92-403: Abu Dhabi Metro is a planned metro system that would be part of a larger transit network for the city of Abu Dhabi , United Arab Emirates . First announced in 2008, as of 2024 construction has yet to start. The entire transit network will be 131 km long when complete, including an 18-kilometre (11 mi) partially underground metro line, two light rail lines and bus rapid transit. It

184-527: A central business district located away from its traditional city center, and there may be multiple CBDs within a single urban area. The CBD will often be highly accessible and have a large variety and concentration of specialised goods and services compared to other parts of the city. Midtown Manhattan is the largest central business district in New York City and in the United States. In Chicago ,

276-425: 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

368-450: 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

460-646: 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

552-565: 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

644-405: 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

The New World grew quickly after the emergence of modern transport, therefore a single centre often included many of the region's tallest buildings and served as both a commercial and cultural city centre. In the 21st century, increasing urbanisation has led to the development of megacities that often have multiple CBDs scattered across

2392-548: 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

2484-412: Is serviced by at least one specific route with trains stopping at all or some of the line's stations. Most systems operate several routes, and distinguish them by colors, names, numbering, or a combination thereof.

In the Philippines , it stands for Metro Rail Transit . Two underground lines use

6992-510: The other two business districts, Yeouido has some of Seoul's tallest skyscrapers, including Parc1 Tower , International Finance Center Seoul , and the 63 Building . Yeouido is where the National Assembly of South Korea and many media companies and political institutions are based. Smaller but notable central business districts in South Korea include the Jamsil area, which is the location of

7084-582: 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

7176-408: The project were due to submit statements of intent to the government by mid June 2013. The Department of Transport has planned phase 1 for construction in three contracts: Contracts are due to be awarded in 2015. Under the original plan, the first phase was due to be complete by 2015, but is now scheduled to be operational no sooner than 2030. From October 2016, the project halted. In August 2018,

7268-908: 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

7360-469: The reunification with the redevelopment of Potsdamer Platz , and the construction of numerous shopping centers, government ministries, embassies, office buildings and entertainment venues, was the area revived. In Frankfurt am Main 's city center, there is a business district called the " Bankenviertel ". In Düsseldorf , there is a business district which is located around the famous high street Königsallee with banks, shops and offices. Traditionally,

7452-525: 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

7544-530: The site of the rail terminus for the Kuala Lumpur–Singapore High Speed Rail . South Africa 's largest cities, Cape Town , Durban , Johannesburg , Pretoria , and Port Elizabeth , have CBDs that include the corporate headquarters for many of South Africa's largest companies, its convention centers , and many of the country's tallest buildings. Cape Town has one of South Africa's most iconic skyline (which includes Table Mountain ) and

7636-636: 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

7728-706: 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

7820-463: 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

7912-511: 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

8004-594: The urban area. Downtown sections of cities, especially in North America , often are distinct from CBDs and city centres. No two CBDs have the same spatial shape, but there are certain common geometric patterns, which are largely a result of centralised commercial and industrial activities. In Australia , the term CBD is widely used officially and colloquially, in the sense of city centre. The two biggest cities, Melbourne and Sydney , have large CBDs. Sydney features growing micro central business districts, which serve as

8096-591: 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

8188-593: The years, Bogotá has developed minor business districts, which include Avenida Chile , Ciudad Salitre , with companies like Avianca , Rappi , Johnson & Johnson , Terpel , Hilton , Hyatt , Marriott , Sheraton , Ramada , City Express , Aloft and Novotel ; or Complejo Santa Bárbara , the last of which features the only W Hotel in the city. Colombia's other notable CBDs include Parque Berrío in Medellín , Bocagrande in Cartagena (the largest touristic CBD in

8280-540: 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

8372-845: 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

8464-681: 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
