The Beijing Subway is a rapid transit rail network that serves the urban and suburban districts of Beijing municipality. The subway is owned by the city of Beijing and has two operators, the wholly state-owned Beijing Mass Transit Railway Operation Corp., which operates 14 lines, and the Beijing MTR Corp., a public-private joint venture with the Hong Kong MTR, which manages the other three lines.
The subway is the oldest metro system in mainland China. The first line opened in 1969, and it has grown to 17 lines, 227 stations[a] and 456 km (283 mi) of track in operation, making it the second longest subway system in the world after the Seoul Metropolitan Subway. The subway ranks third in the world in annual ridership after those of Tokyo and Seoul, with 2.46 billion trips delivered in 2012. With a average weekday ridership of 8.539 million and single-day ridership record of 10.276 million passengers was set on March 8, 2013.
The Beijing Subway's flat fare of ¥2.00 (about USD0.32) per ride with free transfers on all lines except for the Airport Express, is the lowest among all rapid transit systems in China. The low fare is made possible by annual subsidies of about ¥2 billion by the Beijing Municipal Government for subway operations, or about ¥0.81 (USD0.13) per ride.
The subway has undergone rapid expansion as all but two of the 17 lines entered service since 2002. The most recent expansion came into effect on May 5, 2013 with the opening of Line 14 and the completion of the 57 km (35 mi) Line 10 loop. The existing network still cannot adequately meet the city's mass transit needs and extensive expansion plans call for 19 lines and over 708 km (440 mi) of track in operation by 2015 and 1,050 km (650 mi) of track by 2020.
A flat fare of RMB(¥) 2.00 with unlimited transfers applies to all lines except the Airport Express, which costs ¥25. Children below 1.2 metres (47 in) in height ride for free when accompanied by a paying adult.
Before the flat fare was introduced on October 7, 2007, fares ranged from ¥3 to ¥7, depending on the line and number of transfers. The flat fare is the lowest among metro systems in China. Other major Chinese subway systems set fares based on distance traveled.
Fares are collected through automatic fare collection (AFC) machines that accept single-ride tickets and the One Card Through Card or Yikatong, an integrated circuit card (ICC card) that can store credit for multiple rides. Riders can purchase tickets and add credit to Yikatong at ticket counters and vending machines in every station. Yikatong is also accepted on nearly all urban and suburban buses, and can be used as e-money for other purchases. The use of tickets hand checked by clerks was phased out, ending on June 9, 2008.
Hours of operation 
The subway is generally closed after midnight, unless a special occasion prompts extended operating hours. The first trains depart terminals at around 5 am and the last leave at around 11 pm. The Airport Express train starts at around 6 am.
Lines generally follow the checkerboard layout of the city. Most lines run parallel or perpendicular to each other and intersect at right angles.
Lines serving the urban core:
- Line 1, a straight east-west line underneath Chang'an Avenue, which bisects the city through Tiananmen Square. Line 1 connects major commercial centres, Xidan, Wangfujing, Dongdan and the Beijing CBD.
- Line 2, a rectangular loop line, traces the Ming-era city wall that once surrounded the inner city, and stops at 11 of the wall's former gates (ending in men), now busy intersections, as well as the Beijing Railway Station.
- Line 4, a mainly north-south line running west of city centre with stops at the Summer Palace, Old Summer Palace, Peking and Renmin Universities, Zhongguancun Technology Park, National Library, Beijing Zoo, Xidan and Beijing South Railway Station.
- Line 5, a straight north-south line just east of the city centre. It passes the Temple of Earth, Lama Temple and the Temple of Heaven.
- Line 6, a nearly straight east-west line running parallel and to the north of Line 1. It passes through the city centre north of Beihai Park.
- Line 8, a north-south line directly north of city centre from Huilongguan through the Olympic Green to Gulou Dajie.
- Line 9, a north-south line running west of Line 4 from the National Library through the Beijing West Railway Station to Guogongzhuang, southwest of city centre.
- Line 10, a larger loop route outside of Line 2 that connects every other line running through the city centre.
Lines to outlying suburbs:
- Line 13 arcs across suburbs north of the city and channels commuters to Xizhimen and Dongzhimen, at the northwest and northeast corners of Line 2.
- Line 14 runs west from Xiju on Line 10, across the Yongding River, to Zhangguozhuang in Fengtai District.
- Line 15 branches off Line 13 at Wangjing West and runs northeast to suburban Shunyi District.
- Batong Line extends Line 1 eastward from Sihui to suburban Tongzhou District.
- Changping Line branches off Line 13 at Xi'erqi and runs north to suburban Changping District.
- Daxing Line extends Line 4 south to suburban Daxing District.
- Fangshan Line extends Line 9 south from Guogongzhuang to Fangshan District in the southwestern suburbs.
- Yizhuang Line extends from Line 5's southern terminus to the Yizhuang Economic & Technological Development Zone in the southeastern suburbs.
- Airport Express connects the Beijing Capital International Airport, 27 km (17 mi) northeast of the city, with Line 10 at Sanyuanqiao and Lines 2 and 13 at Dongzhimen.
1953–1965: origins 
The subway was proposed in September 1953 by the city's planning committee and experts from the Soviet Union. After the end of the Korean War, Chinese leaders turned their attention to domestic reconstruction. They were keen to expand Beijing's mass transit capacity but also valued the subway as an asset for civil defense. They studied the use of the Moscow Metro to protect civilians, move troops and headquarter military command posts during the Battle of Moscow, and planned the Beijing Subway for both civilian and military use.
The Chinese lacked expertise in building subways and drew heavily on Soviet and East German technical assistance. In 1954, a delegation of Soviet engineers, including some who had built the Moscow Metro, was invited to plan the subway in Beijing. From 1953 to 1960, several thousand Chinese students were sent to the Soviet Union to study subway construction. An early plan unveiled in 1957 called for one ring route and six other lines with 114 stations and 172 km (107 mi) of track. Two routes vied for the first to be built. One ran east-west from Wukesong to Hongmiao, underneath Changan Avenue. The other ran north-south from the Summer Palace to Zhongshan Park, via Xizhimen and Xisi. The former was chosen due to more favorable geological foundation and greater number of government bureaus served. The second route would not be built until construction on Line 4 began forty years later.
The deterioration of relations between China and Soviet Union disrupted subway planning. Soviet experts began to leave in 1960, and were completely withdrawn by 1963. In 1961, the entire project was halted temporarily due to severe hardships caused by the Great Leap Forward. Eventually, planning work resumed. The route of the initial line was shifted westward to create an underground conduit to move personnel from the heart of the capital to the Western Hills. On February 4, 1965, Chairman Mao Zedong personally approved the project.
1965–1981: the slow beginning 
Construction began on July 1, 1965, at a ceremony attended by national leaders including Zhu De, Deng Xiaoping, and mayor Peng Zhen. The most controversial outcome of the initial subway line was the demolition of the Beijing's historic inner city wall to make way for the subway. Construction plans for the subway from Fuxingmen to the Beijing Railway Station called for the removal of the wall, as well as the gates and archery towers at Hepingmen, Qianmen, and Chongwenmen. Leading architect Liang Sicheng argued for protecting the wall as a landmark of the ancient capital. Chairman Mao favored demolishing the wall over demolishing homes. In the end, Premier Zhou Enlai managed to preserve several walls and gates, such as the Qianmen gate and its arrow tower by slightly altering the course of the subway.
The initial line was completed in time to mark the 20th anniversary of the founding of the People's Republic on October 1, 1969. It ran 21 km (13 mi) from the army barracks at Fushouling to the Beijing Railway Station and had 16 stations. This line forms parts of present-day Lines 1 and 2. It was the first subway to be built in China, and predates the metros of Hong Kong, Seoul, Singapore, San Francisco, and Washington, D.C., but technical problems would plague the project for the next decade.
On November 11, 1969, an electrical fire killed three people, injured over 100 and destroyed two cars. Premier Zhou Enlai placed the subway under the control of the People's Liberation Army in 1970, but reliability problems persisted. On January 15, 1971, the initial line began operation on a trial basis between the Beijing Railway Station and Gongzhufen. Single ride fare was set at ¥0.10 and only members of the public with credential letters from their work units were permitted entry into the subway. The line delivered 8.28 million rides in 1971 but remained under trial operation throughout the Cultural Revolution. From 1971 to 1975, the subway was shut down for 398 days for political reasons. Despite its return to civilian control in 1976, the subway remained prone to closures due to fires, flooding, and accidents.
1981–2000: two lines for two decades 
On September 15, 1981, after a decade of trial operation, the initial line was opened to full public use. It had 19 stations and ran 27.6 km (17.1 mi) from Fushouling in the Western Hills to the Beijing Railway Station. Investment in the project totaled ¥706 million. The subway was placed under the management of the Beijing Subway Company, then a subsidiary of the Beijing Public Transportation Company. Annual ridership reached 72.5 million in 1982.
On September 20, 1984, a second line was opened to the public. This horseshoe-shaped line was created from the eastern half of the initial line and corresponds to the southern half of the present-day Line 2. It ran 16.1 km (10.0 mi) from Fuxingmen to Jianguomen with 16 stations. Ridership reached 105 million in 1985. On December 28, 1987, the two existing lines were reconfigured into Lines 1, which ran from Pingguoyuan to Fuxingmen and Line 2, in its current loop, tracing the Ming city wall. Fares doubled to ¥0.20 for single-line rides and ¥0.30 for rides with transfers. Ridership reached 307 million in 1988. The subway was closed from June 3–4, 1989 during the suppression of the Tiananmen Square demonstrations. In 1990, the subway carried more than one million riders per day for the first time, as total ridership reached 381 million. After a fare hike to ¥0.50 in 1991, annual ridership declined slightly to 371 million.
On January 26, 1991, planning began on the eastward extension of Line 1 under Chang'an Avenue from Fuxingmen. The project was funded by a 19.2 billion yen low-interest development assistance loan from Japan. Construction began on the eastern extension on June 24, 1992, and the Xidan station opened on December 12, 1992. The remaining extension to Sihui East was completed on September 28, 1999. National leaders Wen Jiabao, Jia Qinglin, Yu Zhengsheng and mayor Liu Qi were on hand to mark the occasion. The full-length of Line 1 became operational on June 28, 2000.
Despite little track expansion in the early 1990s, ridership grew rapidly to reach a record high of 558 million in 1995, but fell to 444 million the next year when fares rose from ¥0.50 to ¥2.00. After fares rose again to ¥3.00 in 2000, annual ridership fell to 434 million from 481 million in 1999.
2001–2008: planning for the Olympics 
In the summer of 2001, the city won the bid to host the 2008 Summer Olympics and accelerated plans to expand the subway. From 2002 and 2008, the city planned to invest ¥63.8 billion (US$7.69 billion) in subway projects. Work on Line 5 had already begun on September 25, 2000. Land clearing for Lines 4 and 10 began in November 2003 and construction commenced by the end of the year. Most new subway construction projects were funded by loans from the Big Four state banks. Line 4 was funded by the Beijing MTR Corporation, a joint-venture with the Hong Kong MTR. To achieve plans for 19 lines and 561 km (349 mi) by 2015, the city planned to invest a total of ¥200 billion ($29.2 billion).
The next additions to the subway were surface commuter lines that linked to the north and east of the city. Line 13, a half loop that links the northern suburbs, first opened on the western half from Huilongguan to Xizhimen on September 28, 2002 and the entire line became operational on January 28, 2003. Batong Line, built as an extension to Line 1 to Tongzhou district, was opened as a separate line on December 27, 2003. Work on these two lines had begun respectively in December 1999 and 2000. Ridership hit 607 million in 2004.
Line 5 came into operation on October 7, 2007. It was the city's first north-south line, extending from the Songjiazhuang in the south to Tiantongyuan in the north. On the same day, subway fares were reduced from between ¥3 and ¥7 per trip, depending on the line and number of transfers, to a single flat fare of ¥2 with unlimited transfers. The lower fare policy caused the Beijing Subway to run a deficit of ¥600 million in 2007, which was expected to widen to ¥1 billion in 2008. The Beijing municipal government covered these deficits to encourage mass transit use, and reduce traffic congestion and air pollution. On a total of 655 million rides delivered in 2007, the government's subsidy averaged ¥0.92 per ride.
In the summer of 2008, in anticipation of the Summer Olympic Games, three new lines—Line 10, the Olympic Branch Line and the Airport Express—were opened on July 19 for trial operation. The use of paper tickets, hand checked by clerks for 38 years, was discontinued and replaced by electronic tickets that are scanned by automatic fare collection machines upon entry and exit of the subway. Stations are outfitted with touch screen vending machines that sell single-ride tickets and multiple-ride Yikatong fare cards. The subway set a daily ridership record of 4.92 million on August 22, 2008, the day of the Games' closing ceremony In 2008, total ridership rose by 75% to 1.2 billion.
2008–2013: rapid expansion 
After the Chinese government announced a ¥4 trillion economic stimulus package in November 2008, the Beijing urban planning commission further expedited subway building plans, especially for surface light rail to suburban districts that are cheaper to build. In December 2008, the commission moved completion dates of the Yizhuang and Daxing Lines to 2010 from 2012, finalized the route of the Fangshan Line, and unveiled the Changping and Western Suburban Lines.
Line 4 started operation on September 28, 2009, bringing subway service to much of western Beijing. It is managed by the Hong Kong MTR through a joint venture with the city. In 2009, the subway delivered 1.457 billion rides, 19.24% of mass transit trips in Beijing.
On December 30, 2010, five suburban lines: Lines 15 (Phase I from Wangjing West to Houshayu except Wangjing East Station), Changping, Fangshan (except Guogongzhuang Station), Yizhuang (except Yizhuang Railway Station), and Daxing, commenced operation. The addition of 108 km (67 mi) of track, a nearly 50% increase, made the subway the fourth longest metro in the world. One year later, on December 31, 2011, the subway surpassed the New York City Subway to become the third longest metro in revenue track length with the extension of Line 8 north from the Olympic Green to Huilongguan, the opening of Line 9 in southwest Beijing from Beijing West Railway Station to Guogongzhuang (except Fengtai Dongdajie Station, which opened on October 12, 2012), the extension of the Fangshan Line to Guogongzhuang, and the extension of Line 15 from Houshayu to Fengbo in central Shunyi.
On December 30, 2012, Line 6 (Phase I from Haidian Wuluju to Caofang), the extension of Line 8 from Beitucheng south to Gulou Dajie (except Andelibeijie Station), the remainder of Line 9 (except Military Museum Station) and the remainder of the Line 10 loop (except the Xiju-Shoujingmao section and Jiaomen East Station) entered service. The addition of 69.8 km (43 mi) of track increased the network length to 442 km (275 mi) and allowed the subway to overtake the Shanghai Metro as the world’s longest metro.
On May 5, 2013, the Line 10 loop was completed with the opening of the Xiju-Shoujingmao secton and the Jiaomen East Station. The 57 km (35 mi) loop line became the longest underground subway loop in the world. On the same day, the first section of Line 14 from Zhangguozhuang to Xiju also entered operation, ahead of the opening of the Ninth China International Garden Expo in Fengtai District. The subway's total length reached 456 km (283 mi).
Future lines 
There are at least seven lines under construction with work on several more lines set to begin in 2013. The network is set to reach almost 500 km (310 mi) by the end of 2013. According to expansion plans announced in January 2011, the subway network in 2015 is expected to reach track density of 0.51 km per km2 (0.82 mi per sq. mi.) inside the Fifth Ring Road where residents would on average have to walk 1 km (0.62 mi) to the nearest subway station.
The new lines will significantly expand the subway's coverage, especially south and west of the city. Line 7 will run parallel and to the south of Line 1. Line 8 will be extended south to Line 6. Line 16 will run parallel and to the west of Line 4. Line 14 will be extended from the southwest to the northeast. The Western Suburban and Yanfang Lines will connect outlying districts to the Beijing Subway.
To address the city's worsening traffic congestion problem, in December 2010 city planners moved the construction of several lines from the 13th Five Year Plan to the 12th Five Year Plan. This means Lines 8 (Phase III), 3, 12, 16, the Yanfang Line, as well as additional lines to Changping, Tiantongyuan, and Haidian will begin construction before 2015. Subway planning authorities had indicated that Lines 3, 11, 12 and 16 were being planned for the more distant future.
In January 2010, the government of Shijingshan District disclosed plans for a Line 11 in western Beijing that would traverse the Beijing Capital Steel complex and intersect with Lines 1 and 4. Construction is set to begin in 2020. Line 17 is planned to run underneath Guanghua Road in the Central Business District with transfers to Lines 4 and 5. In February 2012, the city government confirmed that six new lines, including Lines 3, 12, R1, R2 and R3, were under planning.

Rolling stock 
All subway trains run on 1,435 millimetres (56.5 in) standard gauge rail and draw power from the 750V DC third rail, with the exception of trains on Lines 6 and 14, which use overhead wires. All lines operate 6-car train sets with a maximum speed of 80 km/h (50 mph), except Line 6, which uses 8-car sets, and the Airport Express, which has 4-car sets, which can reach 100 km/h (62 mph) and 110 km/h (68 mph) respectively.
Until 2003 nearly all trains were manufactured by the Changchun Railway Vehicles Company Ltd., now a subsidiary of the China CNR Corporation. Currently, all trains on Lines 2, 5, 8, 10, 13, Airport Express and older models on Line 1 are made by Changchun RVC, which is under contract to supply trains for Lines Yizhuang, 9 and 10 (Phase II). The newest Line 1 trains and those on Lines 4, 8, Batong, Changping and Daxing are made by Qingdao Sifang Locomotive & Rolling Stock Co., a subsidiary of China South Locomotive and Rolling Stock Industry Corp..
System upgrades 
Increasing Capacity 
With new lines drawing more riders to the network and the fare reduction making rides more affordable, the subway has experienced severe overcrowding, especially during the rush hour. In response, the subway upgraded signal equipment to increase the frequency of trains and added to the capacity of subway trains. The minimum wait-time has been reduced to 2 min. on Line 2; 2 min. 15 sec. on Line 1; 3 min. on Lines 4, 5, 13, and Batong; 3.5 min. on Line 10; and 15 min. on the Airport Express. Lines 13 and Batong have converted 4-car to 6-car trains. Lines 6 and 7 have longer platforms that can accommodate 8-car B size trains, while line 14 will use high capacity wide-body A size trains in 6 car sets. Also lines 3, 11, 12, 16 and Haidian Shanhou under planning may adopt 8-car A size trains.
Despite these efforts, during the morning rush hour, conductors at line terminals and other busy stations must routinely restrict the number of passengers who can board each train to prevent the train from becoming too crowded for passengers waiting at other stations down the line. As of August 31, 2011, 25 stations mainly on Lines 13, Batong, 1 and 5, have imposed such restrictions. Some of these stations have built queuing lines outside the stations to manage the flow of waiting passengers. By January 7, 2013, 41 stations on Lines 1, 2, 5, 13, Batong, and Changping had instituted passenger flow restrictions during the morning rush hour.
Shortening Transfers 
Interchange stations that permit transfers across two or more subway lines receive heavy traffic passenger flow. The older interchange stations are notorious for lengthy transfer corridors and slow transfers during peak hours. Average transfer distance an older interchange stations is 128 meters  The longest transfer, between Lines 2 and 13, at Xizhimen, was over 200 meters long and required 15 minutes to complete during rush hours. In 2011, this station was rebuilt to reduce the transfer distance. There are plans to rebuild other interchange stations such as Dongzhimen.
In newer interchange stations, which are designed to permit more efficient transfers, the average transfer distance is 63 meters. Many of the newer interchange stations including Guogongzhuang Station (Lines 9 and Fangshan), Nanluoguxiang (Lines 8 and 6), Zhuxinzhuang (Changping and Line 8), Beijing West Station (Lines 9 and 7), and National Library (Lines 9 and 4) feature cross platform transfers. Nevertheless, longer transfer corridors must still be used when the alignment of the lines do not permit cross-platform transfer.
Cellular Network Coverage 
Access for the Physically Disabled 
Each station is equipped with ramps, lifts, or elevators to facilitate wheelchair access. Newer model train cars now provide space to accommodate wheelchairs. Automated audio announcements for incoming trains are available in all lines except for Line 1. On all lines, station names are announced in Mandarin Chinese and English.
Automatic Fare Collection System 
Passenger searches 
To ensure public safety during the 2008 Summer Olympic and Paralympic Games, the subway initiated a three-month heightened security program from June 29 to September 20, 2008. Riders were subject to searches of their persons and belongings at all stations by security inspectors using metal detectors, X-Ray machines and sniffer dogs. Items banned from public transportation such as "guns, ammunition, knives, explosives, flammable and radioactive materials, and toxic chemicals" were subject to confiscation. The security program was reinstituted during the 2009 New Year Holiday and has since been made permanent through regulations enacted in February 2009. Only bags are generally X-rayed (as of 2012), riders are checked only occasionally .
Emergency planning 
After witnessing several serious subway accidents in South Korea (e.g. Daegu subway fire in February 2003), the subway removed all shops and vendors from the inside of stations and installed self-illuminating exit signs to facilitate emergency evacuation. The popular underground mall at the Xidan station was closed.
The subway was plagued by numerous accidents in its early years, including a fire in 1969 that killed six people and injured over 200. But its operations have improved dramatically and there have been few reported accidents in recent years. Most of the reported fatalities on the subway are the result of suicides. Authorities have responded by installing doors on platforms of newer lines.
There have been several reported fatal incidents at subway construction sites in recent years. On October 8, 2003, the collapse of steel beams at the construction site of Line 5's Chongwenmen Station killed three workers and injured one. On March 29, 2007, the construction site at the Suzhoujie Station on Line 10 collapsed, burying six workers. On June 6, 2008, prior to the opening of Line 10, a worker was crushed to death inside an escalator in Zhichunlu Station when an intern turned on the moving staircase. On July 14, 2010, two workers were killed and eight were injured at the construction site of Line 15's Shunyi Station when the steel support structure collapsed on them. On June 1, 2011, one worker was killed when a section of Line 6 under construction in Xicheng District near Pinganli collapsed. A collapse of an escalator at the Beijing Zoo station on July 5, 2011, caused the death of one 13-year-old boy and injuries to 28 others.
The subway's logo, a capital letter "G" encircling a capital letter "D" with the letter "B" silhouetted inside the letter D, was designed by Zhang Lide, a subway employee, and officially designated in April 1984. The letters B, G, and D form the abbreviation for Běijīng gāosù diànchē or "Beijing high-speed electric carriage".
Beijing Suburban Railway 
The Beijing Suburban Railway mass transit rail system complements the subway and provides commuter train service to outlying suburban districts and counties. Six "S"-numbered lines have been planned. The Beijing Suburban Railway is managed separately from the subway and has a different fare structure. Line S2, opened August 6, 2008, runs from the Beijing North Railway Station to Yanqing County, and provides direct urban rail access to the Great Wall at Badaling. The Beijing North Station is located near the subway stop at Xizhimen (Subway Lines 2, 4, 13).
