Crossrail is one of Europe’s largest transport infrastructure projects

Crossrail’s Western Tunnels Contract is one of the largest of the Crossrail contracts. At peak production the TBMs can each advance up to 40 metres in a day excavating in excess of 3,000 tonnes and installing 575 tonnes of concrete tunnel lining rings.

The western tunnels (C300/410) work comprises two 6.2m internal diameter bored tunnels, each 6.5km long between the Royal Oak portal, which is west of Paddington Station, and Farringdon Station, and the sprayed concrete lining (SCL) station tunnels at Bond Street (BOS) and Tottenham Court Road (TCR) and the Fisher Street (FS) cross over tunnel, including ticket hall shaft construction at TCR. The western tunnel drive, between Royal Oak and Farringdon is one of five drives and will be the point at which the existing Network Rail services on the western section of the route enter the tunnels under central London.
