High Speed 2 (HS2) is a high-speed railway which is under construction in England. The line will run 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. London and Birmingham will be served directly by new high speed track, and services to Glasgow, Liverpool and Manchester will use a mix of new high speed track and the existing West Coast Main Line. The majority of the project is planned to be completed by 2033.

The new track will be built between London Euston and Handsacre, near Lichfield in southern Staffordshire, where a junction connects to the north-south West Coast Main Line. There will be new stations at Old Oak Common in northwest London; Birmingham Interchange, near Solihull; and Birmingham city centre. The trains will reach a maximum speed of 360 km/h (225 mph) when operating on HS2 track, dropping to 201 km/h (125 mph) on conventional track.

The length of the new line has been reduced substantially since it was first announced in 2013. It was originally to split into eastern and western branches north of Birmingham Interchange; the eastern branch would have connected to the Midland Main Line and East Coast Main Line, with a branch to a terminus in Leeds, and the western branch would have had connections to the West Coast Main Line at Crewe and south of Wigan, and a branch to a terminus in Manchester. Between November 2021 and October 2023 the project was progressively cut until only the London to Handsacre and Birmingham section remained.

The project has both supporters and opponents. Supporters of HS2 believe that the additional capacity provided will accommodate passenger numbers rising to pre-COVID-19 levels while driving a further modal shift to rail. Opponents believe that the project is neither environmentally nor financially sustainable.
