A track maintenance machine for stabilizing a ballast bed of a track after a tamping operation, includes a machine frame mobile on on-track undercarriages and a stabilizing unit which has rollers for gripping a track grid and a vibration generator for actuating the track grid with a vibration. A clearing device is disposed at both longitudinal sides of the track maintenance machine in front of the stabilizing unit with regard to a working direction. Each respective clearing device includes a clearing tool which can be lowered into the ballast bed to remove ballast from a respective sleeper-end region. Thus, preconditions are created by using the stabilizing unit to achieve an increased lowering of the track grid as compared to a normal stabilizing procedure. A method for operating a track maintenance machine is also provided.

The invention relates to a tamping tine for a tamping machine for tamping a track, including a tine shaft which has at its upper end a retaining portion for fastening in a tine mount and which merges at its lower end into a tine plate. In this, a sensitive element of a sensor is arranged in a recess of the tine shaft, and the tamping tine includes a coupling element for transmission of a sensor signal. In this manner, the tamping tine fulfils a sensor function for recording measuring values occurring in the tamping tine.

A system for surveying a track includes two outer measuring devices and a central measuring device disposed therebetween, relative to the longitudinal direction of the track. Each measuring device has a specific position relative to the track in order to detect geometric track parameters. One outer measuring device includes a camera with a recording area in which a measuring object of the other outer measuring device and a measuring object of the central measuring device are disposed. The camera is connected to an evaluation device for pattern recognition. All of the position parameters of the track required for precise lining and levelling of the track are thus recorded by a single camera. A method of operating the system is also provided.

A method for maintenance of a permanent way, roadway or travel path for rail vehicles includes determining the actual condition of the permanent way by using a measuring system to record measurement data. Objects along the permanent way are detected from the measurement data by using an evaluation device. A detected object is assigned to an object class, and at least one object class identification linked with positional data is stored in a database for a detected object. The actual condition of the permanent way is thus stored in an object-based manner, and a comparison with a target condition or with historic actual conditions is used for the planning and execution of maintenance measures. A maintenance system for executing the method is also provided.

A method of determining the actual position of a track relative to a fixed point located in a lateral vicinity of the track by using a registering device being mobile on the track includes surveying the position of the fixed point relative to the track. The registering device is moved along the track, image pairs of the lateral vicinity of the track are continuously recorded by a stereo camera system on the registering device and the fixed point is searched for in the image pairs by pattern recognition carried out in an evaluation device. Upon recognition of the fixed point, the position of the fixed point relative to the track is determined by evaluating at least one image pair. This creates the possibility of surveying fixed points in passing with the configuration of the fixed point not being bound to any special form. A measuring system is also provided.
