Line 6 of the Beijing Subway () is a rapid transit rail line in central Beijing. The line currently runs parallel to the north of Line 1 and the Batong Line, from Wulu in Haidian to Lucheng in Chaoyang District. It serves important residential areas such as Changying, Chaoqing, and Dingfuzhuang, in addition to important commercial and business areas such as Financial Street and Beijing CBD.〔 It is planned that the line will be extended by 2015 to Shijingshan to the west. With this extension, it is expected to be 50.67 km long with 32 stations. Line 6 uses Beijing Subway's highest capacity rolling stock to date featuring 8-car size B train sets accommodating 1,960 people, compared to the standard 6 cars found on other lines except the Airport Express line which has 4-car train sets.〔(Chinese) (''法制晚报'' ) January 20, 2010〕 It is also the fastest in the subway system, with trains capable of reaching the speed of 100 km/h compared to 80 km/h on other lines. Stations to the east of the 3rd Ring Road to Tongzhou are more widely spaced, the furthest being 4 km apart. These factors allows passengers to travel the whole line in just 48 minutes. Line 6 also has the deepest station in the network, Dongsi Station, which is 34 meters underground.〔 ==Planning== Line 6 was originally planned to be an east west line passing under Chaoyang Avenue continuing straight westward. However this alignment will make the central section of Line 6 tunnel extremely close to the Forbidden City. Issues of historic conservation and protection were raised against the proposed alignment. To avoid damaging cultural relics in the area, the entire western and middle section of line 6 was shifted 1.5 km northward to Ping'an Avenue, forming the route of Line 6 today.〔(【引用サイトリンク】title=2012年九月份科普论坛报告会 )〕 Line 6 started construction on December 8, 2007 as one of the "horizontal" east west lines of the "three-ring, four horizontal and five vertical and seven radial" Beijing Subway masterplan. Line 6 was originally planned to terminate at Cishousi Station with the Mentougou Low Speed Maglev Line continuing the line westward. However issues of low of capacity and electromagnetic radiation concerns of Maglev technology, the Mentougou Maglev section between Cishousi and Pingguoyuan station was replaced by a new Phase 3 western extension of Line 6. Later the plan was revised with Line 6 being further extended westward beyond Pingguoyuan to Jin'anqiao station, paralleling the Mentougou Maglev Line. 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「Line 6, Beijing Subway」の詳細全文を読む スポンサード リンク
