On the hottest day of the year, with temperatures soaring above 33C, passengers were forced to evacuate trains near Loughborough Junction in south London due to a fault that halted services. The incident, which occurred on Saturday, left many stranded without power or air conditioning for up to two hours, prompting apologies from Thameslink and Network Rail.

Train Disruption and Passenger Evacuation

The fault, which affected three trains outside station platforms, led to a challenging evacuation process. Angela Lewis, a passenger bound for Gatwick, described the experience as "a bloody nightmare," noting that some travelers missed flights due to the disruption. Thameslink stated that personnel were deployed from across Sussex and Kent to ensure a safe evacuation along the tracks. Despite the efforts, passengers expressed frustration on social media, questioning the necessity of the prolonged wait in overheated carriages.

Heatwave and Health Warnings

The UK Health Security Agency issued an amber heat-health alert, cautioning vulnerable populations about the risks associated with the extreme heat. The London Ambulance Service anticipated a surge in emergency calls, reflecting the strain on public health resources. Researchers from the London School of Hygiene and Tropical Medicine and Imperial College London estimated that the heatwave could result in 129 excess deaths in London alone, with a broader estimate of 570 excess deaths across England and Wales.

Weather Alerts and Future Implications

The Met Office recorded a provisional temperature of over 33C in Surrey, marking the hottest day of the year. A yellow warning for thunderstorms was also issued, covering parts of south-east Scotland, Yorkshire, the Midlands, and Wales. The warning included potential flash flooding, with up to 40mm of rain expected in less than two hours.
