Over seven meters in diameter
Tunnel machine Elizabeth, named after HM The Queen, broke effectively in to the eastern end of Liverpool Street Crossrail station in the morning 0f 29th of January.
The breakthrough, 40m beneath the City of London, is part of Crossrail’s longest tunnel drive, 8.3km from Limmo Peninsula, near Canning Town, to Farringdon.
Elizabeth now has 750m of tunnel to bore, before arriving at her final destination at Farringdon station. Elizabeth will finish her tunnel drive and link all Crossrail tunnels for the first time with the big east/west breakthrough at Farringdon in the spring.
Her sister machine Victoria will arrive at Farringdon a few weeks later. On completion, a total of 42km of tunnel will have been bored as part of Europe’s largest infrastructure project. 40 km out of 42 km have now been constructed.
Elizabeth and Victoria each weigh 1,000 tonnes, are 150m long and over seven meters in diameter. They are the last of eight Crossrail tunnel machines to have carved a route beneath London linking the West End, the City, Canary Wharf and southeast London.
