70-890: Dongguan Rail Transit or Dongguan Metro is the rapid transit system of the city of Dongguan in Guangdong Province of China . It is operated by the state-owned Dongguan Rail Transit Corporation. The construction of the first section of Line 2 began on 26 March 2010, opening on 27 May 2016. Current plans call for some lines of the Dongguan Rail Transit to connect with the neighbouring Shenzhen Metro and Guangzhou Metro . The first section (15 stations and 37.743 km long) of Line 2 from Dongguan railway station in Shilong Town to Humen railway station in Humen Town opened on 27 May 2016. The line

140-425: 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

210-454: 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

280-651: 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

350-583: 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

420-405: 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

490-418: 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

560-652: A large part of the network, for example, in outer suburbs, runs at ground level. In most of Britain , a subway is a pedestrian underpass . 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 ,

630-452: 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

700-615: 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

770-655: A rapid transit setting. Humen Town Humen Town ( simplified Chinese : 虎门镇 ; traditional Chinese : 虎門鎮 ; pinyin : Hǔmén zhèn ; Jyutping : Fu mun zan ), formerly Fumun , is a town in Dongguan city on the eastern side of the Humen strait on the Pearl River Delta , in Guangdong province, China. The former town of Taiping was incorporated into Humen Town in 1985. The population

840-565: 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

910-608: 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

980-667: Is a first-class port open to foreign vessels. Several Qing dynasty forts, including: Humen is located at the eastern end of the Humen Pearl River Bridge . Humen is served by regular direct buses traveling south from Guangzhou . Routes continue south by bus to Shenzhen's Window of the World theme park, from where it is possible to continue on to the Hong Kong border by bus or the Shenzhen Metro . There

1050-801: 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

1120-608: 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

1190-506: 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

1260-416: 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

1330-555: 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

1400-412: 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. 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

1470-612: Is supplying 6-car CIVAS metro trains for Dongguan. The first trains were built in Västerås , Sweden with the final assembly in Changzhou . [REDACTED] Rapid transit 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

1540-748: Is the most commonly used term for underground rapid transit systems used by non-native English speakers. Rapid transit systems may be named after the medium by which passengers travel in busy central business districts ; the use of tunnels inspires names such as subway , underground , Untergrundbahn ( U-Bahn ) in German, or the Tunnelbana (T-bana) in Swedish. The use of viaducts inspires names such as elevated ( L or el ), skytrain , overhead , overground or Hochbahn in German. One of these terms may apply to an entire system, even if

1610-627: The Dublin Area Rapid Transit is despite the name considered a commuter rail due to usage of mainline railways. In France, large cities, such as Paris , Marseille and Lyon , feature a Métro . Also the smaller cities of Lille Rennes have a light metro. Furthermore, Brussels in Belgium, and Amsterdam and Rotterdam in the Netherlands have metro systems in place. Several Southern European contries also have

1680-752: The Hudson and Manhattan Railroad K-series cars from 1958, the New York City Subway R38 and R42 cars from the late-1960s, and the Nagoya Municipal Subway 3000 series , Osaka Municipal Subway 10 series and MTR M-Train EMUs from the 1970s, were generally only made possible largely due to the relatively generous loading gauges of these systems and also adequate open-air sections to dissipate hot air from these air conditioning units. Especially in some rapid transit systems such as

1750-429: The London Underground . In 1868, New York opened the elevated West Side and Yonkers Patent Railway , initially a cable-hauled line using stationary steam engines . 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

1820-740: 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

1890-578: 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

1960-589: The Prague Metro . The London Underground and Paris Métro are densely built systems with a matrix of crisscrossing lines throughout the cities. The Chicago 'L' has most of its lines converging on The Loop , the main business, financial, and cultural area. Some systems have a circular line around the city center connecting to radially arranged outward lines, such as the Moscow Metro 's Koltsevaya Line and Beijing Subway 's Line 10 . The capacity of

2030-685: The Singapore MRT , Changi Airport MRT station has the alphanumeric code CG2, indicating its position as the 2nd station on the Changi Airport branch of the East West Line. Interchange stations have at least two codes, for example, Raffles Place MRT station has two codes, NS26 and EW14, the 26th station on the North South Line and the 14th station on the East West Line. The Seoul Metro is another example that utilizes

2100-450: 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

2170-409: The linear motor for propulsion. 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

2240-432: The 15 world largest subway systems suggested a universal shape composed of a dense core with branches radiating from it. Rapid transit operators have often built up strong brands , often focused on easy recognition – to allow quick identification even in the vast array of signage found in large cities – combined with the desire to communicate speed, safety, and authority. In many cities, there

2310-488: The 1995 Tokyo subway sarin gas attack and the 2005 " 7/7 " terrorist bombings on the London Underground. Some rapid transport trains have extra features such as wall sockets, cellular reception, typically using a leaky feeder in tunnels and DAS antennas in stations, as well as Wi-Fi connectivity. The first metro system in the world to enable full mobile phone reception in underground stations and tunnels

2380-621: The 2010s. The world's longest single-operator rapid transit system by route length is the Shanghai Metro . The world's largest single rapid transit service provider by number of stations (472 stations in total) is the New York City Subway . The busiest rapid transit systems in the world by annual ridership are the Shanghai Metro, Tokyo subway system , Seoul Metro and the Moscow Metro . The term Metro

2450-532: The 21st century, most new expansions and systems are located in Asia, with China becoming the world's leader in metro expansion, operating some of the largest and busiest systems while possessing almost 60 cities that are operating, constructing or planning a rapid transit system . Rapid transit is used for local transport in cities , agglomerations , and metropolitan areas to transport large numbers of people often short distances at high frequency . The extent of

2520-831: The Dongguan Municipal Development and Reform Bureau issued the "Adjustment of the Construction and Planning of the Second Phase of Dongguan Urban Rail Transit (2019-2024), that is, the Planning of the Line Network (Adjustment)", adding Line 1 Phase II and III as well as branches to Line 1 and 3. In March 2022, the National Development and Reform Commission approved the second phase construction planning adjustment plan, in which

2590-609: The Line 1 were being carried out. On February 19, 2019 Line 1 Phase 1 started construction. Construction of the Shenzhen section of Line 1 started as part of Shenzhen Metro 's Phase IV expansion as the Line 6 branch line project. The complete Line 1 has a total length of 57.46 kilometers and runs from northwest to southeast with 25 stations. Line 3 feasibility study, survey, design and other preliminary work has begun. CRRC Guangdong, CRRC Nanjing Puzhen and Bombardier Transportation

2660-638: The Pearl River Delta region intercity rail transit construction plan, in 2010 the planning was further adjusted to increase planned line length to 218 kilometres and 76 stations. Network construction period was extended to 2025. In December 2013, with the consent of the State Council, the NDRC approved the short-term construction plan for urban rail transit in Dongguan (2013-2019). According to

2730-548: The Provincial Development and Reform Commission. December 2006, plan submitted to the National Development and Reform Commission . February 2007, the mayor of Dongguan, Li Yuquan announced provincial government approval; In 2006, September 25 to 26, "Dongguan city rapid rail transit construction plan" expert review meeting was held and the "Dongguan City Rapid Rail Transit Construction Plan"

2800-498: The approval, the newly-added construction lines approved by the state in Dongguan City are Line 1 Phase I, Line 2 Phase II and Line 3 Phase I, with a total length of 126.9 kilometers. The second phase of the project, a total of 164.6 kilometers of urban rail transit lines in Dongguan City, has been approved by the state. April 13, 2009, Dongguan railway station (formerly New Dasan Station) construction officially started, also

2870-478: 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

2940-484: The country seeking factory jobs. Humen is geographically advantageous for the factories due to its proximity to two large metropolitan cities and export harbors of Hong Kong and mainland China's Shenzhen . Humen is an important gateway to south China. Going upstream, ships in the Pearl River can reach the eastern, northern and western regions of Guangdong and even parts of Guangxi province. The main port, Humen Port,

3010-414: 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

3080-611: The entire metropolitan area is called Metra (short for Met ropolitan Ra il), while its rapid transit system that serves the city is called the "L" . 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

3150-453: The first phase of Line 1 and Line 3 were optimized and adjusted, and the planning period was adjusted to 2022-2027. On August 26, 2022, the groundbreaking ceremony for the south extension of Dongguan Rail Transit Line 2 was held in Humen Town . The extension is 17.1 km long with 9 station and will directly serve Humen Town Center after its opening planned for 2027. In 2015, the feasibility study, survey and design and other preliminary work of

3220-516: The floor rather than resting on ballast , such as normal railway tracks. An alternate technology, using rubber tires on narrow concrete or steel roll ways , was pioneered on certain lines of the Paris Métro and Mexico City Metro , and the first completely new system to use it was in Montreal , Canada. On most of these networks, additional horizontal wheels are required for guidance, and

3290-439: The interconnections between different parts of the system; for example, they show the interchange stations where passengers can transfer between lines. Unlike conventional maps, transit maps are usually not geographically accurate, but emphasize the topological connections among the different stations. The graphic presentation may use straight lines and fixed angles, and often a fixed minimum distance between stations, to simplify

3360-602: The lines of the Lyon Metro includes a section of rack (cog) railway , while the Carmelit , in Haifa, is an underground funicular . 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

3430-557: The main rapid transit system. For instance, the Wenhu Line of the Taipei Metro serves many relatively sparse neighbourhoods and feeds into and complements the high capacity metro lines. 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

3500-418: 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

3570-402: 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

3640-958: 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

3710-603: 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

3780-587: 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

3850-471: The proposal was rejected with Line 1 and Guangzhou-Shenzhen intercity railway built as separate lines. July 2009, "Dongguan city rapid rail transit construction plan (2009-2015)" was put to the NDRC and the Ministry of Construction for approval. Approval was granted to build Line 2 Phase I and II , totaling 37.8 km. City rail transit construction project formally entered operational phase. To cope with

3920-908: 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

3990-542: 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

4060-501: The starting point of the Metro Line. The subway station hall project to be constructed simultaneously. On March 26, 2010 Dongguan Metro Line 1 Phase 1 officially started. December 8, 2014, the two shield tunnel borers break through to Shan Mei ~ Exhibition Centre, marking the second line main project completion. According to the plan, completion for trial operations is to be December 29, 2015. Line 2 opened on 27 May 2016. In 2019,

4130-663: 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

4200-646: 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

4270-414: 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

4340-511: 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

4410-488: 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

4480-522: Was 838,144 in the 2020 census, making it the second most populous town ( zhèn ) in China (after Chang'an in Dongguan as well). The history of Humen is linked to the First Opium War (1839–1842). It was at Humen that Lin Zexu supervised the destruction of large quantities of seized opium in 1839. Some major battles in the First Opium War were fought here and on the waters of the Bocca Tigris. Humen has many consumer goods factories. These factories fueled population expansion from emigrating workers around

4550-411: 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

4620-484: Was approved. Experts recommended that the initial scale of the plan be brought down to about 60km and give priority to the development of Line 2. Experts also note that the, at the time planned, Guangzhou–Shenzhen intercity railway overlaps with the proposed Line 1 and suggested further research to be made to allow for unified coordination and optimization of both lines. It was suggested that both lines should share tracks to avoid duplication and reduce investment. However,

4690-399: Was called R2 in planning. In 2001, when he was with the party secretary of Dongguan, Tong Xing used the slogan "a big year for five years to see Metro". The vision to build the Dongguan Rail Transit system was first put on the agenda. September 2003 to October 2004, China Academy of Urban Planning and Design Institute of Ministry of Railways, "Dongguan Rail Transit Network Planning" project

4760-738: 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

4830-401: Was launched. November 2004, Dongguan City rail transit construction leading group was established, followed by the development of "Dongguan Rail Transit Network Plan" to be completed by 2020. Dongguan City plans to build a total length of 195 km, with the total number of stations to 55 of the rail network. September 2006, "Dongguan City Rapid Rail Transit Construction Plan" passed through

4900-476: 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
