Fastening for a rail and arrangement for fastening of rails The invention relates to a fastening for a rail for securing a rail () whose foot is resting on a concrete sleeper (), comprising at least one elastic clip () having several legs of which at least one leg extends inside a shoulder () or channel of a holder () 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 () is arranged detachably in the concrete sleeper () or in a plate element resting thereon and is connected to the concrete sleeper by a bolt element.

Arrangement for fastening railroad rails to a sleeper

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. A second locating means holds the rail fastening clip in a second position different from the first position such that the toe portion of the clip sits on a ramp of the loading means in a preload condition in which the clip does not bear on the rail

Fastening rail in railway slide chair assembly

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.

Rail fixing device

A bearing for a section of a track includes, along the track sections, profile sections which deviate from each other, especially in the form of points. A plurality of supporting points is provided with a ribbed plate, in addition to an intermediate layer made of an elasticized material disposed between the ribbed plate and an associated railway sleeper. In order to obtain identical subsidences along the sections of track, substantially each support point has an identical maximum subsidence with respect to each excavated track section.

Bearing for a section of a track

The invention relates to a system for securing and/or controlling the final position of a tongue rail ( ) that can be adjusted in relation to a rigid rail ( ). A catch element extends from said tongue rail and interacts with a lever element in such a manner that in the respective final position of the tongue rail the latter is supported and the position of the tongue rail is measured.

System for securing and/or controlling the final position of a rail

The invention relates to a superstructure points device, in particular intended for a grooved rail, comprising a box-like substructure ( ) with stock rail ( ), if necessary an additional/supporting rail ( ) and slide plate ( ) on which a tongue rail ( ) 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 ( ) is mounted elastically in a stationarily arranged frame ( ) of the points device.

Superstructure points device

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.

Superstructure construction

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).

Bearing for a part of a railroad track

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.
