Systems and methods are provided for worker protection system with ultra-wideband (UWB) based anchors. One or more wayside units placed on or near a track may be configured to form a work zone network, based on ultra-wideband (UWB) communications, corresponding to a work zone in an area surrounding or in proximity to the one or more wayside units. When the work zone network is formed, at least one wayside unit of the one or more wayside units may be configured to obtain ranging information to a train traversing the track, based on communications of UWB signals with at least one train-mounted unit deployed on the train, and the one or more wayside units are configured to generate, based on the ranging information, notifications relating to the train and/or the work zone.

External sensor data is efficiently recorded without changing a resolution or a sampling rate. In a data recording device, an acquired data property storing unit stores, as a data property, an external environment in which external sensor data is to be recorded, an external sensor data property recognizing unit recognizes, as a data property, the external environment corresponding to the external sensor data, a data recording necessity determining unit determines, based on the data property recognized by the external sensor data property recognizing unit and the data property stored in the acquired data property storing unit, whether the external sensor data is required to be recorded, and a data recording unit records the external sensor data when it is determined by the data recording necessity determining unit that the external sensor data is required to be recorded.

A method may include determining time-variable risk profiles for plural separate vehicle systems that are remotely controlled by operators that are located off-board the separate vehicle systems. The time-variable risk profiles represent one or more risks to travel of the separate vehicle systems. The method may include assigning the operators to remotely monitor or control the separate vehicle systems during the trips based on the time-variable risk profiles. The operator assigned changes with respect to time while the one or more separate vehicle systems is moving along one or more routes during the trip. A system may include one or more processors that may determine time-variable risk profiles for plural separate vehicle systems that are remotely controlled and assign the operators to remotely monitor or control the separate vehicle systems during the trips based on the time-variable risk profiles.

Provided is a computer-implemented method for determining a communication status in a train consist operating in a distributed power system, the train consist including a lead locomotive and a plurality of remote locomotives. The method includes, for each remote locomotive of the plurality of remote locomotives that receives the command message directly from the lead locomotive, setting the message source indicator of the remote locomotive to a first state representative of a direct receipt of the command message, incrementing the message source counter for each response message received by the remote locomotive from other remote locomotives in which the respective message source indicator is set to the first state, generating a response message including a value of the message source indicator and a value of the message source counter, and transmitting the response message. A system and computer program product are also disclosed.

A cyber security system for providing security to a railway, the system comprising: a data monitoring and processing hub; a network comprising a plurality of data collection agents synchronized to a same network clock and configured to monitor railway infrastructure devices and onboard devices of rolling stock having a train communication network (TCN), and forward monitored data to the hub for processing by the hub to detect anomalies in railway operation that are indicative of a cyber-attack; at least one anonymizer configured to scrub information items from data that the hub receives from a data collection agent of the plurality of data collection agents which may be used to identify the cyber security system or the railway for which the system provides security.

A device and method for detecting a location of an arc event between a power bus and a coupler of an electric vehicle monitors an interface between the power bus and the coupler for the occurrence of an optical event. A determination is made if an arc event occurred based on the optical event, and upon determining the occurrence of an arc event at least one of a time the arc event occurred or a position of the electric vehicle at the time the arc event occurred is recorded.

An apparatus and a method for increasing the movement speed of the rail vehicle while carrying out measures for controlling weeds on track systems. A rail vehicle equipped with an apparatus for increasing the movement speed of the rail vehicle while carrying out measures for controlling weeds on track systems.

Systems and methods are provided for worker protection system with ultra-wideband (UWB) based anchors. One or more wayside units placed on or near a track may be configured to form a work zone network, based on ultra-wideband (UWB) communications, corresponding to a work zone in an area surrounding or in proximity to the one or more wayside units. When the work zone network is formed, at least one wayside unit of the one or more wayside units may be configured to obtain ranging information to a train traversing the track, based on communications of UWB signals with at least one train-mounted unit deployed on the train, and the one or more wayside units are configured to generate, based on the ranging information, notifications relating to the train and/or the work zone.

A method and associated system for determining a maintenance status for a pantograph arranged on a vehicle and/or a contact wire intended to be in electrical contact with the pantograph. Monitoring at least longitudinal, vertical or lateral accelerations of the pantograph. Detecting an acceleration pattern based on the monitored accelerations of the pantograph. Determining accelerations in a direction above a predetermined value in the detected acceleration pattern. Determining a maintenance status for the pantograph and/or the contact wire based on the detected acceleration pattern, and wherein the maintenance status indicates a level of wear on the pantograph and/or the contact wire.

This disclosure is generally directed to systems and methods for determining a passage status of a train through a railroad crossing. In an example method, a railroad crossing status detector system provided in a vehicle may determine that a train is approaching the railroad crossing. The determination is made by evaluating a first detection signal received from a first train detection apparatus located on one side of the railroad crossing. The railroad crossing status detector system may then evaluate a second detection signal received from a second train detection apparatus located on the other side of the railroad crossing and determine that the train has traveled past the railroad crossing. The system may also evaluate one or both detection signals to determine whether the train is currently located at the railroad crossing or is backing up after traveling at least partway across the railroad crossing.
