I’ve been informed that late on Fri 21st and all day Sat 22nd September that the line between Berwick and Edinburgh is closed for maintenance, meaning some changes to the schedule.
LNER trains between London and Edinburgh will run as normal, however they’ll take a diversion after Newcastle that will add 90mins to the journey time. Replacement buses calling at the intermediate stops (Morpeth, Alnmouth, Berwick, Dunbar) are also running between Newcastle and Edinburgh.
With CrossCountry trains, a replacement bus is running between Berwick and Edinburgh during this time.
