HS2 in Hillingdon

HS2 in Hillingdon
Proposed Colne Valley Viaduct crossing Harefield lake

Find out what HS2 means for Hillingdon

In Hillingdon, the HS2 route will surface from the new Northolt Tunnel (that connects Old Oak Common to West Ruislip), at the West Ruislip Portal, which sits alongside the existing Chiltern railway line.

The route will then cross over a new bridge close to the existing Chiltern Line railway bridge, and towards the Colne Valley Viaduct.

Two tunneling machines will be launched from the West Ruislip Portal and will travel five miles east underground to create the western section of the Northolt Tunnel.
