Southeastern has issued a stark warning as the UK prepares for its hottest day ever. Temperatures forecast to reach 38°C in some areas will bring significant disruption to rail services, with speed restrictions on tracks likely to buckle under extreme heat.
The Met Office's amber warnings cover much of England and parts of Wales, while red alerts are issued for central, northern, eastern, and south-eastern regions. Southeastern serves London and the South East, areas that will feel the full force of this record-breaking heatwave.
Speed restrictions mean trains must run slower to prevent damage, increasing journey times and leading to cancellations. Passengers have been advised to check their journeys before setting off and allow extra time. They are also urged to stay hydrated by carrying water, wearing light clothing, and seeking shade when possible.
The impact will be felt across the UK, with England's red warning areas expected to see temperatures rise to 38°C or higher. The amber warning stretches into eastern Wales, where temperatures are still likely to exceed 30°C. Scotland and Northern Ireland will experience warm conditions but not as extreme.
As health bodies stress hydration and avoiding strenuous activity during the hottest periods, the heatwave poses a significant challenge for infrastructure designed for milder climates. Southeastern's safety-first approach means trains will run slower, causing considerable inconvenience to commuters and travellers. Passengers are advised to reconsider non-essential journeys or make alternative arrangements.
