The Tracksure monitoring system is part of the Remote Condition Monitoring Competition which is supported by the Rail Safety and Standards Board (RSSB), and Network Rail.
Every train on the British main line network is fitted with a GSM-R cab radio system, and Siemens produces one of the most widely-used devices. It is now possible to fit a Tracksure sensor card to the Siemens cab radio, and by monitoring vibrations,
t is possible to detect under-track voids and provide early warning of problems created by gaps that have developed between sleepers and ballast.
