Abstract: A biblock or multiblock transverse member is provided with concrete blocks which includes plates connected to each other with the aid of an incorporated reinforcement elements. The transverse member consists of many individual prefabricated blocks whose two reinforcement elements are interconnected, more particularly welded.

Abstract: Device for monitoring the state of the substructure of fixed tracks, especially in the transition region of substructure supporting plates, measuring bolts, which, in vertical recesses, pass freely through the track plate above, being fastened at the ends of the substructure plates, which are to be monitored.

Abstract: A device for monitoring the superstructure state especially of fixed railroad tracks, with a height sensor system, which is installed in a measuring vehicle, preferably constructed as a laser scanning system, for determining the height position of an anchor clamp and/or of the base of a rail and/or of a railroad tie.

Abstract: A ceramic material, includes SiO2 and Na2O and/or K2O. The material is characterized by a porosity of over 60% and by pores, more than 70% of which have a pore size ranging between 0.1 and 15 &mgr;m. The ceramic material can be used as filtering material, for water storage and as adsorbent material.

Abstract: A railroad tie having a compact design for a fixed track with an overlay of asphalt of the Getrac A3 construction with a dowel stone which is inserted in a recess and which protrudes downward into engagement with a cavity pocket of the asphalt track. The railroad tie is constructed as a double railroad tie which forms only a narrow gap with the adjacent railroad tie in order to make radial laying (curve) possible and which is provided in the region of the dowel stone on the underside with lateral constrictions so that the cavity pockets can be filled subsequently.

Abstract: A two-block concrete railroad tie for a fixed rail carriageway with an at least partially continuous reinforcement, which is exposed between the blocks and, after alignment, engages the sealing compound over a supporting layer, becoming anchored in it, the blocks being provided with a mounting surface, which is shortened in the longitudinal direction and from which slanting side surfaces extend upward at least at the front side.
