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.

System and method for controlling a train travelling along a railway line

A wayside to railway vehicle communication method including providing a first wayside device with a transmitter device capable of transmitting a data packet message to a railway vehicle travelling along a section of a railway track, through an electric waveform put into a rail of the section, and sending at least one message from the transmitter device to the railway vehicle, wherein the at least one message corresponds to the conversion of the data packet into a modulated electric waveform, the data packet including several data bits providing information relative to a plurality of speed limits the railway vehicle has to respect while travelling along respective portions of the section.

Wayside to railway vehicle communication method and device

The invention concerns a method for determining the location of a railway vehicle comprising a first navigation module determining a regular resolution position of the railway vehicle with a first accuracy measurement and a second navigation module determining a high resolution position of the railway vehicle with a second accuracy measurement, using the received signals. The method comprises the steps of determining a first confidence area around the regular resolution position, based on the first accuracy measurement, of determining a second confidence area around the high precision position, based on the second accuracy measurement, and of assigning a weight of confidence to the knowing of the actual location of the railway vehicle, by analyzing the overlay of the first and the second confidence areas and the first and the second accuracy measurements.
