75-547: Ningbo Rail Transit , also known as the Ningbo Metro , is a rapid transit system serving the city of Ningbo , Zhejiang and its suburbs. Six metro lines are being built inside the urban area of Ningbo, serving Haishu , Jiangbei , Zhenhai , Beilun and Yinzhou . The first phase of Line 1 started construction in June 2009 and began to service the public on May 30, 2014. Line 2 began service on September 26, 2015. Ningbo Rail Transit

150-425: 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

225-450: 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

300-646: 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

375-565: 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

450-405: 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

525-418: 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

600-629: 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 ,

675-452: 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

750-589: A main road in Ningbo, crossing the Fenghua River and entering Yinzhou District . It then passes Ningbo East New Town and the town of Qiuga, crossing eastward into Beilun District through China National Highway 329 via elevated line. It then follows Taishan Road to Xiapu Station, the easternmost destination. The construction of the section between Gaoqiao West and Donghuan South Road began in June 2009 and passenger service began on May 30, 2014, making Ningbo Metro Line 1

825-602: 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

900-621: A rapid transit setting. National Development and Reform Commission The National Development and Reform Commission ( NDRC ) is the third-ranked executive department of the State Council of the People's Republic of China , which functions as a macroeconomic management agency. Established as the State Planning Commission, the NDRC has broad administrative and planning control over

975-558: 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

1050-592: 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

1125-770: 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

1200-608: 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

1275-506: 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

1350-503: Is intended to prevent the economy from becoming too hot or cold, as well as to address China's overcapacity in production for sectors like aluminum, iron, steel, and energy. The NDRC works with other departments to formulate policies, including drafting laws and regulations. It monitors Chinese businesses' outbound foreign direct investment to ensure they do not invest in blacklisted projects. The NDRC must approve sensitive projects, including projects in countries that do not recognize

1425-565: Is involved in the foreign aid process through coordinating aid to other countries for climate cooperation. The NDRC is also one of the main government agencies responsible for data collection for the Chinese Social Credit System . The NDRC's Social Development Division has a planning role in cultural industries including sports, tourism, and mass media. The NDRC manages the General Offices several leading groups, including

1500-416: 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

1575-548: 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

1650-412: 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

1725-733: 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

1800-564: Is the second rapid transit system put into service in Zhejiang Province, after Hangzhou Metro . As of December 2021, there are five lines in operation in the Ningbo Rail Transit system. Line 1 is the first metro line serving Ningbo. It stretches in the east–west direction, starting in the western town of Gaoqiao as a viaduct and turning into a tunnel as it approaches Haishu District . The tunnel stretches under Zhongshan Road,

1875-783: The Beijing-Tianjin-Hebei Region, the Leading Group for Promoting the Development of the Yangtze River Economic Belt, the Leading Group for Promoting the Development of the Guangdong-Hong Kong-Macao Greater Bay Area, and the Leading Group for Promoting Comprehensive Deepening of Reform and Opening in Hainan; these are led by the first-ranking vice premier , with the NDRC chairman usually being

1950-605: 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

2025-447: The Hu-Wen administration 's efforts to balance regional development. In 2016, the NDRC and Alibaba Group signed an agreement to promote rural e-commerce development. In 2017, the NDRC announced the creation of China's national carbon emissions trading system . Prior to 2018, it was also responsible for enforcing China's antitrust law , but this function has been transferred to

2100-724: 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

2175-429: 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

2250-722: 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

2325-578: 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

The line will be extended further into Luotuo Town, Zhenhai District. Line 4 starts from Cicheng Station in Cicheng Town and turns south into the North External Ring Viaduct where it turns east–west. After reaching Jiangbei Avenue, it starts to turn underground and deviates from

2550-577: 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

2625-656: 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

2700-562: The State Administration for Market Regulation . In February 2015, the NDRC completed an investigation into Qualcomm , finding that violated the Anti-Monopoly Law by imposing unreasonable requirements for patent licensing. Qualcomm was fined the equivalent of US$ 975 million. Also in 2018, the NDRC's climate policymaking functions were transferred to the newly created Ministry of Ecology and Environment . On 19 December 2020,

2775-450: 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

The body was first established in November 1952 as the State Planning Commission of the Central People's Government . In 1954, it was transformed to the State Planning Commission of the People's Republic of China. The NDRC's functions are to study and formulate policies for economic and social development, maintain

2925-529: The five-year plans of China . The NDRC has responsibilities over economic targets, price policies, market policies, supply-side structural reform, overseas investment, domestic investment policy, regional development strategies, industrial development strategies, major infrastructure projects, consumption policy, innovation-driven development, scientific and technological infrastructure, high-tech industries, social development, basic public services and social development. NDRC's responsibility for large infrastructure

3000-409: 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

3075-779: The "2021-2026 Construction Plan of Ningbo Rail Transit" was approved by NDRC . The plan includes first phase of Lines 6, 7 and 8 as well as extensions to Line 1 and 4, totaling 106.5 km of new lines. Additionally, late stage planning work is underway on two regional express metro lines to Cixi and Xiangshan . CSR Zhuzhou provides 22 six-car trains for Line 1. Some trains are assembled in Ningbo locally. [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

3150-432: 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

3225-480: 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

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

3450-674: The Fenghua River until it reaches Xiaying and turns north. Then the line goes along first Haiyan Road and then Yuanshi Road. Then the line passes the Yong River and reaches its destination, Xingzhuang Road Station. According to the "Ningbo Rail Transit Construction Plan (2013-2020)" approved by the NDRC , Line 1 to Line 4 and the Phase 1 of Line 5 will be completed before 2020, the total length of Ningbo Rail Transit will be 173.1 kilometers. In December 2020,

3525-594: The NDRC announced it established the Private Economy Development Bureau in order monitor the country's private economy, as well as establish regular communication with private businesses. The NDRC is China's main macroeconomic control institution, as well as the top organization in the State Council in matters related to economic policymaking. It oversees the planning system in China, including producing

3600-402: The NDRC published rules for reviewing foreign investment on national security grounds. The rules allow government agencies "to preview, deny and punish foreign investment activities in areas that are deemed as important to national security." In October 2021, the NDRC published rules restricting private capital in "news-gathering, editing, broadcasting, and distribution." On 4 September 2023,

3675-471: The People's Republic of China, projects in countries experiencing civil war or other major domestic difficulties, or projects involving sensitive subject matter like cross-border water issues or weapons production. The NDRC works with the National Health Commission to research demographic trends and formulate policies on population. It promotes sustainable development strategies . The NDRC

3750-630: The balance of economic development, and to guide restructuring of the economic system of mainland China. In March 1998, the commission was renamed into the State Development Planning Commission. It was renamed again in March 2003 to its current name, the National Development and Reform Commission. In 2008, the NDRC issued a set of policies designed to further development the economies of central regions of China, consistent with

3825-474: 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

3900-414: 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

3975-584: 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

4050-505: 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

4125-439: 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

4200-587: 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

4275-944: The main railway station of the city. The route extends northwards into Jiangbei District and turns eastwards until it reaches Lulin Market, where it turns into viaducts before reaching Qingshuipu station in Zhenhai District . This section of Line 2 opened on September 26, 2015. The line was later extended to Honglian station which opened on December 1, 2022. Line 3 is the third metro line in Ningbo. It starts in Fenghua as an elevated line and goes northwards and then goes eastwards and turns into an underground route and enters Chenpodu area in Yinzhou District. Then it goes northwards into Yinzhou Central Area via Ningnan South Road and then turns into Songjiang Middle Road and goes northeast until it reaches

4350-439: 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

4425-418: 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

4500-402: 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

4575-852: 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

4650-437: 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

4725-530: 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

4800-908: 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

4875-401: 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

4950-475: The second subway line in Zhejiang Province. The extension of Line 1 between Donghuan South Road and Xiapu began trial operations on March 19, 2016. Line 2 is the second metro line in Ningbo. It starts near Ningbo Lishe International Airport and stretches eastwards through tunnels. After reaching Yage'er Avenue it turns northwards and passes Ningbo Textile City, after which the route zigzags into Ningbo Coach Center and crosses Ningbo railway station eastwards,

5025-417: 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

5100-646: 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

5175-414: 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

5250-511: 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

5325-488: 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

5400-479: The viaduct to Zhuangqiao railway station where it turns south, crosses Yaojiang River and reaches Ningbo railway station . Then Line 4 goes along Changchun Road, Xingning Road until it reaches Canghai Road and become north–south again. After reaching Shounan Road it turns into southeast direction and reaches Dongqian Lake, its destination. Line 5 starts from Buzheng Station in western Yinzhou District as an underground line. Then it goes along Yinxian Road and passes

5475-540: Was Singapore's Mass Rapid Transit (MRT) system, which launched its first underground mobile phone network using AMPS in 1989.
