FIELD: transport.
SUBSTANCE: invention relates to flaw inspection and nondestructive checks. Invention consists in using pulses of surface electromagnetic waves radiated forward and/or backward relative to train direction, registering reflection of said pulses from irregularities of the track and defining type of track and/or rolling stock defects from character of said irregularities.
EFFECT: detection of dangerous macroscopic defects at distance exceed stopping distance and registration of derailment.
