Rapid transit or mass rapid transit ( MRT ) or heavy rail , commonly referred to as metro , is a type of high-capacity public transport that is generally built in urban areas . A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway , tube , metro or underground . They are sometimes grade-separated on elevated railways , in which case some are referred to as el trains – short for "elevated" – or skytrains . Rapid transit systems are railways , usually electric , that unlike buses or trams operate on an exclusive right-of-way , which cannot be accessed by pedestrians or other vehicles.
79-526: The Osaka Metro ( 大阪メトロ , Ōsaka Metoro ) is a major rapid transit system in the Osaka metropolitan area of Japan , operated by the Osaka Metro Company, Ltd . It serves the city of Osaka and the adjacent municipalities of Higashiosaka , Kadoma , Moriguchi , Sakai , Suita , and Yao . Osaka Metro forms an integral part of the extensive mass transit system of Greater Osaka (part of
158-425: A body of water), which are potential congestion sites but also offer an opportunity for transfers between lines. Ring lines provide good coverage, connect between the radial lines and serve tangential trips that would otherwise need to cross the typically congested core of the network. A rough grid pattern can offer a wide variety of routes while still maintaining reasonable speed and frequency of service. A study of

As of 2021 , China has the largest number of rapid transit systems in the world – 40 in number, running on over 4,500 km (2,800 mi) of track – and was responsible for most of the world's rapid-transit expansion in the 2010s. The world's longest single-operator rapid transit system by route length
316-438: A city’s name can help establish its identity and foster community pride. Such word marks can reflect a city’s character, culture, and history, making it more recognizable to residents and visitors. They can be utilized in various contexts, such as on signage, promotional materials, or public spaces, contributing to a cohesive urban identity. Overall, word marks for cities provide a straightforward way to enhance visibility and create
395-454: A code for its stations. Unlike that of Singapore's MRT, it is mostly numbers. Based on the line number, for example Sinyongsan station, is coded as station 429. Being on Line 4, the first number of the station code is 4. The last two numbers are the station number on that line. Interchange stations can have multiple codes. Like City Hall station in Seoul which is served by Line 1 and Line 2. It has
474-651: A code of 132 and 201 respectively. The Line 2 is a circle line and the first stop is City Hall, therefore, City Hall has the station code of 201. For lines without a number like Bundang line it will have an alphanumeric code. Lines without a number that are operated by KORAIL will start with the letter 'K'. With widespread use of the Internet and cell phones globally, transit operators now use these technologies to present information to their users. In addition to online maps and timetables, some transit operators now offer real-time information which allows passengers to know when
553-512: A connection to the subway network's roots. When it was run by the Osaka Municipal Transportation Bureau , the subway used a logo known as the “Circle-Ko” ( マルコ , Maru-Ko ) symbol, which is a katakana “ko” ( コ ) for “Urban rail transit” ( 高速鉄道 , kōsoku tetsudō ) superimposed over a circular capital “O” for “Osaka” (see infobox, above). This remained on many older trainsets and at stations, until it
632-583: A conventional track is often provided in case of flat tires and for switching . There are also some rubber-tired systems that use a central guide rail , such as the Sapporo Municipal Subway and the NeoVal system in Rennes , France. Advocates of this system note that it is much quieter than conventional steel-wheeled trains, and allows for greater inclines given the increased traction of
711-405: A dedicated right-of-way are typically used only outside dense areas, since they create a physical barrier in the urban fabric that hinders the flow of people and vehicles across their path and have a larger physical footprint. This method of construction is the cheapest as long as land values are low. It is often used for new systems in areas that are planned to fill up with buildings after the line
790-582: A full-fledged metro system. The network's first service, the Midōsuji Line from Umeda to Shinsaibashi , opened in 1933. As a north–south trunk route , it is the oldest and busiest line in the whole network. Both it and the main east–west route, the Chūō Line , were later extended to the north and east, respectively. These extensions are owned by other railway companies, but both Osaka Metro and these private operators run their own set of trains through between
869-418: A large number of factors, including geographical barriers, existing or expected travel patterns, construction costs, politics, and historical constraints. A transit system is expected to serve an area of land with a set of lines , which consist of shapes summarized as "I", "L", "U", "S", and "O" shapes or loops. Geographical barriers may cause chokepoints where transit lines must converge (for example, to cross

The terms Underground and Tube are used for the London Underground . The North East England Tyne and Wear Metro , mostly overground, is known as the Metro . In Scotland , the Glasgow Subway underground rapid transit system is known as the Subway . In Ireland ,
1027-564: A lettermark logo) is a type of logo, not a type of wordmark, which consists of just text set in a particular style, such as a typeface or color, without other graphical features. For example, the SONY logo contains only the name in uppercase, set in a particular typeface. In some cases, such as Disney's logo, a custom or proprietary typeface is used. Word marks can function effectively as identifiers for cities, similar to their use for brands and companies. A unique typographic representation of
1106-452: A line is obtained by multiplying the car capacity, the train length, and the service frequency . Heavy rapid transit trains might have six to twelve cars, while lighter systems may use four or fewer. Cars have a capacity of 100 to 150 passengers, varying with the seated to standing ratio – more standing gives higher capacity. The minimum time interval between trains is shorter for rapid transit than for mainline railways owing to
1185-615: A metro. In Spain, such systems are present in Madrid , Barcelona , Bilbao and Valencia . In Portugal, Lisbon has a metro. The Italian cities of Catania , Genoa , Milan , Naples , Rome and Turin also have metro lines. In Germany and Austria they rapid transit is known as U-Bahn , which are often supported by S-Bahn systems. In Germany, U-Bahn systems exist in Berlin , Hamburg , Munich and Nuremberg , while in Austria such
1264-512: A public-facing name (e.g. “Midōsuji Line” for Rapid Electric Tramway Line No. 1) and a specific color, as well as a single Latin letter, which is paired with a different number at each station for easy identification (see below). Icons for each line (featured in station wayfinding signage) are represented by a solid roundel in the line color, superimposed with the line's letter-designation in the Parisine typeface. An older branding (also used on
1343-418: A rapid transit setting. Wordmark A wordmark or word mark is a text-only statement of the name of a product, service, company, organization, or institution which is used for purposes of identification and branding. A wordmark can be an actual word (e.g., Apple), a made-up term that reads like a word (e.g., iPhone), or an acronym, initialism, or series of letters (e.g., IBM). In some jurisdictions
1422-565: A specialized transit police may be established. These security measures are normally integrated with measures to protect revenue by checking that passengers are not travelling without paying. Some subway systems, such as the Beijing Subway , which is ranked by Worldwide Rapid Transit Data as the "World's Safest Rapid Transit Network" in 2015, incorporates airport-style security checkpoints at every station. Rapid transit systems have been subject to terrorism with many casualties, such as
1501-608: A system exists in Vienna . In addition, the small, car-free town of Serfaus in the Austrian state of Tyrol also features a short U-Bahn line. There are no U-Bahn systems in the German-speaking part of Switzerland, but the city of Lausanne has its own, small metro system. In Zurich, Switzerland's largest city, a project for a U-Bahn network was stopped by a referendum in the 1970s and instead its S-Bahn system
1580-565: A total of 495 buildings. [REDACTED] Rapid transit system Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on railway tracks . Some systems use guided rubber tires , magnetic levitation ( maglev ), or monorail . The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by

In many jurisdictions , such as the United States and European Union , a qualifying wordmark may be registered as a trademark , making it a protected intellectual property . Unlike names and logos , trademarked wordmarks are generally not case-sensitive and are listed in uppercase by trademark registrars such as
1817-801: Is a shortened reference to a metropolitan area . Rapid transit systems such as the Washington Metrorail , Los Angeles Metro Rail , the Miami Metrorail , and the Montreal Metro are generally called the Metro . In Philadelphia , the term "El" is used for the Market–Frankford Line which runs mostly on an elevated track, while the term "subway" applies to the Broad Street Line which is almost entirely underground. Chicago 's commuter rail system that serves
1896-608: Is a single corporate image for the entire transit authority, but the rapid transit uses its own logo that fits into the profile. A transit map is a topological map or schematic diagram used to show the routes and stations in a public transport system. The main components are color-coded lines to indicate each line or service, with named icons to indicate stations. Maps may show only rapid transit or also include other modes of public transport. Transit maps can be found in transit vehicles, on platforms , elsewhere in stations, and in printed timetables . Maps help users understand
1975-506: Is built. Most rapid transit trains are electric multiple units with lengths from three to over ten cars. Crew sizes have decreased throughout history, with some modern systems now running completely unstaffed trains. Other trains continue to have drivers, even if their only role in normal operation is to open and close the doors of the trains at stations. Power is commonly delivered by a third rail or by overhead wires . The whole London Underground network uses fourth rail and others use
2054-543: Is heard in bilingual Japanese-English automated next-station announcements on board all trains, which also provide information on local businesses near the station. Only Hankyu stations served by the Sakaisuji Line do not follow this convention. The network is operated by a municipally owned stock company trading as the Osaka Metro Company, Ltd. The Osaka Metro Co. is the direct legal successor to
2133-416: Is necessary, rolling stock with a smaller loading gauge from one sub network may be transported along other lines that use larger trains. On some networks such operations are part of normal services. Most rapid transit systems use conventional standard gauge railway track . Since tracks in subway tunnels are not exposed to rain , snow , or other forms of precipitation , they are often fixed directly to
2212-555: Is referred to simply as "the subway", despite 40% of the system running above ground. The term "L" or "El" is not used for elevated lines in general as the lines in the system are already designated with letters and numbers. The "L" train or L (New York City Subway service) refers specifically to the 14th Street–Canarsie Local line, and not other elevated trains. Similarly, the Toronto Subway is referred to as "the subway", with some of its system also running above ground. These are

Most systems operate several routes, and distinguish them by colors, names, numbering, or a combination thereof. Some lines may share track with each other for a portion of their route or operate solely on their own right-of-way. Often a line running through the city center forks into two or more branches in

In 2010, the greater Osaka region had 13 million rail passengers daily (see Transport in Keihanshin ) of which the Osaka Municipal Subway (as it was then known) accounted for 2.29 million. Osaka Metro is the only subway system in Japan to be partially legally classified as a tram system, whereas all other subway systems in Japan are legally classified as railways . Despite this, it has characteristics typical of
2765-740: The Metropolitan Railway opened publicly in London in 1863. High capacity monorails with larger and longer trains can be classified as rapid transit systems. Such monorail systems recently started operating in Chongqing and São Paulo . Light metro is a subclass of rapid transit that has the speed and grade separation of a "full metro" but is designed for smaller passenger numbers. It often has smaller loading gauges, lighter train cars and smaller consists of typically two to four cars. Light metros are typically used as feeder lines into
2844-578: The Montreal Metro (opened 1966) and Sapporo Municipal Subway (opened 1971), their entirely enclosed nature due to their use of rubber-tyred technology to cope with heavy snowfall experienced by both cities in winter precludes any air-conditioning retrofits of rolling stock due to the risk of heating the tunnels to temperatures that would be too hot for passengers and for train operations. In many cities, metro networks consist of lines operating different sizes and types of vehicles. Although these sub-networks may not often be connected by track, in cases when it

3318-450: The deep tube lines . Historically, rapid transit trains used ceiling fans and openable windows to provide fresh air and piston-effect wind cooling to riders. From the 1950s to the 1990s (and in most of Europe until the 2000s), many rapid transit trains from that era were also fitted with forced-air ventilation systems in carriage ceiling units for passenger comfort. Early rapid transit rolling stock fitted with air conditioning , such as

Some urban rail lines are built to a loading gauge as large as that of main-line railways ; others are built to a smaller one and have tunnels that restrict the size and sometimes the shape of the train compartments. One example is most of the London Underground , which has acquired the informal term "tube train" due to the cylindrical shape of the trains used on

Nearly all stations have a letter number combination , the letter identifying the line served by the station and the number indicating the relative location of the station on the line. For example, Higobashi Station on the Yotsubashi Line is also known as Y12. This combination

Also unusually, all lines use standard gauge ; there are no narrow gauge sections of track due to the network being almost entirely self-enclosed (although Kyoto and Kobe also have entirely standard gauge metros with through services to private railways). Osaka Metro charges five types of fares for single rides, based on

Also, unlike most other rapid transit networks in Japan (but like the preceding Tokyo Metro Ginza Line [the only rapid transit line in Asia at the time], and the subsequent Marunouchi line , the early lines in Nagoya and the Blue line in Yokohama), most Osaka subway lines use a third rail electrification system for trains. Only three lines use overhead catenary :

#17327718149814108-478: The beginning of rapid transit. Initial experiences with steam engines, despite ventilation, were unpleasant. Experiments with pneumatic railways failed in their extended adoption by cities. In 1890, the City & South London Railway was the first electric-traction rapid transit railway, which was also fully underground. Prior to opening, the line was to be called the "City and South London Subway", thus introducing
4187-414: The display of the transit network. Often this has the effect of compressing the distance between stations in the outer area of the system, and expanding distances between those close to the center. Some systems assign unique alphanumeric codes to each of their stations to help commuters identify them, which briefly encodes information about the line it is on, and its position on the line. For example, on

On April 8, 1970, a gas explosion occurred during an expansion of the Tanimachi Line at Tenjimbashisuji Rokuchōme Station , killing 79 people and injuring 420. The gas leaked out from a detached joint and filled the tunnel and exploded when a service vehicle's engine sparked over leaking gas, creating a fire column over 10 metres (33 ft) tall that burned around 30 buildings and damaged or destroyed

Boston's subway system is known locally as "The T". In Atlanta , the Metropolitan Atlanta Rapid Transit Authority goes by the acronym "MARTA." In the San Francisco Bay Area , residents refer to Bay Area Rapid Transit by its acronym "BART". The New York City Subway

For elevated lines, another alternative is the monorail , which can be built either as straddle-beam monorails or as a suspended monorail . While monorails have never gained wide acceptance outside Japan, there are some such as Chongqing Rail Transit 's monorail lines which are widely used in

Mexico City Metro uses a unique pictogram for each station. Originally intended to help make
4977-958: The occurrence and severity of rear-end collisions and derailments . Fire is more of a danger underground, such as the King's Cross fire in London in November 1987, which killed 31 people. Systems are generally built to allow evacuation of trains at many places throughout the system. High platforms , usually over 1 meter / 3 feet, are a safety risk, as people falling onto the tracks have trouble climbing back. Platform screen doors are used on some systems to eliminate this danger. Rapid transit facilities are public spaces and may suffer from security problems: petty crimes , such as pickpocketing and baggage theft, and more serious violent crimes , as well as sexual assaults on tightly packed trains and platforms. Security measures include video surveillance , security guards , and conductors . In some countries

Advancements in technology have allowed new automated services. Hybrid solutions have also evolved, such as tram-train and premetro , which incorporate some of the features of rapid transit systems. In response to cost, engineering considerations and topological challenges some cities have opted to construct tram systems, particularly those in Australia, where density in cities
5293-908: The rapid transit system varies greatly between cities, with several transport strategies. Some systems may extend only to the limits of the inner city, or to its inner ring of suburbs with trains making frequent station stops. The outer suburbs may then be reached by a separate commuter rail network where more widely spaced stations allow higher speeds. In some cases the differences between urban rapid transit and suburban systems are not clear. Rapid transit systems may be supplemented by other systems such as trolleybuses , regular buses , trams , or commuter rail. This combination of transit modes serves to offset certain limitations of rapid transit such as limited stops and long walking distances between outside access points. Bus or tram feeder systems transport people to rapid transit stops. Each rapid transit system consists of one or more lines , or circuits. Each line
5372-401: The rubber tires. However, they have higher maintenance costs and are less energy efficient. They also lose traction when weather conditions are wet or icy, preventing above-ground use of the Montréal Metro and limiting it on the Sapporo Municipal Subway, but not rubber-tired systems in other cities. Some cities with steep hills incorporate mountain railway technologies in their metros. One of

The world's first rapid transit system was the partially underground Metropolitan Railway which opened in 1863 using steam locomotives , and now forms part of the London Underground . In 1868, New York opened the elevated West Side and Yonkers Patent Railway , initially

This arrangement is used by many systems, such as the Copenhagen Metro , the Milan Metro , the Oslo Metro , the Istanbul Metro and the New York City Subway . Alternatively, there may be a single central terminal (often shared with the central railway station), or multiple interchange stations between lines in the city center, for instance in
5609-646: The term subway . In Thailand , it stands for Metropolitan Rapid Transit , previously using the Mass Rapid Transit name. Outside of Southeast Asia, Kaohsiung and Taoyuan, Taiwan , have their own MRT systems which stands for Mass Rapid Transit , as with Singapore and Malaysia . In general rapid transit is a synonym for "metro" type transit, though sometimes rapid transit is defined to include "metro", commuter trains and grade separated light rail . Also high-capacity bus-based transit systems can have features similar to "metro" systems. The opening of London's steam-hauled Metropolitan Railway in 1863 marked
5688-467: The term Subway into railway terminology. Both railways, alongside others, were eventually merged into London Underground . The 1893 Liverpool Overhead Railway was designed to use electric traction from the outset. The technology quickly spread to other cities in Europe , the United States, Argentina, and Canada, with some railways being converted from steam and others being designed to be electric from
5767-543: The two sections . All but one of the remaining lines of the network, including the Yotsubashi Line , Tanimachi Line , and Sennichimae Line , are completely independent lines with no through services. The lone exception is the Sakaisuji Line , which operates through trains to existing Hankyu Railway lines and is the only line to operate through services to existing railway lines that are not isolated from
5846-601: The use of communications-based train control : the minimum headway can reach 90 seconds, but many systems typically use 120 seconds to allow for recovery from delays. Typical capacity lines allow 1,200 people per train, giving 36,000 passengers per hour per direction . However, much higher capacities are attained in East Asia with ranges of 75,000 to 85,000 people per hour achieved by MTR Corporation 's urban lines in Hong Kong. Rapid transit topologies are determined by
5925-559: Was Singapore's Mass Rapid Transit (MRT) system, which launched its first underground mobile phone network using AMPS in 1989. Many metro systems, such as the Hong Kong Mass Transit Railway (MTR) and the Berlin U-Bahn, provide mobile data connections in their tunnels for various network operators. The technology used for public, mass rapid transit has undergone significant changes in the years since
6004-756: Was built, but the current state of the artificial island (with only industrial facilities and a single convenience store for the workers) meant it would have been unlikely to proceed had Osaka not won the bid. Osaka Municipal Subway rolling stock use two types of propulsion systems . The vast majority of lines use trains with conventional electric motors , but the two newest lines, the Nagahori Tsurumi-ryokuchi Line and Imazatosuji Line , use linear motor -powered trains, which allow them to use smaller trains and tunnels, reducing construction costs. These two lines have half-height automatic platform gates installed at all station platforms, as does
6083-476: Was completely replaced by the Osaka Metro logo by 2020. Currently, there are eight lines, operating on 129.9 kilometers (80.7 mi) of track and serving 123 stations; there is also a 7.9-kilometer (4.9 mi)-long, 10-station automated people mover line known as the "New Tram". Length In addition, there are five line extensions and one entirely new line that are planned. However, on August 28, 2014,
6162-899: Was developed further. Other Central European countries also have metro lines, for example in the cities of Budapest (Hungary), Prague (Czech Republic) and Warsaw (Poland). In Eastern Europe , metro systems are in operation in Minsk (Belarus), Kyiv (Ukraine), Riga (Latvia), Vilnius (Lithuania) and Moscow (Russia). In Southeastern European countries, there are metro systems in Athens and Thessaloniki (Greece), Belgrade (Serbia), Sofia (Bulgaria) and Istanbul (Turkey). In Northern Europe , rapid transit systems exist in Copenhagen (Denmark), Oslo (Norway), Stockholm (Sweden) and Helsinki (Finland). Various terms are used for rapid transit systems around North America . The term metro
6241-702: Was low and suburbs tended to spread out . Since the 1970s, the viability of underground train systems in Australian cities, particularly Sydney and Melbourne , has been reconsidered and proposed as a solution to over-capacity. Melbourne had tunnels and stations developed in the 1970s and opened in 1980. The first line of the Sydney Metro was opened in 2019. Since the 1960s, many new systems have been introduced in Europe , Asia and Latin America . In
