Network Rail said a large section of the railway south of Peterborough will be closed between Saturday and Sunday. This was due to in-cab digital signalling being installed as part of a 1.4bn East Coast Digital Programme (ECDP), which aimed to create greener, safer and more reliable journeys for passengers. As a result, London North Eastern Railway (LNER) will have rail replacement coaches between Peterborough and Bedford, where customers can join train services to London St Pancras.
No trains will run in or out of King's Cross station across one weekend, with widespread service cancellations and diversions affecting multiple operators including LNER, Great Northern, Thameslink, and Grand Central. The works form part of a long-term infrastructure upgrade designed to improve reliability and capacity on one of the UK's busiest rail routesbut in the short term, they will cause significant travel disruption across London and the southeast.
