Abstract
The method is for checking the integrity of a section of railway track, comprised of two rails (1, 2) between which is placed a generator (3) or detector at one extremity and an impedance at the other extremity. A detector or generator (3) is arranged in a common mode connector (6). The method involves the following steps: generation of a signal of a given frequency and its application to the track section; capture and detection of the signal using a detector; and processing of the signal to made a deduction about the track integrity. An Independent claim is included for a corresponding installation for checking the integrity of a railway track section, especially for detecting a break in one of the rails.
