FIELD: transport.
SUBSTANCE: invention relates to track safety control and serves for remote detection of changes in track conditions caused by rail structure faults and occurrence of dangerous objects in groundwork. Proposed method comprises recording of vibroacoustic pulses in rail resulted from interaction of wheel pairs with rail joints at equal opposite distances therefrom. Signals registered on train passing said rail joints are filtered out and accumulated. Note here that after passage of first train over known-good track said signals are converted to maximum affinity to conserve parameters of correcting circuit. In passage of the next train of track section - signal generator result of comparison is compared with preset threshold. In case it is exceeds decision is made about availability of affected track ahead of running train.
EFFECT: higher reliability of remote detection in real time conditions.
