134-497: [REDACTED] The Moscow Metro is a metro system serving the Russian capital of Moscow as well as the neighbouring cities of Krasnogorsk , Reutov , Lyubertsy and Kotelniki in Moscow Oblast . Opened in 1935 with one 11-kilometre (6.8 mi) line and 13 stations, it was the first underground railway system in the Soviet Union . As of September 2024, the Moscow Metro had 297 stations and 519.4 km (322.7 mi) of route length, excluding light rail Monorail, making it

268-425: A 20-kilometre (12 mi) long circle which enables passenger travel between these diameters, and the new Moscow Central Circle (line 14) and even newer Bolshaya Koltsevaya line (line 11) form a 54-kilometre (34 mi) and 57-kilometre (35 mi) long circles respectively that serve a similar purpose on middle periphery. Most stations and lines are underground, but some lines have at-grade and elevated sections;

402-425: 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

536-454: 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

670-651: 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

804-583: 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

938-405: 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

1072-800: A few out of more than sixty tram systems in Russia are not broad gauge: 1,000 mm in Kaliningrad and Pyatigorsk , 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) in Rostov-on-Don . There are two tram systems in and around Yevpatoria that use 1,000 mm ( 3 ft  3 + 3 ⁄ 8  in ) gauge. Finland's Helsinki trams and Latvia's Liepāja trams use 1,000 mm ( 3 ft  3 + 3 ⁄ 8  in ). Estonia's Tallinn trams use similar 1,067 mm ( 3 ft 6 in ). Warsaw's tramway system, constructed with 1525 mm gauge,

1206-418: 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

1340-652: 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 ,

1474-705: A larger gauge could be viable for railways isolated from the extant 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) gauge Western European network. In 1840, work started on the second railway in the Russian Empire , the Warsaw–Vienna railway in Congress Poland . It was a 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge , with the express intention of allowing through-freight trains into Austria-Hungary . The modern Russian railway network solidified around

1608-452: 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

1742-615: 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

1876-548: A part of the Filyovskaya Line . The stations, too, were supplied with tight gates and life-sustenance systems to function as proper nuclear shelters. In the further development of the Metro the term "stages" was not used any more, although sometimes the stations opened in 1957–1959 are referred to as the "fifth stage". During the late 1950s and throughout the 1960s, the architectural extravagance of new Metro stations

2010-615: A rapid transit setting. Russian gauge Railways with a railway track gauge of 5 ft ( 1,524 mm ) first appeared in the United Kingdom and the United States. This gauge became commonly known as " Russian gauge ", because the government of the Russian Empire chose it in 1843. Former areas and states of the Empire (such as Finland ) have inherited this standard. However in 1970, Soviet Railways re-defined

2144-600: A result of the Russo-Japanese War of 1904-1905, its southernmost section from Changchun to Lüshun was lost to the Japanese, who promptly regauged it to standard gauge , after using the narrow 3 ft 6 in ( 1,067 mm ) for a short time during the war. This formed a break of gauge between Changchun and Kuancheng , the station just to the north of Changchun, still in Russian hands, until

2278-435: A similar look due to the extensive use of same-sized white or off-white ceramic tiles with hard-to-feel differences. Walls with cheap ceramic tiles were susceptible to train-related vibration: some tiles would eventually fall off and break. It was not always possible to replace the missing tiles with the ones of the exact color and tone, which eventually led to variegated parts of the walls. The contrasting style gap between

2412-743: A single gold-plated decorative pane known as "Tree of peoples' of USSR" or additional station hall for Tretyakovskaya to house cross-platform interchange system between line 6 and line 8. To this day, Tretyakovskaya metro station consists of two contrasting halls: brutalistic 1971 hall and custom design hall from 1986 reminiscent of Tretyakovskaya Galereya museum located within walking distance. 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

2546-565: 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

2680-467: A standardized logo of the network as part of a broader rebranding of the Moscow Transport. The Moscow Metro, a state-owned enterprise , is 449 km (279 mi) long and consists of 15 lines and 263 stations organized in a spoke-hub distribution paradigm , with the majority of rail lines running radially from the centre of Moscow to the outlying areas. The Koltsevaya Line (line 5) forms

2814-608: 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

2948-532: A technique which the Metrostroi factory had only just mastered. The Taganskaia Metro Station on the Ring Line was designed in...quite another style by the architects K.S. Ryzhkov and A. Medvedev... Their subject matter dealt with images of war and victory...The overall effect was one of ceremony ... In the platform halls the blue ceramic bodies of the chandeliers played a more modest role, but still emphasised

3082-475: A top speed of 80 km/h (50 mph). In comparison, New York City Subway trains averaged a slower 25 miles per hour (40 km/h) and had a top speed of 45 miles per hour (72 km/h). While the celebration was an expression of popular joy it was also an effective propaganda display, legitimizing the Metro and declaring it a success. The initial line connected Sokolniki to Okhotny Ryad then branching to Park Kultury and Smolenskaya . The latter branch

3216-413: A tourist attraction in itself, thanks to its lavish interior decoration. The Moscow Metro is a world leader in the frequency of train traffic, as intervals during peak hours often do not exceed 90 seconds. In February 2023, Moscow was the first in the world to reduce the intervals of metro trains to 80 seconds, but in practice trains are not likely to exceed the 90 seconds interval. The full legal name of

3350-801: 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

3484-608: 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

3618-633: Is announced by a male voice on inbound trains to the city center (on the Circle line , the clockwise trains), and by a female voice on outbound trains (anti-clockwise trains on the Circle line). The metro has a connection to the Moscow Monorail , a 4.7-kilometre (2.9 mi), six-station monorail line between Timiryazevskaya and VDNKh which opened in January 2008. Prior to the official opening,

3752-506: 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

3886-416: 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

4020-555: 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

4154-412: 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

4288-748: 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

4422-528: The 5 ft gauge that was laid during canal construction. The first rail line in Finland was opened in January 1862. As Finland was then the Grand Duchy of Finland , an autonomous state ruled in personal union by Imperial Russia where railways were also built to the (5 ft) broad track gauge of 1,524 mm ( 5 ft ). However the railway systems were not connected until the bridge over

4556-521: The 8th-longest in the world , the longest in Europe and the longest outside China. It is also the only system with three circle lines. The system is mostly underground, with the deepest section 73 m (240 ft) underground at the Park Pobedy station, one of the world's deepest underground stations. It is the busiest metro system in Europe, the busiest in the world outside Asia, and is considered

4690-627: 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

4824-500: The Filyovskaya Line , Butovskaya Line and the Central Circle Line are the three lines that are at grade or mostly at grade. The Moscow Metro uses 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ) Russian gauge , like other Russian railways, and an underrunning third rail with a supply of 825 Volts DC , except lines 13 and 14, the former being a monorail, and the latter being directly connected to

4958-752: 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

5092-429: 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

5226-740: 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

5360-578: 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

5494-589: 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

5628-770: The River Tyne . In 1839, the Eastern Counties Railway was constructed. In 1840, the Northern and Eastern Railway was built. In 1844, both lines were converted to 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge . In 1903, the East Hill Cliff Railway , a funicular , was opened. In 1827, Horatio Allen , the chief engineer of the South Carolina Canal and Rail Road Company , prescribed

5762-639: The Saint Petersburg–Moscow railway , built in 1842. There, the Tsar established a committee to recommend technical standards for the building of Russia's first major railway. The team included devotees of Franz Anton von Gerstner , who pushed to continue the Tsarskoye Selo gauge, and engineer Pavel Melnikov and his consultant George Washington Whistler , a prominent American railway engineer. Whistler recommended 5 ft ( 1,524 mm ) on

5896-685: 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

6030-764: The break of gauge did pose some amount of obstacle to the invading Germans. The 5-foot gauge became the standard in the Russian Empire and later the Soviet Union. Russian engineers used it on the Chinese Eastern Railway , built in the closing years of the 19th century across the Northeastern China entry to provide a shortcut for the Trans-Siberian Railway to Vladivostok . The railway's southern branch, from Harbin via Changchun to Lüshun , used Russian gauge. As

6164-450: 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

6298-409: 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

6432-432: 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

6566-506: The 1990s and 2000s, Lenin's name was excluded from the signage on newly built and reconstructed stations. In 2016, a Metro representative stated that Lenin's name would remain on station name plates as it aligns with the official name of the company, unchanged since the Soviet era. The first official name of the metro was L. M. Kaganovich Metro ( Метрополитен им. Л.М. Кагановича ) after Lazar Kaganovich (see History section). However, when

6700-488: 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

6834-621: 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

6968-532: 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

7102-828: The Bolshaya Koltsevaya line, which became fully functional on 1 March 2023. Its new stations included Pechatniki, Nagatinsky Zaton and Klenovy Bulvar. The first plans for a metro system in Moscow date back to the Russian Empire but were postponed by World War I , the October Revolution and the Russian Civil War . In 1923, the Moscow City Council formed the Underground Railway Design Office at

7236-717: The Crimea, the Caucasus, the Urals, and the Soviet Far East Skilled engineers were scarce, and unskilled workers were instrumental to the realization of the metro. The Metrostroi (the organization responsible for the Metro's construction) conducted massive recruitment campaigns. It printed 15,000 copies of Udarnik metrostroia ( Metrostroi Shock Worker , its daily newspaper) and 700 other newsletters (some in different languages) to attract unskilled laborers. Kaganovich

7370-499: The Kaluzhskaia station ( Oktyabrskaya nowadays, not to be confused with contemporary "Kaluzhskaya" station on line 6). The work of Abram Damsky further publicized these ideas hoping people would associate the party with the idea of bright future. The Kaluzhskaya Station was designed by the architect [Leonid] Poliakov. Poliakov's decision to base his design on a reinterpretation of Russian classical architecture clearly influenced

7504-495: The Metro at its debut, and its design was greeted with pride; street celebrations included parades, plays and concerts. The Bolshoi Theatre presented a choral performance by 2,200 Metro workers; 55,000 colored posters (lauding the Metro as the busiest and fastest in the world) and 25,000 copies of "Songs of the Joyous Metro Conquerors" were distributed. The Moscow Metro averaged 47 km/h (29 mph) and had

7638-430: The Metro stations almost finished at the time of the ban (such as VDNKh and Alexeyevskaya ) got their final decors simplified: VDNKh's arcs/portals, for example, got plain green paint to contrast with well-detailed decorations and pannos around them. A typical layout of the cheap shallow-dug metro station (which quickly became known as Sorokonozhka – "centipede", from early designs with 40 concrete columns in two rows)

7772-521: The Metro was awarded the Order of Lenin , it was officially renamed Moscow Order of Lenin L. M. Kaganovich Metro ( Московский ордена Ленина Метрополитен им. Л. М. Кагановича ) in 1947. When the metro was renamed in 1955, the Okhotny Ryad station was renamed as "Imeni Kaganovicha" in honor of Lazar Kaganovich. In 1957, the original Okhotny Ryad name of the station was reinstated. The first line of

7906-591: The Metro was named after him until 1955 ( Metropoliten im. L.M. Kaganovicha ) . The Moscow Metro construction engineers consulted with their counterparts from the London Underground , the world's oldest metro system, in 1936: British architect Charles Holden and administrator Frank Pick had been working on the station developments of the Piccadilly Line extension, and Soviet delegates to London were impressed by Holden's thoroughly modern redeployment of classical elements and use of high-quality materials for

8040-413: The Moscow Board of Urban Railways. It carried out preliminary studies, and by 1928 had developed a project for the first route from Sokolniki to the city centre. At the same time, an offer was made to the German company Siemens Bauunion to submit its own project for the same route. In June 1931, the decision to begin construction of the Moscow Metro was made by the Central Committee of the Communist Party of

8174-428: The Moscow Metro is considered to have reached its zenith in these stations. The Koltsevaya Line was first planned as a line running under the Garden Ring , a wide avenue encircling the borders of Moscow's city centre. The first part of the line – from Park Kultury to Kurskaya (1950) – follows this avenue. Plans were later changed and the northern part of the ring line runs 1–1.5 kilometres (0.62–0.93 mi) outside

8308-470: The Moscow Metro since 2 December 2014. Download coordinates as: Each line is identified by a name, an alphanumeric index (usually consisting of just a number, and sometimes a letter suffix), and a colour. The colour assigned to each line is its colloquial identifier, except for the nondescript greens and blues assigned to the Bolshaya Koltsevaya , the Lyublinsko-Dmitrovskaya , and Butovskaya lines (lines 11, 10, and 12, respectively). The upcoming station

8442-403: The Moscow Metro was launched in 1935, complete with the first logo , the capital M paired with the text "МЕТРО". There is no accurate information about the author of the logo, so it is often attributed to the architects of the first stations – Samuil Kravets, Ivan Taranov and Nadezhda Bykova. At the opening in 1935, the M letter on the logo had no definite shape. In 2014, the Moscow Metro adopted

8576-490: The Moskva River through a deep tunnel) and Kurskaya – Partizanskaya (four stations) were inaugurated in 1943 and 1944 respectively. War motifs replaced socialist visions in the architectural design of these stations. During the Siege of Moscow in the fall and winter of 1941, Metro stations were used as air-raid shelters; the Council of Ministers moved its offices to the Mayakovskaya platforms, where Stalin made public speeches on several occasions. The Chistiye Prudy station

8710-404: The River Neva was built in 1913. Russian trains could not have run on Finnish tracks, because the Finnish loading gauge was narrower, until the connection was made and the Finnish structure gauge was widened. In the late 1960s the gauge was redefined to 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ) in the Soviet Union. At the same time the tolerances were tightened. As

8844-407: The Sadovoye Koltso, thus providing service for seven (out of nine) rail terminals. The next part of the Koltsevaya Line opened in 1952 (Kurskaya– Belorusskaya ), and in 1954 the ring line was completed. When the Metro opened in 1935, it immediately became the centrepiece of the transportation system (as opposed to horse-carried barrows still widely used in 1930s Moscow). It also became the prototype,

8978-405: The Soviet Union . In January 1932 the plan for the first lines was approved, and on 21 March 1933 the Soviet government approved a plan for 10 lines with a total route length of 80 km (50 mi). The first lines were built using the Moscow general plan designed by Lazar Kaganovich , along with his project managers (notably Ivan M. Kuznetsov and, later, Isaac Y. Segal) in the 1930s–1950s, and

9112-489: The Soviet Union in 1991, Estonia redefined its track gauge to 1,524 mm , to match Finland's gauge. The redefinition did not mean that all the railways in Estonia were changed immediately. It was more a rule change, so that all renovated old tracks and new railways would be constructed in 1,524 mm gauge from then on. (See Track gauge in Estonia .) Finland allows its gauge to be 1,520–1,529 mm on first class lines (classes 1AA and 1A, speed 220–160 km/h). If

9380-486: The architecture was based on that of the most popular stations in existence (Krasniye Vorota, Okhotnyi Ryad and Kropotkinskaya); while following the popular art-deco style, it was merged with socialist themes. The first deep-level column station Mayakovskaya was built at the same time. Building work on the third stage was delayed (but not interrupted) during World War II , and two Metro sections were put into service; Teatralnaya – Avtozavodskaya (three stations, crossing

9514-439: The arrival of the first train, but all stations simultaneously close their entrances at 01:00 for maintenance, and so do transfer corridors. The minimum interval between trains is 90 seconds during the morning and evening rush hours. As of 2017, the system had an average daily ridership of 6.99 million passengers. Peak daily ridership of 9.71 million was recorded on 26 December 2014. Free Wi-Fi has been available on all lines of

9648-564: The basis that it was cheaper to construct than 6 ft ( 1,829 mm ) and cheaper to maintain than 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ). His advice won over the Tsar. At the time, questions of continuity with the European network did not arise. By the time difficulties arose in connecting the Prussian railroads to the Russian ones in Warsaw in the 1850s, it

9782-478: 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

9916-541: The circular ticket hall of Piccadilly Circus , and so engaged Pick and Holden as advisors to Moscow's metro system. Partly because of this connection, the design of Gants Hill tube station , which was completed in 1947, is reminiscent of a Moscow Metro station. Indeed, Holden's homage to Moscow has been described as a gesture of gratitude for the USSR's helpful role in The Second World War . Soviet workers did

10050-577: The city's physical layout. Engineers for the Metropolitan-Vickers Electrical Company (Metrovick) were given a show trial and deported in 1933, ending the role of British business in the USSR. The first line was opened to the public on 15 May 1935 at 07:00 am. It was 11 kilometres (6.8 mi) long and included 13 stations. The day was celebrated as a technological and ideological victory for socialism (and, by extension, Stalinism ). An estimated 285,000 people rode

10184-464: The completion of the Moscow Metro; without industrialization, the Soviet Union would not have had the raw materials necessary for the project. For example, steel was a main component of many subway stations. Before industrialization, it would have been impossible for the Soviet Union to produce enough steel to incorporate it into the metro's design; in addition, a steel shortage would have limited

10318-426: The concept of the lamps, some of which I planned in collaboration with the architect himself. The shape of the lamps was a torch – the torch of victory, as Polyakov put it... The artistic quality and stylistic unity of all the lamps throughout the station's interior made them perhaps the most successful element of the architectural composition. All were made of cast aluminum decorated in a black and gold anodized coating,

10452-451: The deep-dug Shabolovskaya (1980), have the near-tunnel walls decorated with metal sheets, not tiles. Tyoply Stan features a theme related to the name and the location of the station ("Tyoply Stan" used to literally mean warm area ): its walls are covered in brick-colored ribbed panes, which look like radiators ). Downtown area got such stations as Borovitskaya (1986), with uncovered red bricks and gray, concrete-like colors accompanying

10586-570: The design was useful for demonstrating the extra structural strength of the underground works (as in Metro doubling as bunkers , bomb shelters). The chief lighting engineer was Abram Damsky, a graduate of the Higher State Art-Technical Institute in Moscow. By 1930 he was a chief designer in Moscow's Elektrosvet Factory, and during World War II was sent to the Metrostroi (Metro Construction) Factory as head of

10720-414: 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

10854-611: 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

10988-516: 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

11122-482: The gauge as 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ). With about 225,000 km (140,000 mi) of track, 1,520 mm is the second-most common gauge in the world, after 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge . In 1748, the Wylam waggonway was built to a 5 ft ( 1,524 mm ) gauge for the shipment of coal from Wylam to Lemington down

11256-650: The gauge of 5 ft or 1,520 mm, include: Short sections of Russian or 5 ft gauge extend into Poland , eastern Slovakia , Sweden (at the Finnish border at Haparanda ), and northern Afghanistan . There is an approximately 150 km long section in Hungary in the Záhony logistics area close to the Ukrainian border. Following renovations in 2014, a 32 km section of dual Standard /Russian gauge

11390-479: The gauge then used by the Pennsylvania Railroad . In 1837, the first railway built in Russia was a 6 ft ( 1,829 mm ) gauge, 17 km long experimental line connecting Saint Petersburg with Tsarskoye Selo and Pavlovsk . The choice of gauge was influenced by Brunel 's Great Western Railway which used 7 ft ( 2,134 mm ). The Tsarskoye Selo railway's success proved that

11524-439: 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

11658-533: The labour and the art work, but the main engineering designs, routes, and construction plans were handled by specialists recruited from London Underground. The British called for tunnelling instead of the " cut-and-cover " technique, the use of escalators instead of lifts, the routes and the design of the rolling stock. The paranoia of the NKVD was evident when the secret police arrested numerous British engineers for espionage because they gained an in-depth knowledge of

11792-489: The lighting shop. Damsky recognized the importance of efficiency, as well as the potential for light as an expressive form. His team experimented with different materials (most often cast bronze, aluminum, sheet brass, steel, and milk glass) and methods to optimize the technology. Damsky's discourse on "Lamps and Architecture 1930–1950" describes in detail the epic chandeliers installed in the Taganskaya Station and

11926-602: 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

12060-557: 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

12194-577: The mainlines with 3000V DC overhead lines, as is typical. The average distance between stations is 1.7 kilometres (1.1 mi); the shortest (502 metres (1,647 ft) long) section is between Delovoy Tsentr and Mezhdunarodnaya , and the longest (6.62 kilometres (4.11 mi) long) is between Krylatskoye and Strogino . Long distances between stations have the positive effect of a high cruising speed of 41.7 kilometres per hour (25.9 mph). The Moscow Metro opens at 05:25 and closes at 01:00. The exact opening time varies at different stations according to

12328-1283: The maximum height and width for railway vehicles and their loads, is larger for Russian gauge. This means that if a standard gauge railway, in Europe, is adapted for dual gauge , bridges must be rebuilt, double tracks must be placed further apart and the overhead wire must be raised. Or there must be restrictions on permitted rolling stock, which would restrict the benefit of such a railway. Dual gauge needs more width than single gauge. For double stacking on Russian gauge tracks, maximum height shall be 6.15 or 6.4 m (20 ft 2 in or 21 ft 0 in) above rails. For standard gauge railways, double stacking maximum height shall be 6.15 m (20 ft 2 in). For Indian gauge railways, double stacking maximum height shall be 7.1 m (23 ft 4 in), and minimum overhead wiring height shall be 6.5 or 6.75 m (21 ft 4 in or 22 ft 2 in) above rails. Minimum overhead wiring height for double stacking, standard gauge railways shall be 6.5 m (21 ft 4 in), and Indian gauge railways shall be 7.45 m (24 ft 5 in) above rails, respectively. This would apply to Russia and Europe (or North America), rather than to Russia and China (or Iran). The primary countries currently using

12462-500: The metro has been Moscow Order of Lenin and Order of the Red Banner of Labor V.I. Lenin Metro ( Московский ордена Ленина и ордена Трудового Красного Знамени метрополитен имени В.И. Ленина ) since 1955. This is usually shortened to V.I. Lenin Metro ( Метрополитен им. В.И. Ленина ). This shorter official name appears on many stations. Although there were proposals to remove Lenin from the official name, it still stands. During

12596-488: The monorail had operated in "excursion mode" since 2004. Also, from 11 August 1969 to 26 October 2019, the Moscow Metro included Kakhovskaya line 3.3 km (2.1 mi) long with 3 stations, which closed for a long reconstruction. On 7 December 2021, Kakhovskaya is reopened after reconstruction as part of the Bolshaya Koltsevaya line . The renewed Varshavskaya and Kashirskaya stations reopened as part of

12730-418: 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

12864-411: The newly routed commercial cross-isthmus railway. In 2000 the gauge for the commercial parallel railway was changed to 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) to use standard gauge equipment. The original gauge was chosen under the influence of the pre-conversion southern United States railway companies. The electric manoeuvering locomotives along the locks ( mules ) still use

12998-402: 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

13132-523: The northern part of the island in 1930-1932 (Moskalvo-Okha). The railway has no fixed connection with the mainland. Before 2019, rail cars coming from the mainland port of Vanino on the Vanino-Kholmsk train ferry , operating since 1973, had to have their bogies changed in the Sakhalin port of Kholmsk . In 2004 and 2008 plans were put forward to convert it to the Russian gauge. The conversion

13266-958: 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

13400-603: 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

13534-587: 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

13668-412: The overall expressiveness of the lamp. Stalin's first five-year plan (1928–1932) facilitated rapid industrialization to build a socialist motherland. The plan was ambitious, seeking to reorient an agrarian society towards industrialism. It was Stalin's fanatical energy, large-scale planning, and resource distribution that kept up the pace of industrialization. The first five-year plan was instrumental in

13802-487: The power to mobilize; because the party was a single source of control, it could focus its resources. The most notable example of mobilization in the Soviet Union occurred during World War II . The country also mobilized in order to complete the Moscow Metro with unprecedented speed. One of the main motivation factors of the mobilization was to overtake the West and prove that a socialist metro could surpass capitalist designs. It

13936-576: The powerfully decorated stations of Moscow's center and the spartan-looking stations of the 1960s was eventually filled. In the mid-1970s the architectural extravagance was partially restored. However, the newer design of shallow "centipede" stations (now with 26 columns, more widely spaced) continued to dominate. For example, Kaluzhskaya "centipede" station from 1974 (adjacent to Novye Cheryomushki station) features non-flat tiles (with 3D effect utilized), and Medvedkovo from 1978 features complex decorations. 1971 station Kitay-Gorod ("Ploshchad Nogina" at

14070-908: 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

14204-490: The rest of the former Chinese Eastern Railway was converted to standard gauge, probably in the 1930s. Unlike in South Manchuria , the Soviet Union's reconquest of southern Sakhalin from Japan did not result in regauging of the railway system. Southern Sakhalin has continued with the original Japanese 1,067 mm ( 3 ft 6 in ) gauge simultaneously with the Russian gauge railway, constructed in

14338-462: The rolling stock's tolerance is kept within certain limits, through running between 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ) railways and Finnish 1,524 mm ( 5 ft ) railways is allowed. Since both 1,520 and 1,524 mm tolerances overlap, the difference is negligible. The international high-speed Allegro 's gauge between Helsinki and St. Petersburg was specified as 1,522 mm. The loading gauge , which defines

14472-542: 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

14606-498: The running gear ( wheelsets ) of the rolling stock remained unaltered, the result was an increased speed and stability. The conversion took place between 1970 and the beginning of the 1990s. In Finland, the Finnish State Railways kept the original definition of 1,524 mm ( 5 ft ), even though they also have tightened the tolerances in a similar way, but to a higher level. After its independence from

14740-626: The size of the subway system and its technological advancement. The Moscow Metro furthered the construction of a socialist Soviet Union because the project accorded with Stalin's second five-year plan . The Second Plan focused on urbanization and the development of social services. The Moscow Metro was necessary to cope with the influx of peasants who migrated to the city during the 1930s; Moscow's population had grown from 2.16 million in 1928 to 3.6 million in 1933. The Metro also bolstered Moscow's shaky infrastructure and its communal services, which hitherto were nearly nonexistent. The Communist Party had

14874-663: 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

15008-714: 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

15142-414: 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

15276-495: The time) features cross-platform interchange (Line 6 and line 7). Although built without "centipede" design or cheap ceramic tiles, the station utilizes near- grayscale selection of colors. It is to note the "southbound" and "northbound" halls of the station have identical look. Babushkinskaya station from 1978 is a no-column station (similar to Biblioteka Imeni Lenina from 1935). 1983 Chertanovskaya station has resemblance to Kropotkinskaya (from 1935). Some stations, such as

15410-511: 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

15544-688: The usage of 5 ft ( 1,524 mm ) gauge. Many other railroads in the Southern United States adopted this gauge. The presence of several distinct gauges was a major disadvantage to the Confederate States of America during the American Civil War . In 1886, when around 11,500 miles (18,500 km) of 5 ft gauge track existed in the United States, almost all of the railroads using that gauge were converted to 4 ft 9 in ( 1,448 mm ),

15678-601: 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

15812-558: The vision for future Soviet large-scale technologies. The artwork of the 13 original stations became nationally and internationally famous. For example, the Sverdlov Square subway station featured porcelain bas-reliefs depicting the daily life of the Soviet peoples, and the bas-reliefs at the Dynamo Stadium sports complex glorified sports and physical prowess on the powerful new " Homo Sovieticus " (Soviet man). The metro

15946-559: 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

16080-597: Was also walled off, and the headquarters of the Air Defence established there. After the war ended in 1945, construction began on the fourth stage of the Metro, which included the Koltsevaya Line , a deep part of the Arbatsko-Pokrovskaya line from Ploshchad Revolyutsii to Kievskaya and a surface extension to Pervomaiskaya during the early 1950s. The decoration and design characteristic of

16214-642: Was closely involved in the recruitment campaign, targeting the Komsomol generation because of its strength and youth. The beginning of the Cold War led to the construction of a deep section of the Arbatsko-Pokrovskaya Line . The stations on this line were planned as shelters in the event of nuclear war. After finishing the line in 1953 the upper tracks between Ploshchad Revolyutsii and Kiyevskaya were closed, and later reopened in 1958 as

16348-463: Was completed in 2019. There were proposals in 2013 for north-south and east-west lines in Afghanistan, with construction to start in 2013. The Panama Canal Railway , first constructed in ca. 1850, was built in 5 ft ( 1,524 mm ) gauge. During canal construction (1904–1914), this same gauge was chosen for both construction traffic, canal operating services along the quays, and

16482-453: Was decisively rejected on the orders of Nikita Khrushchev . He had a preference for a utilitarian "minimalism"-like approach to design, similar to Brutalism style . The idea behind the rejection was similar to one used to create Khrushchyovkas : cheap yet easily mass-produced buildings. Stations of his era, as well as most 1970s stations, were simple in design and style, with walls covered with identical square ceramic tiles. Even decorations at

16616-590: Was determined to realise the Moscow Metro, regardless of cost. Without Kaganovich's managerial ability, the Moscow Metro might have met the same fate as the Palace of the Soviets : failure. This was a comprehensive mobilization; the project drew resources and workers from the entire Soviet Union. In his article, archeologist Mike O'Mahoney describes the scope of the Metro mobilization: A specialist workforce had been drawn from many different regions, including miners from

16750-458: Was developed for all new stations, and the stations were built to look almost identical, differing from each other only in colours of the marble and ceramic tiles. Most stations were built with simpler, cheap technology; this resulted in utilitarian design being flawed in some ways. Some stations such as adjacent Rechnoi Vokzal and Vodny Stadion or sequiential Leninsky Prospect , Akadmicheskaya , Profsoyuznaya and Novye Cheryomushki would have

16884-899: 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

17018-592: Was especially important to the Soviet Union that socialism succeed industrially, technologically, and artistically in the 1930s, since capitalism was at a low ebb during the Great Depression. The person in charge of Metro mobilization was Lazar Kaganovich . A prominent Party member, he assumed control of the project as chief overseer. Kaganovich was nicknamed the "Iron Commissar"; he shared Stalin's fanatical energy, dramatic oratory flare, and ability to keep workers building quickly with threats and punishment. He

17152-794: Was extended westwards to a new station ( Kiyevskaya ) in March 1937, the first Metro line crossing the Moskva River over the Smolensky Metro Bridge . The second stage was completed before the war . In March 1938, the Arbatskaya branch was split and extended to the Kurskaya station (now the dark-blue Arbatsko-Pokrovskaya Line ). In September 1938, the Gorkovskaya Line opened between Sokol and Teatralnaya . Here

17286-1101: Was installed between Tumangang and Rajin stations in North Korea. The most western 1,520 mm gauge railway is the Polish LHS ( Linia Hutnicza Szerokotorowa ) from the Ukrainian border to the eastern end of the Upper Silesian Industrial Region . Although broad gauge is quite rare on lighter railways and street tramways worldwide, almost all tramways in the former USSR are broad gauge (according to terminology in use in these countries, gauges narrower than 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ) are considered to be narrow). Many tramway networks initially built to narrow gauges ( 750 mm or 2 ft  5 + 1 ⁄ 2  in or 1,000 mm or 3 ft  3 + 3 ⁄ 8  in metre gauge ) were converted to broad gauge. As of 2015, only

17420-702: 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

17554-488: Was regauged to 1435 mm during post-WWII reconstruction. Tampere tramway , built in 2021, uses 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ). Underground urban rapid transit systems in the former USSR, like the Moscow Metro , Saint Petersburg Metro , Kyiv Metro and Yerevan Metro use Russian gauge ( 1,520 mm ). Outside the former USSR, the Helsinki Metro in Finland that utilizes

17688-578: Was rejected. The Moscow Metro was one of the USSR's most ambitious architectural projects. The metro's artists and architects worked to design a structure that embodied svet (literally "light", figuratively "radiance" or "brilliance") and svetloe budushchee (a well-lit/radiant/bright future). With their reflective marble walls, high ceilings and grand chandeliers, many Moscow Metro stations have been likened to an "artificial underground sun". This palatial underground environment reminded Metro users their taxes were spent on materializing bright future ; also,

17822-416: Was too late to change. A persistent myth holds that Imperial Russia chose a gauge broader than standard gauge for military reasons, namely to prevent potential invaders from using the rail system. The Russian military recognized as early as 1841 that operations to disrupt railway track did not depend on the gauge, and should instead focus on destroying bridges and tunnels . However, in both World Wars

17956-514: Was touted as the symbol of the new social order – a sort of Communist cathedral of engineering modernity. The Metro was also iconic for showcasing Socialist Realism in public art. The method was influenced by Nikolay Chernyshevsky , Lenin 's favorite 19th-century nihilist , who stated that "art is no useful unless it serves politics". This maxim sums up the reasons why the stations combined aesthetics, technology and ideology: any plan which did not incorporate all three areas cohesively
