Line 7 (Beijing Subway)

  (Redirected from Line 7, Beijing Subway)

Line 7 of the Beijing Subway (Chinese: 北京地铁7号线; pinyin: běijīng dìtiě qīhàoxiàn) is a rapid transit line in Beijing. It runs parallel and to the south of Line 1 and Batong line, from the Beijing West railway station in Fengtai District to Jiaohuachang in Chaoyang District. Construction began in January 2010.[4] It started test runs in September 2014 with full operation beginning on December 28, 2014.[5] Like Line 6, Line 7 provides additional relief to the overcapacity Line 1 adding another east-west trunk line to the Beijing Subway network.[6]

RouteEdit

Phase I of Line 7 has 21 stations, currently 20 stations are opened (Shuangjing on Line 7 is not opened yet). It is planned to have 9 more stations after Phase II (Eastern extension) opened in December 2019.

The line uses 8-car Type B trains.[7][8]

The line was originally slated to have 15 stations, from the Beijing West railway station to Baiziwan.[9] A revised plan approved by the Planning Committee of the Beijing Municipal government called for 21 stations over 23.7 km (14.7 mi)[5], ending in Jiaohuachang.[10]

PlanningEdit

Line 6 was originally conceived in 1973 as a "pan-handle" shaped route incorporating the central sections of today's Lines 6 and 7.[11] In 1983 Line 6 was dissolved into two distinct lines. The section under Guang'anmen, Luomashi, Zhushikou and Guangqumen Streets and the "handle" branch to Fengtai became Line 7. The rest of the loop with a new south eastern extension to what was at the time the Beijing Jiaohuachang (Coking Plant) complex became Line 6.[12] Line 7 was later revised westward to terminate at a new major railway station called Beijing West railway station and Line 9 taking over servicing Fengtai.[13] When Beijing West railway station started construction in the early 1990s space was set aside for a subway station allowing Cross-platform interchange for the future Lines 7 and 9.[14] By 1993 the planned section of Line 6 heading to Coking Plant complex was revised as an eastern extension of Line 7, forming the alignment built today.[15]

In 2013, planners revised the design of Line 7 from using the standard 6 car trains to 8 car trains after performing a detailed transport study of the Fatou area. Fatou's population projections were upgraded from 100,000 to 220,000 people and be a significant employment hub in the future. Planners decided that 6 cars trains would have insufficient capacity for the new demand projections. Line 7 was originally planned to use 1500 V DC overhead lines to power the longer subway trains. However, the already completed platforms at Beijing West railway station assumed the line would use a 750 V DC 3rd rail system like Beijing's legacy subway lines and built with vertical clearance for such. The line ultimately used a 1500 V DC 3rd rail system as a compromise.[6]
