King's Cross closed on 28–29 November for digital signalling work

No trains will run between London and Peterborough or Letchworth Garden City on Saturday 28 and Sunday 29 November, as Network Rail closes the southern end of the East Coast Main Line to update the systems behind its new in-cab digital signalling. King's Cross, Moorgate and the Great Northern and Thameslink routes north of London are affected all weekend.

Network Rail announced the closure on 2 November. Teams will update the diagnostic systems, data and software used by the digital in-cab signalling that some East Coast Main Line trains already use, to make it more reliable before more services switch to it during 2027. The work is part of the £1.4bn East Coast Digital Programme, which replaces lineside signals with information sent directly to the driver's cab. Digitally signalled passenger trains began running between Welwyn Garden City and Hitchin in August.

The weekend will also be used for track renewal at New Southgate and near Potters Bar, step-free access work at Alexandra Palace, canopy repairs at Bowes Park and overhead line maintenance at several locations.

How each operator will run

LNER trains will start and finish at Peterborough, with accessible replacement coaches to Bedford, where Thameslink trains continue to London St Pancras. On Saturday, LNER will run two Newcastle–Bedford trains each way, leaving Newcastle at 08:27 and 10:27. Hull Trains will divert a reduced service to St Pancras, with two trains each way on Saturday and three on Sunday, missing out Beverley, Cottingham, Doncaster, Retford and Grantham. Grand Central will not run at all, and its 07:48 King's Cross to Sunderland on Monday 30 November is also cancelled. Lumo will only run between Newcastle and Edinburgh or Glasgow Queen Street.

Great Northern and Thameslink will run a shuttle between Letchworth and Cambridge, Ely and King's Lynn. Replacement buses will link Alexandra Palace with Stevenage and Welwyn Garden City, Stevenage with St Albans City and Luton Airport Parkway, Hitchin with Letchworth and Peterborough, Cockfosters with Potters Bar, and Bedford with Peterborough via St Neots and Huntingdon.

Tickets and alternatives

Tickets will be accepted on Thameslink between St Pancras and Bedford, on Greater Anglia between Liverpool Street and Hertford East or Cambridge North, and, for paper tickets, on London Overground between Liverpool Street and Enfield Town and on sections of the Piccadilly, Victoria, Northern and Central lines. LNER warns that routes via Sheffield, Derby, Nottingham and Cambridge are expected to be very busy. Network Rail's advice is simple: if you can, travel on the days before or after.

The closure lands in a busy month for planned works on Britain's main lines. London Euston faces its own reduced service over Christmas, covered in our Euston closures guide, and the line between Derby and Matlock is shut until 22 November, as explained in our Derwent Valley Line article.
