Claim 7:
8. A system for automatically detecting whether a vehicle entering a track section of a railway network and moving from a first subsection in direction to a third subsection is shorter than a predefined length L, the system comprising:
an evaluation unit;
a detector system configured for determining an occupancy state by the vehicle of the first subsection and of the third subsection of the track section, wherein the occupancy state is either “occupied” or “free”, said detector system further configured for detecting at a time T0 an entry of the vehicle on the first subsection and for reporting to said evaluation unit, from said time T0, the occupancy state of the first subsection and of the third subsection as a function of time, the first subsection being separated from the third subsection by a second subsection whose length is the predefined length L; and
said evaluation unit configured for receiving from said detector system the occupancy states as a function of the time and for determining from a temporal evolution of the occupancy states of the first and third subsections, whether the vehicle entering is shorter than the predefined length L, and if the vehicle has been determined to be shorter than the predefined length L, then said evaluation unit is configured to automatically notifying a control system in charge of controlling vehicle traffic on the railway network that the vehicle whose entry on the first subsection has been detected is a short vehicle.
