Abstract: 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.

Abstract: A method operates a tamping machine on a track. The tamping machine contains a tamping unit, a lifting and lining unit, a measuring system with a measuring value transducer, and a control/regulating device. The lifting and lining unit being actuated by the control/regulating device as a function of a track position recorded by the measuring system in such a way that a treated track section is lifted to a target level during a lifting time. At least two controllers set up in the control/regulating device are selected in such a way that the first controller is activated in a first lifting mode for standard operation and that the second controller is activated in a second lifting mode for turnouts. The respective controller is optimized for the assigned controlled line.
