Fourth Crossrail TBM launched

Construction of tunnels for Crossrail are now being progressed on four fronts following the launch of another of the scheme’s tunnel boring machines (TBM) today.

The 1,000t earth pressure balance Herrenknecht TBM – named Victoria – has started tunnelling work at Limmo and will construct one of two 8.3km bores between there and Farringdon.

“The start of tunnelling by Victoria is a significant milestone on which to end 2012,” said Crossrail chief executive Andrew Wolstenholme. “With sister machine Elizabeth already underway, tunnelling for Crossrail’s eastern tunnels between Docklands and Farringdon is now fully up and running.”

Elizabeth and Victoria are schedule to complete their journey westwards and arrive in Farringdon in 2014. The launch of the TBMs on the eastern running tunnels follows on from the launch of two other machines – Phyllis and Ada – from Paddington earlier this year.
