RAILWAY DETECTION SYSTEM, RAILWAY INFRASTRUCTURE AND METHOD FOR DETECTING THE PRESENCE OF A RAILWAY VEHICLE

Railway detection system for detecting the presence of a railway vehicle on a railway track section comprising at least two rails, the railway track section comprising a first end and a second end opposite to the first end in a longitudinal direction of the railway track section, the railway detection system comprising a track circuit system comprising a signal generator electrically coupled to the first end of the railway track section, the signal generator being configured for generating a first track circuit signal to be injected into the railway track section at the first end, wherein the signal generator is adapted togenerate a first component of the first track circuit signal comprising at least one DC pulse;generate a second component of the first track circuit signal, andadd the first and the second component so as to obtain the first track circuit signal.
