The western tunnel drive, between Royal Oak and
Farringdon, will be the first of 5 drives required to construct the
Crossrail tunnelled section. It will be the point at which the existing
Network Rail services on the western section of the route enter the
tunnels under central London.
The first two tunnel boring machines, Phyllis and Ada,
began tunnelling from Royal Oak towards Farringdon in 2012. Their
tunnel drives are approximately 6.4 km long - the second longest on
drives on the Crossrail project.
The tunnelling machines from Royal Oak Portal passed
successfully underneath the Network Rail tracks west of Paddington
Station en route to the Crossrail station sites at Paddington, Bond
Street, Tottenham Court Road, and on to Farringdon east. Once each
machine arrives at Farringdon the cutter heads will be removed from the
ground using giant cranes and the machines dismantled.
In order to deliver the new rail tunnels our western
tunnels contractors are managing a number of worksites from Old Oak
Common through to Farringdon.
Construction of Royal Oak Portal,
the first of five new tunnel portals to be constructed for Crossrail,
commenced in January 2010 and was completed ahead of schedule in
September 2011. The portal structure will be used for the
construction of the new twin-bore tunnels, and in the future will
provide the western entrance and exit for trains to the underground
sections of Crossrail.
