89-621: [REDACTED] The Incheon Airport Maglev was a maglev line in South Korea that opened on 3 February 2016 and closed on 1 September 2023. It was the world's second commercially operating unmanned urban maglev line after Japan's Linimo . The trains were lighter, cutting construction costs in half. The majority of construction was completed by November 2012. The maglev linked Incheon International Airport Terminal 1 to Long Term Parking, Incheon Airport Administration Complex, Paradise City entertainment precinct, and Yongyu station and Leisure Complex while crossing Yeongjong Island . The line
178-492: A maglev train accident occurred in Lathen, killing 23 people. It was found to have been caused by human error in implementing safety checks. From 2006 no passengers were carried. At the end of 2011 the operation licence expired and was not renewed, and in early 2012 demolition permission was given for its facilities, including the track and factory. In March 2021 it was reported the CRRC
267-853: A 110 kilometres per hour (68 mph) operating speed. Two more stages are planned of 9.7 kilometres (6 mi) and 37.4 kilometres (23.2 mi). Once completed it will become a circular line. It was shut down in September 2023. Transport System Bögl (TSB) is a driverless maglev system developed by the German construction company Max Bögl since 2010. Its primary intended use is for short to medium distances (up to 30 km) and speeds up to 150 km/h for uses such as airport shuttles . The company has been doing test runs on an 820-meter-long test track at their headquarters in Sengenthal , Upper Palatinate , Germany , since 2012 clocking over 100,000 tests covering
356-533: A 30 percent increase in traction efficiency and a 60 percent increase in speed over the stock in use on the line since. The vehicles entered service in July 2021 with a top speed of 140 km/h (87 mph). CRRC Zhuzhou Locomotive said in April 2020 it is developing a model capable of 200 km/h (120 mph). There are two competing efforts for high-speed maglev systems, i.e., 300–620 km/h (190–390 mph). In
445-496: A 60-metre ramp which was later extended to 980 metres. From the late 1970s to the 1980s five prototypes of cars were built that received designations from TP-01 (ТП-01) to TP-05 (ТП-05). The early cars were supposed to reach the speed up to 100 kilometres per hour (62 mph). The construction of a maglev track using the technology from Ramenskoye started in Armenian SSR in 1987 and was planned to be completed in 1991. The track
534-466: A 90-foot test track in Johnson's basement "absolutely noiseless[ly] and without the least vibration." A series of German patents for magnetic levitation trains propelled by linear motors were awarded to Hermann Kemper between 1937 and 1941. An early maglev train was described in U.S. patent 3,158,765 , "Magnetic system of transportation", by G. R. Polgreen on 25 August 1959. The first use of "maglev" in
623-627: A 908 metres (2,979 ft) track was opened in Hamburg for the first International Transportation Exhibition (IVA 79). Interest was sufficient that operations were extended three months after the exhibition finished, having carried more than 50,000 passengers. It was reassembled in Kassel in 1980. In 1979 the USSR town of Ramenskoye ( Moscow oblast ) built an experimental test site for running experiments with cars on magnetic suspension. The test site consisted of
712-468: A German maglev company, had a test track in Emsland with a total length of 31.5 kilometres (19.6 mi). The single-track line ran between Dörpen and Lathen with turning loops at each end. The trains regularly ran at up to 420 kilometres per hour (260 mph). Paying passengers were carried as part of the testing process. The construction of the test facility began in 1980 and finished in 1984. In 2006,
801-466: A United States patent was in "Magnetic levitation guidance system" by Canadian Patents and Development Limited . In 1912 French-American inventor Émile Bachelet demonstrated a model train with electromagnetic levitation and propulsion in Mount Vernon, New York. Bachelet's first related patent, U.S. patent 1,020,942 was granted in 1912. The electromagnetic propulsion was by attraction of iron in
890-582: A concern at low speeds, and is one of the reasons why JR abandoned a purely repulsive system and adopted the sidewall levitation system. At higher speeds other modes of drag dominate. The drag force can be used to the electrodynamic system's advantage, however, as it creates a varying force in the rails that can be used as a reactionary system to drive the train, without the need for a separate reaction plate, as in most linear motor systems. Laithwaite led development of such "traverse-flux" systems at his Imperial College laboratory. Alternatively, propulsion coils on
979-576: A distance of over 65,000 km as of 2018. In 2018 Max Bögl signed a joint venture with the Chinese company Chengdu Xinzhu Road & Bridge Machinery Co. with the Chinese partner given exclusive rights of production and marketing for the system in China. The joint venture constructed a 3.5 km (2.2 mi) demonstration line near Chengdu , China, and two vehicles were airlifted there in June, 2020. In February 2021

#17328551860941068-597: A high-speed maglev system. Instead, overcoming drag takes the most energy. Vactrain technology has been proposed as a means to overcome this limitation. Despite over a century of research and development, there are only six operational maglev trains today — three in China, two in South Korea, and one in Japan. In the late 1940s, the British electrical engineer Eric Laithwaite , a professor at Imperial College London , developed
1157-647: A magnetic levitation transportation system to replace Korea's current urban transportation means. This train system is the result of a development project started in 1989 within the Korea Institute of Machinery and Materials (KIMM). The Ministry of Land, Infrastructure and Transport contributed 59% of the funds, around ₩ 217.4 billion ( US$ 190.04 million), with Incheon Airport Corporation spending ₩ 78.7 billion ( US$ 68.8 million) amounting to 25%, and Incheon City paying ₩ 18.9 billion ( US$ 16.52 million) which comes to 6%. Additionally, ₩ 100 billion ( US$ 87.42 million)
1246-644: A major concern that the South Korean won banknotes were being counterfeited . This led the government to issue a new series of banknotes, with the 5,000 won note being the first one to be redesigned. Later in 2007, the 1,000 and 10,000 won notes were introduced. On June 23, 2009, the Bank of Korea released the 50,000 won note. The obverse bears a portrait of Shin Saimdang , a prominent 16th-century artist, calligrapher, and mother of Korean scholar Yulgok , also known as Yi I, who
1335-582: A new high-speed maglev line, the Chuo Shinkansen , started in 2014. It is being built by extending the SCMaglev test track in Yamanashi in both directions. The completion date is unknown, with the estimate of 2027 no longer possible following a local governmental rejection of a construction permit. Transrapid 05 was the first maglev train with longstator propulsion licensed for passenger transportation. In 1979,
1424-453: A series of banknotes was issued which, although it gave the denominations in English in won, were, in fact, the first issues of the hwan . The won was reintroduced on June 10, 1962, at a rate of 1 won = 10 hwan. It became the sole legal tender on March 22, 1975, with the withdrawal of the last circulating hwan coins. Its ISO 4217 code is KRW. At the reintroduction of the won in 1962, its value
1513-546: A single car along a short section of track at the fairgrounds. It was removed after the fair. It was shown at the Aoi Expo in 1987 and is now on static display at Okazaki Minami Park. In 1993, South Korea completed the development of its own maglev train, shown off at the Taejŏn Expo '93 , which was developed further into a full-fledged maglev capable of travelling up to 110 kilometres per hour (68 mph) in 2006. This final model
1602-512: A stopper for the current flow. As a result, power is lost. With the Urban Transit Maglev (now referred to as the "Incheon Airport Maglev") in South Korea as a test model, a study was conducted on exploring the relationship between the variation of slip frequency and energy efficiency of regenerative braking. The slip frequency decreases the limit for the regenerative extinction point. After testing, researchers noticed that this decrease of
1691-537: A transfer to the Seoul Metropolitan Subway at AREX 's Incheon International Airport Station and is offered free of charge to anyone to ride, operating between 9 am and 6 pm with 15-minute intervals. The maglev system was co-developed by the South Korea Institute of Machinery and Materials (KIMM) and Hyundai Rotem . It is 6.1 kilometres (3.8 mi) long, with six stations and
1780-493: A vehicle on the Chinese test track hit a top speed of 169 km/h (105 mph). According to the International Maglev Board there are at least four maglev research programmes underway in China at: Southwest Jiaotong University (Chengdu), Tongji University (Shanghai), CRRC Tangshan-Changchun Railway Vehicle Co. , and Chengdu Aircraft Industry Group . The latest high-speed prototype , unveiled in July 2021,
1869-582: A “plan to reduce operating costs”, as annual maintenance fees hit ₩ 6 billion ( US$ 5.24 million). On 17 October 2022, the National Assembly Transportation Committee held an inspection of the Incheon International Airport Corporation. They received stern critiques regarding the cost; it was revealed that Incheon Maglev required ₩ 500 billion ( US$ 437.08 million) of investment over the next 10 years. This

#17328551860941958-772: Is HSST (and its descendant, the Linimo line) by Japan Airlines and the other, which is more well known, is SCMaglev by the Central Japan Railway Company . The development of the latter started in 1969. The first successful SCMaglev run was made on a short track at the Japanese National Railways ' (JNR's) Railway Technical Research Institute in 1972. Maglev trains on the Miyazaki test track (a later, 7 km long test track) regularly hit 517 kilometres per hour (321 mph) by 1979. After an accident destroyed
2047-535: Is derived from the hanja 圓 ( 원 , won ), meaning "round", which describes the shape of the silver dollar. The won was subdivided into 100 jeon ( Korean : 전 ; Hanja : 錢 ; MR : chŏn ), itself a cognate of the Chinese unit of weight mace and synonymous with money in general. The current won (1962 to present) is written in hangul only and does not officially have any hanja associated with it. The Korean won , Chinese yuan and Japanese yen were all derived from
2136-531: Is inter-operable with steel rail tracks and would permit maglev vehicles and conventional trains to operate on the same tracks. MAN in Germany also designed a maglev system that worked with conventional rails, but it was never fully developed. Each implementation of the magnetic levitation principle for train-type travel involves advantages and disadvantages. South Korean won The South Korean won ( Symbol : ₩ ; Code : KRW ; Korean : 대한민국 원 )
2225-458: Is more than the cost of its initial construction. On 16 June 2023, the Construction and Transportation Committee of Incheon City Council approved plans to convert the track from Maglev to orbital tram tracks. The City Council argued that maintenance costs could be cut by up to 35% due to the difficulty and high cost in purchasing parts for Maglev trains. A proposal to cut costs was passed at
2314-537: Is not part of the Seoul Metropolitan Subway System . It was free of charge for all riders. It initially operated between 09:00 and 18:00. Hours had been extended to between 07:30 and 20:00. Departures were every 15 minutes from all stations. It offered a transfer to Incheon International Airport Terminal 1 station of AREX . This maglev line specifically utilized electromagnetic suspension (EMS) and linear induction motor (LIM) propulsion. The train
2403-702: Is now on display at Railworld in Peterborough, together with the RTV31 hover train vehicle. Another is on display at the National Railway Museum in York. Several favourable conditions existed when the link was built: After the system closed in 1995, the original guideway lay dormant until 2003, when a replacement cable-hauled system, the AirRail Link Cable Liner people mover, was opened. Transrapid,
2492-408: Is on the 5,000 won note. This note is the first Korean banknote to feature the portrait of a woman. The release of the 50,000 won note stirred some controversy among shop owners and those with visual impairments due to its similarity in color and numerical denomination with the 5,000 won note. New 100,000 won notes were also announced, but their release was later cancelled due to the controversy over
2581-529: Is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable—changes in distance between the track and the magnets creates strong forces to return
2670-586: Is the official currency of South Korea . A single won is divided into 100 jeon, the monetary subunit. The jeon is no longer used for everyday transactions, and it appears only in foreign exchange rates. The currency is issued by the Bank of Korea , based in the capital city of Seoul . The old "won" was a cognate of the Chinese yuan and Japanese yen , which were both derived from the Spanish-American silver dollar . It
2759-465: Is typically arranged on a series of C-shaped arms, with the upper portion of the arm attached to the vehicle, and the lower inside edge containing the magnets. The rail is situated inside the C, between the upper and lower edges. Magnetic attraction varies inversely with the square of distance, so minor changes in distance between the magnets and the rail produce greatly varying forces. These changes in force are dynamically unstable—a slight divergence from

2848-414: Is typically the case with electrodynamic suspension maglev trains. Aerodynamic factors may also play a role in the levitation of such trains. The two main types of maglev technology are: In electromagnetic suspension (EMS) systems, the train levitates by attraction to a ferromagnetic (usually steel) rail while electromagnets , attached to the train, are oriented toward the rail from below. The system
2937-416: Is used when the speed of the motor exceeds the synchronous speed. When this happens, the motor changes current flow so that the motor brakes. After this happens, the excess power is converted to power for the motor. Plugging braking is used when the supply terminals are switched, but it is criticized as a wasteful practice, because in order to switch the terminals, an external resistor needs to be implemented as
3026-648: The British Rail Research Division in Derby , along with teams at several civil engineering firms, the "transverse-flux" system was developed into a working system. The first commercial maglev people mover was simply called " MAGLEV " and officially opened in 1984 near Birmingham , England. It operated on an elevated 600 metres (2,000 ft) section of monorail track between Birmingham Airport and Birmingham International railway station , running at speeds up to 42 kilometres per hour (26 mph). The system
3115-521: The South Korean National Assembly to redenominate the won by introducing a new won or new unit, equal to 1,000 old won, and worth nearly one U.S. dollar . While proponents cite a more valuable currency unit better projects the strength of the nation's economy, a majority remain opposed to the idea. Reasons cited are: economic harm if done immediately, no issues on public confidence in the won and its inflation rate, limited cost savings, and
3204-552: The Spanish-American silver dollar , a coin widely used for international trade between Asia and the Americas from the 16th to 19th centuries. During the colonial era under the Japanese (1910–45), the won was replaced by the Korean yen which was at par with the Japanese yen. After World War II ended in 1945, Korea was divided , resulting in two separate currencies, both called won, for
3293-557: The Throgs Neck Bridge , James Powell , a researcher at Brookhaven National Laboratory (BNL), thought of using magnetically levitated transportation. Powell and BNL colleague Gordon Danby worked out a maglev concept using static magnets mounted on a moving vehicle to induce electrodynamic lifting and stabilizing forces in specially shaped loops, such as figure-of-8 coils on a guideway. These were patented in 1968–1969. Japan operates two independently developed maglev trains. One
3382-494: The Tracked Hovercraft RTV-31, based near Cambridge, UK, although the project was cancelled in 1973. The linear motor was naturally suited to use with maglev systems as well. In the early 1970s, Laithwaite discovered a new arrangement of magnets, the magnetic river , that allowed a single linear motor to produce both lift and forward thrust, allowing a maglev system to be built with a single set of magnets. Working at
3471-693: The rolling stock for the line. The 4 trains consist of 2 carriages, namely A and B. Each carriage is 6 metres (19 ft 8 in) long, 2.7 metres (8 ft 10 in) wide and 3.45 metres (11 ft 4 in) high, they weigh 19 tonnes (19 long tons; 21 short tons) and have a starting acceleration and service brake of 1.1 m/s (3.6 ft/s). Train systems such as the Incheon Airport Maglev use air brakes and electric brakes . However, magnetic levitation trains use regenerative braking and plugging braking as opposed to normal trains using regenerative braking and air braking. Regenerative braking
3560-467: The 1,000 won note 19. Many modern security features that can be also found in euros , pounds , Canadian dollars , and Japanese yen are included in the banknotes. Some security features inserted in won notes are: For the first time in the world, KOMSCO , the Korean mint, inserted a new substance in the notes to detect counterfeits. This technique is being exported, such as to Europe and North America. As

3738-553: The Bank of Korea. The first issue of 1, 5, 10, 50, 100 and 500 won notes was printed in the UK by Thomas De La Rue . The jeon notes together with a second issue of 10 and 100 won notes were printed domestically by the Korea Minting and Security Printing Corporation . In 1965, 100 won notes (series III) were printed using intaglio printing techniques, for the first time on domestically printed notes, to reduce counterfeiting. Replacements for
3827-423: The British 500 won notes followed in 1966, also using intaglio printing, and for the 50 won notes in 1969 using lithoprinting . With the economic development from the 1960s, the value of the 500 won notes fell, resulting in a greater use of cashier's checks with higher fixed denominations as means of payment, as well as an increased use of counterfeited ones. In 1970, the 100 won notes were replaced by coins, with
3916-578: The Incheon City Planning Committee on 26 July 2023. The new plan would reduce the operating time from 13 hours to 6 hours and decrease the number of trains from 103 to 25. It was projected that these changes would cut down annual operating costs from ₩ 8.2 billion ( US$ 7.17 million) to ₩ 5.3 billion ( US$ 4.63 million). On 3 January 2024, Incheon International Airport Corporation announced that operations are expected to resume from March 2024. Hyundai Rotem both developed and manufactured
4005-720: The Incheon Maglev saw just 4000 passengers each day. This is only 11% of expected usage levels. During the coronavirus pandemic, this number reduced by over 90% to just 300 daily passengers on average. The line was temporarily closed from 14 July 2022 due to maintenance and repair of the carriages not being completed on time (required every 3 years) as per the Railroad Safety Act . At the National Assembly Land, Infrastructure and Transport Committee meeting on 22 August 2022, Rep. Heo Jong-sik of Dong-gu, Incheon called for
4094-769: The Korea Institute of Machinery and Materials (known as the KIMM, which is part of the Korea University of Science and Technology ) and Hyundai Rotem . It is 6.1 kilometres (3.8 mi) long, with six stations and a 80 km/h (50 mph) operating speed (the design maximum speed is 110 km/h (68 mph)). This train was part of South Korea's Urban Maglev Program (UMP) which started in December 2006. This program reached out to prominent companies and organizations for rail development, like KIMM and Hyundai. The UMP represents Korea's push for R&D in maglev systems in order to engender
4183-401: The South Korean economy is evolving through the use of electronic payments, coins of the South Korean won are becoming less used by consumers. The Bank of Korea began a trial which would result in the total cessation of the production of coins by depositing change into prepaid cards. As of 2019, however, public participation in this program has decreased. There have been recurring proposals in
4272-660: The South and the North . Both the Southern won and the Northern won replaced the yen at par. The first South Korean won was subdivided into 100 jeon . The South Korean won initially had a fixed exchange rate to the U.S. dollar at a rate of 15 won to 1 dollar. A series of devaluations followed, the later ones, in part, due to the Korean War (1950–53). The pegs were: The first South Korean won
4361-480: The banknote's planned image, featuring the Daedongyeojido map, and not including the disputed Dokdo islands. Also of controversy was the appearance of Kim Ku on the note, who is controversial among the South Korean right. The banknotes include over 10 security features in each denomination. The 50,000 won note has 22 security features, the 10,000 won note 21, the 5,000 won note 17, the 2,000 won note 10 and
4450-454: The coins to make jewelry, the redesign was needed to make the coin more cost-effective to produce. The new coin is made of copper-coated aluminium with a reduced diameter of 18 millimetres (0.71 in), and a weight of 1.22 grams (0.043 oz). Its visual design is the same as the old coin. The new coin was issued on December 18, 2006. The 1 and 5 won coins are rarely in circulation since 1992, and prices of consumer goods are rounded to
4539-414: The distance of 30.5 kilometres (19 mi) in just over 8 minutes. Different maglev systems achieve levitation in different ways, which broadly fall into two categories: electromagnetic suspension (EMS) and electrodynamic suspension (EDS) . Propulsion is typically provided by a linear motor . The power needed for levitation is typically not a large percentage of the overall energy consumption of
SECTION 50
#17328551860944628-457: The downside, the dynamic instability demands fine track tolerances, which can offset this advantage. Eric Laithwaite was concerned that to meet required tolerances, the gap between magnets and rail would have to be increased to the point where the magnets would be unreasonably large. In practice, this problem was addressed through improved feedback systems, which support the required tolerances. Air gap and energy efficiency can be improved by using
4717-537: The field exerted by magnets on the train and the applied field creates a force moving the train forward. The term "maglev" refers not only to the vehicles, but to the railway system as well, specifically designed for magnetic levitation and propulsion. All operational implementations of maglev technology make minimal use of wheeled train technology and are not compatible with conventional rail tracks . Because they cannot share existing infrastructure, maglev systems must be designed as standalone systems. The SPM maglev system
4806-425: The first full-size working model of the linear induction motor . He became professor of heavy electrical engineering at Imperial College in 1964, where he continued his successful development of the linear motor. Since linear motors do not require physical contact between the vehicle and guideway, they became a common fixture on advanced transportation systems in the 1960s and 1970s. Laithwaite joined one such project,
4895-829: The frequency led to a decrease in the conversion time of the phase current back into the system. This decreased the required energy to brake, thus accumulating more regenerated power. Maglev (transport) Maglev (derived from magnetic levitation ) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance . Compared to conventional railways, maglev trains can have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise. However, they are more expensive to build, cannot use existing infrastructure, and use more energy at high speeds. Maglev trains have set several speed records . The train speed record of 603 km/h (375 mph)
4984-457: The guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields. In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system. The magnetic field
5073-418: The guideway are used to exert a force on the magnets in the train and make the train move forward. The propulsion coils that exert a force on the train are effectively a linear motor: an alternating current through the coils generates a continuously varying magnetic field that moves forward along the track. The frequency of the alternating current is synchronized to match the speed of the train. The offset between
5162-506: The intrinsic value of the brass 1 won coin far surpassed its face value, new aluminium 1 won coins were issued to replace them. As an attempt to further reduce currency production costs, new 5 and 10 won coins were issued in 1970, struck in brass. Cupronickel 100 won coins were also introduced that year, followed by cupronickel 50 won coins in 1972. In 1982, with inflation and the increasing popularity of vending machines , 500 won coins were introduced on June 12, 1982. In January 1983, with
5251-592: The maglev theme was continued by the Engineering Research Center "TEMP" (ИНЦ "ТЭМП") this time by the order from the Moscow government . The project was named V250 (В250). The idea was to build a high-speed maglev train to connect Moscow to the Sheremetyevo airport . The train would consist of 64-seater cars and run at speeds up to 250 kilometres per hour (160 mph). In 1993, due to the financial crisis ,
5340-406: The main theme delayed it by a year. Newly designed 500 won notes were also released in 1973, and the need for a medium denomination resulted in the introduction of 1,000 won notes in 1975. In 1982, the 500 won note was replaced by a coin. The following year, as part of its policy of rationalizing the currency system, the Bank of Korea issued a new set of notes, as well as a new set of coins. Some of
5429-439: The nearest 10 won. However, they are still in production, minting limited amounts of these two coins every year, for the Bank of Korea's annual mint sets. In 1998, the production costs per coin were: 10 won coins each cost 35 won to produce, 100 won coins cost 58 won, and 500 won coins cost 77 won. The Bank of Korea designates banknote and coin series in a unique way. Instead of putting those of similar design and issue dates in
SECTION 60
#17328551860945518-661: The notes' most notable features were distinguishable marks for the blind under the watermark and the addition of machine-readable language in preparation for mechanization of cash handling. They were also printed on better-quality cotton pulp to reduce the production costs by extending their circulation life. To cope with the deregulation of imports of color printers and the increasing use of computers and scanners, modified 5,000 and 10,000 won notes were released between 1994 and 2002 with various new security features, which included color-shifting ink, microprint, segmented metal thread, moiré , and EURion constellation . The latest version of
5607-487: The only coins in circulation. New coins, denominated in won, were introduced by the Bank of Korea on August 16, 1966, in denominations of 1, 5 and 10 won, with the 1 won struck in brass and the 5 and 10 won in bronze . These were the first South Korean coins to display the date in the Gregorian calendar , earlier coins having used the Korean calendar . The 10 and 50 hwan coins were demonetized on March 22, 1975. In 1968, as
5696-472: The optimum position tends to grow, requiring sophisticated feedback systems to maintain a constant distance from the track, (approximately 15 millimetres [0.59 in]). The major advantage to suspended maglev systems is that they work at all speeds, unlike electrodynamic systems, which only work at a minimum speed of about 30 kilometres per hour (19 mph). This eliminates the need for a separate low-speed suspension system, and can simplify track layout. On
5785-498: The presence of more urgent economic issues. The Bank of Korea is the only institution in South Korea with the right to print banknotes and mint coins. The banknotes and coins are printed at the KOMSCO, a government-owned corporation, under the guidance of the Bank of Korea. After the new banknotes and coins are minted , they are bundled or rolled and shipped to the headquarters of the Bank of Korea. When delivered, they are deposited inside
5874-494: The project was abandoned. However, from 1999 the "TEMP" research center had been participating as a co-developer in the creation of the linear motors for the Moscow Monorail system. The world's first commercial maglev system was a low-speed maglev shuttle that ran between the airport terminal of Birmingham International Airport and the nearby Birmingham International railway station between 1984 and 1995. Its track length
5963-823: The public imagination, "maglev" often evokes the concept of an elevated monorail track with a linear motor . Maglev systems may be monorail or dual rail—the SCMaglev MLX01 for instance uses a trench-like track—and not all monorail trains are maglevs. Some railway transport systems incorporate linear motors but use electromagnetism only for propulsion , without levitating the vehicle. Such trains have wheels and are not maglevs. Maglev tracks, monorail or not, can also be constructed at grade or underground in tunnels. Conversely, non-maglev tracks, monorail or not, can be elevated or underground too. Some maglev trains do incorporate wheels and function like linear motor-propelled wheeled vehicles at slower speeds but levitate at higher speeds. This
6052-412: The purpose of standardizing the coinage, a new series of 1, 5, 10, 50, and 100 won coins was issued, using the same layout as the 500 won coins, but conserving the coins' old themes. The Bank of Korea announced in early 2006 its intention to redesign the 10 won coin by the end of that year. With the increasing cost of production, then at 38 won per 10 won coin, and rumors that some people had been melting
6141-485: The registration of Bachelet Levitated Railway Syndicate Limited July 9 in London, just weeks before the start of WWI. Bachelet's second related patent, U.S. patent 1,020,943 granted the same day as the first, had the levitation electromagnets in the train and the track was aluminum plate. In the patent he stated that this was a much cheaper construction, but he did not demonstrate it. In 1959, while delayed in traffic on
6230-404: The same happening to the 50 won notes in 1972. Higher-denomination notes of 5,000 and 10,000 won were introduced in 1972 and 1973, respectively. The notes incorporated new security features, including watermark , security thread , and ultraviolet response fibres, and were intaglio printed. The release of 10,000 won notes was planned to be at the same time as the 5,000 won notes, but problems with
6319-495: The same series, it assigns series number X to the Xth design of a given denomination. The series numbers are expressed with Korean letters used in alphabetical order, e.g. 가, 나, 다, 라, 마, 바, 사 . Therefore, 1,000 won issued in 1983 is series II ( 나 ) because it is the second design of all 1,000 won designs since the introduction of the South Korean won in 1962. In 1962, 10 and 50 jeon, 1, 5, 10, 50, 100 and 500 won notes were introduced by
6408-458: The socalled "Hybrid Electromagnetic Suspension (H-EMS)", where the main levitation force is generated by permanent magnets, while the electromagnet controls the air gap, what is called electropermanent magnets . Ideally it would take negligible power to stabilize the suspension and in practice the power requirement is less than it would be if the entire suspension force were provided by electromagnets alone. In electrodynamic suspension (EDS), both
6497-406: The system to its original position. In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed. However, at slow speeds, the current induced in these coils and the resultant magnetic flux is not large enough to levitate the train. For this reason, the train must have wheels or some other form of landing gear to support
6586-494: The train by direct current solenoids spaced along the track. The electromagnetic levitation was due to repulsion of the aluminum base plate of the train by the pulsating current electromagnets under the track. The pulses were generated by Bachelet's own Synchronizing-interrupter U.S. patent 986,039 supplied with 220 VAC. As the train moved it switched power to the section of track that it was on. Bachelet went on to demonstrate his model in London, England in 1914, which resulted in
6675-453: The train until it reaches take-off speed. Since a train may stop at any location, due to equipment problems for instance, the entire track must be able to support both low- and high-speed operation. Another downside is that the EDS system naturally creates a field in the track in front and to the rear of the lift magnets, which acts against the magnets and creates magnetic drag. This is generally only
6764-484: The train, a new design was selected. In Okazaki , Japan (1987), the SCMaglev was used for test rides at the Okazaki exhibition. Tests in Miyazaki continued throughout the 1980s, before transferring to a far longer test track, 20 kilometres (12 mi) long, in Yamanashi in 1997. The track has since been extended to almost 43 kilometres (27 mi). The 603 kilometres per hour (375 mph) world speed record for crewed trains
6853-411: Was 600 metres (2,000 ft), and trains levitated at an altitude of 15 millimetres [0.59 in], levitated by electromagnets, and propelled with linear induction motors. It operated for 11 years and was initially very popular with passengers, but obsolescence problems with the electronic systems made it progressively unreliable as years passed, leading to its closure in 1995. One of the original cars
6942-404: Was awarded U.S. patent 782,312 (14 February 1905) and U.S. patent RE12700 (21 August 1907). In 1907, another early electromagnetic transportation system was developed by F. S. Smith. In 1908, Cleveland mayor Tom L. Johnson filed a patent for a wheel-less "high-speed railway" levitated by an induced magnetic field. Jokingly known as "Greased Lightning," the suspended car operated on
7031-481: Was closed in 1995 due to reliability problems. High-speed transportation patents were granted to various inventors throughout the world. The first relevant patent, U.S. patent 714,851 (2 December 1902), issued to Albert C. Albertson, used magnetic levitation to take part of the weight off of the wheels while using conventional propulsion. Early United States patents for a linear motor propelled train were awarded to German inventor Alfred Zehden . The inventor
7120-626: Was incorporated in the Incheon Airport Maglev which opened on 3 February 2016, making South Korea the world's fourth country to operate its own self-developed maglev after the United Kingdom's Birmingham International Airport, Germany's Berlin M-Bahn , and Japan 's Linimo . It links Incheon International Airport to the Yongyu Station and Leisure Complex on Yeongjong island . It offers
7209-501: Was investigating reviving the Emsland test track. In May 2019 CRRC had unveiled its "CRRC 600" prototype which is designed to reach 600 kilometres per hour (370 mph). In Vancouver, Canada, the HSST-03 by HSST Development Corporation ( Japan Airlines and Sumitomo Corporation ) was exhibited at Expo 86 , and ran on a 400-metre (0.25 mi) test track that provided guests with a ride in
7298-647: Was manufactured by CRRC Qingdao Sifang . Development of the low-to-medium speed systems, that is, 100–200 km/h (62–124 mph), by the CRRC has led to opening lines such as the Changsha Maglev Express in 2016 and the Line S1 in Beijing in 2017. In April 2020 a new model capable of 160 km/h (99 mph) and compatible with the Changsha line completed testing. The vehicle, under development since 2018, has
7387-529: Was one of the first commercial maglev trains since the 1980s. Two more stages were planned of 9.7 km (6.0 mi) and 37.4 km (23.2 mi). Once completed it would have become a circular line. These lines made up a core project that the Korea Rail Network Authority managed. All stations are located in Jung District, Incheon . The maglev train, nicknamed ECOBEE, was co-developed by
7476-543: Was pegged at 125 won = US$ 1 . The following pegs operated between 1962 and 1980: On February 27, 1980, efforts were initiated to lead to a floating exchange rate . The won was finally allowed to float on December 24, 1997, when an agreement was signed with the International Monetary Fund . Shortly after, the won was devalued to almost half of its value, as part of the 1997 Asian financial crisis . Until 1966, 10 and 50 hwan coins, revalued as 1 and 5 won, were
7565-475: Was replaced by the hwan on February 15, 1953, at a rate of 1 hwan = 100 won. In 1946, the Bank of Joseon introduced 10 and 100 won notes. These were followed in 1949 by 5 and 1,000 won notes. A new central bank, the Bank of Korea , was established on June 12, 1950, and assumed the duties of Bank of Joseon. Notes were introduced (some dated 1949) in denominations of 5, 10 and 50 jeon, and 100 and 1,000 won. The 500 won notes were introduced in 1952. In 1953,
7654-482: Was set by the experimental Japanese L0 Series maglev in 2015. From 2002 until 2021, the record for the highest operational speed of a passenger train of 431 kilometres per hour (268 mph) was held by the Shanghai maglev train , which uses German Transrapid technology. The service connects Shanghai Pudong International Airport and the outskirts of central Pudong , Shanghai . At its historical top speed, it covered
7743-636: Was set there in 2015. Development of HSST started in 1974. In Tsukuba , Japan (1985), the HSST-03 ( Linimo ) became popular at the Tsukuba World Exposition , in spite of its low 30 kilometres per hour (19 mph) top speed. In Saitama , Japan (1988), the HSST-04-1 was revealed at the Saitama exhibition in Kumagaya . Its fastest recorded speed was 300 kilometres per hour (190 mph). Construction of
7832-541: Was spent on research. This totals over ₩ 415 billion ( US$ 362.78 million) of taxpayer money spent on the short lived project. During the COVID pandemic the line was reduced to operate during rush hours only, departing Airport Terminal 1 Station every 15 minutes from 07:30 to 09:00 and 18:00-19:00. The reduced service was still operating in May 2022 but was expected to return to full-time service shortly after. At its height in 2019,
7921-527: Was supposed to connect the cities of Yerevan and Sevan via the city of Abovyan . The original design speed was 250 kilometres per hour (160 mph) which was later lowered to 180 kilometres per hour (110 mph). However, the Spitak earthquake in 1988 and the First Nagorno-Karabakh War caused the project to freeze. In the end the overpass was only partially constructed. In the early 1990s,
