History

Historical Context

In August 2003, a UK heatwave raised temperatures about 15 °C above normal, causing rail expansion that buckled tracks and forced Network Rail to impose emergency speed restrictions, resulting in roughly 12,000 delayed journeys and three temporary line closures. On 14 August 2026, a similar heat-induced rail deformation led to a Greater Anglia derailment near Wickford, highlighting ongoing vulnerability of the rail network to extreme heat.
