Track temperatures could hit 50°C, prompting Network Rail to enforce speed restrictions along sections of the Brighton Main Line. These measures help prevent damage and ensure passenger safety.

Southern, Thameslink, and Gatwick Express are urging travelers to check schedules before departure. Revised timetables are now live on operator websites and on nationalrail.co.uk.

Because high temperatures affect the stability of steel rails, operators are running fewer trains at slower speeds. This results in longer journey times and more crowded services.

A spokesperson from Network Rail said the heatwave makes it necessary to slow trains across key parts of the network. Safety remains the top priority under such extreme weather conditions.

He added that passengers should work from home if possible. Those who must travel should stay hydrated and report any illness to station staff immediately.

To keep trains operating safely, all services are now running under adjusted schedules. Each company updated its platforms to reflect changes caused by the intense heatwave conditions.

Travelers are also reminded to bring water on board and avoid using emergency alarms unless absolutely necessary. Misuse may delay assistance and disrupt operations further.

Rail Industry Responds to Growing Climate Challenges

As climate extremes become more frequent, rail operators must adapt. This week’s disruptions reflect the urgent need for resilience planning amid rising environmental risks.

Speed limits and reduced services will remain in effect through Tuesday. Passengers should continue checking updates as conditions evolve.
