Abstract: In a switch including a switch frog (1) with a movable frog point (2) and wing rails (5, 6), wherein the wing rails (5, 6) in the region of the frog point (2) each have a rail profile which is lower than that of a standard rail, the wing rails (5, 6) are designed as Vignol rails whose region configured with a lower rail profile is produced by metal-forming departing from the Vignol rail profile.

Abstract: Fastening for a rail and arrangement for fastening of rails The invention relates to a fastening for a rail for securing a rail (10) whose foot is resting on a concrete sleeper (16), comprising at least one elastic clip (20) having several legs of which at least one leg extends inside a shoulder (42, 44) or channel of a holder (24) that is connected to the concrete sleeper, and at least one further leg rests on the rail foot. For securing a rail to the necessary extent with simple design means and in space-saving form, it is suggested that the holder (24, 26) is arranged detachably in the concrete sleeper (16) or in a plate element resting thereon and is connected to the concrete sleeper by a bolt element.

Abstract: A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip.

Abstract: A rail fixing device including a tensioning clamp extending from a holding element and removably arranged on a ribbed plate on which the rail base is mounted. The ribbed plate is placed on an elastic intermediate layer which is maintained in a required prestressed state by the holding element.

Abstract: In a device for lifting a tongue rail (3) of a switch during switching of the tongue rail (3), including a roller holder (8) for rollers or rolls (14), which is arranged laterally outside a slide chair within the surface of a sleeper (18) facing the rails (3,5), the roller holder (8) is connected with a flange (9) carrying a stop bar (11) for fixation to the rib plate (1), and the stop bar (11) laterally bears against an edge of the rib plate (1) in the position connected with the rib plate (1).

Abstract: A rail fastening apparatus for fastening an inner stock rail (2) in a railway slide chair assembly comprises a baseplate (100) having on one face thereof a rail seat region (110) on which the inner stock rail (2) sits when the slide chair assembly is in use, a resilient rail fastening clip (7) for restraining such an inner stock rail (2), the clip (7) comprising an elongate member having at one end a toe portion (71) for bearing on the rail (2), locating means (101, 102) for locating the rail fastening clip (7), which locating means (101, 102) are positioned on the baseplate (100) in a second region (120) spaced from the rail seat region (110), the clip (7) having at its other end a heel portion (72) for engaging the locating, means (101, 102), and the locating means (101, 102) comprising an abutment portion (101a) against which the heel portion (72) of the clip (7) abuts when the apparatus is in use to inhibit withdrawal of the clip (7) from the rail (2), and loading means (9) for vertically deflecting the c

Abstract: In a method for connecting switch or crossing parts made of austenitic manganese steel casting, or austenitic manganese steel rails, with rails of carbon steel, the parts to be connected, optionally upon interposition of an intermediate piece, are connected by friction welding, wherein the weld with the austenitic manganese steel is cooled at static air without heat treatment.

Abstract: In a device for securing stock rails in railway switches comprising a bearing plate (2) for the stock rail (1), a slide chair (3) for the switch blade and an elongate spring element (6) for holding down the rail foot (1), the spring element (6) is insertable into a tunnel-shaped recess (5) of the slide chair (3) at a tension insufficient for holding down the rail foot (1), or without any tension at all, and is braceable relative to the rail foot (1) and the bearing plate (2) by a separate clamping wedge (10) extending transverse to the spring element (6). The spring element (6) has a cross section varying over its length and, starting from a central region in which it cooperates with the transverse wedge (10), tapers towards its two free ends and, on its free end (9) facing away from the rail foot (1), is designed to project towards the bearing plate (2).

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).
