Urgent warning: Landslide sensors may not work
19 Dec
Summary
- Train sensors failed to alert Network Rail to a sudden landslip.
- An Avanti West Coast train derailed near Shap, Cumbria, in November.
- Network Rail is urged to mitigate risks from failing landslide detection.
An urgent safety warning has been issued to the rail industry following a derailment in Cumbria where landslide monitoring equipment failed to detect a rapid landslip. The incident occurred on November 3rd when an Avanti West Coast train, traveling at 83 mph from Glasgow to London, struck debris on the tracks near Shap.
Investigators found that while the sensors registered minor earth movements hours before the crash, they were likely tipped over too quickly during the actual landslip to transmit an alert. Wireless signals also failed when sensors were buried. This failure highlights a significant risk, particularly during extreme weather events, as the equipment may not provide timely data for safety decisions.
Network Rail acknowledged the findings and stated they are working to implement the safety advice, enhancing sensor performance. The company has increased investment in earthworks and drainage, committing nearly £100 million over four years for the north-west England region, aiming to bolster railway safety against adverse weather conditions.
