FIELD: railroad facilities.
SUBSTANCE: method of complex rail diagnostics relates to control and measuring devices for checking the condition of railway tracks and can be used for testing a railway track by a complex of non-destructive testing tools, including for detection of microcracks on the rail head running surface. Method comprises installing, in known relative positions, devices for: defectoscopy, measurement of unevenness and video surveillance of rails, moving the vehicle along the railway tracks, constant measuring the condition of the railway tracks by all devices and preserving the results obtained. When detecting sections of railway tracks with surface defects or irregularities, images of these sections of the railway track are fixed with illumination at different angles, most contrasting with respect to defects video frames are identified and the are used in a joint analysis to assess the degree of development of microcracks and other surface defects.
EFFECT: as a result, the reliability of detecting microcracks on the rail head surface increases significantly while reducing the amount of recorded information.
