Line 6 of the Beijing Subway (Chinese: 北京地铁6号线; pinyin: běijīng dìtiě liùhào xiàn) 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 Caofang in Chaoyang District. It is planned that the line will be extended by 2015 in both directions: to Shijingshan to the west, and to Tongzhou to the east. With these extensions, 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. 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. The line uses 1500V overhead catenary as opposed to 750V third rail used on other lines.
Line 6 was originally planned to be a east west line passing under Chaoyang Avenue continuing straight westward. However this alignment will make Line 6 tunnel extremely close to the Forbidden City in its central section. Issues of historic conservation and protection of the alignment were raised. 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. 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.
Route and Stations
Construction is planned in three phases, the first phase in central Beijing, followed by extensions into the eastern and western suburbs. Line 6 is projected to have a short term volume of 700,000 passengers per day and a long term daily passenger traffic of 1.4 million passengers. Though due to its alignment through some of Beijing's densest residential neighborhoods and paralleling the overcapacity and busy Line 1, some industry leaders believe that the average daily passenger flow of the line may exceeded 1.4 million sooner than expected. Within the first few months of operation weekday ridership was at 320,000 passengers. However by 2014, daily ridership has risen to 700,000 with sections operating at 100% capacity during rush hour. Authorities responded by adding more trains and shortening headway to reduce crowding.
In Phase I, Line 6 runs 30 km from Wulu in Haidian District to Caoying in Tongzhou District following Linglong Road, Sanlihe Road, Chaoyang North Rd., the west bank of the Grand Canal, and Grand Canal East Road. Of the 20 planned stations, 12 will offer transfer connections to other lines. Construction began in December 2007 and was completed in 2012. Total investment for Phase I was estimated at ¥19.7 billion.
Planned stations from west to east (and transfer stations other lines -- bold denotes lines in operation; italic denotes lines under construction):
Line 6 in Phase I was originally slated to have elevated tracks for 7 km, east of the 5th Ring Road, from Dingfuzhuang and Changying. After residents along the route raised concerns about train noise, planners reconsidered and ultimately decided to keep all of Phase I under ground.
Phase II (eastern extension)
In Phase II, Line 6 will be extended further east by about 12 km through 7 stations from Caofang to Dongxiaoying in the Tongzhou New City. It is planned to have express and local services using passing tracks at select stations. Planned stations, from west to east:
Like Phase I, Phase II track will be entirely underground.
Phase III (western extension)
In 2011, city planning authorities proposed to detach from the planned Line S1 of the Beijing Suburban Railway (Mentougou Line) and add to Line 6 as a western extension, an 8.9-km section with five stations from Pingguoyuan to Tiancun. The revision, made in response to public concerns about electromagnetic radiation from maglev trains on Line S1 and to expand Pingguoyuan into mass transit hub, was formalized and submitted to the National Development and Reform Commission for review in March 2012.
The planned stations, from west to east, are:
Three of the five stations will be below ground and the other two stations will be elevated above ground.
- As of October 2007, Line 6 was planned to feature both express and local stations, but those plans have not been incorporated into the construction of Phase I.
- On March 22, 2010, the tunneling work on Line 6 commenced near Shilipu in Chaoyang District.
- As of November 2010, plans for Phase II contained distinct express and local stations.
