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. 

Latest information on HS2 in Brent and Ealing

Update following Government announcement on HS2

The Government updated Parliament on their transport capital investment programme on 9 March 2023. A copy of the Transport Secretary’s statement is available online here. The statement included an update on the HS2 project, recognising significant inflationary pressures facing all parts of the UK economy.

In line with direction from the Government following its announcement in March 2023, work at the Canterbury Works site will be brought to a safe stop, and paused from Autumn 2024. Until this time activities will continue as planned at the site. These dates could be subject to change, and we will keep the community updated about any changes. During the pause in works, the site hoarding and 24-hour security will remain in place.

We will continue to maintain the site and carry out any required traffic management and environmental monitoring. Some works will continue, within and outside the site, including monitoring, surveys, and design work.

Please see this community notification with further information about what construction activities will continue until the pause in works.
