Network Rail has issued an urgent warning for rail passengers across the UK to avoid travel on Wednesday and Thursday, as a rare red alert for extreme heat has been declared for several regions. Transport for London (TfL) has also cautioned that the Elizabeth Line and Overground services are likely to face the worst disruption, with speed restrictions and reduced services expected due to scorching rail temperatures.
Red Warning Zones and Travel Advice
The Met Office red warning covers parts of the West Midlands, East Midlands, South East, South West, London, and East of England. Jake Kelly, deputy chief executive of Network Rail, stated: "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."
Passengers who must travel are advised to plan ahead, allow extra time, and carry water to stay safe. Those with tickets for Tuesday, Wednesday, or Thursday can use them on Friday, Saturday, or Sunday instead, or claim refunds if they choose not to travel.
TfL and Operator Warnings
Claire Mann, TfL's chief operating officer, warned: "Customers should be aware that, given the very high temperatures that are forecast, we are likely to see some disruption to rail and Tube services - with rail temperatures likely to lead to temporary speed restrictions and therefore reduced services in some cases. This will vary by line, with some services that share parts of the overground rail network - like the Overground and the Elizabeth line - likely to be more affected." She added that bus services are expected to run normally, but passengers are encouraged to carry water.
Chiltern Railways, which operates between Birmingham and London Marylebone, has alerted passengers to anticipate "significant disruption," with severely curtailed services, substantial delays, and extremely crowded conditions.
Health Impact and UKHSA Alert
The UK Health Security Agency (UKHSA) has issued a red health warning for the same five regions, effective from 1am Wednesday to 11pm Thursday. The extreme heat poses a threat to health and potentially lives, especially for vulnerable individuals. The Met Office red warning is the highest level, indicating dangerous weather conditions are imminent, with major travel disruption expected across the rail network.
