Network Rail, as the infrastructure manager of Britain’s railways, continue to review and update the monitoring techniques they use to detect precursors for earthwork failures on railway embankments they manage. These enhancements are informed by geotechnical experts and include increasing the use of remote sensing, photogrammetry, CCTV, distributed acoustic sensing and inclinometers. These are among other tools to enable Network Rail engineers to target measures to reinforce slopes, add protection and improve resilience in the long term.
