The enquiry into the Hatfield rail crash of October 2000 revealed that nearly two years earlier, engineers had identified a form of fatigue called gauge corner cracking in the rail which eventually broke and caused the crash.
Researchers at the University of Warwick’s Department of Physics have developed a technique to detect and measure gauge corner cracking and other rail defects by using ultrasound waves.
A short film about the research is available on the Research-TV website – the link above will take you to more information
