The blistering heatwave gripping parts of the UK has prompted Great Western Railway (GWR) to make significant service adjustments, including speed restrictions and potential cancellations, to safeguard passengers and protect rail infrastructure. The changes primarily affect key routes between London Paddington and destinations like Bristol Temple Meads, South Wales, and the West Country.
Passengers planning to travel on these lines are urged to check their journey details before departure, as last-minute changes may occur. GWR is working closely with Network Rail to manage the impact of high temperatures on the rail network.
Network Rail implements speed restrictions when track temperatures rise significantly due to the risk of steel rails buckling under intense heat and causing derailment. Reducing train speeds mitigates this risk, making it a standard safety protocol during heatwaves that have become more frequent and severe in recent years.
The Met Office has issued various weather warnings across the UK, with amber warnings for extreme heat currently in place for parts of England and Wales. Temperatures are expected to reach up to 30-32 degrees Celsius in some areas, while yellow warnings cover other regions, including Scotland and Northern Ireland, where conditions are also unseasonably warm.
GWR advises passengers to carry water, wear light clothing, and be aware of potential delays or disruptions. Those choosing not to travel due to the heat may be eligible for a refund or to change their ticket without charge, depending on the specific circumstances and ticket type. Further information is available on the GWR website.
The hot weather is expected to persist for several days before gradually easing towards the end of the week. The rail industry will continue to monitor conditions closely and adjust services as necessary to prioritise safety and minimise disruption where possible.
