An aspect includes a vehicle that includes rail inspection sensors configured for capturing transducer data describing the rail, and a processor configured for receiving and processing the transducer data in near-real time to determine whether the captured transducer data identifies a suspected rail flaw. The processing includes inputting the captured transducer data to a machine learning system that has been trained to identify patterns in transducer data that indicate rail flaws. The processing also includes receiving an output from the machine learning system, the output indicating whether the captured transducer data identifies a suspected rail flaw. An alert is transmitted to an operator of the vehicle based at least in part on the output indicating that the captured transducer data identifies a suspected rail flaw. The alert includes a location of the suspected rail flaw and instructs the operator to stop the vehicle and to perform a repair action.

The invention relates to a method for determining an actual position of rails of a track by means of an optical sensor device, positioned on a rail vehicle, for recording the position of the track and adjacent installations. In this, it is provided that, by means of the sensor device, a course of the track and a course of the adjacent installations, in particular a catenary installation, are recorded for a track section as preliminary actual data, and that the preliminary actual data are transformed into corrected actual data in an evaluation device in that a recorded course of at least one adjacent installation is transformed into a course with a specified geometric shape. In addition, the invention relates to a system for implementing the method.

The invention relates to a machine for compacting a ballast bed of a track with a machine frame supported on rail-based running gears and a height-adjustable stabilising unit connected thereto, comprising a vibration drive and an axle with wheel flange rollers movable on rails of the track, whose distance to each other extending perpendicularly to the longitudinal direction of the machine can be varied by means of a spreading drive, as well as a roller clamp that can be pressed against the rails by means of clamping drives. The spreading drive and/or the clamping drives are set up to apply a predefined variable horizontal load force to the rails, whereby a measuring device is arranged to detect a rail head deflection and/or track gauge change caused by the variable load force. In this way, it can be determined by means of the stabilising unit whether the track panel is intrinsically stable.

A method for measuring and displaying the track geometry of a track system uses a track-driveable permanent-way machine, comprising a control measurement system measuring the track position to be corrected before a lifting and lining device, an acceptance measurement system measuring the corrected track position after it, and output units displaying the measured values. The lifting and lining device is controlled depending on the measured values of the control measurement system and the acceptance measurement system to achieve a specified target track geometry. A three-dimensional position image is calculated from the curvature image (k.sub.(s)), longitudinal level image (h.sub.(s)) and superelevation image (u.sub.(s)) of the target track geometry, put into a perspective display, and displayed by the output unit, supplemented by measured error curves for track parameters of track direction, superelevation, twist, and longitudinal level.

An image measurement device acquires a first measurement region and a second measurement region on an image, acquires distance information corresponding to the first measurement region and distance information corresponding to the second measurement region, and computes a distance between the two regions. In a case where the first measurement region is displaced on the image, the second measurement region is displaced on a contour or a plane on the image, and a distance between the first measurement region after the displacement and the second measurement region after the displacement is computed. Thereby, distance measurement is able to be performed over a wide range without a complicated operation in the image measurement device for measuring a distance between two regions by using an image.
