Train detection security system (1) and corresponding method, comprising one or more sensor units (2a, 2b,....) arranged for being fixed to a rail (10a, 10b), each arranged for detecting a first signal (s1) induced by a moving train (6) and propagated through the rail. A control unit (3) comprising a signal processor (31) arranged for receiving first sensor output signal (s1') representing the first signal (s1) from each of the one or more sensor units (2a, 2b,....), processing the first sensor output signal (s1') and generating a train warning signal (s10) representing characteristics of the moving train (6) based on characteristics of the first sensor output signals (s1'). The signal processor (31) comprises an envelope detector (32) and an envelope signal comparator (33) wherein the computer implemented signal processor (31) is arranged for generating a train warning signal (s10) indicating an approaching train (6) when the envelope signal (s1'e) has an increasingly higher amplitude than a predefined envelope signal (s1'p) over the time segment (T).
