The Beijing Subway is the rapid transit system of Beijing Municipality that consists of 27 lines including 22 rapid transit lines, two airport rail links, one maglev line and two light rail tram lines, and 490 stations. The rail network extends 836 km (519 mi) across 12 urban and suburban districts of Beijing and into one district of Langfang in neighboring Hebei province. In December 2023, the Beijing Subway became the world's longest metro system by route length, surpassing the Shanghai Metro. Since then the system has returned to second place, but with the opening of new lines in December 2024, it will retake the title. With 3.8484 billion trips delivered in 2018 (10.544 million trips per day) and single-day ridership record of 13.7538 million set on July 12, 2019, the Beijing Subway was the world's busiest metro system in the years immediately prior to the outbreak of the COVID-19 pandemic.

The Beijing Subway opened in 1971 and is the oldest metro system in mainland China and on the mainland of East Asia. Before the system began its rapid expansion in 2002, the subway had only two lines. The existing network still cannot adequately meet the city's mass transit needs. Beijing Subway's extensive expansion plans call for 998.5 km (620.4 mi) of lines serving a projected 18.5 million trips every day when Phase 2 Construction Plan finished (around 2025). The most recent expansion came into effect on December 30, 2023, with the openings of extensions to Line 11, Line 16, and Line 17.

Fare schedules

Single-ride fare
The Beijing Subway charges single-ride fare according to trip distance for all lines except the two airport express lines.

• For all lines except the two airport express lines, fares start at ¥3 for a trip up to 6 km in distance, with ¥1 added for the next 6 km, for every 10 km thereafter until the trip distance reaches 32 km, and for every 20 km beyond the first 32 km. A 40 km trip would cost ¥7.
• The Capital Airport Express has a fixed fare of ¥25 per ride.
• The Daxing Airport Express is the only line to maintain class-based fares with ordinary class fare varying with distance from ¥10 to ¥35 and business class fare fixed at ¥50 per ride.

Same-station transfers are free on all subway lines except the two Airport Express lines, the Xijiao Line and the Yizhuang T1 Line, which require the purchase of a new fare when transferring to or from those lines.

Fare free riders
Children below 1.3 metres (51 in) in height ride for free when accompanied by a paying adult. Senior citizens over the age of 65, individuals with physical disabilities, retired revolutionary cadres, police and army veterans who had been wounded in action, military personnel and People's Armed Police can ride the subway for free.

Unlimited-rides fare
Since January 20, 2019, riders can purchase unlimited rides fare tickets using the Yitongxing (亿通行) APP on smartphones, which generates a QR code with effective periods of one to seven days.

Previous fare schedules
On December 28, 2014, the Beijing Subway switched from a fixed-fare schedule to the current distance-based fare schedule for all lines except the Capital Airport Express. Prior to the December 28, 2014, fare increase, passengers paid a flat rate of RMB(¥) 2.00 (including unlimited fare-free transfers) for all lines except the Capital Airport Express, which cost ¥25, The flat fare was the lowest among metro systems in China. Before the flat fare schedule was introduced on October 7, 2007, fares ranged from ¥3 to ¥7, depending on the line and number of transfers.

Fare collection

Each station has two to fifteen ticket vending machines. Ticket vending machines on all lines can add credit to Yikatong cards. Single-ride tickets take the form of an RFID-enabled flexible plastic card.

Discounts for Yikatong card users
Monthly expenditure	Net expenditure after credit rebate	Net discount
¥50	¥50	0%
¥100	¥100	0%
¥150	¥140	6.67%
¥200	¥165	17.5%
¥250	¥190	24%
¥300	¥215	28.3%
¥350	¥240	31.4%
¥400	¥265	33.75%
¥450	¥315	30%
¥500	¥365	27%

Passengers must insert the ticket or scan the card at the gate both before entering and exiting the station. The subway's fare collection gates accept single-ride tickets and the Yikatong fare card. Passengers can purchase tickets and add credit to Yikatong card at ticket counters or vending machines in every station. The Yikatong, also known as Beijing Municipal Administration & Communication Card (BMAC), is an integrated circuit card that stores credit for the subway, urban and suburban buses and e-money for other purchases. The Yikatong card itself must be purchased at the ticket counter. To enter a station, the Yikatong card must have a minimum balance of ¥3.00. Upon exiting the system, single-ride tickets are inserted into the turnstile, which are reused by the system.

Beijing Subway fare media

A single-ride farecard

To prevent fraud, passengers are required to complete their journeys within four hours upon entering the subway. If the four-hour limit is exceeded, a surcharge of ¥3 is imposed. Each Yikatong card is allowed to be overdrawn once. The overdrawn amount is deducted when credits are added to the card.

Yikatong card users who spend more than ¥100 on subway fare in a calendar month will receive credits to their card the following month. After reaching ¥100 of spending in one calendar month, 20% of any further spending up to ¥150 will be credited. When spending exceeds ¥150, 50% of any further spending up to ¥250 will be credited. Once expenditures exceed ¥400, further spending won't earn any more credits. The credits are designed to ease commuters' burdens of fare increases.

Beginning in June 2017, single-journey tickets could be purchased via a phone app. A May 2018 upgrade allowed entrance via scanning a QR code from the same app.

Since the COVID-19 pandemic, a name and Chinese Resident Identity Card number must be entered when buying single-ride tickets for contact tracing purposes. This measure has been criticized for increasing the time spent buying tickets.

Lines in operation

Beijing Subway lines generally follow the checkerboard layout of the city. Most lines through the urban core (outlined by the Line 10 loop) run parallel or perpendicular to each other and intersect at right angles.

Future expansion

Phase II

According to the Phase 2 construction plan approved by the NDRC in 2015, the length of Beijing Subway will reach 998.5 km (620.4 mi) when the Phase 2 construction finished. By then, public transit will comprise 60% of all trips. Of those, the subway will comprise 62%. The adjustment of the Phase 2 construction plan was approved by the NDRC on December 5, 2019. Which altered and expanded some projects in the Phase 2 construction plan. Including adjusting alignments of Line 22 and Line 28 and additional projects such as the Daxing Airport Line north extension, the west section of Line 11 and transforming Line 13 into two lines, 13A and 13B.

Owner and operators

The Beijing Subway is owned by the Beijing Municipal People's Government through the Beijing Infrastructure Investment Co., LTD, (北京市基础设施投资有限公司 or BIIC), a wholly owned subsidiary of the Beijing State-owned Assets Supervision and Administration Commission (北京市人民政府国有资产监督管理委员会 or Beijing SASAC), the municipal government's asset holding entity.

The Beijing Subway was originally developed and controlled by the Central Government. The subway's construction and planning was headed by a special committee of the State Council. In February 1970, Premier Zhou Enlai handed management of the subway to the People's Liberation Army, which formed the PLA Rail Engineering Corp Beijing Subway Management Bureau. In November 1975, by order of the State Council and Central Military Commission the bureau was placed under the authority of Beijing Municipal Transportation Department.

On April 20, 1981, the bureau became the Beijing Subway Company, which was a subsidiary of the Beijing Public Transportation Company.

In July 2001, the Beijing Municipal Government reorganized the subway company into the Beijing Subway Group Company Ltd., a wholly city-owned holding company, which assumed ownership of all of the subway's assets. In November 2003, the assets of the Beijing Subway Group Company were transferred to the newly created BIIC.

The Beijing Subway has five operators:

1. The main operator is the wholly state-owned Beijing Mass Transit Railway Operation Corp. (北京市地铁运营有限公司 or Beijing Subway OpCo), which was formed in the reorganization of the original Beijing Subway Group Company in 2001, and operates 15 lines: Lines 1, 2, 5–10, 13, 15, Batong line, Changping line, Fangshan line, Yizhuang line and S1 line.
2. The Beijing MTR Corp. (北京京港地铁有限公司 or Beijing MTR), a public–private joint venture formed in 2005 by and among Beijing Capital Group, a state company under Beijing SASAC (with 49% equity ownership), MTR Corporation of Hong Kong (49%), and BIIC (2%), and operates four lines: Lines 4, 14, 16 and Line 17 and Daxing line.
3. The Beijing Metro Operation Administration Corp., Ltd. (北京市轨道交通运营管理有限公司 or BJMOA), a subsidiary of Beijing Metro Construction Administration Corporation Ltd. (北京市轨道交通建设管理有限公司 or BJMCA) also under Beijing SASAC, became the third company to obtain operation rights for the Beijing Subway in 2015. The BJMOA operates the Yanfang line, Daxing Airport Express, and Line 19. Its corporate parent, BJMCA, is a general contractor for Beijing Subway construction.
4. The Beijing Public Transit Tramway Co., Ltd. (北京公交有轨电车有限公司), formed in 2017, is a wholly owned subsidiary of Beijing Public Transport Corporation (北京公共交通控股（集团）有限公司 or BPTC) that operates the Xijiao line. Its corporate parent, BPTC, is the city's main public bus operator.
5. The Beijing City Metro Ltd. (北京京城地铁有限公司), also branded as "Capital Metro" (京城地铁) in their official logo, operates the Capital Airport Express. Beijing City Metro Ltd. is a joint venture established on February 15, 2016, between Beijing Subway OpCo (51%) and BII Railway Transportation Technology Holdings Company Limited (49%)(京投轨道交通科技控股有限公司), a Hong Kong listed company (1522.HK) controlled by BIIC. On March 27, 2017, Beijing City Metro Ltd. acquired a 30-year right to operate the Capital Airport Express and sections of the Dongzhimen subway station.

All subway train sets run on 1,435 millimetres (56.5 in) standard gauge rail, except the maglev trains on Line S1, which run on a maglev track. Beijing Subway operates Type B trains on most lines. However, due to increasing congestion on the network, high capacity Type A trains are increasingly being used. Additionally, Type D trains are being used in express subway lines.

Until 2003 nearly all trains were manufactured by the CRRC Changchun Railway Vehicles Co., Ltd., now a division of the CRRC. The newest Line 1 trains and those on Lines 4, 8, Batong, Changping and Daxing are made by CRRC Qingdao Sifang Co., Ltd. Line S1's maglev trains were produced by CRRC Tangshan.

The Beijing Subway Rolling Stock Equipment Co. Ltd., a wholly owned subsidiary of the Beijing Mass Transit Railway Operation Corp. Ltd., provides local assemblage, maintenance and repair services.

• 
  Most Beijing Subway rolling stock, such as this DKZ5 Line 13 train, run on 1,435 millimetres (56.5 in) standard gauge track, drawing 750V direct current (DC) electrical power from the third rail. Line 13, like most lines, use six-car Type-B train sets.
• 
  Lines 14 and 16 trains run on standard gauge track and draw 1500V DC power from overhead electrical lines. The DKZ53 train on Line 14 pictured above uses Type-A cars, which unlike the more common Type-B cars, are 3.1 meters longer and 20 cm wider, have 10 sets of doors instead of 8 sets of doors, greater passenger capacity and higher top speed.
• 
  The four-car train sets of the Capital Airport Express have linear motors of instead of rotary motors. Capital Airport Express trains draw 750V DC power from the third rail, and are propelled using the aluminum strip, a "fourth rail", between the main track. Capital Airport Express trains sets are lighter than subway cars with rotary motors and can reach a top speed of 110 km/h (68 mph).
• 
  Line S1 features low-to-mid speed maglev trains that run on a maglev track and use 1,500 V DC power. The S1 maglev trains have six cars per train and can reach a top speed of 100 km/h (62 mph).
• 
  The light rail transit trams on the Xijiao (Western Suburban) line run on standard gauge track and draw power 750V alternating current (AC) electrical power from overhead lines. The Xijiao line uses five-car trams and can reach a top speed of 70 km/h (43 mph).

Subway rolling stock are maintained at depots such as the Wuliqiao Depot for Line 6.

Automated lines

There will be 6 fully automated lines at the level of GoA4, including 4 lines in operation (the Yanfang line, Line 17 and Line 19 and the Daxing Airport Express) and 2 lines under construction (Line 3 and Line 12), using domestically developed communications-based train control systems.

History

Schema showing the development of the Beijing Subway from 1971 to 2018

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.

At that time, 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 university 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 original proposal called for deep subway tunnels that can better serve military functions. Between Gongzhufen and Muxidi, shafts as deep as 120 m (390 ft) were being dug. The world's deepest subway station at the time in the Kyiv Metro was only 100 m (330 ft) deep. But Beijing's high water table and high pressure head of ground water which complicated construction and posed risk of leakage, and along with the inconvenience of transporting passengers long distances from the surface, led the authorities to abandon the deep tunnel plan in May 1960 in favor of cut-and-cover shallow tunnels some 20 m (66 ft) below the surface.

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

Yuquanlu Station, Opened on August 5, 1971. The first phase of the Beijing subway project groundbreaking ceremony was held west of Yuquanlu Road.

Many areas of Beijing's city walls were torn down during the construction of the subway. The route of the initial subway line was slightly altered to save the Qianmen gate.

Construction began on July 1, 1965, at a groundbreaking ceremony attended by several national leaders including Zhu De, Deng Xiaoping, and Beijing 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 and began trial operations 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 Gucheng 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.

Initially, the subway hosted guest visits. 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 early 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 could purchase tickets. The line was 10.7 km (6.6 mi) in length, had 10 stations and operated more than 60 train trips per day with a minimum wait time of 14 minutes. On August 15, the initial line was extended to Yuquan Lu and had 13 stations over 15.6 km (9.7 mi). On November 7, the line was extended again, to Gucheng Lu, and had 16 stations over 22.87 km (14.21 mi). The number of trains per day rose to 100. Overall, the line delivered 8.28 million rides in 1971, averaging 28,000 riders per day.

From 1971 to 1975, the subway was shut down for 398 days for political reasons. On December 27, 1972, the riders no longer needed to present credential letters to purchase tickets. In 1972, the subway delivered 15 million rides and averaged 41,000 riders per day. In 1973, the line was extended to Pingguoyuan and reached 23.6 km (14.7 mi) in length with 17 stations and 132 train trips per day. The line delivered 11 million rides in 1973, averaging 54,000 riders per day.

Despite its return to civilian control in 1976, the subway remained prone to closures due to fires, flooding, and accidents. Annual ridership grew from 22.2 million in 1976 and 28.4 million in 1977 to 30.9 million in 1978, and 55.2 million in 1980.

1981–2000: two lines for two decades

On April 20, 1981, the Beijing Subway Company, then a subsidiary of the Beijing Public Transportation Company, was organized to take over subway operations. On September 15, 1981, the initial line passed its final inspections, and was handed over to the Beijing Subway Company, ending a decade of trial operations. It had 19 stations and ran 27.6 kilometres (17.1 miles) from Fushouling in the Western Hills to the Beijing railway station. Investment in the project totaled ¥706 million. Annual ridership rose from 64.7 million in 1981 and 72.5 million in 1982 to 82 million in 1983.

Paper tickets for Lines 1 & 2

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.

Entrance to the Wangfujing Station on Line 1. The Wangfujing station opened in 1999 as part of Line 1's eastward extension from Fuxingmen.

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 Sihuidong 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 to 2008, the city planned to invest ¥63.8 billion (US$7.69 billion) in subway projects and build an ambitious "three ring, four horizontal, five vertical and seven radial" subway network. 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 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.

As part of the urban re-development for the 2008 Olympics, the subway system was significantly expanded.In the summer of 2008, in anticipation of the Summer Olympic Games, three new lines—Line 10 (Phase 1), Line 8 (Phase 1) and the Capital Airport Express—opened on July 19. 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 operated throughout the night from August 8–9, 2008 to accommodate the Opening Ceremonies of the Olympic Games, and is extending evening operations of all lines by one to three hours (to 1-2 a.m.) through the duration of the Games. 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–present: 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 elevated lines 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 Xijiao Lines.

On December 30, 2010, Lines 15, Changping, Fangshan, Yizhuang and Daxing, all suburban lines, commenced operation.

In 2010, Beijing's worsening traffic congestion prompted city planners to move the construction of several lines from the 13th Five Year Plan to the 12th Five Year Plan. This meant Lines 8 (Phase III), Line 3, Line 12, Line 16, the Yanfang line, as well as additional lines to Changping District and Tiantongyuan were to begin construction before 2015. Previously, Lines 3, 12 and 16 were being planned for the more distant future. On December 30, 2010, five suburban lines: Lines 15 (Phase I from Wangjingxi 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 Forest Park South Gate to Huilongguan Dongdajie, the opening of Line 9 in southwest Beijing from Beijing West railway station to Guogongzhuang (except Fengtai Dongdajie, 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. In the same year, the Beijing government unveiled an ambitious expansion plan envisioning the subway network to reach a 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. Ridership reached 2.18 billion in 2011.

Beijing Television interviewed subway officials on December 30, 2012, when over 40 new stations were opened, and the subway temporarily surpassed the Shanghai Metro to be the longest in the world, only to be surpassed by Shanghai again a year later.

In February 2012, the city government confirmed that Lines Line 3, Line 12, Line 17, and Line 19 were under planning as part of Phase II expansion. Retroactively implying that the original three ring, four horizontal, five vertical and seven radial plan was part of Phase I expansion. Line 17 was planned to run north–south, parallel and to the east of Line 5, from Future Science Park North to Yizhuang Zhanqianqu South. Line 19 was planned to run north–south, from Mudanyuan to Xin'gong.

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 Andeli Beijie), 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, for several months, as the world's longest metro. The subway delivered 2.46 billion rides in 2012.

On May 5, 2013, the Line 10 loop was completed with the opening of the Xiju-Shoujingmao section 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). On December 28, 2013, two sections were added to Line 8, which extended the line north to Zhuxinzhuang and south to Nanluoguxiang. In 2013, the subway delivered 3.209 billion rides, an increase of 30% from the year before.

On December 28, 2014, the subway network expanded by 62.2 km (38.6 mi) to 18 lines and 527 km (327 mi) with the opening of Line 7, the eastern extension of line 6 (from Caofang to Lucheng), the eastern section of line 14 (from Jintai Lu to Shangezhuang), and the western extension of line 15 (from Wangjingxi to Qinghua Donglu Xikou). At the same time, the ¥2 flat-rate fare was replaced with a variable-rate fare (a minimum of ¥3), to cover operation costs. In 2014, the subway delivered 3.387 billion rides, an increase of 5.68% from the year before. Average daily and weekday ridership also set new highs of 9.2786 million and 10.0876 million, respectively.

From 2007 to 2014, the cost of subway construction in Beijing rose sharply from ¥0.571 billion per km to ¥1.007 billion per km. The cost includes land acquisition, compensation to relocate residents and firms, actual construction costs and equipment purchase. In 2014, city budgeted ¥15.5 billion for subway construction, and the remainder of subway building costs was financed by the Beijing Infrastructure Investment Co. LTD, a city-owned investment firm.

In 2014, Beijing planning authorities assessed mass transit monorail lines for areas of the city in which subway construction or operation is difficult. Straddle beam monorail trains have lower transport capacity and operating speed (60 km/h or 37 mph) than conventional subways, but are quieter to operate, have smaller turning radius and better climbing capability, and cost only one-third to one-half of subways to build. According to the initial environmental assessment report by the Chinese Academy of Rail Sciences, the Yuquanlu Line was planned to have 21 stations over 25 km (16 mi) in western Beijing. The line was to begin construction in 2014 and would take two years to complete. The Dongsihuan Line (named for the Eastern Fourth Ring Road it was to follow) was planned to have 21 stations over 33.7 km (20.9 mi).

In early 2015, plans for both monorail lines were shelved indefinitely, due to low capacity and resident opposition. The Yuquanlu Line remains on the city's future transportation plan, and it will be built as a conventional underground subway line. The Dongsihuan Line was replaced by the East extension of Line 7.

On December 26, 2015, the subway network expanded to 554 km (344 mi) with the opening of the section of Line 14 from Beijing South railway station to Jintai Lu (11 stations; 16.6 km (10.3 mi)), Phase II of the Changping line from Nanshao to Changping Xishankou (5 stations; 10.6 km or 6.6 mi), Andelibeijie station on Line 8, and Datunlu East station on Line 15. Ridership in 2015 fell by 4% to 3.25 billion due to a fare increase from a flat fare back to a distance based fare.

With the near completion of the three ring, four horizontal, five vertical and seven radial subway network, work began on Phase II expansion projects. These new extensions and lines will be operational in 2019~2021. On December 9, 2016, construction started on 126 km (78 mi) of new line with the southern extension of Batong Line, the southern extension of Changping line, the Pinggu line, phase one of the New Airport line, and Line 3 Phase I breaking ground. The northern section of Line 16 opened on December 31, 2016. Ridership reached a new high of 3.66 billion. On December 30, 2017, a one-station extension of Fangshan Line (Suzhuang – Yancun East), Yanfang line (Yancun Dong - Yanshan), Xijiao line (Bagou - Fragrant Hills) and S1 line (Shichang – Jin'anqiao) were opened. On December 30, 2018, the western extension of Line 6 (Jin'anqiao – Haidian Wuluju), the South section of Line 8 (Zhushikou – Yinghai), a one-station extension on Line 8 North section (Nanluoguxiang – National Art Museum), a one-station extension on Yizhuang line (Ciqu – Yizhuang Railway Station) were opened. On September 26, 2019, the Daxing Airport Express (Phase 1) (Caoqiao - Daxing Airport) was opened. On December 28, 2019, the eastern extension of Line 7 (Jiaohuachang-Huazhuang) and the southern extension of Batong line (Tuqiao-Huazhuang) were opened.

On January 24, 2020, the day after a lockdown was declared in the city of Wuhan to contain the outbreak of COVID-19 in China, the Beijing Subway began testing body temperature of passengers at the 55 subway stations including the three main railway stations and capital Airport. Temperature checks expanded to all subway stations by January 27.

On April 4, 2020, at 10:00am, Beijing Subway trains joined in China's national mourning of lives lost in the COVID-19 pandemic, by stopping for three minutes and sounding their horns three times, as conductors and passengers stood in silence. To control the spread of COVID-19, certain Line 6 trains were outfitted with smart surveillance cameras that can detect passengers not wearing masks.

New wayfinding to Line 13

In May 2020, the Beijing Subway began to pilot a new style of wayfinding on Line 13 and Airport Express. However, since then the new designs were not rolled out to other lines or even new lines that opened afterward.

On December 31, 2020, the middle section of Line 16 (Xi Yuan-Ganjia Kou), the northern section of the Fangshan line (Guogongzhuang-Dongguantou Nan(S)), and the Yizhuang T1 line tram were opened.

On August 26, 2021, Line 7 and Batong line extended to Universal Resort station. On August 29, 2021, through operation of Line 1 and Batong line started. On December 31, 2021, the initial sections of Line 11 (Jin'anqiao - Shougang Park), Line 17 (Shilihe - Jiahuihu), Line 19 (Mudanyuan - Xingong); extensions of Capital Airport Express (Dongzhimen - Beixinqiao), Changping line (Xierqi - Qinghe Railway Station), Line S1 (Jin'anqiao - Pingguoyuan), Line 16 (Ganjiakou - Yuyantan Park East Gate); and the central sections of Line 8 (Zhushikou - National Art Museum) and Line 14 (Beijing South Railway Station - Xiju) were opened. With the completion of the central sections of Line 8 and 14 along with the final section of Line S1 marks the completion of the three ring, four horizontal, five vertical and seven radial subway network plan (retroactively named Phase I expansion).

On July 30, 2022, stations Beitaipngzhuang, Ping'anli, Taipingqiao, Jingfengmen of Line 19 were opened. On December 31, 2022, the extension of Line 16 (Yuyantan Park East Gate - Yushuzhuang) was opened.

On January 18, 2023, in the morning and evening peak hours of the workday, the cross-line operation of Fangshan Line and Line 9 began. On February 4, 2023, the extension of Changping Line (Qinghe Railway Station - Xitucheng) was opened.

Automated audio announcements for incoming trains are available in all lines. On all lines, station names are announced in Mandarin Chinese and English. Under subway regulations, riders with mobility limitations may obtain assistance from subway staff to enter and exit stations and trains, and visually impaired riders may bring assistance devices and guide dogs into the subway.

Cellular network coverage

Mobile phones can currently be used throughout the network. In 2014, Beijing Subway started upgrading cellular networks in the Beijing subway to 4G. In 2016, the entire subway network has 4G coverage. Since 2019, 5G coverage is being rolled out across the network.

Commercial facilities

In the 1990s a number of fast food and convenience stores operated in the Beijing Subway. In 2002, fourteen Wumart convenience stores opened in various Line 2 stations.

After witnessing the Daegu subway fire in February 2003, the Beijing Subway gradually removed the 80 newsstands and fast food restaurants across 39 stations in Line 1 and Line 2. The popular underground mall at Xidan station was closed. This is in contrast other systems in China which added more station commerce as they started to rapidly expand their networks. Since the implementation of this policy new lines did not have any station commerce upon opening.

Passengers consistently complained that the lack of station commerce in the Beijing Subway is inconvenient. In the early 2010s, Beijing Subway started reversing some of these policies. Vending machines selling drinks and snacks has gradually introduced inside stations since 2013. Later machines with of common items such as flowers, earphones, masks, etc. were also introduced. In 2013, China Resources Vanguard and FamilyMart expressed interest in opening convenience stores in the Beijing Subway but this never materialized.

On July 25, 2021, Lawson opened a store in the paid area of Hepingli Beijie Station.

The survey report on passenger satisfaction in subway services since 2018 shows that more than 70% of passengers want convenience stores in subway stations, especially for various hot and cold drinks, ready-to-eat food, and bento meals. In December 2020, "the deployment of 130 convenient service facilities at subway stations" was listed as a key project for the Beijing municipal government. On July 25, 2021, Beijing Subway selected three stations, Hepingli Beijie station of Line 5, Qingnian Lu station of Line 6, and Caishikou station of Line 7, to carry out a pilot program of opening convenience stores. Since December 2021, a rapid rollout of station commerce began on a large scale across the network with a variety of commercial establishments such as bookstores, pharmacies, flower shops and specialty vendors being constructed inside stations.

Information hotline and app

The Beijing Subway telephone hotline was initiated on the eve of the 2008 Summer Olympic Games to provide traveler information, receive complaints and suggestions, and file lost and found reports. The hotline combined the nine public service telephones of various subway departments. On December 29, 2013, the hotline number was switched from (010)-6834-5678 to (010)-96165 for abbreviated dialing. In December 2014, the hotline began offering fare information, as the subway switched to distance-based fare. The hotline has staffed service from 5 am to midnight and has automated service during unstaffed hours.

The Beijing Subway has an official mobile application and a number of third-party apps.

English station names

According to the related rules released in 2006, all the place names, common names and proper names of subway stations and bus stops should use uppercase Hanyu Pinyin. For example, Nanlishi Lu Station should be written as NANLISHILU Station. However, names of venues can use English translation, such as Military Museum.

According to the translation standard released in December 2017, station names of rail transit and public transport have to follow the laws.

Since December 2018, Beijing Subway has changed the format of names of the new subway stations every year. On the subway map of December 2018, the station names used Roman script, and it gave consideration to English writing habit and pronunciation. The format changed to verbatim in December 2019, where the positions (East, South, West and North) were written in Hanyu Pinyin and an English abbreviation was added to them.

Since December 31, 2021, Beijing Subway has started using new station name format. The Pinyin "Zhan" is used instead of English word "Station" on the light box at the subway entrance. This caused a strong disagreement. Citizens criticized it, making comments like "Chinese do not need to read and foreigners cannot read it". Some of the landmark named stations uses Chinese name, Hanyu Pinyin and English translation. Station names ending with positions no longer add English abbreviation. Some of the stations that used English translation names (such as Shahe Univ. Park, Life Science Park and Liangxiang Univ. Town) changed to Hanyu Pinyin only (The new station names are Shahe Gaojiaoyuan, Shengming Kexueyuan and Liangxiang Daxuecheng).

System upgrades

Capacity

A crowded transfer corridor on Line 10.

With new lines drawing more riders to the network, the subway has experienced severe overcrowding, especially during the rush hour. Since 2015, significant sections of Lines 1, 4 – Daxing, 5, 10, 13, Batong and Changping are officially over capacity during rush hour. By 2019, Lines 1, 2, 4, 5, 6 and 10 all have daily weekday ridership's of over 1 million passengers a day each. In short term response, the subway upgraded electrical, signal and yard equipment to increase the frequency of trains to add additional capacity. Peak headways have been reduced to 1 min. 43 sec. on Line 4; 1 min. 45 sec. on Lines 1/Batong, 5, 9, and 10; 2 min. on Lines 2, 6, 13 and Changping; 2 min. and 35 sec. on Line 15; 3 min. 30 sec. on Line 8; and 15 min. on the Airport Express. The Beijing Subway is investigating the feasibility of reducing headways of Line 10 down to 1 min 40 seconds.

Lines 13 and Batong have converted 4-car to 6-car trains. Lines 6 and 7 have longer platforms that can accommodate 8-car type B trains, while lines 14, 16, 17 and 19 use higher capacity wide-body type A trains (all mentioned except Line 14 use eight-car trains). New lines that cross the city center such as Line 3 and Line 12, now under construction, will also adopt high capacity 8-car type A trains with a 70 percent increase in capacity over older lines using 6 car type B. When completed these lines are expected to greatly relieve overcrowding in the existing network.

The articulated cars of Line 5 trains have greater carrying capacity.

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. Some of these stations have built queuing lines outside the stations to manage the flow of waiting passengers. As of August 31, 2011, 25 stations mainly on Lines 1, 5, 13, and Batong have imposed such restrictions. 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. The number of stations with passenger flow restrictions reached 110 in January 2019, affecting all lines except Lines 15, 16, Fangshan, Yanfang and S1. Lines 4, 5, 10 and 13 strategically run several empty train runs during rush hour bound for specific stations help clear busy station queues. Counter peak flow express trains started operating on Line 15, Changping and Batong to minimize line runtimes and allow the existing fleet size to serve more passengers during peak periods. Additionally, investigations are being carried out on Line 15 and Yizhuang for upgrading to 120 km/h operations.

Transfers

At Wangjing West, an interchange station for Lines 13 and 15, passengers transferring between the two lines must pass through a lengthy transfer corridor that includes a pedestrian footbridge.

Interchange stations that permit transfers across two or more subway lines receive heavy traffic passenger flow. The older interchange stations are known for lengthy transfer corridors and slow transfers during peak hours. The average transfer distance at older interchange stations is 128 m (420 ft) The transfer between Lines 2 and 13 at Xizhimen once required 15 minutes to complete during rush hours. In 2011, this station was rebuilt to reduce the transfer distance to about 170 m (560 ft) long. 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 m (207 ft). Many of the newer interchange stations including Guogongzhuang (Lines 9 and Fangshan), Nanluoguxiang (Lines 8 and 6), Zhuxinzhuang (Changping and Line 8), Beijing West railway station (Lines 9 and 7), National Library (Lines 9 and 4), Yancun East (Fangshan Line and Yanfang Line) feature cross platform transfers. Nevertheless, longer transfer corridors must still be used when the alignment of the lines do not permit cross-platform transfer. The transfer corridors between Lines 1 and 9 at the Military Museum, which opened on December 23, 2013, are 160 m (520 ft) in one direction and just under 300 m (980 ft) in the other.

Safety

Security check

Since the 2008 Olympics, security checks of riders and bags have become mandatory on the Beijing Subway.

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.

Accidents and incidents

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.

Subway culture

Logo

The logo of the Beijing Subway contains the subway's abbreviation, B.G.D.

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 pinyin abbreviation for "北京高速电车" (pinyin: Běijīng gāosù diànchē; lit. 'Beijing high-speed electric carriage').

Subway Culture Park
