Korail Class 8000
The Korail Class 8000 locomotive is a series of South Korean electric locomotives operated by Korail. This locomotive was introduced from 1972 to 1990, after electrification of several industrial lines. It was assigned both passenger and freight duty until the introduction of the 8200 series, which restricted the older locomotives to solely freight service. 94 were built (numbered 8001-8094), but many have been retired as new replacements enter service. Technical details The locomotive was designed by the 50 C/s Group, which consisted of European manufacturers Alsthom (now Alstom), Siemens, MTE, Brown-Boveri, ACEC, and AEG, and was led by Alsthom. The locomotive has three bogies in Bo-Bo-Bo arrangement. With six DC motors, the total power is . The gear ratio is 15:96, and top speed , optimized for mountain lines with steep grades and short radius curves. The design was inspired by contemporary French locomotives, such as SNCF Class BB 15000 and SNCF Class CC 6500. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyeongbu Line
The Gyeongbu Line (''Gyeongbuseon'') is a railway line in South Korea and is considered to be the most important and one of the oldest ones in the country. It was constructed in 1905, connecting Seoul with Busan via Suwon, Daejeon, and Daegu. It is by far the most heavily travelled rail line in South Korea. All types of Korea Train Express, high-speed, express, local, and freight trains provide frequent service along its entire length. History In 1894–1895, the Empire of Japan and Qing Dynasty, Qing China fought the First Sino-Japanese War for influence over Korea. Following the war, Japan competed with the Russian Empire's railway expansion in Northeast Asia, which led it to seek the right from the Korean Empire to build a railway from Busan to Keijō. This railway line was intended by Japan to solidify its strategic positions against Russia, which it would later go to Russo-Japanese War, war. Surveying began in 1896, and in spite of local protests, the Korean Empire gav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown-Boveri
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network.

Railway Locomotives Introduced In 1972
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Electric Locomotives Of South Korea
Electricity is the set of physics, physical Phenomenon, phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing Work (physics), work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an externa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bo-Bo-Bo Locomotives
A Bo-Bo-Bo or Bo′Bo′Bo′ (UIC classification) is a locomotive with three independent two-axle bogies with all axles powered by separate traction motors. In the AAR wheel arrangement, AAR system, this is simplified to AAR wheel arrangement#B-B-B, B-B-B. The Bo-Bo-Bo configuration is often used to lower axle weight while keeping lateral forces low compared to a locomotive with two three-axle bogies, thus allowing the locomotive to use lightly laid track, in particular Narrow gauge railway, narrow-gauge railways. Bo-Bo-Bo locomotives The arrangement is extensively used on Italy, Italian and Japanese railways. Other examples include New Zealand's New Zealand DJ class locomotive, DJ, NZR EW class, EW and New Zealand EF class locomotive, EF classes; the Eurotunnel Class 9 locomotives, which were themselves derived from the New Zealand EF class; the Swiss Swiss Federal Railways, SBB Re 6/6 (Re 620); the Russia Railways VL65, EP1 (electric locomotive), EP1 (EP1M), EP10 and EP20 ...

Taebaek Line
Taebaek Line is a single-track electrified railway mainline connecting Jecheon station to Baeksan station in South Korea. At its two ends, the Taebaek Line connects to the Jungang Line and Yeongdong Line. The line was originally two spur lines, which were built across difficult mountainous terrain in stages, before a connection was built. The line includes the steepest section of the South Korean network, a short parallel line that is operated as a second track on the section includes South Korea's longest spiral tunnel. The centerpiece of the last-built section west of Taebaek, is a tunnel that was the longest in South Korea at the time of its construction, and Chujeon Station at the eastern end of the tunnel is the highest altitude in South Korea at . In passenger traffic, the line is served by cross-country passenger trains connecting the capital Seoul with Korea's east coast. In freight traffic, while coal transport declined, the line carries significant cement transport. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SNCF Class CC 6500
The SNCF Class CC 6500 is a class of 1.5 kV DC electric locomotives. The CC 6500 was, together with the and diesel CC 72000, the first generation of the 'Nez Cassé' family of locomotives and designed for hauling express trains with speeds up to but also used for heavy freight trains. Among the trains they hauled in their first years of service were the SNCF flagship train ''Le Mistral'' and Trans Europ Express trains ''Aquitaine'', '' Le Capitole'' and '' l'Étendard''. Nock, O.S. (1978). "The Aquitaine: pioneer of electric power", in ''World Atlas of Railways'', pp. 120–121. New York: Mayflower Books (original publisher: Artists House, London, UK). . Technical details The locomotives had 3-axle monomotor bogies with each set of 3 axles coupled by gears. Speed regulation was by rheostats and series-parallel control. The motors had double armatures so there were four "demi-motors" which allowed three motor groupings: full series, series-parallel and full parallel. The power co ...

SNCF Class BB 15000
The SNCF class BB 15000 is a class of 25 kV 50 Hz electric locomotives built by Alstom and MTE between 1971 and 1978. Initially 65 locomotives strong, the class was widely deployed on the whole French 25 kV network before being replaced by TGV trains when the LGV Est went into service in 2007. History In the mid-1960s, SNCF sought a new type of dual-current electric locomotives. As thyristor technology advanced rapidly, SNCF decided to adopt the new technology for a new series of locomotives, later known as the '' Nez Cassés'' (Broken Noses, due to their cab styling by Paul Arzens) or BB 4400 kW. Given that the need for pure AC-locomotives was greatest, SNCF placed an initial order of five locomotives in 1968. In 1969 a second order of 10 locomotives followed, in 1970 a third order was made for another 10 locomotives. The remaining 40 locomotives were ordered in 1973. The first five locomotives were delivered in 1971 in the overall-green "Maurienne" livery. The rest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...
