Weekend work will take place during February and March as part of the East Coast Digital Programme.
This will include the installation and testing of new signalling equipment on the Northern City Line.
In the future the new equipment will enable signallers to communicate with train cabs in real time. This will boost reliability and worker safety as well as reduce delays.
On 12-13 February and 12,13 and 20 March no trains will run between Finsbury Park and Moorgate. Trains to and from Moorgate will be diverted into London King’s Cross.
Work is also scheduled to take place to upgrade tracks and install new signalling equipment on the route between Hatfield and Knebworth on the East Coast Main Line.
A revised timetable will be in service on trains between London and Cambridge/King’s Lynn/Peterborough during 20 and 27 February and 6,13, 20 and 27 March.
These services will be diverted via Hertford North, plus replacement buses will run between Alexandra Palace and Stevenage via Welwyn Garden City and between Hertford North and Stevenage.
“The work we’re carrying out over the next few months is crucial to enable us to introduce digital signalling, helping to improve journeys for passengers.
“The nature of the work means there will be service changes and we are sorry for any impact which this has. We’d encourage all those travelling on these routes through February and March to check their journey ahead of time.”
