Network Rail will close the East Coast Main Line for all locations between London King’s Cross and York and Leeds due to the extreme weather expected on Tuesday 19 July. Passengers are being warned not to travel.

The closure will be in place from 12noon until 8pm with a skeleton service running in the morning. 

The closure comes amid forecasts of record temperatures and the declaration of a national emergency. The current forecast maximum air temperature on Tuesday 19 July is 39 to 40 degrees through the full 173 miles of the Kings Cross to York section of the East Coast Main Line.

The national rail body says that a combination of extremely high local forecast temperatures and temperatures well in excess of those for which the infrastructure is designed for on the East Coast corridor has led to this decision.

This means many train companies will not run any services and others will be very limited. Passengers are being asked to replan their journey for another day where possible or get a refund.

Conditions on other routes will be closely monitored with further changes to service possible. Network Rail says that additional response staff will be out on the network to respond to incidents, but the heat makes working conditions challenging for them too.

Sam MacDougall, operations director for Network Rail said: “Closing the line to traffic is always a last resort but it is the right thing to do to keep people safe on Tuesday given the unprecedented heatwave forecast. The forecast temperatures are well above those which our infrastructure is designed, and safety must come first.

“On Monday we are reducing the speed at which trains can run which will limit the number of trains running and extend journey times significantly so we’re asking passengers to only travel if absolutely necessary. 

“The best way to keep everyone safe and prevent passengers from becoming stranded on trains in the extraordinary heat is to proactively close the East Coast Main Line routes south of York and Leeds during the very hottest temperatures. I am sorry for the disruption this will cause.”

Jason Webb, director of customer information, Rail Delivery Group, said: “These are extreme temperatures and while the whole industry is pulling together to deliver the best possible service under the circumstances, we must ask people to only travel if absolutely necessary.”

Network Rail has also issued the following train service information for Tuesday:
