The present invention provides a braking system (11) for braking a train. The system comprises an electronically controlled pneumatic brake network (ECP) and a brake activation unit (14). The brake activation unit provides status reports regarding the condition of the ECP and comprises at least one sensor for monitoring one or more properties of the ECP, and at least one venting means adapted to vent the pressure from a brake pipe (21). The system also comprises a telecommunication network (15, 17, 19) adapted to communicate with the brake activation unit. The brake activation unit can be activated using the telecommunication network to vent the pressure from the brake pipe, causing the train to brake.

A train control apparatus includes a setting reception unit that receives setting information regarding a temporary speed limit section and a speed limit. A control unit generates temporary speed limit information for the trains. A communication unit transmits the temporary speed limit information to the trains. If information regarding all temporary speed limit sections cannot be included in the temporary speed limit information, the control unit includes, in the temporary speed limit information, information regarding a specified number of temporary speed limit sections located on a traveling direction side, and changes a speed limit in one or more temporary speed limit sections included in the temporary speed limit information on the basis of a speed limit set in a temporary speed limit section that is adjacent to a temporary speed limit section included in the temporary speed limit information, and is not included in the temporary speed limit information.

Disclosed is a method, system, and computer readable medium including program instructions for controlling the braking of one or more vehicles in a vehicle system positioned for unloading/loading of cargo. The vehicle system includes a designated head-end and a tail-end and each of the one or more vehicles is equipped with an electronic braking system in communication with a central control via a communication network spanning across the vehicle system. A dynamic unloading/loading braking profile can be set on at least one electronic braking system on at least one vehicle. During unloading/loading of the cargo from one or more vehicles in the vehicle system, the braking on at least one of the vehicles in the vehicle system is controlled via the dynamic unloading/loading braking profile.

Systems and methods are provided for decentralized rail signaling and positive train control. A decentralized train control system may include a plurality of wayside units, configured for placement on or near tracks in a railway network, and one or more train-mounted units, each configured for use in a train operating in a railway network that support use of the decentralized train control system. Each train-mounted unit may configured to receive communicate with any wayside unit and/or train-mounted unit that comes within range, with the communicating including use of ultra-wideband (UWB) signals, and for generating control information based on the UWB signals, for use in controlling one or more functions associated with operation of the train.

In one aspect of the present disclosure, an apparatus for locating a mobile railway asset is provided that includes a power source, GNSS circuitry configured to utilize electrical power from the power source to receive GNSS data, and a controller operatively coupled to the power source and the GNSS circuitry. The controller has a power saving mode wherein the controller inhibits the GNSS circuitry from receiving GNSS data and a standard accuracy mode wherein the controller permits the GNSS circuitry to receive GNSS data for a first time period. The controller has a higher accuracy mode wherein the controller permits the GNSS circuitry to receive GNSS data for a second time period longer than the first time period, and subsequently across multiple instances, in order to collect more GNSS data that can be qualified, filtered, sorted, and averaged to produce a more accurate result.

A computer-implemented method comprises: receiving, at a first one of the first electronic devices, a first wireless signal transmitted by a second electronic device attached to a vehicle; transmitting, from the first electronic device, a second wireless signal, wherein the second electronic device determines a location of the vehicle along the transportation pathway according to the second wireless signal; receiving, at the first electronic device, a third wireless signal transmitted by a second electronic device, wherein the third wireless signal identifies the determined location of the vehicle; and transmitting, from the first electronic device, a fourth wireless signal, wherein the fourth wireless signal identifies the determined location of the vehicle, wherein other ones of the first electronic devices wirelessly relay fifth wireless signals along the transportation pathway, wherein the fifth wireless signals identify the determined location of the vehicle.

The present invention includes an on-board control apparatus that generates train position information using ground coil position information and train speed information and outputs the train position information, and a ground control apparatus that receives the train position information outputted by the on-board control apparatus, identifies a position of a train using the train position information and stored track information, generates train control data having a size corresponding to the identified position of the train, and outputs the train control data toward the train.

In one example, a wayside device monitoring system is provided. The system may include a wayside device and a controller. The wayside device may detect one or more operating parameters of a vehicle in a vehicle system moving over a route segment. The controller can receive information from the wayside device regarding at least the one or more operating parameters detected, and can control movement the vehicle directly or indirectly based at least in part on the received information.

A system and a method for monitoring pressure inside a railway vehicle comprise a carriage pressure detection device, a control device, and an alarm device. The control device is configured to receive and process a pressure signal collected by the carriage pressure detection device, perform calculation on and analyze the collected data, and transmit an alarm signal to the alarm device as an alarm when a preset alarm condition is met. When a pressure protection device fails, pressure changes inside the vehicle are monitored in real time by the carriage pressure detection device functioning independently of the pressure protection device.

The current invention relates to a method for monitoring the configuration of a train, the train comprising a plurality of railway vehicles coupled to each other, each of the railway vehicles comprising a monitoring module on each end, each monitoring module comprising a unique identifier, a low power radio configured to have a range within free space of at least 3 m and at most 10 m, a memory and a communication means to wirelessly communicate with a processing unit. The inventions also relates to a device for monitoring the configuration of a train.
