Delicate work: the middle shield of TBM Anne is lowered into the ground (Image: HS2)
THE HS2 rail project has completed the lifting of Tunnel Boring Machine (TBM) components at its Victoria Road Crossover Box site in Ealing.
The final lift, of the middle shield of the TBM named Anne, was completed on Friday evening (17), under the lights of the Wembley stadium arch.
Striking photos show the 336-ton component being lifted by a 750-ton crane into the caterpillar shaped crossover box.
TBMs will be used to dig the eastern half of the Northolt Tunnel, which will ultimately be used to take the new high-speed line between Old Oak Common station and outer London.
They will complete a 3.4-mile stretch of the tunnel from Victoria Road to Greenford, beginning their journeys in the new year.
