DART Underground ((アイルランド語:DART Faoi Thalamh)), previously known as the ''Interconnector'', was a planned railway tunnel in Ireland, projected to run under the city centre of Dublin. The tunnel would allow for the expansion of the electrified DART and the Dublin Suburban Rail network, and connect Heuston Station with Pearse Station. In November 2011 the government announced that the project would be deferred until 2016 at the earliest.〔 A month later a Railway Order permitting the construction of the project was granted in December 2011 by An Bord Pleanála. On 22 September 2015, it was announced that the project had been cancelled in favour of a simpler alternative. In August 2014, Minister for Transport Paschal Donohoe TD was told that both the Dart Underground and Metro North projects would have had to rely on private funding if they were to be built. In 2010, the estimated projected cost for DART Underground was €4 billion, more than half of which was expected to be provided by a public private partnership arrangement. Mr Donohoe was told he had to decide on whether to proceed with DART Underground by 24 September 2015 when the Railway Order giving authority and planning approval expires. A High Court ruling reduced the period for which compulsory purchase order notices could be issued from seven years to 18 months. DART Underground would provide an underground link between the existing Northeast DART line between Malahide/Howth and Clontarf Road and the Western Rail line between Heuston and Hazelhatch, with new underground stations across Dublin's city centre at the Docklands, Pearse Station, St. Stephen's Green, Christchurch, and beneath Heuston Station. Despite this not being a very direct route, the decision by An Bord Pleanála specifically referred to a national policy requirement that the line be built through St. Stephen's Green. The project would also involve the construction of a new overground station at Inchicore. ==History== DART Underground was first proposed in 1972 in the "Transportation in Dublin" study conducted by An Foras Forbartha, an anteceding body to Forfás (sometimes erroneously referred to as the 'Dublin Transportation Study') as an underground rail link to connect the 3 main Dublin Railway Stations. In 1975 CIÉ commissioned the Dublin Rapid Rail Transportation Study〔(Environmental Impact Study Dart Underground 2010 History of )〕 and which recommended a 4 Phase plan including a prototypical Dart Underground. Phase 1 Upgrade and electrify Howth – Bray (completed 1984 as the DART). Phase 2 An Underground line from Connolly to Heuston. Rapid Transit tracks Heuston to Clondalkin overground. Spur to Tallaght from Clondalkin (a small part was completed in 2010 when Rapid Transit tracks were installed either side of Clondalkin) Phase 3 A short northerly spur off the Maynooth line to Blanchardstown and a short southerly spur to Broadstone. (The former was never completed but was partly revived in 2001 as Metro West before that was itself shelved in 2011 and the latter spur will be completed as Luas Cross City in 2018.) Phase 4 An underground tunnel from Broadstone to Sandymount. (This was later redesigned as Metro North from Drumcondra to St Stephen's Green and shelved indefinitely in 2011.) The DRRTS, if completed as envisaged in 1975, would have resulted in a cross shaped pair of tunnels in the city centre meeting at a central station in Temple Bar.〔(Environmental Impact Study Dart Underground 2010 History of )〕 The plan was next proposed in 2001 as an 'Interconnector' in the Platform For Change strategy report issued by the〔(Platform For Change Summary Report November 2001 )〕 now defunct Dublin Transportation Office or DTO. 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「DART Underground」の詳細全文を読む スポンサード リンク
