Euston tunnel
The 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 50 metres below ground. It will be excavated using two tunnel boring machines (TBMs), Karen and Madeleine, which will be launched from the eastern section of Old Oak Common station.
Euston tunnel settlement
Settlement is the technical term for the way ground moves around a hole after it’s been dug out.
A settlement deed is a formal legal agreement between you and us. It records the protection your property already has under the High Speed Rail (London – West Midlands) Act 2017.
Westgate gas diversion
We’re installing a high-voltage connection to power the Westgate ventilation shaft and headhouse site.
The works will take place on the footpath and embankment on West Gate, near Hanger Lane Gyratory.
Information for Ealing residents
Most of the route through London will be in tunnel. This includes about 3 miles (5km) of tunnel in Ealing between Victoria Road in North Acton and the boundary with Hillingdon.
Here’s some information about support available for you.
Victoria Road Crossover Box
We’ve proposed designs for the Victoria Road Crossover Box headhouse and plant room.
In July 2025, we produced design proposals for the auto-transformer station, boundary wall, access road and security lighting. We shared them with members of the public ahead of planning submission to the local planning authority. We also provided designs in September 2024.
Northolt tunnel
The Northolt Tunnel will carry passengers between Old Oak Common Station and West Ruislip, where the high-speed railway emerges from underground. Spanning 8.4 miles (13.5km), the twin-bore tunnel will be used by trains travelling from Birmingham to London (upline), and from London to Birmingham (downline).
Mandeville Road headhouse
The Mandeville Road Headhouse in Ealing is one of four shafts along the Northolt Tunnel route of HS2. It is located on the old Affinity Water pumping station off Mandeville Road, Northolt. This is a residential area with Northolt Station to the west and the Network Rail corridor to the south.
Currently, works are ongoing to build the ventilation shaft and satellite shaft with works to build the headhouse building planned from early 2025.
