The Glasgow Subway is an underground metro line in Glasgow, Scotland. Opened on 14 December 1896, it is the third-oldest underground metro system in the world after the London Underground and the Budapest Metro. It is the only heavy rail underground metro system in the British Isles outside London, and also the only one outside London which operates completely underground. It is also one of the very few railways in the world with a track running gauge of . Formerly a cable railway, the Subway was later electrified, but its twin circular lines were never expanded. The line was originally known as the Glasgow District Subway, but was later renamed Glasgow Subway Railway. It was so called when taken over by the Glasgow Corporation who renamed it the Glasgow Underground in 1936. Despite this rebranding, many Glaswegians continued to refer to the network as "the Subway". In 2003 the name "Subway" was officially readopted by its operator, the Strathclyde Partnership for Transport (SPT). A £40,000 study examining the feasibility of an expansion into the city’s south side is in progress.〔(【引用サイトリンク】url=http://www.spt.co.uk/Publications/interchange/issue09.html )〕 The system is not the oldest underground railway in Glasgow; that distinction belongs to a section of the Glasgow City and District Railway opened in 1863, now part of the North Clyde Line of the suburban railway network, which runs in a sub-surface tunnel under the city centre between High Street and west of Charing Cross. Another major section of underground suburban railway line in Glasgow is the Argyle Line, which was formerly part of the Glasgow Central Railway. == Route == The route is a loop almost long and extends both north and south of the River Clyde. The tracks have the unusual narrow gauge of , and a nominal tunnel diameter of , even smaller than that of the deep-level lines of the London Underground ( at their smallest); the rolling stock is considerably smaller. The system describes itself as two lines, the Outer Circle and Inner Circle, but this simply refers to the double track, having trains running clockwise and counterclockwise respectively around the same route although in separate tunnels. Stations use a variety of platform layouts including single island platforms, opposing side platforms and in some stations such as Hillhead one side and one island platform. The subway’s running lines are entirely underground, but the maintenance depot at Broomloan Road (located between the and stations) is above ground, as was the earlier depot, also at Govan. Prior to modernisation, trains used to be hoisted by crane onto and off the tracks. Modernisation brought the installation of points and a ramp between Govan and Ibrox where trains can exit the tunnel system to terminate for engineering, cleaning or storage. The system is owned and operated by the Strathclyde Partnership for Transport (SPT), formerly Strathclyde Passenger Transport, and carried 13.16 million passengers in the period 2005-06.〔(【引用サイトリンク】url=http://www.spt.co.uk/subway/facts.html#passengers )〕 The Subway has been policed by British Transport Police since 2007.〔'Police For Glasgow Subway', ''The Times'', 3 January 2007〕 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「Glasgow Subway」の詳細全文を読む スポンサード リンク
