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
784-450: 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
882-646: 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
980-565: 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
1078-405: 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

1862-558: 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
1960-492: A subway system for Shanghai dates back to the year 1950. Against the backdrop of the air raids of Shanghai by the retreating Nationalist forces in that year, a team of Soviet technical specialists visiting the city made a proposal to the Municipal Committee on Urban Planning and Design for a dual-purpose underground railway system, to be used for mass transit during peace times, and as shelter facility in times of war. It

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
2254-608: 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
2352-892: 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. 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
2450-506: 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
2548-740: Is cellular phone network coverage across the network. In 2020, all stations provided 5G network coverage. Free WiFi is also provided. There are toilets for passengers in more than 90% metro stations in Shanghai. The system is 100% wheelchair accessible, with elevators at all stations. Riders are subject to searches of their persons and belongings at all stations by security inspectors using metal detectors, X-ray machines. Items banned from public transportation such as "guns, ammunition, knives, explosives, flammable and radioactive materials, and toxic chemicals" are subject to confiscation. Stations are equipped with closed-circuit television. Police use it to arrest pickpockets caught on CCTV, for example. Smoking

By then, every location in the central area of Shanghai will be within 600 m (2,000 ft) of a subway station. Shanghai metro is connected with the metro system of Suzhou Rail Transit ; the Suzhou Rail Transit line 11 connects Shanghai Metro line 11 with Suzhou Rail Transit line 3 . There are currently over 7,000 railcars in
2940-548: 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

Some systems have been built from scratch, others are reclaimed from former commuter rail or suburban tramway systems that have been upgraded, and often supplemented with an underground or elevated downtown section. Ground-level alignments with
7056-418: The network map "readable" by illiterate people, this system has since become an "icon" of the system. Compared to other modes of transport, rapid transit has a good safety record, with few accidents. Rail transport is subject to strict safety regulations , with requirements for procedure and maintenance to minimize risk. Head-on collisions are rare due to use of double track, and low operating speeds reduce
7154-498: The next stop in Mandarin, English, and (on lines 16 and 17 only) Shanghainese , but the messages stating nearby attractions or shops for a given station (a form of paid advertising) are in Mandarin only. The metro operating company is resistant to expanding use of Shanghainese for announcing stops, on the basis that, on most lines, the majority of passengers can understand either Mandarin or English. The Metro authority has tested
7252-402: The next vehicle will arrive, and expected travel times. The standardized GTFS data format for transit information allows many third-party software developers to produce web and smartphone app programs which give passengers customized updates regarding specific transit lines and stations of interest. Mexico City Metro uses a unique pictogram for each station. Originally intended to help make
7350-949: 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
7448-588: The only two North American systems that are primarily called "subways". In most of Southeast Asia and in Taiwan , rapid transit systems are primarily known by the acronym MRT . The meaning varies from one country to another. In Indonesia , the acronym stands for Moda Raya Terpadu or Integrated Mass [Transit] Mode in English. In the Philippines , it stands for Metro Rail Transit . Two underground lines use
7546-418: The other carriages, the air-conditioning is adjustable for different carriages on these lines. The measure aims to address the needs of some passengers who find the trains "too cold," especially the elderly and children. Almost all stations have (full height) platform screen doors with sliding acrylic glass at the platform edge. Only half height doors called automatic platform gates are placed at most of
7644-582: The outset. Budapest , Chicago , Glasgow , Boston and New York City all converted or purpose-designed and built electric rail services. 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
7742-601: The platforms show passengers when the next two trains are coming, along with advertisements and public service announcements. The subway cars contain LCD screens showing advertisements and on some lines, the next stop, while above-ground trains have LED screens showing the next stop. The LED screens are being phased in on line 1 and are also included in lines 7 and 9 , two underground lines. Station signs are in Simplified Chinese and English. There are recorded messages stating
7840-908: 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
7938-642: The rapidly increasing demand for efficient urban public transit saw a swift resurrection of plans for a rapid rail transit system in Shanghai. In 1983, a jointly-published "Proposal on the Construction of a North-South Rapid Rail Transit Line" by the Municipal Planning Committee, the Municipal Construction Committee, in collaboration with the Municipal Bureaus of Urban Planning, of Public Infrastructure, of Railways and of Public Works, called for
8036-525: 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
8134-733: The station to reduce electricity usage. Shanghai metro started building solar plants from 2013 and the process has been accelerated since 2019, with plans to build rooftop solar plants with a total electricity generation capacity of 30 to 50 megawatts between 2021 and 2025. In 2021 it owned through it subsidiary Shanghai Metro New Energy Co., Ltd. ten rooftop solar plants on depots and parking lots (Chuanyanghe, Zhibei, Jinqiao, Longyang Road, Sanlin, Fujin Road, Zhongchun Road, Beizhai Road, Chentai Road and Pujiang Town) generating an average annual power generation of about 23 million kwh. Annual electricity consumption of Shanghai Metro exceeds 2.5 billion kWh. There
8232-462: The suburban rail transport network so that it can link to and coordinate with state rail lines, metro lines, and light railways. One or two rail transport lines are planned between every new city and the central city. In 2003 when the length was only 3 lines, 65 kilometers (with a further 5 lines already under construction), Shanghai was named host city for the World Expo 2010, plans were made to extend
8330-636: The suburbs, allowing a higher service frequency in the center. 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
8428-706: 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
8526-519: 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
8624-410: The time. In the early 2000s, before the screen doors were installed, the annual suicide rate on the Shanghai subway system averaged about eight. In 2003 Shanghai Metro Operation Technology Development Co., Ltd. developed domestically platform screen doors with costs only 40% of imported platform screen doors (they cost over RMB6 million each to install). Shanghai Circus World , opened December 28, 2004,
8722-503: The train if needed and handles emergencies. The exceptions being: Most lines currently use 6 car sets, with the exceptions being: On most lines the maximum operating speed is 80 km/h (50 mph), with the exceptions being: Pujiang line is the only line using cars with rubber tires running on concrete tracks. All subway cars have air-conditioning. During summer of 2021 the subway's first and last carriages on Metro lines 3-5, 10-13, and 15-18 will be 2 degrees Celsius warmer than
8820-511: 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 the same public transport authorities . Some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. 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
8918-591: 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
9016-540: 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
9114-400: Was approved by the State Council of China on May 11, 2001. The plan had 17 lines in total, containing four intra-city-region express rail lines, eight urban metro lines, and five urban light-rail lines with a total length of about 780 kilometers. The total length of the planned MRT network in the central city will add up to 488 kilometers. In addition, Shanghai will strengthen the development of
9212-696: Was carried out in strict confidentiality. In August 1964, the Tunnel Engineering section of the Municipal Urban Construction Bureau completed the route selection phase for the north-south line (later Line 1 ), which was eventually to connect key locations in the downtown core, including the Shanghai Cultural Square, People's Square and the then Shanghai North railway station , with the rapidly industrializing and urbanizing northern districts of Zhabei and Baoshan , including
9310-845: 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) 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
9408-443: Was later, in 1953, during confidential consultations held with Soviet urban planning specialists by Li Gancheng, the then-Deputy Chief and Party Secretary of the Municipal Construction Committee in Shanghai, that the initial concepts of a north-south line and an east-west line were pencilled on a map of the city, which would later become Line 1 and Line 2 . Further consultations and public surveys on transit needs were held in 1959 by
9506-681: 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
9604-460: Was the first station to have installed platform screen doors. To help cope with passenger handling, platform safety doors were built for line 4 onwards and a program for retrofitting older lines was put in place. The retrofitting on existing lines started in November 2005 with line 1 (first station was Xujiahui ) whose core stations had doors by the end of 2006. Originally, platform screen doors were adopted to prevent cool or hot air from leaving
