A team of 90 specialist engineers have completed the assembly of HS2’s giant tunnel boring machine (TBM) which will start digging the second bore of the 3.5 mile Bromford Tunnel into Birmingham in the new year.

In one of the most impressive assembly operations to move sections of the machine into a 12 metre deep launch pit, two 600 tonne cranes lifted the huge new cutterhead into place at the front of the 125 metre long machine in the pit bottom.

The first TBM, named ‘Mary Ann’ after Mary Ann Evans – the real name of Victorian writer George Eliot who was born in Nuneaton – started digging the first bore from the east portal site near Water Orton in August this year. It has already built more than 500 tunnel rings, which is 0.6 miles of the 3.5 mile long tunnel between North Warwickshire and Washwood Heath in Birmingham.

The name of the second TBM will be revealed before it launches in Spring next year. ‘Mary Ann’ is set to break through at the end of 2024, with the second TBM planned to complete its journey in the middle of 2025.
