United KingdomBritain's railways have experienced multiple heat-related incidents this summer, including two derailments that injured 30 people near Lewes and caused no injuries at Wickford. These issues occurred during one of the hottest and driest summers on record, straining a network designed for a cooler, wetter climate. Heat causes steel rails to expand, leading to potential buckling due to limited space for expansion. Network Rail noted the summer presented 'exceptional challenges' to the railway. Engineers explain that while tracks can operate up to 46°C, rails have reached 51°C, increasing risks. Drought conditions have dried the soil beneath tracks, weakening support and exacerbating problems when heavy trains pass. Some infrastructure dates back to the 1800s, highlighting aging components. Experts suggest methods used in hotter climates, such as pre-stressing rails, could help mitigate these issues.
