FIELD: physics.
SUBSTANCE: method comprises inspecting a portion of a railway line using a magnetic flaw detector mounted on a flaw detector car; identifying defects and structural components (bolt and welded joints of rails, metal rail plates etc), signals from which and positions of which are stored in a test card; using data on the structural components of the railway line for navigation during ultrasonic flaw detection of the same portion of the railway line; detailed analysis of objects identified by the magnetic flaw detector using an ultrasonic flaw detector; correcting the test card based on the flaw detection results.
EFFECT: high accuracy, quality and rate of detecting defects on rails.
