Enabling work at weekends in early January and mid-February will mean diverted services on the East Coast Main Line. The work will hasten the introduction of digital signalling ETCS to the route famous for the Flying Scotsman and the principal connection between London and Edinburgh. Passengers intending to travel to and from London and other destinations via Peterborough, and across Great Northern commuter routes over the weekend of 7 and 8 January are being asked to plan ahead.
