Rail passengers travelling to, from, or within extreme heat zones urged to only travel if absolutely necessary during record heatwave – Network Rail media centre

Monday 22 Jun 2026
Passengers are being urged to only take essential train journeys to, from or within areas affected by extreme heat – as record June temperatures hit.
The Met Office has issued the rare red weather warning for large parts of southern England and Wales, during Wednesday 24 June and Thursday 25 June, with forecasters warning that June’s all-time daily temperature record could be broken.
All passengers should check before they travel on Tuesday 23 June, as temperatures begin to soar.
Then on Wednesday 24 June and Thursday 25 June, as the most extreme conditions are expected, passengers travelling to, from or within the red zones should only travel is absolutely necessary – while passengers outside those areas should continue to check travel plans carefully.
Rail services will continue to run, but passengers should expect disruption across the network. For safety reasons, trains will operate at reduced speeds and to amended timetables, meaning journeys will take longer and there is a heightened risk of delays, cancellations and last-minute alterations. There will be no rail replacement bus services during this period.
Passengers who do need to travel are strongly advised to prepare for the conditions by bringing plenty of water, wearing sunscreen and a hat, and ensuring that they have a back-up plan in case of disruption.
This guidance is directly linked to the geographical area covered by the Met Office’s red and amber weather warnings, across England and Wales, and we are monitoring this closely. If it changes, we may modify our guidance.
Jake Kelly, deputy CEO of Network Rail, said:
“Extreme heat can have a significant impact on the railway, so safety must come first. We’re asking passengers to check before travelling on Tuesday, and only travel if absolutely essential on Wednesday and Thursday if they are going to, from or within the red warning zone as temperatures are expected to peak.
“If you do need to travel in this area or outside of it where it will still be hot, please plan ahead, allow extra time and take necessary precautions, such as carrying water, to stay safe. We thank passengers for their patience and understanding during this period.”
Customers holding tickets for travel on Tuesday 23 June, Wednesday 24 June, or Thursday 25 June, are advised that they may be able to use their tickets on alternative dates or times. Customers are encouraged to check on the National Rail Enquiries website or their rail operator’s website for the latest travel information and details of ticket acceptance
Extreme heat can affect track, ground conditions, power and signalling systems, increasing the likelihood of disruption across the network. The rail industry is using a combination of proactive monitoring and investment in smart technologies — including remote sensors and innovative cooling solution – to protect critical infrastructure, strengthen the resilience of Britain’s railway network  and keeping passengers moving safely during extreme weather.
Passengers are reminded to take the following steps to stay safe when travelling in hot weather:
