Abstract: 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 traveling 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 traveling along respective portions of the section.

Abstract: A train detection system for a railway track defines a first lateral side and a second lateral side opposite the first lateral side. Two cameras are arranged along the railway track spaced apart from each other. Each camera is placed on either the first lateral side or the second lateral side. The system includes at least one passive target. Each of the passive targets is placed within the field of view of at least one of the cameras and on the opposite lateral side of the railway track with respect to the at least one of the cameras in whose field of view the respective passive target is placed. The system also includes at least one controller adapted to recognise the passive target in the images provided by at least one of the cameras to the controller to determine whether a train is located on the railway track.
