List of metro systems in the context of "Beijing"

The New York City Subway is a rapid transit system in New York City, serving four of the city's five boroughs: Manhattan, Brooklyn, Queens, and the Bronx. It is owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the state-run Metropolitan Transportation Authority (MTA). Opened on October 27, 1904, the New York City Subway is one of the world's oldest public transit systems, one of the most-used, and the one with the second-most stations after the Beijing Subway, with 472 stations in operation (423, if stations connected by transfers are counted as single stations).

The system has operated 24/7 service every day of the year throughout most of its history, barring emergencies and disasters. By annual ridership, the New York City Subway is the busiest rapid transit system in both the Western Hemisphere and the Western world, as well as the ninth-busiest rapid transit rail system in the world. The subway carried 2,040,132,000 unlinked, non-unique riders in 2024. Daily ridership has been calculated since 1985; the record, over 6.2 million, was set on October 29, 2015.

Budapest is the capital and most populous city of Hungary. It is Hungary's primate city with 1.7 million inhabitants and its greater metro area has a population of about 3.3 million, representing one-third of the country's population and producing above 40% of the country's economic output. Budapest is the political, economic, and cultural center of the country, among the ten largest cities in the European Union and the second largest urban area in Central and Eastern Europe. Budapest stands on the River Danube and is strategically located at the center of the Pannonian Basin, lying on ancient trade routes linking the hills of Transdanubia with the Great Plain.

Budapest is a global city, consistently ranked among the 50 most important cities in the world, belongs to the narrow group of cities with a GDP over US$100 billion, named a global cultural capital as having high-quality human capital, and is among the 35 most liveable cities in the world. The city is home to over 30 universities with more than 150,000 students, most of them attending large public research universities that are highly ranked worldwide in their fields, such as Eötvös Loránd University in natural sciences, Budapest University of Technology in engineering and technology, MATE in life sciences, and Semmelweis University in medicine. Budapest also hosts various international organizations, including several UN agencies, the WHO Budapest Centre, IOM regional centre, the EU headquarters of EIT and CEPOL, as well as the first foreign office of China Investment Agency. Budapest opened the first underground transit line on the European continent in 1896, which is still in use as M1 Millennium Underground, and today the fixed-track metro and tram network forms the backbone of Budapest's public transport system and transports 2.2 million people daily, making it a significant urban transit system.

The Paris Métro, short for Métropolitain, is a rapid transit system serving the Paris metropolitan area in France. A symbol of the city, it is known for its density within the capital's territorial limits, as well as its uniform architecture and historical entrances influenced by Art Nouveau. The system is 245.6 kilometres (152.6 mi) long, mostly underground, as well as its 321 stations of which 61 allow the riders to transfer between the sixteen lines (with an additional four under construction and one in project), all numbered 1 to 14, with two extra branches, 3bis and 7bis, named such as they are former parts of Lines 3 and 7 respectively. Three of these lines (1, 4 and 14) are fully automated, and the additional four are also planned as such. Lines are identified on maps by an individual number and an associated specific colour, all part of an official palette, with the traveling direction indicated by the terminus, the last stop on each line. All trains travel from one end of the line to the other, serving every station along the way. The Paris Métro is operated by the Régie autonome des transports parisiens (RATP), which also operates part of the RER (commuter standard train) network, most of the Francilian light rail lines and many bus routes around and within Paris itself.

It is the second-busiest metro system in Europe, as well as the twelfth-busiest in the world. It carried 1.476 billion passengers in 2024, roughly 4.04 million passengers a day, which makes it the most used public transport system in Paris. It is one of the densest metro systems in the world, with 244 stations within the 105.4 km (41 sq mi) of the City of Paris. Châtelet–Les Halles, with five Métro and three RER commuter rail lines, is one of the world's largest metro stations. The system generally has poor accessibility due to its old age (established 125 years ago) and because most of the current infrastructure was built before accessibility standards emerged, with few stations retrofitted since. On the flip side, all new infrastructure and rolling stock meets current accessiblity standards, including extensions of historic lines.

The Beijing Subway is the rapid transit system of Beijing Municipality that consists of 29 lines including 24 rapid transit lines, two airport rail links, one maglev line and two light rail tram lines, and 524 stations. The rail network extends 879 km (546 mi) across 12 urban and suburban districts of Beijing and into one district of Langfang in neighboring Hebei province. In December 2023, Beijing Subway became the world's longest metro system by route length, surpassing the Shanghai Metro. 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 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 15, 2024, with the openings of Line 3 and Line 12 and an extension of the Changping line.

Transport in China has experienced major growth and expansion in recent years. Although China's transport system comprises a vast network of transport nodes across its huge territory, the nodes tend to concentrate in the more economically developed coastal areas and inland cities along major rivers. The physical state and comprehensiveness of China's transport infrastructure tend to vary widely by geography. While remote, rural areas still largely depend on non-mechanized means of transport, urban areas boast a wide variety of modern options, including a maglev system connecting the city center of Shanghai with Shanghai Pudong International Airport. Airports, roads, and railway construction will provide a massive employment boost in China over the next decade.

Much of contemporary China's transport systems have been built since the establishment of the People's Republic in 1949. The railway, which is the primary mode of long distance transport, has seen rapid growth reaching 139,000 km (86,371 mi) of railway lines making it the second longest network in the world (2016). Prior to 1950, there were only 21,800 km (13,546 mi) of railway lines. The extensive rail network includes the longest and busiest HSR network in the world with 35,000 km (21,748 mi) of high-speed lines by year end 2019. While rail travel remained the most popular form of intercity transport, air travel has also experienced significant growth since the late 1990s. Major airports such as Beijing Capital International and Shanghai Pudong International being among the busiest in the world. At the end of 2017, there are some 34 metro systems in operation across China, including some of the largest and busiest subway networks in the world. Of the 12 largest metro networks in the world by length, seven are now in China. Additionally, many bus rapid transit, light rail and rapid transit lines are currently under construction, or in the planning stages across the country. The highway and road system also has gone through rapid expansion, resulting in a rapid increase of motor vehicle use throughout China. A government-led effort started in the 90s to connect the country by expressways via the National Trunk Highway System has expanded the network to about 97,000 km (60,273 mi) by the end of 2012 making China's the longest expressway network in the world.

The Shanghai Metro (Chinese: 上海地铁; pinyin: Shànghǎi Dìtiě; Shanghainese: Zaonhe Dithiq) is a rapid transit system in Shanghai, operating urban and suburban transit services to 14 of its 16 municipal districts and to the neighboring township of Huaqiao, in Kunshan, Jiangsu Province.

Forming the vast majority of the broader, multi-operator Shanghai rail transit network, the Shanghai Metro system is the world's second longest metro system by route length, totaling 808 kilometres (502 mi) and the second largest system by number of stations, with 506 stations across 19 lines (408, if stations connected by transfers are counted as single stations). It also ranks first in the world by annual ridership, with 3.88 billion rides delivered in 2019. The last daily ridership record was set on 9 March 2024, at 13.39 million rides. Ridership routinely stands at over 10 million on an average workday, accounting for 73% of trips on public transport in the city.

The Moscow Metro is a rapid transit system in the Moscow metropolitan area of Russia. It serves the capital city of Moscow and the neighbouring cities of Krasnogorsk, Reutov, Lyubertsy, and Kotelniki. Opened in 1935 with one 11-kilometre (6.8 mi) line and 13 stations, it was the first underground railway system in the Soviet Union.

As of December 2024, the Moscow Metro has 300 stations and 525.8 km (326.7 mi) of routes, making it the 8th-longest in the world, the longest in Europe and the longest outside China. It is also the only system in Russia with two circle lines. The system is mostly underground, with the deepest section 73 m (240 ft) underground at the Park Pobedy station, one of the world's deepest underground stations. It is the busiest metro system in Europe, the busiest in the world outside Asia, and is considered a tourist attraction in itself, thanks to its lavish interior decoration.
