Kilburn (Brent) to Old Oak Common/No 4 | Structure Structure of the HS2 Phase One Environmental Statement The Environmental Statement (ES) documentation comprises: Non-technical summary (NTS) - which provides a summary in non-technical language of the Proposed Scheme, the likely significant environmental effects of the Proposed Scheme, both beneficial and adverse, and the means to avoid or reduce the adverse effects; Volume 1: Introduction to the Environmental Statement and the Proposed Scheme. This describes High Speed Two (HS2), and the environmental impact assessment process, the approach to consultation and engagement, details of the permanent features and generic construction techniques as well as a summary of main strategic and route-wide alternatives and local alternatives (prior to 2012) considered; Volume 2: Community forum area reports and map books - 26 reports and associated map books providing a description of the Proposed Scheme and of environmental effects in each area; Volume 3: Route-wide effects - provides an assessment of the effects of the Proposed Scheme where it is not practicable to describe them within the CFA descriptions in Volume 2; Volume 4: Off-route effects - provides an assessment of the off-route effects of the Proposed Scheme; Volume 5: Appendices and map books - contains supporting environmental information and associated map books; and Glossary of terms and list of abbreviations - contains terms and abbreviations, including units of measurement, used throughout the ES documentation. v CFA Report - Kilburn (Brent) to Old Oak Common/No 4 | Structure vi CFA Report - Kilburn (Brent) to Old Oak Common/No 4 | Introduction 1 Introduction 1.1 Introduction to HS2 1.1.1 High Speed Two (HS2) is a new high speed railway proposed by the Government to connect major cities in Britain. 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.
