Accord including a first electrical conductor configured for connecting electrically to the overhead line of the segment of rail track, a second electrical conductor configured for connecting electrically to ground and/or a return line of the segment of rail track, a switch configured to enable and disable a connection between the first and second electrical conductors, control means configured to activate and deactivate the switch, and communication means configured for wireless communication with a remote communication device, for receiving a control signal from the remote communication device and for accordingly actuating the control means for activating and deactivating the switch, or for blocking the switch, wherein the communication means are configured for communication over a public telecommunication network.

The present invention relates to a heavy freight train marshalling device and marshalling method, and an electronically controlled pneumatic brake system; the latitude and longitude data of the carriage control unit is acquired by a Beidou positioning module; the first-vehicle state data of the carriage control unit is acquired by detecting a first-vehicle identification terminal; and, the carriage control units only need to transmit the acquired location data and the first-vehicle state data to the HEU via communication modules. Accordingly, the number of communication messages between the carriage control units and the HEU is decreased, the complicated process of connecting the carriage control units to or disconnecting the carriage control units from a switchable load is omitted, the marshalling time is shortened, and the complexity of marshalling is reduced.

A technique comprising: detecting at a first radio node a first signal indicating the number of hops at which a second radio node that transmitted the first signal first detected a second, earlier signal; and deciding whether to transmit said first signal onwards from said first radio node based at least partly on (i) a direction indicator in said first signal, (ii) a comparison of the respective numbers of hops at which said first and second radio nodes first detected said earlier second signal, and (iii) the result of a search at said first radio node for onwards transmission of said first signal by another radio node in the direction indicated by said hop-count number direction indicator.

Systems and methods for alerting rail workers of an oncoming rail vehicle are described. The system and method provide for a vehicle alert device on a rail vehicle. The vehicle alert device has two radios operating at different frequencies. Further provided is a personal alert device worn by a rail worker. The personal alert device has two radios operating at different frequencies. The frequencies of the radios in the vehicle alert device and of the radios in the personal alert device correspond to one another. One of the radios in the vehicle alert device and one of the radios in the personal alert device operate on the same frequency and perform ranging functions. The other radio in the vehicle alert device and the other radio in the personal alert device operate at the same frequency and provide for data communication between the rail worker and the rail vehicle.

The monitoring system comprises an axle traveled distance module connected to at least one transport unit monitoring system and adapted to determine, for each of the axle identifiers detected by at least one of the transport unit monitoring systems, an axle traveled distance increment during a corresponding acquisition time period in function of transport unit traveled distance increments during this acquisition time period of the at least one transport unit monitoring system that detected this axle identifier during this acquisition time period.

A sensor device for a vehicle that traveling on a predetermined route, particularly a rail vehicle, includes a plurality of sensors configured to detect movement of the sensor device and/or physical variables of an environment of the sensor device, and to issue corresponding measurement values. The sensors include magnetic sensors for detecting orientation and/or pressure sensors and/or real time clocks. A data storage unit is configured to store reference measurement values for the sensors, relating to predetermined positions on the predetermined route. A computing unit is configured to compare the measurement values issued by the sensors with the stored reference measurement values and, when the measurement values issued by the sensors coincide with the reference measurement values, to issue, as a current position of the sensor device, a position corresponding to the respective reference measurement values. A corresponding vehicle and a corresponding method are also provided.

A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.

A satellite positioning location based control and monitoring system for light rail transit systems which enables transit personnel to track vehicle positions, progress and non-vital signals as light rail vehicles travel through their routes while eliminating the capital and maintenance costs associated with embedded light rail transit monitoring systems.

A visual diagnostic system for a rail vehicle having multiple assets is disclosed. The visual diagnostic system may have a data interface configured to receive a data stream from a wayside unit. The data stream includes values of a plurality of parameters measured made by the wayside unit. The data interface may also be configured to receive geo-information and configuration-information. The system further includes a memory device configured to store the data stream and a controller configured to determine, from the geo-information and the configuration-information, a geographic location of each of the multiple assets. The controller is further configured to determine prognostic information associated with an operational status of each of the multiple assets. The controller may further render for display in a user interface a visual representation of the rail vehicle with the prognostic information for each asset of the rail vehicle.
