Abstract
A system and a method automatically detect whether a vehicle entering a track section of a railway network is shorter than a predefined length. The method includes detecting at a time T0 an entry of the vehicle on a first track subsection. From the time T0, the occupancy states of at least a first subsection and a third subsection are determined in dependence on the time. The occupancy state is either “occupied” or “free”. The occupancy states for at least first and third subsections is reported to an evaluation unit at least until the occupancy state of the first subsection is “free”. The reported occupancy states determined for the at least first and third subsections are processed by the evaluation unit, and from a temporal evolution of the occupancy states of the first and third subsections, it is determined whether the entering vehicle is shorter than the predefined length.
