A device (3) for positioning track processing tools (2) on a track includes: at least two support modules (29, 30), each having at least one tool support (31a, 31b) for supporting the at least one track processing tool (2), and a horizontal positioning apparatus (32) to which the at least one tool support (31a, 31b) is attached, for moving the at least one tool support (31a, 31b) in a horizontal direction (33a). A rotating apparatus (24) for rotating the at least two support modules (29, 30) has at least two rotating units (25, 26) for rotating the at least two support modules (29, 30) independently of one another. A first transverse positioning apparatus (16) is provided for linearly moving the at least two support modules (29, 30) in a horizontal direction (33a, 33b, 33c) and at an angle of at least 45? to the longitudinal direction (9) of the track (4).

A vehicle for machining a rail by grinding and/or planing, including a metal abrasive module, an eccentric drive performing an eccentric movement, at least two abrasive blocks connected with the eccentric drive, and a force exerting drive pressing at least one abrasive block onto the rail, wherein the metal abrasive module and/or at least one of the abrasive blocks is individually tiltable around an axis parallel to the rail, and wherein at least one of the abrasive blocks is individually pressable onto the rail. This allows a more effective and improved metal removal and rail shaping capabilities.

A method for carrying out work on a railway track by means of a rail vehicle, comprising a track motor vehicle with at least one electrically operable treatment device and an energy supply device for providing electrical energy, as well as a trailer wagon coupled to the track motor vehicle with an energy storage device for providing electrical energy, with the rail vehicle being driven to a track point to be treated, with the trailer wagon being decoupled from the track motor vehicle, and with the track point to be treated being treated by means of the track motor vehicle. Before and/or after treatment by means of the track motor vehicle, the track point is treated by means of the trailer wagon by supplying an electric traction drive of the trailer wagon and a treatment device of the trailer wagon with electrical energy from the energy storage device. In this way, the trailer wagon is used autonomously for track treatment.

The present disclosure relates to a railroad track tool apparatus. The apparatus comprises a tool configured to perform an operation to the rail of the railroad track, a clamp assembly, and a coupling. The clamp assembly is moveable between a clamped position and an unclamped position to removably couple the tool with the rail. The clamp assembly is moveable along the rail. The coupling is configured to couple the tool to the clamp assembly. The coupling comprises a pivot, a linkage assembly comprising an arm coupled to the pivot, and a head coupled to the linkage assembly. The coupling is configured such that the tool is moveable between an inner side and an outer side of the rail, rotatable toward and away from the inner side or the outer side of the rail, and rotatable toward and away from an underside of the rail.
