The High Speed 2 (HS2) project in England is a major infrastructure project aimed at creating a high-speed rail link between London and various cities in the north of England. The planned route will run over several phases, with the first phase providing a link between London and Birmingham, followed by later extensions to Manchester and Leeds. HS2 is designed to reduce travel times, increase the capacity of the rail network and promote economic development in various regions. However, the project has also received criticism regarding its costs, environmental impact and the potential expropriation of land. The progress and implementation of the project continue to be the subject of public debate and political decisions in the UK.
