Abstract: A concrete sleeper for a solid carriageway, having a fixing block, which is inserted with the upper section thereof into an underside recess in the concrete sleeper, is mounted elastically by a ring produced from an elastomer and which can be inserted with the lower section thereof into a fillable cut-out in a top layer of the solid carriageway. A base made of an elastic material is arranged on the underside of the concrete sleeper.

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.

Abstract: The invention relates to a screw device for high-adjusting and aligning rails on a track infrastructure comprising a transversal cantilever beam which clamps the rail on the underside and is fixed to a long nut (4) which is variably high guided along a high-adjusting screw (3). The inventive screw device is characterised in that the transversal cantilever beam is embodied in the form of a horizontal screw plate (7) which is pivotally arranged around a horizontal axis (20) on the long nut and on which a truck provided with a clamp fixing device (10,11) for a rail base can perpendicularly move with respect to the high-adjusting screw with the aid of a second screw device (14,16,17).
