PA MediaLiverpool Street Station will be closed for eight days between Christmas Day and New Year’s Day for works to be carried out on its roof, Network Rail said.
It has urged people travelling over the Christmas period to check journey plans if travelling via the UK’s busiest station.
Strengthening work will also be carried out inside the Bishopsgate Tunnel approach to London Liverpool Street, alongside signalling renewal work across Cambridgeshire.
Full services will resume from and to the station on 2 January, it added.
EPAThe engineering work taking place in Cambridgeshire will start on Christmas Day and last up to 11 days, Network Rail said, to deliver the second stage of the Cambridge re-signalling project and modernise the system.
Signalling engineers will introduce a new control system to operate the signals for the section of railway between Cambridge North and Audley End.
“A new digital workstation at the Cambridge signalling centre will replace the 40-year-old signalling panel allowing signallers to oversee the operation of the network more efficiently,” Network Rail said.
“This work is also vital to allow the new station at Cambridge South to open early in the New Year.”
An upgrade to the Meldreth Road level crossing in Cambridgeshire will see a full barrier CCTV system introduced too.
From 27 December to 4 January 2026, there will be no rail services between Royston and Stansted Mountfitchet and Cambridge and Cambridge North.
