A longitudinal beam of a track maintenance vehicle is connected at a beam exterior sidefacing away from the opposite longitudinal beamto a rail transport device provided for receiving rails. The rail transport device is displaceable by means of a displacement drive in the transverse direction of the machine relative to a machine frame within a displacement path s delimited by a transportand a loading position.

A maintenance vehicle has side walls for creating a work space, delimited by the same, for working personnel situated on a track. The side walls are arranged on a vehicle frame and configured to be distanced from one another in a transverse direction of the vehicle. For treatment of a track section situated within the work space, an industrial robot is arranged on the vehicle, having at least three motion axes, media couplings for energy supply as well as a tool coupling for selective connection to a track treatment tool.

A maintenance vehicle has a vehicle frame, supported on on-track undercarriages, on which are arranged two side walls extending in a longitudinal direction of the vehicle and adjustable with respect to one another and relative to the vehicle frame in a transverse direction of the vehicle by way of drives. The vehicle is equipped with at least one load crane which is displaceable on a crane guide that extends in the transverse direction of the vehicle. The crane guide, designed to be elongatable in the transverse direction of the vehicle, is connected at each end to a side wall.

A rail tool-holder cart (1) comprises a T-shaped support frame (2), a tool-holder arm, (12) rotatable about a vertical axis and tiltable between an upper position and a lower position and having a coupling interface for a tool (17, 17), a spring (19), which pushes the tool-holder arm permanently towards the upper position, so as to compensate at least one part of the weight of the tool (17, 17), as well as adjustment means (20) for adjusting the spring thrust (19).

A work train lays a rail of a railway track. The work train has a heating device with a heating zone, gas burners, and a radiant body interposed between the gas burners and the heating zone. The radiant body has openings that open into the heating zone. The work train is moved in a laying direction, so that at each moment a portion of the rail to be fixed passes through the heating zone. Heat is supplied to the rail to be fixed through the heating zone by feeding the gas burner so that no flame emerges from the openings in the heating zone and that at least 75% of the heat supplied to the rail is transmitted by radiation from the radiant body. Then the rail is fixed after the heat has been applied to a tie of the railway track behind the heating zone in the laying direction.

The invention relates to the field of railway construction, in particular to an equidistant laying railroad track anvil device, comprising a fuselage and a storage cavity provided in the top wall of the fuselage with an upward opening, and a bottom wall of the storage cavity is provided with an upwardly-oriented storage cavity. A conveying cavity is provided with a conveying device for the rootstock conveyance, and the conveying device uses the rotatable chain in the conveying cavity to convey the anvil to the left. The present invention provides an equidistant railroad track anvil device. The structure is simple and easy to operate. It can realize the equidistant automatic placement of railway rootstocks. The device can independently transport the rootstocks, and can perform intermittent movements, and the placement of the rootstocks in the movement gap. It has strong functionality, good stability, and is convenient for production promotion use.
