Abstract (en)
An apparatus for detecting presence at a railway track spot (1) of a metal object able to influence an integrity check of on board transmission equipment of a railway vehicle comprises a conducting loop (8) resembling a railway vehicle on board antenna with respect to shape and size and to be placed above the spot in similar relation thereto as a said antenna passing the spot. A member (9) generates an alternating current in the loop (8). Means (10) measures the impedance in the conducting loop and a unit (11) compares the impedance value measured with a predetermined impedance value for a measurement with reference structures according to established standard rules influencing the impedance and consider a detected degree of deviation of said impedance values as a presence of a said metal object at said spot able to influence an integrity check of on board transmission equipment of a railway vehicle.
