Abstract: The invention relates to a superstructure points device, in particular intended for a grooved rail, comprising a box-like substructure (32) with stock rail (14), if necessary an additional/supporting rail (16) and slide plate (18) on which a tongue rail (20) is slidably mounted. In order to mount the rails of the points device elastically, while also allowing the option of simple removal from the rail/road bed, it is proposed that the box-like substructure (32) is mounted elastically in a stationarily arranged frame (38) of the points device.

Abstract: A superstructure arrangement for a track comprising a rail fastened to a securing device such as a ribbed plate which is disposed above a concrete sleeper, with an intermediate layer extending between the sleeper and the securing device. The rigidity of the intermediate layer is variable and rated so that at the maximum permissible stress in the rail, caused by bending under wheel lead, the elastic property changes to substantially non-elastic.

Abstract: The invention relates to a track with rail track section (10) which differs from the usual basic layout. In order to check changes in track layout in a simple manner, the invention provides that the rail track section (10) has a cutout (24) running parallel to the basic layout in a longitudinal direction of the track. When the rail track section is placed parallel to the basic layout, the layout of said cutout is inversely the same as that of the desired change in layout.

Abstract: A process for manufacture of a railroad track part, in particular a large points part, with rail parts such as a frog point and connecting rails, and the track part obtained. The track part is made of materials of differing composition, one of which is a carbon steel and one of which is an austenitic manganese steel, which are connected by welding and are subsequently subjected to a joint heat treatment. To permit joining of the materials without negative effects on their properties, the parts are joined directly by electron beam welding or indirectly via an intermediate layer comprising a nickel-based alloy, the joined parts then being heated to a temperature T and held over a time t such that for the austenitic manganese steel, solution annealing takes place, and for the carbon steel, austenitizing takes place.

Abstract: An expansion joint for part of a railway track arranged on a foundation has a stock rail with a stock rail head and a tongue movable with respect to and along said stock rail head, upon which at least one fastening device acys for pressing it on the stock rail. This expansion joint enables the rail foot to be lingitudinally moved with little friction and excludes tipping of the stock rail or tongue. For that purpose, the tongue is not bolted, but pressed only against the stock rail by the fastening device, and the force thus transmitted is decomposed into components that act, on the other hand, in the direction of the foundation and, on the other hand, in the direction of the stock rail head. The force is transmitted by a rolling element extending from a shaft which is anchored to the foundation.

Abstract: A method and device for the elastic bending of a support (16) with at least one bendable end (24), intended in particular for a flexible switch (10). To achieve an elastic line of a finite radius of curvature also at the free end of the support, a bending moment diverging from zero is generated in the elastically bendable end (24) of the support (14) by applying a force coupling to an auxiliary lever (28).

Abstract: A superstructure arrangement for a track comprising a rail fastened to a securing device such as a ribbed plate which is disposed above a concrete sleeper, with an intermediate layer extending between the sleeper and the securing device. The rigidity of the intermediate layer is variable and rated so that at the maximum permissible stress in the rail, caused by bending under wheel lead, the elastic property changes to substantially non-elastic.

Abstract: The invention relates to a rail line, in particular for a high-speed magnetic train, comprising supports (10) constituting the rail line, which are placed on girders (12, 14) originating on opposite sides (34, 36) of the support and assigned to it in pairs and rest on the ground (16) or a foundation. To achieve an orientation of the rail line in the desired amount, it has been proposed that the girders (12, 14), which are assigned in pairs to each other, have a distance at the ground which is less than that at the supporting end, wherein the girders, controlled to the necessary extent, are adjustable in a plane extending vertically in respect to the linear axis of the rail line (18) in such a way that the rail line extends inclined in respect to the horizontal line.

Abstract: A bearing system for a part of a railroad track, such as a rail-fastening or ribbed slab (10), supported by elastic elements on, for example, a railroad sleeper. The elastic elements form a spring system with a kinked characteristic curve such that when the spring system is subjected to force that is smaller than the forces active in the operative range (16) of the spring system, the characteristic curve rises steeply and, in the operative range (16), runs flat.

Abstract: A support system for a rail section which bridges the gap between foundations which are relatively movable auxiliary rails running parallel to the rail across the sleepers which are supported by the foundation, and underpinning supports providing a stiff connection between rail and auxiliary rails. The underpinning supports move in response to relative movement of the foundation so that undesirable rail bending is avoided.

Abstract: An expansion joint for part of a railway track arranged on a foundation has a stock rail with a stock rail head and a tongue movable with respect to and along said stock rail head, upon which at least one fastening device acts for pressing it on the stock rail. This expansion joint enables the rail foot to be longitudinally moved with little friction and excludes tipping of the stock rail or tongue. For that purpose, the tongue is not bolted but pressed only against the stock rail by the fastening device, and the force thus transmitted is decomposed into components that act on the one hand in the direction of the foundation and on the other hand in the direction of the stock rail head.

Abstract: A rail junction (20) between rail lines (12, 14) extending in a direction parallel to each other for a car with a predetermined clear space profile, for a dual-track line of a high-speed magnetic train. Rail line (12) consists of line up supports (22, 24) and flexible support (16), rail line (14)consists of supports (28, 26) and flexible support (18), the flexible supports (16, 18) are elastically bent so that their ends (30, 32) are aligned for providing a rail connection. In order to permit a track change without changing the distance between the rail lines, the support (22, 26) adjoining the elastically bendable end (30, 32) of the bendable support (16, 18) is elastically bent outward away from the direction of the rails.

Abstract: Rail construction including laterally adjacent frog sections with guard rails outwardly spaced to each side thereof by interposed liners. The components are interconnected by a transverse tightened bolt with vertical misalignment precluded by either nesting projections on adjacent abutting faces of the components or by a rigid, preformed sleeve press-fit within the bore receiving the bolt, the sleeve extending through the frog sections and at least partially through the liners.

Abstract: A railway-track element is disclosed not only for normal track but also for rail points. The track element is formed of vacuum-treated steel containing at least 0.53 to 0.62% C, 0.65 to 1.1% Mn, 0.8 to 1.3% Cr, 0.05 to 0.11% Mo, 0.05 to 0.11% V and .ltoreq.0.02% P, the balance being iron plus the usual production-related impurities. The track element is in the form of a rail made of rolled pearlitic steel. If the track element is to be used for points, the starting material is a length of rolled rail with a martensitic structure produced by heat treatment at least in the rail head area.

Abstract: A railway tongue and junction rail assembly including a mounting fixed to the junction rail. The tongue abuts the junction rail at an inclined junction and is releasably secured within the mounting with the mounting being the sole means of joining the tongue to the junction rail.

Abstract: A roller assembly for a rail switch tongue used with a stock rail exhibiting reduced friction and resistance to vibration includes roller elements for supporting the switch tongue. Each roller element is supported by elastomer springs, one having a damping and the other having a supporting characteristic. The spring elements are mechanically coupled so that loading of the roller elements by the switch tongue causes a change in the spring length.

Abstract: To achieve low wear and hence a greater shape durability of track parts, it is proposed that the contact surface of a track part have a curvature having a constant difference .DELTA.K in relation to the curvature of the corresponding current contact surface of the wheel supported on it, or that successive contact surfaces of the track part and the wheel have a continually changing curvature difference .DELTA.K with the curvature difference between the contact surfaces of the track part and wheel lessening as the angle of contact tangent increases.

Abstract: A device for locking a switch blade with a stock rail which includes a locking piece connected to the stock rail. The locking piece has an opening through which the longer leg of an L-shaped locking clamp extends. A switch element also extends through the opening and has an upper surface in contact with the longer leg of the L-shaped member which extends below the foot of the switch blade. The shorter leg has an end free to articulate with respect to a shaft. The shaft is further connected with a clamp receiver or clamp notch. The pivot axis of the clamp receiver member and shorter leg extends parallel with the switch blade and is positioned above the foot of the switch rail such that the clamp receiver member slopes downwardly between the shaft and connection point with the switch blade.

Abstract: A device for locking a switch blade (10, 12) with a stock rail (14, 16) is proposed, whereby the switch blade is held down on a supporting surface only when it is in locked and unlocked positions. When the switch blade (10, 12) is in the locked position it is acted upon by a resultant force (53) that prevents both a rotation of the switch blade and its rising up.
