Abstract: A machine for profiling and distributing ballast of a track, having a frame supported on on-track undercarriages and lateral ballast pick-up devices which are adjustably fastened to the frame, wherein each ballast pick-up device is actuated by a conveyor drive. In this, the machine is designed in such a way that, in an inoperative position, the upper contours of the machine are arranged below a delimiting plane which slopes downward in the working direction and extends through a field of vision of a driver's cabin of a rail vehicle to be coupled to the machine at the rear end thereof. Thus, the machine can be employed as a leading wagon of the rail vehicle, wherein sufficient visibility from the driver's cabin to the track is ensured.

Abstract: The invention relates to a track maintenance machine with a conveyor or excavating chain arrangement for removing and collecting railway ballast and/or other formation or substructure layers of a track structure, comprising a cutter bar which can be positioned below a track and which has at least two bar elements, each adjustable in position and alignment, and which is attached on the one hand to an ascent channel and on the other hand to a return channel, furthermore comprising a guided excavating chain consisting of a plurality of chain links, wherein the arrangement can be fastened to a machine frame by means of at least one height-adjustable suspension device. It is provided that the excavating chain is designed to be divisible, that the bar elements can be connected via a coupling to form a closed overall unit, and that the arrangement can be variably adjusted in its excavating working width by adjusting the position of the bar elements.

Abstract: The invention relates to a rail vehicle (1) having a machine frame (2) supported on on-track undercarriages (4), on both sides of which are arranged—in the longitudinal direction (3) of the rail vehicle—crane rails (8) for a mobile gantry crane (11). In this, for lifting or lowering of the gantry crane (11), a crane rail section (12) of the respective crane rail (8) is arranged to be vertically adjustable by a drive (18). In this manner, contrary to the prior art, a higher gantry crane (11) can be used without violating a given clearance profile during transfer travel.

Abstract: A machine having a ballast take-up device for taking up ballast located underneath a track. The take up device has an endless clearing chain guided in a chain channel. In a connecting joint from a transverse channel to a transport channel. There is also a ballast deflector blade pivotable about a pivot axis. Arranged on the ballast deflector blade is a ballast conveyor, designed for ballast transport in the direction towards a pivot axis by means of a conveyor drive. With this, it is possible to expand the operating range of the ballast take-up device, as needed.

Abstract: In a method for renewing a track (2) and cleaning a ballast bed (3), the old track (2) is lifted off the ballast bed in sections as a track panel (15), transported forward in a working direction (4) and deposited on track panel wagons (8). The exposed ballast bed (3), forming a renewal gap (17), is cleaned by a cleaning machine (11), spoil (32) accruing in the process is transported forward underneath the track panels (15) deposited on the track panel wagons (8), and stored in hopper cars (10). New rails (29), pre-deposited underneath new sleepers (27) positioned on sleeper wagons (14), are pulled forward into the renewal gap (17) by the cleaning machine (11) and deposited on the cleaned ballast bed (3). The new sleepers (27) are laid down on the cleaned ballast bed and connected to the new rails (29) lifted off the ballast bed (3).

Abstract: A storage wagon (1) for bulk material (2) has, above the transfer end (9) of a bottom conveyor belt (4) and underneath a discharge end (15) of an auxiliary conveyor belt (14), a deflector plate (17) extending perpendicularly to the longitudinal direction (3) of the wagon. The deflector plate (17) is designed to be pivotable about a pivot axis (18) relative to the loading container (5) for changing a deflection angle ? enclosed with a conveying plane (19) of the bottom conveyor belt (4).

Abstract: A vehicle combination for cleaning ballast on a track consists of a first ballast-collecting vehicle at the front with respect to a working direction, equipped with two edge-clearing chains which are mutually opposed across the width of the track and are designed to collect the ballast lying in a track bed region adjacent to the sleeper ends, and also consists of a subsequent second ballast-collecting vehicle having a continuous clearing chain that can be placed around the track to collect the ballast lying under the track, and comprising sieve systems for cleaning the ballast. In front of the first ballast-collecting vehicle there are two mutually separable sieve vehicles disposed one behind the other in a longitudinal direction of the machine and each having a sieve system. The two sieve vehicles can be loaded via a first conveyor belt line with ballast collected by the ballast-collecting vehicles.

Abstract: A bulk material loading wagon (1) for incorporation into a loading train consisting of several such wagons has a storage box (3) for storing bulk material, the storage box being open at the top and fastened to a wagon frame (2), and—associated with the storage box—a bottom conveyor belt (5) extending in the lower region of the storage box (3) and in the longitudinal direction of the wagon. The wagon frame (2) is equipped with an opening (16), arranged between two adjacent on-track undercarriages (14), for passage of a lower section—adjoining the lower deflection end (9)—of a transfer conveyor belt (8). A drive (18) is provided for displacement of the transfer conveyor belt (8) in its conveying- or longitudinal direction (4) through the opening (18) relative to the wagon frame (2).

Abstract: In a method for stabilizing an earth formation exposed after removal of a track and ballast, in a first working pass in a work section following a rear crawler track with regard to a working direction, parallel to the removal of the ballast the earth formation is loosened up, aggregates are introduced, and grading takes place. In a second working pass, the earth formation to which aggregates have been added is mixed thoroughly by getting picked up by means of a clearing chain and transported onward to a discharge point located behind the rear crawler track and discharged again upon the exposed earth formation, after which, by grading and consolidating the discharged earth formation, a rehabilitation layer is formed.
