Abstract (en)
A railway signalling system is disclosed in which there is a combination of fixed block signalling with direct communication between separate trains or vehicles to achieve inter-vehicle spacing. The fixed block signalling prevents more than one train (or vehicle) from transmitting and more than one train (or vehicle) from acting upon communications relative to a given area or portion of line.
