List Of Metro Systems
This list of metro systems includes electrified rapid transit train systems worldwide. In some parts of the world, metro systems are referred to as subways, U-Bahn or undergrounds. , 205 cities in 61 countries have a metro system. The London Underground first opened as an underground railway in 1863 and its first electrified underground line opened in 1890, making it the world's oldest metro system. The New York City Subway has the greatest number of stations with 472. The country with the most metro systems is China, with 46 in operation. The Shanghai Metro is the world's longest metro network at and also has the highest annual ridership at 2.83 billion trips. Considerations The International Association of Public Transport (L'Union Internationale des Transports Publics, or UITP) defines metro systems as urban passenger transport systems, "operated on their own right of way and segregated from general road and pedestrian traffic". The terms heavy rail (mainly in North A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shanghai Metro
The Shanghai Metro (; Shanghainese: ''Zaon6he5 Di6thiq7'') is a rapid transit system in Shanghai, operating urban and suburban transit services to 14 of its 16 municipal districts and to Kunshan, Jiangsu Province. Served as a part of Shanghai rail transit, the Shanghai Metro system is the world's biggest metro system by route length, totaling . It is also the second biggest by the number of stations with 396 stations on 19 lines. It ranks first in the world by annual ridership with 3.88 billion rides delivered in 2019. The daily ridership record was set at 13.29 million on March 8, 2019. Over 10 million people use the system on an average workday. History A subway was first proposed for Shanghai in 1956. Tests started in 1964, but construction was suspended during the Cultural Revolution in the mid-1960s. Opening in 1993 with full-scale construction extending back to 1986, the Shanghai Metro is the third-oldest rapid transit system in mainland China, after the Beijing ...

Commuter Rail
Commuter rail, or suburban rail, is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Generally commuter rail systems are considered heavy rail, using electrified or diesel trains. Distance charges or zone pricing may be used. The term can refer to systems with a wide variety of different features and service frequencies, but is often used in contrast to rapid transit or light rail. Similar non-English terms include ''Treno suburbano'' in Italian, ''Cercanías'' in Spanish, Aldiriak in Basque, Rodalia in Catalan/Valencian, Proximidades in Galician, ''Proastiakos'' in Greek, ''Train de banlieue'' in French, '' Banliyö treni '' in Turkish, ''Příměstský vlak'' or ''Esko'' in Czech, ''Elektrichka'' in Russian, ''Pociąg podmiejski '' in Polish and ''Pendeltåg'' in Swedish. Some services share similarities with both commuter rail and high-frequency rapid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Metro Systems
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as #Monism and pluralism, one simple object while others analyze the world as a complex made up of many parts. In ''#Scientific cosmology, scientific cosmology'' the world or universe is commonly defined as "[t]he totality of all space and time; all that is, has been, and will be". ''#Theories of modality, Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''#Phenomenology, Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''#Philosophy of mind, philosop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Rail Transit
Urban rail transit is an all-encompassing term for various types of local rail systems providing passenger service within and around urban or suburban areas. The set of urban rail systems can be roughly subdivided into the following categories, which sometimes overlap because some systems or lines have aspects of multiple types. Types Tram A ''tram'', ''streetcar'', or ''trolley'' system is a rail-based transit system that runs mainly or completely along streets (with street running), with a relatively-low capacity and frequent stops. Passengers usually board at the street or curb level, but low-floor trams may allow level boarding. Longer-distance lines are called ''interurbans'' or ''radial railways''. Few interurbans remain, most having been upgraded to commuter rail or light rail or abandoned. The term "tram" is used in most parts of the world. In North America, such systems are referred to as "streetcar" or "trolley" systems. In Germany, such systems are called "Straße ...

People Mover
A people mover or automated people mover (APM) is a type of small scale automated guideway transit system. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks. The term was originally applied to three different systems, developed roughly at the same time. One was Skybus, an automated mass transit system prototyped by the Westinghouse Electric Corporation beginning in 1964. The second, alternately called the People Mover and Minirail, opened in Montreal at Expo 67. Finally the last, called PeopleMover or WEDway PeopleMover, was an attraction that was originally presented by Goodyear Tire and Rubber Company and that opened at Disneyland in 1967. Now, however, the term "people mover" is generic, and may use technologies such as monorail, rail tracks or maglev. Propulsion may involve conventional on-board electric motors, linear motors or cable traction. Generally speaking, larger APMs are refe ...

Funicular
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys tha ...

S-Bahn
The S-Bahn is the name of hybrid urban- suburban rail systems serving a metropolitan region in German-speaking countries. Some of the larger S-Bahn systems provide service similar to rapid transit systems, while smaller ones often resemble commuter or even regional rail. The term derives from ''Schnellbahn'', ''Stadtbahn'' or ''Stadtschnellbahn''. Similar systems in Switzerland are known as S-Bahn as well. In Belgium it is known as S-Trein (Flemish) or Train S (French). In Belgium there are S-Trains in the five largest cities: Brussels, Antwerp, Liège, Ghent and Charleroi. In Denmark, they are known as S-tog , in the Czech Republic as Esko or S-lines. Characteristics There is no complete definition of an S-Bahn system. S-Bahn are, where they exist, the most local type of railway stopping at all existing stations inside and around a city, while other mainline trains only call at major stations. They are slower than mainline railways but usually serve as fast crosstown se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Metro
A medium-capacity system (MCS), also known as light rapid transit or light metro, is a rail transport system with a capacity greater than light rail, but less than typical heavy-rail rapid transit. MCS’s trains are usually 1-4 cars, or 1 light rail vehicle (LRV). Most medium-capacity rail systems are automated or use light rail type vehicles. Light rail is considered high capacity as trains use 2-4 LRVs. Since ridership determines the scale of a rapid transit system, statistical modeling allows planners to size the rail system for the needs of the area. When the predicted ridership falls between the service requirements of a light rail and heavy rail or metro system, an MCS project is indicated. An MCS may also result when a rapid transit service fails to achieve the requisite ridership due to network inadequacies (e.g. single-tracking) or changing demographics. In contrast with most light rail systems, an MCS usually runs on a fully grade separated exclusive right-of-way. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

Rubber-tyred Metro
A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road and rail technology. The vehicles have wheels with rubber tires that run on rolling pads inside guide bars for traction, as well as traditional railway steel wheels with deep flanges on steel tracks for guidance through conventional switches as well as guidance in case a tyre fails. Most rubber-tyred trains are purpose-built and designed for the system on which they operate. Guided buses are sometimes referred to as 'trams on tyres', and compared to rubber-tyred metros. History The first idea for rubber-tyred railway vehicles was the work of Scotsman Robert William Thomson, the original inventor of the pneumatic tyre. In his patent of 1846 he describes his 'Aerial Wheels' as being equally suitable for, "the ground or rail or track on which they run". The patent also included a drawing of such a railway, with the weight carried by pneumatic main wheels running on a flat board t ...

Inter-city Rail
Inter-city rail services are express passenger train services that run services that connect cities over longer distances than commuter or regional trains. There is no precise definition of inter-city rail; its meaning may vary from country to country. Most broadly, it can include any rail services that are neither short-distance commuter rail trains within one city area, nor slow regional rail trains calling at all stations and covering local journeys only. Most typically, an inter-city train is an express train with limited stops and comfortable carriages to serve long-distance travel. Inter-city rail sometimes provides international services. This is most prevalent in Europe, due to the close proximity of its 50 countries in a 10,180,000 square kilometre (3,930,000 sq mi) area. Eurostar and EuroCity are examples of this. In many European countries the word "InterCity" or "Inter-City" is an official brand name for a network of regular-interval, relatively long-distance ...
