Over 80 miles of tunnel will be built to carry HS2 trains
We're currently constructing new tunnels between London and the West Midlands, forming part of the HS2 network that will help connect the country, create thousands of jobs and rebalance the UK economy.
How we’re building our tunnels
HS2’s tunnels will be built using different construction techniques to suit their purpose and local conditions. We’re building them under cities and the countryside to help reduce the impact on people and nature.Find out more about how HS2 will build tunnels

Tunnel boring machines
Ten giant tunnel boring machines (TBMs) will dig the 64 miles of tunnels between London and the West Midlands. Each machine operates as a self-contained underground factory – digging the tunnel, lining it with concrete wall segments and grouting them into place at a speed of around 15 meters a day.Find out more about our giant tunnel boring machines

We’re currently constructing the tunnels that will serve the London to West Midlands section of the railway. These will be constructed in a number of different locations along the route. In total 130 million tonnes of earth will be excavated, enough to fill Wembley Stadium 15 times.
