launches fourth ultrasonic test train Network Rail


Network Rail’s director of engineering Steve Yianni explains how the organisation’s test trains help it with its number one priority – safety.

igh-tech ultrasonic scanning equipment on board Network


Rail’s test trains


can detect the smallest flaws in the track infrastructure, giving early warning of potential problems.


With three trains already working at full capacity, Network Rail has now launched a fourth, adding extra resilience too as now one can be taken out of use for servicing.


The trains use ground penetrating radar, ultrasonics and rail profile laser scanners to detect minute flaws in the track, irregularities in the ballast and voids below it up to two metres deep.


The rail profile scanner on the test trains, known as UTUs, uses laser technology to


compare the state of the railhead with a pre- programmed template to judge if the track is becoming worn out of shape, and in need of grinding.


Network Rail’s director of engineering Steve Yianni said: “Network Rail’s number one priority is safety and the addition of this unit to our fleet means we can measure the safety and quality of our railway to much higher standards.


“It also means we can keep our test trains running more reliably and at more times across the country. With this we can improve the quality of the ride for all our passengers, and make sure they reach their destination in complete safety.”


The new train, UTU-1, cost £700,000 and has more accurate positioning systems and an


improved ability to test the track. It can also be used at a higher speed, an important part of Network Rail’s plans for maintaining the network.


Most testing currently takes place at night at speeds of up to 30 mph. With further development and UTU-1, it is hoped to be able to test the track at 45mph.


Network Rail was keen to stress that these test trains do not replace traditional track walks by permanent way staff – although they do reduce the need for them. Instead, they direct the focus of track walks to areas needing inspection, saving time and money, and increasing the safety of the network.
