Major breakthrough for Crossrail as tunnelling machine enters Canary Wharf station

  • Tunnelling machine Elizabeth breaks through into station box
  • Entire Crossrail project now more than one-third complete

The Crossrail project has celebrated its biggest milestone so far as one of its huge 1,000 tonne tunnelling machines has broken through into the new Canary Wharf station box.

At an event today, Secretary of State for Transport Patrick McLoughlin, Mayor of London Boris Johnson, Crossrail Chief Executive Andrew Wolstenholme and selected guests visited the new Canary Wharf station to view tunnelling machine Elizabeth and the huge progress made on the Crossrail project so far.

Crossrail’s eastern tunnelling machines, named Elizabeth and Victoria, were launched from the Limmo site near Canning Town towards the end of last year to create 8.3km (5.16 miles) of tunnels from east London to Farringdon – Crossrail’s longest tunnel section. A marathon-equivalent 26 mile (42km) section of tunnels beneath central London will be built in total for Crossrail.

Over the past 6 months, both machines have been working round the clock to create the first section of new tunnels beneath the River Lea and east London towards the new Canary Wharf Crossrail station. Tunnelling machine Elizabeth was the first to arrive and has now broken through into the huge Canary Wharf station box 28 metres underground.

Secretary of State for Transport Patrick McLoughlin said: “This Government knows that by investing in transport projects like Crossrail we are investing in Britain. Over the past few years Crossrail has let contracts worth more than £6bn, more than half going to small and medium-sized businesses, which are supporting jobs across the country. Furthermore, through innovative schemes like the Tunnelling and Underground Construction Academy, Crossrail is providing thousands of people with new skills that will not only help transform the capital’s transport network but will allow this country to compete on a global stage for years to come.”

The Mayor of London, Boris Johnson, said: “Many thought it would never happen, it seemed almost unimaginable. But now, with the arrival of this gigantic tunnelling machine in the heart of Canary Wharf, grubby with mud and rubble, we can be in no doubt it’s on its way. This new railway is adding vital new capacity to our transport network and creating thousands of jobs all over the UK. It is the perfect example of how investment in London benefits the entire country.”

Crossrail Chief Executive Andrew Wolstenholme said: “The Canary Wharf tunnelling breakthrough is our biggest milestone so far and a symbolic moment that shows the scale of the essential new transport links Crossrail is delivering. We are making good progress in building world-class new stations and a marathon of tunnels beneath London with the entire Crossrail project now more than a third complete. We are on track to deliver Europe’s biggest construction project on time and on budget.”

The new Canary Wharf Crossrail station box has been designed and built by Canary Wharf Group who are also delivering a four-storey retail development above the ticket hall and platform levels. The retail development will be topped by a roof top garden, community facility and restaurant semi-covered by a striking Foster-designed timber lattice roof.

Canary Wharf Group Chairman and Chief Executive Officer Sir George Iacobescu said: “We are very proud of the role Canary Wharf Group played delivering the Canary Wharf Crossrail station well ahead of schedule, ready for the tunnel boring machines to breakthrough. Four years after construction of Crossrail began here at Canary Wharf, the breakthrough represents a large and tangible step towards a new world-class rail line, set to benefit the whole of London through reduced travel times and much enhanced capacity and resilience.”

Tunnelling machine Elizabeth will now undergo maintenance inside the Canary Wharf station box before resuming tunnelling towards central London. Sister machine Victoria is due to breakthrough into the station in the next few weeks.

Crossrail’s construction commenced on 15 May 2009 with the start of work on Canary Wharf station, with tunnelling work starting in May 2012. The western tunnelling machines Phyllis and Ada have now reached Tottenham Court Road and Bond Street respectively. In south-east London, tunnelling machine Sophia has reached the Woolwich station box with sister machine Mary now underway from Plumstead.

Crossrail is moving into the peak of construction between now and 2015. The entire project is now more than one-third complete and progress made to-date includes:

  • Over 8,000 workers at more than 40 construction sites across London and the southeast
  • Eight tunnel boring machines will be used to construct the Crossrail route with six tunnelling machines now in operation
  • More than 7½ miles / 12 km of tunnels built so far
  • Flagship new Crossrail stations in central London under construction - Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Whitechapel and Canary Wharf
  • Nearly 200 apprentices employed on the Crossrail project and a range of other employment and skills initiatives including the opening of the Tunnelling and Underground Construction Academy
  • Refurbishment well underway at the 135 year old Connaught Tunnel under the Royal Docks which will be brought back into use for Crossrail, including work to open the tunnel from above for the first time since its construction in 1878
  • Work underway to create a new 1,500 acre nature reserve at Wallasea Island in Essex using excavated material from Crossrail’s tunnelling programme

Key milestones coming up on the Crossrail project include:

  • Completion of the first Crossrail tunnels by the end of 2013 - the 6km western section between Royal Oak and Farringdon
  • Crossrail’s final two tunnel boring machines launched later this year to begin further tunnelling work in Pudding Mill Lane, east London
  • Continued progress by Canary Wharf Group on the four-storey retail development above the new Canary Wharf station, including the start of work on the timber lattice roof in late 2013
  • Archaeology work continuing at Crossrail sites later this year including excavation of the Bedlam Burial Ground at Liverpool Street station where up to 4,000 skeletons from the 1600s-1800s are thought to be buried
  • Work nearing completion on the 34.5 metres deep Stepney Green shaft, one of Europe’s largest underground caverns - the two eastern tunnelling machines will pass through the shaftlater this year
  • Throughout the life of the Crossrail project and its supply chain it is estimated that enough work will be generated to support the equivalent of 55,000 full time jobs

When Crossrail opens in 2018, it will increase London's rail-based transport network capacity by 10 per cent and dramatically cut journey times across the city. Crossrail will be fully integrated as part of the TfL network providing a fast, frequent service linking the east and west and relieving congestion on some of the busiest Tube lines.

Notes to Editors:

Joint Venture Dragados Sisk are constructing the eastern tunnels between Limmo Peninsula and Farringdon, Pudding Mill Lane and Stepney Green and Victoria Dock Portal and Limmo.

The total funding envelope available to deliver Crossrail is £14.8bn. The Crossrail route will pass through 37 stations and run 118 km (73 miles) from Maidenhead and Heathrow in the west, through new twin-bore 21 km (13 miles) tunnels below central London to Shenfield and Abbey Wood in the east.

Crossrail is being delivered by Crossrail Limited (CRL). CRL is a wholly owned subsidiary of Transport for London. Crossrail is jointly sponsored by the Department for Transport and Transport for London.
