A system and method for inspecting a railway track using sensors oriented at an oblique angle relative to a rail vehicle on which the system is traveling. The orientation of the sensors allows for different data to be gathered regarding a particular rail including rail design specifications (gathered based on manufacturer markings detected and analyzed by the system), rail seat abrasion values based on direct measurement of rails from the oblique angle, and other analysis of rail features including joint bars, rail welds, bond wires, rail holes, and broken rails. The use of an air blower, ducts, and one or more air distribution lids over the sensors helps remove debris from blocking the sensors and structured light generators.

The invention relates to a method of controlling a track maintenance machine, particularly a switch tamping- or universal tamping machine, which moves along a track and has working units, particularly a tamping unit and a lifting unit, which are adjustable relative to a machine frame, wherein position data of track objects, particularly sleepers, rails and optionally obstacles, are recorded by means of a sensor device in front of the working units in a working direction, and wherein operating positions of the working units are determined for a working operation at a track location. In this, prior to actuation of the working units, the determined operating positions of the working units are displayed by means of a display device, wherein, prior to carrying out the working operation, the operating positions of the working units can be changed by means of control elements. As a result of the display of the determined operating positions prior to the working operation, an operator is enabled to recognize possible misalignments before these become effective.

A system for railroad directive management is presented. The system can receive a myriad of data related to a directive, track segments, and/or vehicle events on the track and/or track segments. Vehicle- and/or event-specific data can be compared with one or more thresholds, including force thresholds, temporal thresholds, environmental thresholds, and/or event thresholds to determine whether and what kind of directive modification should be instantiated. Specialized algorithms can be implemented to trace vehicle paths along the track to determine whether directive-related segments are traversed, and specialized clustering algorithms can be utilized to cluster data unique to a particular segment on a per-segment basis. The system can be integrated with existing track infrastructure and can further generate alerts to notify coupled systems and/or personnel of directives and/or modification thereof.
