- High Speed 2, kurz HS2, ist der Projektname einer geplanten und teilweise im Bau befindlichen britischen Eisenbahnschnellfahrstrecke. Der erste Projektabschnitt umfasst die Strecke vom Londoner Bahnhof Euston nach Birmingham (Phase 1). Daran schließen sich zwei Streckenäste an, die in Richtung Manchester bzw. Leeds führen (Projektphasen 2A und 2B). Es wird die zweite Schnellfahrstrecke in Großbritannien, nach der 2003 (teilweise) bzw. 2007 (vollständig) eröffneten High Speed 1. 2020 wurde mit dem Bau der ersten Teilabschnitte begonnen. (de)
- High Speed 2 (HS2) is a planned high-speed railway line in the United Kingdom, with its first phase under construction in stages and being due for completion between 2029 and 2033, depending on approval for later stages. The new line will run from its most southerly terminus, London, to its most northerly point, Manchester, with branches to Birmingham and the East Midlands. HS2 will be the country's second purpose-built high-speed line, the first being High Speed 1, which connects London to the Channel Tunnel. At its southern end, the line terminates at London's Euston station while other termini are Birmingham Curzon Street station and Manchester Piccadilly station. In addition to these stations, the dedicated track will serve Old Oak Common in west London, Birmingham Interchange, East Midlands Parkway south of Nottingham, Crewe, and Manchester Airport. There will be several junctions for trains to progress onto the existing West Coast Main Line and Midland Main Line to reach towns and cities in Scotland, North West and North East England, and the West and East Midlands, which are not served by the new high speed track. The trains, are capable of operating at the line's design speed of 400 km/h (250 mph), will operate at a maximum speed of 360 km/h (225 mph). The trains will operate on both HS2 track and existing conventional track, being able to reach locations off the HS2 line using a mixture of HS2 and conventional network services. Future orders could include "captive" trains, to be used solely on the high speed spine. The project is to be accomplished in three phases. Phase 1, which is under construction, is from London to a junction with the West Coast Main Line near Lichfield with a branch to Birmingham. Construction on the line began in 2020 with tunnelling beginning under the Chiltern hills on the edge of northwest London in 2021. Phase 2a, from Lichfield to a second junction with the West Coast Main Line at Crewe, has achieved royal assent but full construction has not yet commenced. Phase 2b is from Crewe to Manchester, with a link to the West Coast Main Line at Crewe for trains to continue to Scotland, and from the West Midlands to East Midlands Parkway where HS2 joins the conventional rail Midland Main Line. Phase 2b is awaiting parliamentary approval. The original design for HS2 was a "Y" network, with two legs forking at Birmingham. The fork to the west was to proceed to the North West of England at Golborne south of Wigan, where it would connect onto the West Coast Main Line to Scotland, with a branch to Manchester. The fork to the east was to proceed to the northeast of England, at York, where it would connect to the East Coast Main Line to Newcastle, with a branch to Leeds. There was to be a link in London across Camden, linking HS2 and HS1 and giving access to the continent from all major cities. There was also to be a link from Uxbridge to Heathrow. The proposed network has been cut substantially since it was announced in 2013. Links to HS1 and Heathrow were dropped at an early stage. From November 2021 to June 2022, substantial parts of HS2 were dropped. As part of the Integrated Rail Plan for the North and Midlands, it was announced that most of the eastern leg of phase 2b from Birmingham via the East Midlands to Leeds/York would be dropped. The branch from Coleshill near Birmingham towards Nottingham remains, with the route diverted to the existing East Midlands Parkway station, where trains can continue north onto the conventional rail Midland Main Line. The link from Golborne onto the West Coast Main Line was dropped. The project has both supporters and opponents. Supporters of the project believe that the additional capacity and reliability provided by HS2 will accommodate passenger numbers rising to pre-COVID levels while driving a further modal shift to rail. Opponents believe that the project is neither environmentally nor financially sustainable. In 2019, in response to criticism, the government ordered a review of the project—chaired by the project's former chairman, Douglas Oakervee—which recommended that the entire project proceed as planned. However, the Integrated Rail Plan for the North and Midlands, released in November 2021, cut back the project, as well as the Northern Powerhouse Rail project it is integrated with. In 2010, the construction costs of HS2 were estimated to be between £30.9 billion and £36 billion; in 2015, this estimate was combined with the cost of rolling stock, and adjusted for inflation, to result in a budget of £56.6 billion. Oakervee's 2019 review estimated the project would cost up to £87 billion at 2019 prices for the originally envisioned "Y" network. (en)
- High Speed 2 (HS2) est un projet de ligne à grande vitesse entre Londres et les Midlands, le nord de l'Angleterre et peut-être plus tard la ceinture centrale de l'Écosse. Le projet est en cours d'étude par High Speed Two Ltd., une société créée par le gouvernement britannique. La ligne se composerait d'un tronçon entre Londres et Birmingham, sans arrêt intermédiaire, à partir duquel la ligne bifurquera ensuite vers Manchester et Leeds, par la ligne des East Midlands. En principe, le projet de train à grande vitesse est soutenu par les deux grands partis politiques du Royaume-Uni — le UKIP et le Parti vert sont opposés à ce projet qui ne leur semble pas justifié —, cependant les questions des villes desservies et de l'impact environnemental restent une source de désaccord. Le gouvernement de coalition conservateur-libéraux-démocrates, formé en mai 2010, déclara son engagement en faveur de la création d'un réseau à grande vitesse. En janvier 2012 on approuva la construction de la première phase entre Londres et Birmingham, avec une date d'ouverture prévue de 2026. Le 11 février 2021, l'approbation royale a été donnée pour la construction de la phase 2A, de West Midlands (Birmingham) à Crewe, avec une ouverture aux passagers prévue entre 2029 et 2033. Le HS2 tire son nom du fait d'être la deuxième ligne à grande vitesse d'Angleterre, après la ligne transmanche. Le projet est revu à la baisse par le gouvernement britannique en novembre 2021 ; la deuxième branche, de Birmingham à Leeds, est abandonnée. Depuis son lancement en 2009, le projet n'avait cessé de multiplier les retards et les coûts. Ces derniers, estimés initialement à 36 milliards de livres sterling, ont grimpé à 106 milliards, tandis que la ligne ne devrait pas être achevée avant les années 2040. (fr)

HS2 sarà costruita a forma di "Y" con Londra in basso, Birmingham al centro, Leeds in alto a destra e Manchester in alto a sinistra.
