Japan Railways Locomotive Numbering And Classification
This page explains the numbering and classification schemes for locomotives employed by the Japanese Government Railways, the Japanese National Railways and the Japan Railways Group. Steam locomotives Pre-nationalization Prior to the nationalization of Japanese railways in 1906 and 1907, the government-run railways had numbered their steam locomotives only with serial numbers without consideration of the types of the locomotives. From the beginning of the Kobe–Osaka railway in 1874, they allocated odd numbers to locomotives in Tokyo area and even numbers to locomotives in Kobe area, but this custom was not maintained after the completion of railway between Tokyo and Kobe in 1889. Later, some locomotives, such as Classes A8 and B6 and rack railway locomotives, were renumbered to make groups for easy recognition of classes. Classes were introduced by Francis H. Trevithick (1850–1931), a grandson of Richard Trevithick, employed by the government of Japan for supervision of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, Motor coach (rail), motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, Push-pull train, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

JNR Class D51
The is a type of 2-8-2 steam locomotive built by the Japanese Government Railways (JGR), the Japanese National Railways (JNR), and Kawasaki Heavy Industries Rolling Stock Company, Kisha Seizo, Hitachi, Nippon Sharyo, Mitsubishi, and Mitsubishi Heavy Industries from 1936 to 1945 and 1950 to 1951. Design and operation The design of class D51 was based on the earlier D50, introduced in 1923. Wartime production featured some substitution of wood for steel parts like running boards, smoke deflectors and tender coal bunkers. A total of 1,115 D51s were built, the largest number in any single class of locomotive in Japan. Early D51s were nicknamed ''Namekuji-gata'' ("slug-form") for their shape. The locomotive was designed by Hideo Shima. It was used mainly in freight service through the 1960s. Some D51s were fitted with the Giesl ejector in Hokkaido to conserve on fuel. Service outside Japan Soviet Railways D51 The specially 30 built D51s that were left on Sakhalin (formerly Karafuto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

East Japan Railway Company
The is a major passenger railway company in Japan and is the largest of the seven Japan Railways Group companies. The company name is officially abbreviated as JR-EAST or JR East in English, and as in Japanese. The company's headquarters are in Yoyogi, Shibuya, Tokyo, and next to the Shinjuku Station. It is listed in the Tokyo Stock Exchange (it formerly had secondary listings in the Nagoya Stock Exchange, Nagoya and Osaka Exchange, Osaka stock exchanges), is a constituent of the TOPIX Large70 index, and is also one of the three only Japan Railways Group constituents of the Nikkei 225 index, the other being Central Japan Railway Company, JR Central and West Japan Railway Company, JR West. History JR East was incorporated on 1 April 1987 after being spun off from the government-run Japanese National Railways (JNR). The spin-off was nominally "privatization", as the company was actually a wholly owned subsidiary of the government-owned Japanese National Railway Settlement ...

JR Freight Class EF200
The was a Bo-Bo-Bo wheel arrangement DC electric locomotive operated by JR Freight on freight services in Japan from 1992 until its retirement on 28 March 2019. Overview The Class EF200 was developed to replace Class EF66 electric locomotives on heavy freight services on the Tokaido Main Line and Sanyo Main Line west of Tokyo. It is equipped with six FMT2 traction motors, giving a total power output of . Ultimately, the class was deemed to be over-specified and unnecessarily expensive, and the order was terminated after the delivery of 20 full-production locomotives. The subsequent Class EF210 was instead chosen as the standard design for hauling freight services on the Tokaido Main Line and Sanyo Main Line. Originally designed to haul freight trains, problems of insufficient power supply capacity to the overhead lines, meant that the class was initially limited to hauling trains. Operations , the fleet consists of 12 locomotives (EF200-2 – 7, 10, 15, and 17 – 20), b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Freight Railway Company
, or , is one of the seven constituent companies of Japan Railways Group (JR Group). It provides transportation of cargo nationwide throughout Japan. Its headquarters are in Shibuya, Tokyo near Shinjuku Station. The Japan Railways Group was founded on 1 April 1987, when Japanese National Railways (JNR) was privatized. Japanese National Railways was divided into six regional passenger rail companies and a single freight railway company, Japan Freight Railway Company. The company has only about of track of its own, and therefore operates on track owned by the six JR passenger railways as well as other companies which provide rail transport in Japan. Economics In 2017, only about 5% of all freight in Japan is carried by rail but nearly all of that, 99%, is carried by JR Freight. Trucks carry about 50% and ships about 44%. JR Freight has seen its share of the freight market gradually decrease since 1993. In the 2010s JR Freight has been carrying more freight because of the dec ...

These were also subsequently retro-fitted to locomotives EF81 133 to 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

JNR Class ED10
The was a Bo-Bo wheel arrangement electric locomotive that operated in Japan from 1922. The two locomotives in the class were designed and built by Westinghouse Electric (electrical components) and Baldwin (mechanical components) in 1922. Originally designated "Class 1000", the locomotives were reclassified ED10 in 1928. The unit has a Bo-Bo wheel arrangement and is powered by four DC traction motors producing a total of 1,100 horsepower. The ED10 weighs just over 67 tons and has a top speed of . Preserved examples Following its withdrawal in 1960, ED10 2 was sold to the Seibu Railway, where it became number E71. It was operated until 1986, after which it was preserved at Yokoze Depot and returned to its original JNR-era livery.
