Direct trains between Scotland and London have been cancelled for Wednesday, after unprecedented temperatures caused damage to rail tracks.
All major routes between London King's Cross and Aberdeen / Edinburgh and London Euston and Glasgow are affected. Passengers are being urged to check National Rail Enquiries before they travel, with people being asked not to travel unless necessary.
Repair work is continuing right across the country’s rail network after the extreme heat. People are advised that journeys will take longer, and trains could be busier while services return to normal after the unprecedented temperatures put a huge strain on the railway.
