Abstract: A concrete slab structure for supporting railway track is itself resiliently supported on a base structure by a spring system comprising tubes secured against longitudinal movement in holes extending through the slab from its top surface to its bottom surface, springs each arranged in a respective one of the tubes and an adjustable spring abutment at the upper end of each of the tubes for pre-loading the springs against the base structure.

Abstract: A method of and arrangement for correcting the height of a railway upper structure with a reinforced concrete plate thereon into which plate a reinforced concrete part as support for rail holding members is so inserted that the reinforced concrete part is positioned above a just finished or poured concrete section of the reinforced concrete plate in conformity with its end position and is subsequently lowered and jarred into the not yet hardened concrete of the reinforced concrete plate.

Abstract: A technique for rapid installation of corrosion resistant quench car railroad track wherein levelling blocks are embedded in a slag base, a layer of polyethylene is laid over the base and levelling blocks, and a thin layer of gravel is disposed on the polyethylene sheet. Mating precast concrete panels are placed end to end for supporting the ties and rails, with the adjacent edges of the panels overlying the levelling blocks. Ties and rails are installed on the upper surfaces of the panels, and drainage ramp and channel structures are provided on opposite sides of the panels. The panels have vertical holes therein through which an epoxy resin is injected into the underlying gravel layer, the epoxy being horizontally directed by the plastic sheet. The epoxy subsequently hardens, bonding the gravel particles together and forming a stable underlayment for the concrete panels.

Abstract: A replaceable track apparatus comprises two channels separated one from the other and formed in a concrete bed. The channels are lined with a corrosion resistant material and have located therein, a track containing vessel which comprises a corrosion resistant shell having a railroad track positioned therein at a predetermined location and supported by means of a reinforcing rod configuration secured to the track and held within the vessel by a concrete binder. The track vessel assemblies are located as indicated, in each channel. The apparatus assures the proper alignment of the track members to enable operation of a railway system on the tracks, while providing rapid removal and replacement of the track assemblies when desired, as the assemblies wear due to corrosion.

Abstract: A rail track that reduces noise and vibration for particular use in rapid transit and subway lines. The track is formed of a conventional rail embedded in a pre-stressed concrete bed. Sections of such jacketed rails are joined together by means of flanges, one of which is welded to one side of each rail end, with the bolt holes in the flanges and the joined rails oriented at an angle to axes of the rails so as to transfer a tension load between each rail of a joint. The pre-stress tension wires of the concrete bed extend beyond the ends of each section and are individually joined by turnbuckles or other tension creating couplers. The bottom of each concrete bed section is mounted on a solid sheet of rubber or other elastomer.

Abstract: The disclosure concerns a modular liquid collection system for use on the roadbed of a railroad, particularly at fueling stations. The modules are arranged end-to-end along the track, and are composed of precast components made of reinforced concrete or foamed plastic. In the most complete form, each module includes a central basin which rests on the ties between the rails, and a pair of side basins which rest on the ties at the outboard sides of the rails and which are formed with integral curbs. The basins have liquid-receiving surfaces which are pitched in both the transverse and longitudinal directions and have centrally located drain openings which overlie a transverse drain trough. The basins of the end modules of a series are equipped with removable end curbs.
