Crossrail has delayed its opening again with project chiefs blaming the latest setback on Covid-19.
The troubled railway, from Reading, Berkshire to Abbey Wood, Essex via central London, was originally expected to open in December 2018 but repeated delays have pushed it back.
Crossrail confirmed on Thursday that this is now “not achievable.”
On Thursday evening, Crossrail said: “A programme of this scale and complexity was already challenging, the impact of Covid-19 has clearly made the existing pressures more acute.
“Due to a pause of physical activity on sites and significant constraints on ongoing work – time has been lost, only some of which can be recovered.”
Construction work stopped due to Covid-19 on March 24 and restarted on June 15. Train testing work restarted earlier on May 30.
The rail line was due to open in December 2018 but has been beset by a number of delays and increases to its original £14.8bn budget, which was agreed in 2010.
Crossrail chiefs have not issued a revised timetable but said “a more comprehensive update will be issued in due course.”
They added: “Work continues to refine and validate the remaining work schedule and associated costs.”
Mark Wild, Chief Executive, Crossrail Ltd, said: “We have a comprehensive plan to complete the railway but existing schedule pressure along with Covid-19 has impacted the programme and time has been lost.
“Despite the challenges presented by Covid-19, good progress continues to be made with completing the remaining construction works, with much of this work coming to an end along with software testing for the signalling and train systems.
“The focus is completing the outstanding works across the tunnels, shafts and portals so that intensive operational testing can begin and the Elizabeth line can be delivered at the earliest opportunity.”
Andy Byford, London’s new transport commissioner, said: “The news that coronavirus and other factors mean the railway cannot now open next summer is hugely disappointing.”
Last month was announced that Crossrail and the Costain Skanska joint venture building the project’s problem Bond Street project have parted ways. Crossrail will oversee completion of the remaining works in-house.
