In one embodiment, a method includes receiving first Light Detection and Ranging (LiDAR) data associated with a railroad environment, extracting an asset from the first LiDAR data associated with the railroad environment, and superimposing the asset into a spatial model. The method also includes receiving a field indication associated with a modification to the railroad environment and modifying the spatial model in response to receiving the field indication associated with the modification to the railroad environment. The method further includes receiving second LiDAR data associated with the railroad environment and comparing the second LiDAR data to the modified spatial model.

To provide a wireless train control system that can perform a stable operation. The wireless train control system controls a wireless-control compliant train following a wireless-control noncompliant train by a ground control device. A stop limit point of the wireless-control compliant train is set by a track circuit in which a tail end position of the wireless-control noncompliant train is present. By using a track-circuit state signal indicating that the track circuit is turned on or turned off and a time-element-added track-circuit state signal indicating turn-off at a timing delayed by a set time after the track-circuit state signal has indicated turn-off, when the track-circuit state signal indicates turn-off and the time-element-added track-circuit state signal indicates turn-on, it is determined that turn-off indicated by the track-circuit state signal is caused by the wireless-control compliant train that is a train itself being present, and the stop limit point is not updated.

A train control system configured to automatically execute and ensure compliance with all requirements for radio blocking. A radio blocking module of the physical train control system of a lead train retrieves and displays the appropriate clearance points for acceptance by the train driver of the lead train. Once accepted, the clearance points are transmitted to a trailing train for display and acceptance by the train driver of the trailing train. An accepted clearance point is passed to the train control system for use as the next destination point for navigation purposes. The train control system can also electronically log all acts to comply with applicable radio blocking requirements.

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.

Disclosed is an independent system for the inspection, monitoring and surveillance of long infrastructure and the environment thereof, which is based on a movable device with systems for propulsion and control of the device, power and recharging systems and navigation and positioning systems, and which is able to inspect the infrastructure and communicate with a remote control, the system being formed by an autonomous mobile device (DM) including rolling elements (R), and a grooved auxiliary line (LA) consisting of a cable comprising a guiding groove (RA).

A condition monitoring system (CMS) for vehicle bearing units, including at least one condition monitoring unit (CMU) for measuring at least one operating parameter of one bearing unit and a control unit for receiving and processing signals from the CMU. The control unit is configured to activate/deactivate the CMU(s) upon reaching at least one predetermined waypoint stored in a waypoint memory of the control unit. The CMS can be equipped with a waypoint setting unit for setting the at least one waypoint at which the CMU(s) shall be activated/deactivated and to store the waypoint in the waypoint memory. The waypoint setting unit processes route data includes data on at least a curviness of at least one route intended for vehicle travel. The processing includes extracting at least one route section within the curviness of the route within a predetermined range and setting the waypoint(s) within the extracted route section.
