The work happening between North Berwick and Dunbar will help to keep trains running smoothly for years to come on the line, which links Edinburgh Waverley to London King’s Cross.

To allow engineers to carry out improvements safely and efficiently, the line between Edinburgh and Newcastle will be closed from Saturday 19 September to Monday 21 September and from Saturday 26 September to Monday 28 September.

During the works, a kilometre of track will be renewed at Hedderwick and new drainage systems installed with a further half a kilometre of rails being replaced at Ninewar.

A project to stabilise a slope on the railway at Howburn, near Reston, will also be delivered during the closures.

On the following weekend, Saturday 3 October and Sunday 4 October, engineering work will also be taking place south of the border between Newcastle and Berwick.

Ross Moran, route director at Network Rail Scotland, said: “This is an important investment in the East Coast Main Line, helping us deliver a more reliable railway for passengers and freight customers travelling on essential cross-border services.

“By closing the line over weekends, our engineers can carry out a significant amount of work safely and efficiently, reducing the need for future maintenance and keeping the railway running smoothly for years to come.”
