HS2 in Brent and Ealing
The new high-speed railway through Brent and Ealing runs entirely underground via the Northolt Tunnel, linking Old Oak Common to West Ruislip.
Four tunnel ventilation shafts at Canterbury Road, Westgate, Green Park Way, and Mandeville Road will regulate air flow and provide emergency access. Headhouses above each shaft will house ventilation and fire control systems.

Update following Government announcement on HS2
In autumn 2024, the government confirmed that HS2 will be built to Euston, and we are now preparing for construction of the tunnel from Old Oak Common. Construction on associated works, including the tunnel shafts, headhouses and station approaches, will start at a later date. We are currently reviewing the whole HS2 programme as part of a major reset – making sure the building blocks of the scheme are in the correct sequence. We will keep you updated when the works at the Canterbury Works Headhouse will restart.
Information for Ealing
Most of the route through London will be in tunnel, including about five kilometres of tunnel in Ealing between Victoria Road in North Acton and the boundary with Hillingdon.
