  • Patent number: 8978995
    Abstract: A trackbed liner which has a particular utility in a railway trackbed, as well as in other trackbeds such as tram trackbeds. The trackbed liner may include an upper support layer; a lower support layer; and at least one middle filtration layer of a material having a plurality of pores and which is normally impermeable to liquid water. In use and under the load of a vehicle acting on the trackbed, the filtration layer permits passage of liquid water upwardly therethrough but restricts the passage of solids materials, so as to restrict pumping erosion of material located beneath the liner. The trackbed liner may be used to renovate a trackbed comprising ballast contaminated with clay particles. The method includes removing contaminated ballast; laying the trackbed liner; and locating fresh ballast on an upper surface of the liner to provide a renovated trackbed.

    Abstract: The invention relates to a method for introducing a flowable and foamable reaction mixture from the top into a ballast body having sleepers embedded therein, in which method said mixture is introduced into the ballast body laterally of the sleepers, notably preferably depending on the height of the ballast body at the point of application, and in a quantity that is all the larger the more upwards in the ballast body the application point is situated, wherein the mixture is adjusted in such a way that the foam formation process will begin only when the front of the mixture flowing downwards inside the ballast body has reached the bottom side or the region in the vicinity thereof of the ballast body so that the foam formation is carried out within the ballast body from the bottom towards the top.

  • Patent number: 7500617
    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.

  • Patent number: 7484669
    Abstract: A rail cover and support for mounting and insulating the rails of an electric transit system in which the rail cover is vulcanized both to the rail and outer skid support at the manufacturing site prior to delivery to the field and a rail cover completely surrounds both the base flange and web portion of each rail and terminates along the undersides of the top flange. In one form, the upper free ends of the rail cover are increased in thickness to form bumpers along opposite sides of the rail to cushion it against undue shifting or vibration. In fabricating the rail, a sheet dielectric material is vulcanized to the rail with or without a skid plate.

  • Publication number: 20080257971
    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.

  • Publication number: 20080173724
    Abstract: A track superstructure for a railway on a subgrade (12) inclined transversely to the length thereof, comprises a ballast structure (16) of individual ballast stones (18), and sleepers (20) embedded in the ballast structure, on which rails (24) may be mounted, the ballast structure (16) comprising load dissipation regions (26) beneath the sleepers (20), said regions receiving loads acting vertically on the ballast structure (16) via said sleepers (20) when a train rides on the rails (24) and transferring these loads to the subgrade (12) below the ballast structure (16). This transfer is characterized in that substantially only the voids between the ballast stones (18) within the load dissipation regions (26) of the ballast structure (16) are filled with a foam material (28), especially a PU foam material, for fixing the ballast stones (18) in a stable position, and an elastic drain layer (14) is arranged between the ballast structure (16) and the subgrade (12).

  • Patent number: 7093768
    Abstract: A rigid track consisting of concrete, in particular pre-cast components, comprising a slab with traversing fixing elements, or a plurality of fixing elements arranged thereon, of rails for track-borne vehicles. The inventive rigid track is characterized by a pre-cast concrete component constituting a protuberance that is positioned on the slab, parallel to at least one rail and located on at least one side of the rail. The protuberance acts as a guard and a guide for the vehicle during derailment.
