UK Heatwave Causes Major Train Delays Amid Safety Concerns
Published 30 June 2025
Highlights
- The UK heatwave has led to speed restrictions on major train lines, including the London to Brighton route.
- Temperatures are expected to reach 34C, with track temperatures nearing 60C, causing potential rail buckling.
- Network Rail has implemented speed restrictions to ensure safety, resulting in fewer trains and longer journey times.
- Passengers are advised to check schedules on the National Rail website and consider working from home if possible.
- The restrictions are set to remain in place until 10pm on Tuesday, affecting Southern, Thameslink, and GWR services.

Headline: UK Heatwave Causes Major Train Delays Amid Safety Concerns
As the UK grapples with a significant heatwave, rail passengers are facing delays and disruptions on key routes, including the London to Brighton line. With temperatures expected to soar to 34C (93F) in the South East, Network Rail has imposed speed restrictions to mitigate the risk of track buckling, which could lead to severe safety issues.
Heatwave Impact on Rail Services
The heatwave has prompted Network Rail to enforce speed restrictions on two main lines out of London, including the Brighton mainline and the western mainline from Paddington. Track temperatures are anticipated to reach up to 60C (140F), particularly in sun-exposed areas, raising concerns about rail integrity. As a precaution, the state-owned company has painted critical sections of the railway white to reduce heat absorption.
Passenger Advisory and Service Adjustments
Passengers using the Brighton Main Line, Southern, Thameslink, and Gatwick Express services are urged to check the National Rail website for updated schedules. Network Rail spokespersons have advised that fewer trains will operate, and those that do will experience longer journey times. "We're sorry but this means we won't be able to run as many trains as normal," a Network Rail representative stated, suggesting that working from home might be a preferable option for some commuters.
Broader Implications and Safety Measures
The heatwave has not reached the extremes of previous years, but the current conditions highlight the ongoing challenges posed by climate change on the UK's rail infrastructure. Network Rail is responsible for maintaining over 20,000 miles of track, and the current situation underscores the need for adaptive measures to ensure railway safety. The speed restrictions are expected to remain in place until 10pm on Tuesday, affecting thousands of commuters and potentially leading to further cancellations.

Scenario Analysis
Looking ahead, the ongoing heatwave could prompt further scrutiny of the UK's rail infrastructure and its resilience to climate change. Experts suggest that more permanent solutions, such as heat-resistant materials and improved track monitoring systems, may be necessary to prevent future disruptions. Politically, the situation could reignite discussions on infrastructure investment and climate adaptation strategies. As temperatures continue to rise, Network Rail and other stakeholders may need to accelerate efforts to safeguard the rail network against increasingly frequent extreme weather events.
