Tiny device ‘could prevent rail disasters’

A father and son team has created a miniscule device that could help prevent rail disasters.

The gadget, dubbed Microlog, monitors the stresses and strains to which train axles are subjected. Any abnormal data could reveal a developing problem on the track, providing a crucial prediction of imminent catastrophic failure.

The device weighs less than ten grams, and is less than a third of the size of a matchbox. Despite its diminutive dimensions it boasts a four megabyte memory, a powerful 16 byte microprocessor, as well as satellite and mobile phone technology. Some of the components are so small they are barely visible to the human eye.

The Microlog records all the relevant data, and harnesses the satellite technology to detect the exact location of the problem. The data are sent via the mobile phone network to a remote computer for analysis using a highly sophisticated software package. Finally the train operator is alerted if there is any need for preventative action.

Dr Jarek Rosinski at the University of Newcastle developed the gadget, alongside his 18-year-old son, Martin, who is studying at the university. Dr Rosinski explains that data loggers have been used for over 20 years, but have previously been limited in applications because of their large size.

‘Microlog is unique because of its miniature size, which allows us greater flexibility and means we can to fit it to smaller components such as train axles. The computer software which accompanies it is also extremely sophisticated.’

Microlog can also be remotely accessed and reprogrammed using a short-range radio, the internet, or via the GSM network.

The gadget was developed at the Stephenson Centre, which was officially opened by Science and Innovation Minister Lord Sainsbury last Friday. The venture is inspired 19th Century entrepreneur, Robert Stephenson, who built the Rocket locomotive in a nearby Newcastle factory.
