Abstract: The invention pertains to an end position detector for movable switch parts (3) which comprises a rod assembly and a housing (12), into which the rod assembly penetrates and in which at least one sensor for sensing an end position of the rod assembly is arranged. According to the invention, the rod assembly is connected to the movable switch part (3) such that it can be pivoted in a vertical plane that lies transverse to the longitudinal direction of the rails, wherein the rod assembly comprises at least one rod (8) of circular cross section, and wherein said rod (8) in its region that penetrates into the housing (12) in a sealed fashion carries on its periphery at least one switching flank (13) that cooperates with a switch contact (16).

Abstract: In a switch actuator for movable frogs (1), comprising at least one cylinder piston unit (5) having a defined preset piston stroke, the cylinder piston unit (5) is connected with bearings (6) capable of being displaced in the axial direction of the piston stroke, which bearings are connected with a stationary substructure for the adjustment of a defined center position of the piston stroke and the driver for the movable frog (1). The driver for the movable frog (1) is coupled with the cylinder piston unit (5) with stops (9) displaceable in the axial direction being interposed.

Abstract: The invention relates to a device for displacing and locking movable switch parts (1), comprising a hydraulic piston, which is formed by a rod (6) and cooperates, via coupling or locking members (8), with an axially displaceable sleeve (5) intended to receive the radially displaceable coupling or locking members (8), The displaceable sleeve (5) is coupled with the movable switch parts (1) and an externally arranged tube (4), at least partly overlapping the sleeve (5) and the rod (6). A hydraulic duct (11) is connected to the externally arranged tube (4), on a front face of the sleeve (5), facing away from the coupling site for the movable switch parts (1).

Abstract: Transition Rail and Method for Producing Said Transition Rail In a transition rail (1) for the connection of rails having different rail cross sections (2, 3), the transition rail (1) comprises two transition zones (a,c), wherein in a first transition zone (c) the larger-height cross-sectional profile is reshaped to transition into a smaller profile height and in the following, second transition zone (a) the rail foot is worked to match the new profile of the consecutive rail foot. The method for producing the transition rail is characterized in that the transition rail is at first heated and introduced into a press mold, whereupon the rail is reshaped in the web region and pressed in the direction of the profile height, and that the rail foot is mechanically worked following complete reshaping.

Abstract: 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.

Abstract: The invention relates to a device for locking the end positions of movable switch parts and, in particular, the movable point (1) of a frog, in which two relatively axially displaceable parts are capable of being displaced into a position coupled with each other in a positive manner in at least one direction of movement, wherein the relatively displaceable parts are comprised of a tube (5) and a rod (6) guided within the tube (5) and are at least partially arranged in a stationary outer tube (4), whereby locking members (8) cooperate with the relatively axially displaceable parts (5, 6) as well as the outer tube (4) and are capable of being displaced in the radial direction into a locking position in a recess or inner annular groove (15, 16) of the outer tube (4). Said device is designed such that the outer tube (4) is comprised of two tube parts (17, 18) capable of being axially displaced within each other, and that each tube part carries at least one recess or inner annular groove (15, 16).
