Crossrail has released a new series of images to mark the breakthrough of the second tunnel boring machine (TBM) into Liverpool Street station.
Arrival of the TBM – named Victoria – marks the completion of 40km out of the 42km of bored tunnels on Crossrail.
The first TBM to break through at Liverpool Street station – Elizabeth – arrived in January and is currently being prepared for re-launch to complete the final 750m of the 8.3km drive to Farringdon.
Victoria was launched by the Dragados Sisk joint venture from the Limmo Peninsula in 2012. The TBM will be re-launched after passing through the Liverpool Street station box, which has been built by a joint venture comprising Balfour Beatty, BeMo Tunnelling, Morgan Sindall and Vinci Construction.
