  • Patent number: 6527231
    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.

  • Patent number: 6409092
    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.

  • Patent number: 6270018
    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.
