Škoda Type 22E2
The Škoda Type 22E2 type locomotive is a multipurpose electric locomotive built for the North Korean State Railway by the Škoda Works of Czechoslovakia. Description ČD Class 140, a class of very similar locomotives off of which the 22E2 was based Although some lines had been electrified already in the colonial era, the large-scale electrification of North Korea's railways began in 1956 after the end of the Korean War and the subsequent reconstruction of North Korea's railway infrastructure. To work the newly electrified lines, an order was placed with the Škoda Works in Czechoslovakia for electric locomotives of works Type 22E2, based on the Type 12E locomotives built by Škoda for the Czechoslovak State Railways (ČSD class E 499.0). The Type 12E was developed by Škoda Works based on the technology of the BLS Class Ae 4/4 built by SLM Winterthur. The first prototype was completed in 1953, and production of types 12E1—12E6 continued until 1958 for the ČSD and the Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Škoda Works
The Škoda Works (, ) was one of the largest European industrial conglomerates of the 20th century. In 1859, Czech engineer Emil Škoda bought a foundry and machine factory in Plzeň, Bohemia, Austria-Hungary that had been established ten years previously, founding Škoda Works. By World War I, Škoda Works had become the largest arms manufacturer in Austria-Hungary, supplying the Austro-Hungarian army with mountain guns, mortars and machine guns, including the Škoda M1909, and the ships of the Austro-Hungarian navy with heavy guns. After the war and the creation of the First Czechoslovak Republic, the company, previously focusing on the manufacturing of armaments, diversified and became a major manufacturer of locomotives, aircraft, ships, machine tools, steam turbines, equipment for power utilities, among other industrial products. The deteriorating political situation in Europe by the latter half of the interwar period eventually led to a renewed focus on armament ...

3000 V DC Locomotives
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Chongnyonjol Kinyom-class Locomotive
The Ch'ŏngnyŏnjŏl Kinyŏm-class (, "Youth Day Memorial") is composed of two groups of Bo-Bo electric locomotives operated by the Korean State Railway on passenger and freight trains throughout North Korea. In 1981, the Korean State Railway took delivery of seven Francorail, Francorail-MTE Francorail-MTE CSE26-21, CSE26-21 diesel locomotives from France, followed by five more in 1985. Due to oil shortages in the late 1980s and early 1990s, it was decided to convert these locomotives to 3,000 V DC electric operation, by removing the diesel engines and installing Pantograph (transport), pantographs and other necessary electrical equipment; this work was carried out by the Kim Chong-t'ae Electric Locomotive Works in Pyongyang, P'yŏngyang. The result of this were the prototypes of the Red Flag 5400-class locomotive, 5400-series Red Flag Co-Co locomotives. The Ch'ŏngnyŏnjŏl Kinyŏm-class locomotives have a body and chassis design derived from that of the CSE26-21, but other comp ...

Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, or electric multiple unit trains. Traction (engineering), Traction motors are used in electrically powered railway vehicles (electric multiple units) and other electric vehicles including electric milk floats, trolleybuses, elevators, roller coasters, and conveyor systems, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel–electric locomotives, electric hybrid vehicles), and battery electric vehicles. Traction motor companies The word ''traction'' from Latin, being the Agent (grammar), agent noun of ''trahere'' "to pull" in the sense of "drawn" was used for the naming of traction engines developed circa 1870. The first experimental electric traction motor tramway of 1875 was rapidly developed internationally for city use. In the 19th century traction motor passenger car companies ...

Bogies
A bogie ( ) (or truck in North American English) comprises two or more wheelsets (two wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly in a road train or in railway bogie exchange). It may include suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. Railway A ''bogie'' in the UK, or a ''railroad truck'', ''wheel truck'', or simply ''truck'' in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...

Polish State Railways
The Polish State Railways ( , abbr.: PKP S.A.) is a Polish state-owned holding company (legally a sole-shareholder company of the State Treasury) comprising the rail transport holdings of the country's formerly dominant namesake railway operator. The company was reformed in 2001 when the former Polish State Railways state-owned enterprise was divided into several units based on the need for separation between infrastructure management and transport operations. Polish State Railways is the dominant company in the PKP Group collective that resulted from the split, and maintains 100% share control, being fully responsible for the assets of all of the other PKP Group component companies. PKP today PKP is currently the parent company of the PKP Group, passenger operators PKP Intercity and PKP Szybka Kolej Miejska w Trójmieście.

Swiss Locomotive And Machine Works
Swiss Locomotive and Machine Works (German Schweizerische Lokomotiv- und Maschinenfabrik; French Société Suisse pour la Construction de Locomotives et de Machines; or for both, SLM) was a railway equipment manufacturer based in Winterthur in Switzerland. Much of the world's mountain railway equipment was constructed by the company. History The company was founded in 1871 by the British engineer Charles Brown (British engineer), Charles Brown. SLM built both steam locomotive, steam and electric locomotives, including the Crocodile (locomotive), crocodile type. From 1992, SLM returned to producing steam locomotives designed around advanced steam technology principles. This included rebuilding DR Class 52.80 locomotive number 52 8055. In 1998, the cog-railway division was sold to Stadler Rail, and the engineering division, via Adtranz, to Bombardier Transportation.
