20220348242 · 2022-11-03 ·

A method is provided for operating a railway network having a number of trains, the method comprises operating a scheduling machine that is in communication with the railway network over a data communication system, to receive time separated state data defining states of the railway network at respective times. The scheduling machine accesses a model of the railway network that is stored in an electronic data source. The model defines locations in the railway network that allows for passing of trains and paths for journeys of each of the trains. The method includes operating the scheduling machine to apply the state data to the model to determine, at each of the respective times, controls associated with each trains' path for each of the trains. The scheduling machine is operated to determine the controls by optimizing a objective function for the trains, such as minimizing total travel time of the trains, taking into account the locations in the network, positions of the trains and paths of each of the trains. The controls are transmitted, via the data communication system, to control movement of the trains, for example by operation of railway network switches (points) and signal lights, through the railway network based on the controls.

11479279 · 2022-10-25 · ·

An on-board device is configured for reading a telegram of a balise installed at a point along a route followed by a guided vehicle in which the on-board device is to be installed. The on-board device includes a receiver having an antenna for picking up the telegram transmitted by the balise and delivering a reception signal to a processing unit. The processing unit is configured for processing the reception signal in order to read the telegram sent by the balise. A test component is configured for adding a test signal to the reception signal before its processing by the processing unit. The test signal is configured to act as a noise for limiting a sensitivity of the receiver, making it therefore impossible to read a cross-talk signal. A method for protecting the on-board device from cross-talk is also provided.
