Seoul Metro 2000 Series (2005)
The second-generation Seoul Metro 2000-series is a South Korean electrical multiple unit train manufactured by Hyundai Rotem and Dawonsys since 2005 for Seoul Metro, operating on Seoul Subway Line 2. History In 2004, Seoul Metro ordered a first batch comprising 5 ten-car trains (2-01~2-05) and 1 four-car unit (2-57) from Hyundai Rotem. The trains were delivered in 2005 and replaced aging 1st generation 2000-series trains. In 2006, Seoul Metro ordered a second batch comprising 29 ten-car trains (2-15~2-31 and 2-61~2-72) and three four-car trains (2-58~2-60) from Hyundai Rotem. The trains were delivered from 2007 to 2008 and replaced aging 1st generation 2000-series trains. Trains 2-23~2-31 and 2-71~2-72 use newer unpowered 1st generation 2000-series cars built between 1991 and 1992, which were retrofitted with technology found in the newer trains. In 2015, Seoul Metro ordered a third batch comprising 20 ten-car trains (2-06~2-13, 2-39~2-42, 2-85~2-92) from Dawonsys. The design ...

Hyundai Rotem
Hyundai Rotem (founded in 1977) is a South Korean company that manufactures rolling stock, defense products and plant equipment. It is a part of the Hyundai Motor Group. Its name was changed from Rotem to Hyundai Rotem in December 2007 to reflect the parent company. History The company was founded in 1977. In 1999, the company changed its name to Korea Rolling Stock Corporation (KOROS) as a result of the merging between three major rolling stock divisions: Hanjin Heavy Industries, Daewoo Heavy Industries and Hyundai Precision & Industries. The company subsequently changed its name to Railroading Technology System, or Rotem, on 1 January 2002. It adopted its current name in December 2007 to reflect its current owner. Hyundai Rotem currently employs 3,800 people and exports to 50 countries worldwide. Railway products Notable projects include supplying most of South Korea's rolling stock, which include Korail's KTX high speed trains, electric multiple units (EMUs), and elect ...

Regenerative Brake
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...

Rolling Stock Of South Korea
Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as ''pure rolling''. By definition, there is no sliding when there is a frame of reference in which all points of contact on the rolling object have the same velocity as their counterparts on the surface on which the object rolls; in particular, for a frame of reference in which the rolling plane is at rest (see animation), the instantaneous velocity of all the points of contact (e.g., a generating line segment of a cylinder) of the rolling object is zero. In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Nevertheless, the resulting rolling resistance is much lower than sliding friction, and thus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seoul Metropolitan Subway
The Seoul Metropolitan Subway is a metropolitan railway system consisting of 23 rapid transit, light metro, commuter rail and people mover lines located in northwest South Korea. The system serves most of the Seoul Metropolitan Area including the Incheon metropolis and satellite cities in Gyeonggi province. Some regional lines in the network stretch out beyond the Seoul Metropolitan Area to rural areas in northern Chungnam province and western Gangwon province, that lie over 100 km away from the capital. The network consists of multiple systems that form a larger, coherent system. These being the Seoul Metro proper, consisting of Seoul Metro lines 1 through 9 and certain light rail lines, that serves Seoul city proper and its surroundings; Korail regional rail lines, which serve the greater metropolitan region and beyond; Incheon Metro lines, operated by Incheon Transit Corporation, that serve Incheon city proper; and miscellaneous light rail lines, such as Gimpo Gol ...

Rail Transport In South Korea
Rail transport in South Korea is a part of the transport network in South Korea and an important mode of the conveyance of people and goods, though railways play a secondary role compared to the road network. The network consists of of standard-gauge lines connecting all major cities with the exception of Jeju City on Jeju Island, which does not have railways; of the network, are double-tracked and are electrified. In 2018, rails carried 11.5 percent of all traffic in South Korea134.8million passengers and 30.9milliontonnes of freightwith roads carrying 88.3 percent. Passenger and freight services are primarily provided by the Korea Railroad Corporation, branded as Korail, a state-owned enterprise under the Ministry of Land, Infrastructure and Transport, although some rail lines and services, including high-speed intercity rails and metropolitan rapid transit, are operated by private companies. The Korea National Railway (formerly the Korea Rail Network Authority), anoth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guro Digital Complex Station

Yonhap News Agency
Yonhap News Agency is a major South Korean news agency. It is based in Seoul, South Korea. Yonhap provides news articles, pictures and other information to newspapers, TV networks and other media in South Korea. History Yonhap (, , translit. ''Yeonhap''; meaning "united" in Korean) was established on 19 December 1980, through the merger of Hapdong News Agency and Orient Press. The Hapdong News Agency itself emerged in late 1945 out of the short-lived Kukje News, which had operated for two months out of the office of the Domei, the former Japanese news agency that had functioned in Korea during the Japanese colonial era. In 1999 Yonhap took over the Naewoe News Agency. Naewoe was a South Korea government-affiliated organization, created in the mid 1970s, and tasked with publishing information and analysis on North Korea from a South Korean perspective through books and journals. Naewoe was known to have close links with South Korea's intelligence agency, and according to the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ex ...
