Abstract: A grooved rail core piece including a core piece intersection area formed by intersecting grooves as an overflow area. The core piece has two construction profiles with interconnected outer fishing surfaces (22,24) extending in a longitudinal direction. In order to enable the intersection area of the core piece to be renewed in a simple manner, the intersection-point area of the core piece includes an interchangeable insert (36) which is arranged in a recess in an at least positive fit, the recess being defined by the sections of the construction profiles and by the sections of the lining parts (30,32) disposed in the outer fishing surfaces (22, 24), and the insert is fixed by means of at least two wedge elements (38, 40) which can be clamped in the lining parts. The lining parts and the construction profiles are connected by means of at least one clamping element protruding there through in a non-positive fit.

Abstract: The invention relates to a superstructure switching device comprising a stock rail (12), a switching rail (14) that changes into a control rail such as a channel rail, a guide rail (10), a retainer (18) that holds the switching rail on the control rail side in a force-fit, in particular by means of a wedge element and a slide device (16, 30, 32, 34) that supports the switching rail in a sliding manner. The aim of the invention is to use a minimum of components for configuring the device, without forfeiting any functional efficiency. To achieve this, the guide rail (10) is a machined section of a rolled rail-steel section (24), which has on the control-rail side a cross-section (26) that corresponds to the control rail and seamlessly changes into the latter.
