Rail passengers are being warned of major disruption between Edinburgh and Dunbar until the end of service today.

National Rail has described how the overhead electric wires between both stations - at Wallyford - have been severely damaged.

The network added: “One line has been reopened to allow trains to run at a reduced speed, but delays and alterations can be expected.

“Limited road transport is running between Edinburgh and Berwick-upon-Tweed in both directions.

“Please allow for an extended journey time when travelling between these stations.”

The routes affected are CrossCountry between Edinburgh and Plymouth and ScotRail between Edinburgh / Ayr and Dunbar / North Berwick.
