfers applied vertical load from the rail to the tie. The rail seat assembly is embedded in the tie and the rail anchor is adapted to engage a portion of the rail and to interlock with the rail seat assembly so as to cooperate with the rail seat assembly to fasten the rail to the tie.

Abstract: In a device for mounting in position guide rails (1), in which device the guide rail (1) is free of perforations and is seized by claws (3), which claws (3) are fixed in a mounting part, the mounting part has a mounting plate (2) extending in parallel relation to the longitudinal direction of the guide rail, noting that the claws (3) can be passed through perforations (16) in the mounting plate and can be braced against the mounting plate (2), in particular with the interposition of a spring (4), at the side, located opposite the guide rail (1), of the mounting plate (2).

Abstract: A resilient rail fastener having a clip having a lower leg with a toe at one end and a heel at the other, an upstanding back portion between the heel and an upper leg, and a rectangular locating aperture in at least one of its legs which engages over a rectangular retaining block. The retaining block has pressure imparting means projecting from each side and bearing downwardly on the upper leg of the clip and thereby applies a downward pressure at each end of the lower leg. One end of the lower leg bears downwardly on the rail support and the other end on the rail to impart a toe pressure. The reduced cross-sectional area of the clip where it passes over the retaining block causes high stresses in the legs of the clip as well as at the locality of the clip heel, and the upstanding back portion has less stress than a hairpin clip, and this results in a lower spring rate for the toe clip so that toe pressure is retained upon rail settlement, and stress corrosion is reduced.
