Superlink was a proposal for a new UK railway network to connect London, the south-east Midlands, East Anglia, and south-east England. It was an alternative proposal from a group of senior railway managers, who played leading roles in other UK rail projects. It suggested changes and enhancements to the Crossrail network. The proponents of Superlink claimed Crossrail gives poor value for money and was unlikely to be built. They suggested that benefits of the Crossrail scheme, including relief of congestion on the public transportation network within London, had been overstated. Superlink was rejected. Crossrail received Royal Assent in 2007 and a funding agreement in 2008. ==2005 report== In a 2005 report, CLRL examined the proposal and rejected it on the following grounds: * The large number of branches and long distances would not be compatible with short and regular train intervals through the central tunnel, leading to performance problems and transmission of delay between parts of the network. * Although increased demand for commuting into London is predicted in the regions served, these are already planned to be catered for with less costly train lengthening. Also, development and planning policy in these regions seeks to achieve sustainable growth and local employment, with less reliance on long distance commuting. * CLRL found the cost estimates of Superlink to be unreliable, eroding a key claim that it would be easier to finance than Crossrail. The estimated construction cost is 55% greater. * Superlink would require construction of new track and possibly a depot and stations in the green belt between Barkingside, Shenfield and Harlow. This causes environmental and planning issues. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Superlink (railway network)」の詳細全文を読む スポンサード リンク
