Euston Tunnel
Euston Tunnel will carry high-speed trains between London Euston Station and Old Oak Common Station. The 4.5-mile (7.2km) twin-bore tunnel will reach depths of up to 50m below ground. It will be excavated using two tunnel boring machines (TBMs), Karen and Madeleine, which will be launched from the eastern section of HS2’s Old Oak Common Station.
Tunnel construction
Engineers have begun assembling two giant tunnelling machines that will dig the final 4.5 miles of underground high-speed railway that will carry HS2 trains into the heart of the capital.
Weighing an incredible 1,250 tonnes, each of the tunnel boring machines (TBMs) will launch from an underground box at one end of the project’s Old Oak Common station. They are expected to take around one and a half years to complete their drives.
The two 190m long TBMs were manufactured by world-leading tunnelling experts Herrenknecht AG in Germany and were transported to Old Oak Common in pieces before being reassembled on site. The HS2 team lifted the machine in pieces using a 750 tonne crane into the Old Oak Common underground box, where they are being reassembled, ready to bore to HS2’s terminus station in the capital.
The cutterheads of each machine, which have been optimised to cut through London clay, is 8.53m across with the inner diameter of the tunnel set to be 7.55m.
The Atlas Road Logistics Tunnel, which will be used to deliver materials and remove spoil for the Euston Tunnel, has been completed.
