Stations in London, Birmingham, Leeds, Manchester, South Yorkshire and the East Midlands will be served by high-speed trains running at speeds of up to 360kph (225mph). 1.1.2 HS2 is proposed to be built in two phases. Phase One, the subject of this ES, will involve the construction of a new railway line of approximately 230km (143 miles) between London and Birmingham. Construction will begin in 2017 and the line will become operational by 2026; with a connection to the West Coast Main Line (WCML) near Lichfield and to the existing HS1 railway line in London. 1.1.3 During Phase One, beyond the dedicated high-speed track, high-speed trains will connect with and run on the existing WCML to serve passengers beyond the HS2 network to destinations in the north. A connection to HS1 will also allow some services to access that high-speed line through east London and Kent and connect with mainland Europe via the Channel Tunnel. 1.1.4 Phase Two will involve the construction of lines from Birmingham to Leeds and Manchester; with construction commencing approximately 2023, and planned to be operational by 2033. 1.1.5 Section 4 of Volume 1 describes the anticipated operational characteristics of HS2, including the anticipated frequency of train services. As Volume 1 shows, the frequency of trains is expected to increase over time and to increase further upon opening of Phase Two. In assessing the environmental effects of the Proposed Scheme the anticipated Phase Two operational frequency has been used. For further detail of the anticipated operation of the Proposed Scheme in the Primrose Hill to Kilburn (Camden) area (CFA3), see Section 2.4. 1.1.6 The Government believes that the HS2 network should link to Heathrow and its preferred option is for this to be built as part of Phase Two. However, the Government has since taken the decision to pause work on the Heathrow link until after 2015 when it expects the Airports Commission to publish its final report on recommended options for maintaining the country’s status as an international aviation hub.
