on Sunday 30 August, Great Northern and Thameslink services on the East Coast Main Line will be affected by engineering work in connection with the ongoing East Coast Digital Programme.
Additionally, evening services from approximately 20:00 onwards on Saturday 29th August and early morning services until approximately 09:00 on Monday 31st August (which is a Public Holiday), will also be affected.
The work taking place โ which involves final testing to allow the industry to begin a gradual introduction of digital in-cab signalling on the main line โ means that during the closure from the Saturday evening until the Monday morning, no trains will run between Potters Bar and Peterborough or Royston, and between Hertford North and Stevenage.
Train services will run between Kingโs Cross or Moorgate and Potters Bar or Hertford North and between Royston and Cambridge / Kingโs Lynn.
Replacement buses will run in closed sections, with some of the bus routes designed to link up with alternative rail routes on the Midland Main Line for train connections to and from central London.
Journey planners on our websites and at www.nationalrail.co.uk are fully up-to-date, including the exact last train times on the evening of Saturday 29 August, alongside a summary to the dedicated East Coast Digital Programme webpage. An overview of the customer impact and replacement bus services is available below.
The attached map provides an overview of the impact to train services on Sunday 30th August date and shows the routes replacement buses will serve on that day.
