Abstract: A device for fastening a rail to a carrier, wherein the device has a first fastening element, which can be anchored to the carrier, and a second fastening element, which can be anchored to the carrier and has a rest face for a rail foot. The first and second fastening elements each have a contact face, which is formed in a concave manner in the first fastening element and in a mirror-inverted, convex manner in the second fastening element.

Abstract: The invention relates to a switch and to a method for transporting and installing such a switch, which is equipped with longitudinal sleepers, the sleeper sections (2, 3) of which are or can be coupled in a flexurally stiff manner by means of a connecting device (16) embedded in the sleeper heads (4) so that the switch can be folded for space-saving transport. The divided longitudinal sleepers are oriented relative to each other and installed in such a way that the joints of the longitudinal sleepers are aligned along a straight line, which thus can serve as a rotational axis for folding up a side of the switch. The joints aligned on the rotational axis act similarly to a hinge band so that complete switch segments, such as a switch end part or the core region, can be folded along the line.

Abstract: The invention relates to a prestressed concrete sleeper, having at least two sleeper sections that can be coupled or are coupled rigidly by a connection device embedded in the sleeper heads, wherein the sleeper sections each comprise a concrete in the region adjacent to the connection device which has a higher rigidity than the concrete in the other regions

Abstract: Concrete carriageway for rail vehicles, having single- or multiple-block sleepers embedded in a carriageway panel, whereby the carriageway panel has areas of thinned cross-section disposed transverse to the direction of travel for generating cracks and in each has at least one body for transmitting transverse forces which overlaps the region of thinned cross-section on both sides.

Abstract: Disclosed is a method for continuously producing switch ties which differ from one another with respect to the length thereof and the mounting position of rail fastenings. Said method comprises the following steps: one or more supporting metal sheets and/or one or more internal molds are mounted in a tie mold according to the length and the shape of the switch tie to be produced, or at lease one tie mold is used which is adapted to the geometry of the switch tie to be produced; bracing bars are inserted as a reinforcement; the bracing bars are simultaneously tightened in an automatic manner by means of pairs of spindles, each bracing bar being individually tightened; concrete is filled into the tie mold; the switch tie is allowed to set; the switch tie is removed from the mold.

Abstract: Fixed carriageway for rail vehicles having sleepers embedded in a carriageway panel and a reinforcement includes plural longitudinal and transverse rods disposed parallel and transverse to the sleepers, wherein the longitudinal rods and transverse rods are electrically isolated from one another.

Abstract: Concrete sleeper with fixing elements incorporated, insertable or inserted into a sleeper body for fixing rails, wherein the sleeper body of the concrete sleeper (1, 18) has at least four apertures for fixing elements per rail (5) to be fixed, the apertures being arranged in pairs to the left and right of the rail support area (2), the two apertures for fixing elements of one pair being arranged staggered in the longitudinal direction of the concrete sleeper (1, 18).

Abstract: Fixed carriageway for rail vehicles, which is mounted on resilient elements, the concrete support panel including prefabricated panels and a layer of in-situ concrete applied thereon, wherein the prefabricated panels rest on the resilient elements and form a monolithic bond with the in-situ concrete.

Abstract: Superstructure for a railway, wherein at least one component of the superstructure (8) has a data carrier (7) for digitally stored data readable with a reading device (11).

Abstract: Method of adjusting the height of a fixed rail carriageway, in which the sleepers supporting the rails are embedded in a carriageway panel resting on a substrate includes the steps of separating the carriageway panel from the substrate at the common contact face, forming filling apertures extending from the upper face to the lower face of the carriageway panel, lifting the carriageway panel to a fixed target height, incorporating a flowable casting material through the filling apertures in order to fill the space between the carriageway panel and the substrate, wherein separation is effected by pressure impacts.

Abstract: Method of manufacturing a concrete sleeper, comprising the following steps: insertion of pre-stressing rods into a sleeper mould, simultaneous automated tensioning of the individual pre-stressing rods, filling of the sleeper mould with concrete, leaving of the concrete to harden, removal of the concrete sleeper from the mould, wherein for one concrete sleeper more than four, in particular five to eight, pre-stressing rods are used and the pre-stressing rods are tensioned individually yet simultaneously.

Abstract: Spindle device for the height adjustment and alignment of tracks on a substructure, having a transverse cantilever which is fixed to an elongate nut adjustable in height on a height adjustment spindle and which engages under the rail and which is formed as a horizontal spindle plate which is mounted on the elongate nut pivotably about a horizontal axis and on which a slide provided with a clamping mount device for the rail foot is displaceable by means of a second spindle device transverse to the height adjustment spindle.
