Estimating the term…
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.
