Abstract: The invention relates to a sleeper transport vehicle (1) having a loading area (25) which includes a lower supporting loading plane (7) and an upper supporting loading plane (8), wherein in each loading plane (7,8) a guide (10) is arranged in which pallets (9) are guided in the longitudinal direction of the sleeper transport vehicle (1), wherein, at a front side, a transfer area (26) is arranged into which the guides (10) protrude in order to pass along during a working operation pallets (9) with new sleepers (15) in one loading plane (7, 8) to a further sleeper transport vehicle (1) or loading/unloading vehicle (34) arranged at the front side, and to receive pallets with old sleepers (16) in the other loading plane (7, 8).

Abstract: A track maintenance wagon (1) for picking up and/or laying a track panel (10), comprising a wagon frame (2) supported on on-track undercarriages (4), wherein two longitudinal beams (7) of the wagon frame (2) delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel (19), and wherein crane rails (8) are arranged on the longitudinal beams (7) for a gantry crane (11) mobile in the longitudinal direction (3) of the wagon. In this, buffers (13) are arranged at two free ends (12) of the longitudinal beams (7).

Abstract: A sleeper transport vehicle has a loading area which includes a lower supporting loading plane and an upper supporting loading plane, wherein in each loading plane a guide is arranged in which pallets are guided in the longitudinal direction of the sleeper transport vehicle, wherein, at a front side, a transfer area is arranged into which the guides protrude in order to pass along during a working operation pallets with new sleepers in one loading plane to a further sleeper transport vehicle or loading/unloading vehicle arranged at the front side, and to receive pallets with old sleepers in the other loading plane. In this, it is provided that in each loading plane a pushing device for pushing the pallets along the guide is designed as at least one circulating chain protruding into the transfer area, and that coupling elements are arranged on the pallets for temporary coupling to the chain.

Abstract: A track maintenance machine, constructed to be mobile on a track, for consolidation of a ballast bed underneath a track, includes a machine frame supported on an undercarriage and a consolidating device, connected to the machine frame, which includes at least one consolidating element constructed to be lowered. The consolidating element is constructed as a consolidating plate which, in a working position, is larger in a longitudinal direction of the track than a distance between two sleepers of the track, and the consolidating plate is disposed to be rotatable in order to turn the consolidating plate into a passing position for lowering or raising between two sleepers. A method for consolidation of the ballast bed underneath a track by using a track maintenance machine is also provided.

Abstract: During the tamping of a switch, a switch section delimited by two adjacent sleepers is photographed in a front machine section for producing a reference photo, and the photo is stored. The stored reference photo is automatically made available on a monitor, positioned in a work cabin, for observation by an operator as soon as the tamping tools are situated above the section of the switch shown by the reference photo.

Abstract: A ballast sweeping installation for picking up and distributing ballast located on a track includes a sweeping brush rotatable about an axis of rotation, a ballast conveyor belt disposed ahead of the sweeping brush relative to a brush rotation direction, and a ballast guiding plate positioned between the sweeping brush and the ballast conveyor belt for passing the ballast on to the ballast conveyor belt. A length of the ballast conveyor belt delimited by two deflection ends is shorter than a length of the sweeping brush along the axis of rotation. Additionally, the ballast conveyor belt is configured to be displaceable in a transport direction relative to the sweeping brush by a drive. Thus, an optimal ballast distribution in tamping zones of the track is made possible.

Abstract: A track maintenance wagon (1) for picking up and/or laying a track panel (10), comprising a wagon frame (2) supported on on-track undercarriages (4), wherein two longitudinal beams (7) of the wagon frame (2) delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel (19), and wherein crane rails (8) are arranged on the longitudinal beams (7) for a gantry crane (11) mobile in the longitudinal direction (3) of the wagon. In this, buffers (13) are arranged at two free ends (12) of the longitudinal beams (7).

Abstract: A machine (1) for stabilization of a track (2) has a machine frame (5), mobile on the track by means of on-track undercarriages, on which a stabilizing unit (4) is arranged which has vertical adjustment drives (6) as well as a vibration exciter (7). The stabilizing unit is designed to be displaceable relative to the machine frame (5) in a longitudinal direction (23) of the machine by means of a longitudinal displacement drive (24).

Abstract: For correction of a track position in connection with ballast cleaning, after cleaned ballast has been returned to a track, the actual position of the latter is measured while determining actual position data. Parallel to that, fixed point correction values are determined by a sighting trolley following behind. The actual position data and the fixed point correction values are transmitted to the tamping machine, following behind, and are used for determining correction values for a desired track position to be created by tamping.
