🚄🔧 Passengers are warned of rail disruptions south of Peterborough on Sunday 15 March due to further testing of a new digital signalling system. Thameslink and Great Northern services will not run on key sections, with replacement #buses operating between Hitchin, Bedford, Peterborough, St Neots, Stevenage, Hertford North, Potters Bar and #Luton #Airport Parkway. Long-distance trains from northern #England will start or terminate at #Peterborough, with coaches connecting to Bedford and #London. The £1.4bn East Coast Digital Programme is introducing in-cab digital signalling between Welwyn and Hitchin later this year, aiming for safer, greener, and more reliable journeys. Passengers are advised to check National Rail before travelling and allow extra time. https://www.mynewsdesk.com/uk/govia-thameslink-railway/pressreleases/video-passengers-reminded-of-rail-service-changes-south-of-peterborough-on-sunday-15-march-3435932
