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.

L'invention concerne un dispositif d'aiguillage de voie ferrée, comprenant une contre-aiguille (12), une lame d'aiguille (14) se prolongeant en un rail standard, tel qu'un rail à gorge, un contre-rail (10), un élément de retenue (18) maintenant la lame d'aiguille par liaison de force côté rail standard, en particulier par l'intermédiaire d'un élément de cale, et un dispositif de glissement (16, 30, 32, 34) supportant la lame d'aiguille par glissement. L'objectif de l'invention est d'utiliser un minimum de composants pour concevoir ce dispositif, sans que la fonctionnalité en soit affectée. A cet effet, le contre-rail (10) est une section usinée d'un profilé laminé (24) en acier pour rails qui présente côté rail standard une section (26) correspondant au rail standard et se prolonge dans celui-ci de manière affleurante.
