HS2 meaning in Computing ?

Answer:

What is High Speed 2 mean?

High Speed 2 (HS2) is a planned high-speed railway network in the United Kingdom, with the first phase between London and Birmingham currently under construction. The project is in three phases. Phase 1 is under construction and phase 2a, Birmingham to Crewe, awaits funding approval. The specification has not yet been finalised for phase 2b, the Crewe to Manchester and Birmingham to Leeds legs. The railway will be the country's second high-speed line, the first being High Speed 1 (HS1) which connects London to the Channel Tunnel. With a "Y"-shaped network of track and a design speed of 400 km/h (250 mph), the new railway will link London with Birmingham, Manchester and Leeds. Some HS2 trains will be capable of operating on the existing classic network, reaching locations off the HS2 network using mixed HS2/classic network services.

High Speed 2 will provide upgrades to the terminal stations of London Euston, Manchester Piccadilly and Leeds, whereas Birmingham will be served by a new terminus known as Birmingham Curzon Street. Phase 1 will create a new high-speed line between London and Birmingham. Phase 2 will create two branches north from Birmingham on either side of the Pennines. Once completed, sixteen trains per hour are planned to use the line either wholly or in part.

The project has been subject to both support and opposition. Supporters of the project believe that HS2 will provide increased capacity and reliability to combat rising passenger numbers while driving 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.

The costs of HS2 were estimated in 2010 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 give a budget of £56.6 billion. Oakervee's review in 2019 estimated the project would cost between £80.7 billion and £106 billion in 2019 prices. After a judicial review on environmental grounds failed, construction on the line began in 2020. Tunnelling for the first phase began in 2021, and is expected to take around three and a half years.

Completion of the full project is still in doubt despite construction commencing on the first phase. The media reports a number of leaks of a government-backed review from the National Infrastructure Commission, suggesting the eastern leg of phase 2b, Birmingham to Leeds, should be permanently shelved in favour of upgrades to existing routes to the Midlands. Transport minister Grant Shapps, in an interview with the Financial Times in October 2021 relating to changes in the eastern leg of phase 2b, said: "We want to make sure we get trains to Leeds in a way that actually benefits people on the network and not blindly follow some plan invented 15 to 20 years ago which no longer benefits people". Shapps also stated: "Midlands Rail Hub and Northern Powerhouse Rail are things, they’ve been invented, they hadn't been when HS2 was first designed". The southern phase 1, London to Birmingham, received an amber/red rating from the government's Infrastructure and Projects Authority, which reported that: "successful delivery of the project is in doubt". It gave Phase 2b, the western Crewe to Manchester leg and eastern Birmingham to Leeds leg, a red 'unachievable' rating.
