Abstract

In a device for facilitating the re-positioning of moveable rails or rail components, in particular of tongue rails (7), in which the rails (7, 7'), during the re-positioning operation are supported on rollers (10, 10') forced against the underside of the rail base by spring action, the rollers (10, 10') in at least one end position (7, 7') of the re-positioning operation are pressed by the force of the spring against one edge (14, 15) of the rail base. In this way it is possible to combine the advantages of reduction of the sliding friction during the re-positioning operation with a flexible securing of the end position of the currently involved adjusted position of the moveable rail or rail component (7, 7').
