High Speed 2 (HS2) is a high-speed railway which has been under construction in England since 2019. The line's planned route is between Handsacre, in southern Staffordshire, and London, with a spur to Birmingham. HS2 is to be Britain's second purpose-built high-speed railway after High Speed 1, which connects London to the Channel Tunnel.
The Northolt Tunnel is a high-speed railway tunnel currently under construction in Greater London, England, and will upon completion carry the High Speed 2 (HS2) railway line under the West London suburbs. The twin-bore tunnels will run for 8.4 miles (13.5 km) between Old Oak Common and Ruislip.
The twin-bore tunnels, which are 16.04 km (9.97 miles) long, [1] will be the longest on the HS2 line. [2] Each tunnel will also have additional 220 m (720 ft) entry and 135 m (443 ft) exit perforated concrete portals to reduce sudden changes in air pressure and subsequent noise. [3]
