  • Patent number: 9260821
    Abstract: In a section of a ballasted track that extends over a plurality of crossties, ballast is removed and crossties are removed. Crosstie blocks mounted in concrete slabs are inserted, lifted, and fastened to the rails. The rails are supported by temporary, vertically adjustable supports and adjusted. In an area that extends over a number of concrete slabs, infill concrete is filled in from the underground up to at least part of the height of the concrete slabs, and after the infill concrete has hardened, at least a part of each of the supports located between two respective concrete slabs is removed. The method allows the conversion to be carried out without changing the position of the rails. After the placement of the supports, the track is immediately operable again so that the relevant section need not remain closed until all method steps are completed.

    Abstract: The invention relates to 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.

  • Patent number: 8061432
    Abstract: For the purpose of rehabilitation, a ballast bed of a track is taken up in the form of an upper bed layer by a first clearing device and cleaned. The bulk material accruing in the process is discharged in front of the first clearing device—with regard to the working direction—laterally upon the ballast bed in a bed region. The latter can only be covered by the second clearing device which is configured to be of greater width—with regard to a transverse direction of the track—than the first clearing device. Thus, it is possible to intermediately store bulk material, accruing in a front end region of a machine, on the ballast bed for later use.

    Abstract: The invention relates to the replacement of old ties of a railway track by new ties. This aim can be achieved by spreading the two rails apart from each other. The reception of ballast gravel for producing a recess of ballast is carried out in a region below of the sleeper head of a ballast bed, which is located adjacent to the region of the old sleepers along their longitudinal axis. The received ballast gravel is temporarily stored and, once the new sleepers have been deposited, thrown off for the purpose of ballasting. In parallel and prior to the deposit of new sleepers, excess ballast gravel is ploughed in the recess of ballast so as to produce a leveled surface of ballast.

  • Patent number: 6047531
    Abstract: An apparatus for cutting vegetation under railway tressels and roadways that includes a vehicle chassis having a turntable body mounted thereon. A primary control station is mounted on the turntable body along with a main boom with a vegetation cutting head attached and a second elevating boom with a secondary control station suspended therefrom. Operators man each of the control stations, and the main boom and elevating boom are hydraulically controlled from either of the control stations as the operators cut vegetation from about railway tressels or roadway overpasses while communicating via a two-way intercom system between the control stations. When cutting below the line of sight of the operator in the primary control station, the cutting head is controlled by the secondary control station operator or is lowered by the elevating boom to a level giving a clear view of the vegetation being cut.
