The rail industry has a continuing need for rapid, reliable methods of defect detection and characterisation that ideally can be deployed from a moving train. Most of the technology currently deployed concentrates on the head of the rail, but foot corrosion is also a concern, particularly in tunnels and at level crossings. Our spin-out company Guided Ultrasonics Ltd has produced a rail tester in collaboration with Railtrack/Network Rail (Guided Ultrasonics Ltd) This instrument is sensitive to defects in the whole cross section of the rail, including the foot. We have also worked on surface wave inspection of the head of the rail as an adjunct to existing methods.
