JNR Class DE11
The is a five-axle C-B wheel arrangement diesel-hydraulic shunting locomotive type operated in Japan since 1968. A total of 116 locomotives were built between 1968 and 1979, and , 10 locomotives remain in service, operated by East Japan Railway Company (JR East) and Japan Freight Railway Company (JR Freight). Variants A total of 116 locomotives were built between 1968 and 1979, divided into the following sub-classes. * Class DE11-0: 65 locomotives built between 1968 and 1970 * Class DE11-1000: 46 locomotives built between 1970 and 1974 with uprated engines * Class DE11-1900: One locomotive built in 1975 with experimental noise-reduction features * Class DE11-2000: 4 locomotives built in 1979 with noise-reduction features Design The Class DE11 was developed from the Class DE10 locomotive design, with the train-heating steam generator and multiple-working equipment removed and replaced with concrete ballast weight to increase the axle load from 13 t to 14 t to improve adhesion f ...

Class DE10
The is a class of Japanese C-B wheel arrangement diesel-hydraulic locomotives. 708 locomotives were built between 1966 and 1978. , 138 locomotives remained in operation. Variants DE10-0 subclass 158 DE10-0 locomotives were built with steam generator (railroad), steam heating boilers for passenger use. None of this subclass remains in use on JR, but several examples operate on private railways. DE10 1 is preserved at JR Shikoku's Tadotsu depot. DE10-500 subclass 74 DE10-500 locomotives were built from 1968 with concrete ballast in place of the steam heating boilers for freight use. None of this subclass remains in use on JR, but several examples operate on private railways. DE10-900 subclass One prototype locomotive, DE10 901, was built in 1967 as a heavy shunting locomotive with ballasting increasing the weight to 70 tonnes. This formed the basis for the Class DE11 design. DE10-1000 subclass 210 DE10-1000 locomotives were built from 1969 with steam heating boilers and uprat ...

Railway Locomotives Introduced In 1968
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 Track (rail transport), 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 Railroad tie, sleepers (ties) set in track ballast, 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 friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ...

1067 Mm Gauge Locomotives Of Japan
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by  2, although by other definitions 1 is the second natural number, following  0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ...

C-B Locomotives
Co-Bo or Co′Bo′ is a wheel arrangement in the UIC classification system for railway locomotives. It features two uncoupled bogies. The "Co" bogie has three driven axles and the "Bo" bogie has two. The arrangement has been used to even out axle loading. The weight distribution of the locomotive depends on the power unit, the engine and generator. If these are not placed symmetrically, the weight distribution is also biased to one end. Placing three axles beneath the engine end and just two beneath the other, with the lighter ancillaries, gives more even loading per-axle. Examples Diesel The British Railways Class 28 is the first (and only) UK locomotive with a Co-Bo wheel arrangement. C-B A similar wheel arrangement, with five axles across two bogies, is also used in Japan for the Class DE10, DE11, and DE15 locomotives. As these are diesel-hydraulic locomotives, they are of C-B arrangement, not Co-Bo. A hydrodynamic transmission on the locomotive frame is driven by the ...

Axle Load
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a ''spindle''. Terminology On cars and trucks, several senses of the word ''axle'' occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an ''axle'' or ''axle shaft''. However, in looser usage, an entire assembly including the surrounding axle housing (typically a casting) is als ...

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 ...

It was a listed company on Nikkei 225 until 2004. It is listed on the Tokyo Stock Exchange and Nagoya Stock Exchange as ticker 7102. In 2008, Central Japan Railway Company (JR Central) became the majority shareholder (50.1%) of the financially struggling Nippon Sharyo making the firm a "consolidated subsidiary" of JR Central. In July 2012 Nippon Sharyo USA started production in their new facility in Rochelle, Illinois. The facility closed at the end of October 2018 due to a lack of orders.

Switcher
A switcher, shunter, yard pilot, switch engine, yard goat, or shifter is a small railroad locomotive used for manoeuvring railroad cars inside a rail yard in a process known as ''switching'' (US) or ''shunting'' (UK). Switchers are not intended for moving trains over long distances but rather for assembling trains in order for another locomotive to take over. They do this in classification yards (Great Britain: ''marshalling yards''). Switchers may also make short transfer runs and even be the only motive power on branch lines and switching and terminal railroads. The term can also be used to describe the workers operating these engines or engaged in directing shunting operations. Switching locomotives may be purpose-built engines, but may also be downgraded main-line engines, or simply main-line engines assigned to switching. Switchers can also be used on short excursion train rides. The typical switcher is optimised for its job, being relatively low-powered but with a high ...
