Abstract (en)
[origin: EP2112045A1] One or several balises (1, 2) used to transmit telegrams to passing railway trains and a lineside electronic unit (8) connected to the balises (1, 2) bear alternating current fed loops (4.1, 4,2, 4.L, 4.R) sensing a signal representing the underside structure of a passing train (9). The signal is used for track occupancy detection and train length determination. In a preferred embodiment, the signal is provided by the loop impedance variations induced by permeable material of a passing train's underside.
