Heat Triggers Derailments

Experts warned that extreme heat may have caused rail expansion and buckling, possibly contributing to the derailments.

History

Historical Context

In August 2003, a European heatwave broke temperature records, buckled rail tracks in France and the United Kingdom and killed over 72,000 people across Europe, leading SNCF to cancel 1,200 trains and Network Rail to log over 300 buckling incidents. The 2026 derailments near Lewes and Wickford, investigated by Transport Secretary Heidi Alexander and the Rail Accident Investigation Branch, underscore the need for heat-resilient infrastructure.
