HS2 in Hillingdon
HS2 in your area
The railway enters Hillingdon in a tunnel from Ealing. It comes to the surface at West Ruislip, then crosses the Colne Valley lakes on a viaduct.
What we're building
Northolt tunnel
The Northolt tunnel runs for 8.4 miles (13.5km) beneath west London, carrying passengers from Old Oak Common to West Ruislip.
Five headhouses will support the Northolt tunnel. One is in Hillingdon. Each headhouse sits above a shaft that ventilates the tunnel and provides emergency access.
South Ruislip headhouse
The South Ruislip headhouse sits between Ruislip Gardens and South Ruislip underground stations, close to Cineworld on Victoria Road in Hillingdon. The Chiltern line railway runs along the southern boundary of the site.
It forms part of the HS2 green corridor – the network of new wildlife habitats, woodlands and community spaces we’re creating along the route – connecting new habitats, trees and shared spaces for people and nature.

Habitat creation sites near Copthall tunnel
We’re creating more than 40 hectares of new wildlife habitat around the Copthall tunnel, between the HS2 tunnel portal near West Ruislip underground station and the western end of Harvil Road. These are dedicated areas for nature, designed to support wildlife along the route for decades to come.
