A system and method are for controlling a train traveling along track blocks. A first signal transmitter is installed at a first track block and transmits, using a predefined range of transmission frequencies, first signals for detecting when the train enters the first track block. A second signal transmitter is installed at an adjacent second track block and transmits, using a predefined range of transmission frequencies different from the predefined range of transmission frequencies used by the first signal transmitter, second signals for detecting when the train enters the second track block. One or more signal receivers on board of the train are configured to receive the transmitted first and second signals, and an onboard controller is configured, based on signals supplied by the one or more receivers indicative of the first and second signals received, to identify when the train enters the first or second track blocks.

Systems and methods are provided for ultra-wideband (UWB) based navigation of arbitrary paths based on reference markers. A train-mounted unit may be configured to, when deployed on a train, communicate with any wayside unit, from a plurality of wayside units configured for placement on or near tracks in a railway network, that comes within communication range of the train-mounted device, with the communicating including use of ultra-wideband (UWB) signals, and generate based on communication, train location information, with the generating of the train location information including determining based on processing of communicated UWB signals with at least one wayside unit, range to the at least one wayside unit, and determining based on the determined range to the at least one wayside unit, change in range (R) to the at least one wayside unit and change in location (L) on a track in the railway network.

Methods and systems for visualizing event data associated with operations of a classification yard and replaying the visualized event data in a graphical user interface. In embodiments, graphical representation of the classification yard, including its components (e.g., devices and track segments) is generated. A set of event messages is extracted from an event log, and analyzed to determine a component associated with each event message. A visual representation is generated for each event message in the set of event messages and overlaid onto the graphical representation of the component to which the event message is associated. The overlaid visual representations are replayed in a sequence according to timestamps of the visualized event messages.

A method and system are for estimating forces in rails of a railway line which are due to the temperatures of the rails. Values of the electrical resistance of one rail of a railway track section are calculated. Based on the calculated values of the electrical resistance for the rail, corresponding values of the temperature of the rail can be estimated, and based on the estimated values of the temperature of the rail, estimated values of forces acting in the rail due to the temperature values can be estimated.

The invention relates to a train control method based on mobile authorization verification, which compares driving permission sent by a vehicle-mounted device to a ground trackside device with driving permission calculated by itself, and outputs the strictest driving permission. Compared with the prior art, the invention has the advantages that the correctness of mobile authorization calculation is improved, and the safety of train stop points is ensured.
