It will deliver improved services for rail users through the relief of crowding, faster Crossrail – a general introduction journeys and the provision of a range of new direct journey opportunities. The project will also 1.1 Crossrail is a major new cross-London rail link project that has been developed to serve London have wider social and economic benefits for London and southeast England. and southeast England. Crossrail will support and maintain the status of London as a world city 1.4 It should be noted that the need for Crossrail is defined elsewhere in the Environmental by providing a world-class transport system. The project includes the construction of a twin-bore Statement, principally in Volume 1 chapter 4. tunnel on an east–west alignment under central London and the upgrading of national rail lines to the east and west of central London. Crossrail – route overview 1.2 The project will enable the introduction of a range of new and improved rail journeys into and 1.5 Crossrail’s route has four distinct sections: a Central route section in central London and, outside through London. It includes the construction of seven central area stations, providing interchange central London, the Western, Northeastern and Southeastern route sections as shown in fig 1.1. with London Underground, national rail and London bus services, and the upgrading and renewal 1.6 In the west, Crossrail will use the Great Western Main Line between Maidenhead and of existing stations outside central London. Crossrail will provide fast, efficient and convenient Westbourne Park. The existing 25 kV overhead electrification between Paddington and Airport rail access to the West End and the City by linking existing routes from Shenfield and Abbey Junction will be extended to Maidenhead, and bridges will be altered as necessary. The main Wood in the east to Maidenhead and Heathrow in the west. infrastructure changes are the construction of a flyover structure (the Stockley flyover) to allow Crossrail trains to join the existing tunnelled spur to Heathrow, and a rail underpass or ‘dive- under’ west of Acton Yard. A new line, within the existing railway corridor, will be provided between Langley and West Drayton. Enhancements will also be made to stations, the most significant works being at Ealing Broadway, Southall, Hayes & Harlington, West Drayton, Slough and Maidenhead. New stabling sidings at Old Oak Common, West Drayton and west of Maidenhead station are proposed. 1.7 The Central route section will consist largely of a twin-bore tunnel beneath central London with portals at Royal Oak in the west, Pudding Mill Lane in the northeast and Victoria Dock Road in the southeast. The Central section extends from a point around 200 m west of A40 Westway to a point around 500 m east of the portal at Pudding Mill Lane in the northeast and a point just east of Poplar Dock and A1206 Prestons Road in the Isle of Dogs in the southeast. New stations and associated structures such as ventilation shafts will be provided along this part of the route. 1.8 On the Northeastern route section, Crossrail will use the Great Eastern Main Line between Pudding Mill Lane and Shenfield. The main infrastructure changes are a new train maintenance depot west of Romford station and the reinstatement of a track between Goodmayes and Chadwell Heath. Some stations will be enhanced, notably Ilford and Romford. This section of the route already has 25 kV overhead electrification. New stabling facilities will be provided at Gidea Park. 1.9 The Southeastern route section runs between a point east of the Isle of Dogs station and the eastern terminus at Abbey Wood, where Crossrail will serve a reconstructed station. Crossrail will operate in a twin-bore tunnel to Victoria Dock portal, where it will serve a reconstructed station at Custom House. From there the route will follow the alignment that is used at present by the North London Line through the Connaught Tunnel to Silvertown. At North Woolwich, a new twin-bore tunnel to Plumstead, referred to as the Thames Tunnel, will pass beneath the River Thames. Two new tracks will be provided between Plumstead and a point east of Abbey Wood station to Fig. 1.2 Crossrail will serve the City of London accommodate Crossrail services on the North Kent Line corridor. This route will be provided 5 VOLUME 8A with 25 kV overhead electrification on the Crossrail lines. New stabling sidings will be provided Structure of the transport assessment at Gidea Park. 1.10 Because of the size of the study, the transport assessment is reported as an appendix to the Crossrail Environmental Statement in four volumes. This document, Volume 8a, sets out the methodology and principal findings of the transport assessment. Volumes 8b, 8c and 8d set out the traffic and transport impacts, respectively, for the Central, Western and Eastern route sections as shown on fig 1.1. The Eastern section comprises the Northeastern and Southeastern route sections.
