Bo′BoBo′ 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 due to the system only taking powered axles into consideration, not traction axles. 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) ...

Re 6/6
The Re 620, Re 6/6 in the old numbering scheme, are six-axle, electric locomotives of Swiss Federal Railways (SBB CFF FFS), which were acquired as a replacement for the Ae 6/6 for heavy services on the Gotthard Railway. They were produced between 1972 and 1980 and are the most modern of the so-called "Gotthard locomotives". Construction and Technology To reach the necessary tractive effort, a construction comprising six driven axles was necessary. In order to still get good running characteristics in curves, they were built into three two-axle bogies instead of two three-axle bogies as on the Ae 6/6. The middle bogie can move sideways, and the three bogies are connected by elastic cross couplings. Two of the four prototypes (11601, 11602) were built with a split locomotive body, whereby the joint may only move on an horizontal transverse axis to allow for changes in gradient, similar to the Rhaetian Railway Ge 6/6 II. The other two prototypes (11603, 11604) got a softer sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

State Rail Authority
The State Rail Authority, a former statutory authority of the Government of New South Wales, operated and maintained railways in the Australian state of New South Wales from July 1980 until December 2003. History The ''Transport Authorities Act 1980'' separated the functions of the Public Transport Commission (formerly responsible for all public transport) and established the State Rail Authority. The State Rail Authority assumed responsibility for trains, while the Urban Transit Authority responsibility for buses and ferries. In July 1982 a new colour scheme developed by Phil Belbin of red, yellow, orange and white was unveiled, which was commonly referred to as the "candy colours". The ''L7'' logo used by the Public Transport Commission was retained, albeit with the dark and light blue replaced with red and orange. Around this time, they also gave playing cards and soap to passengers. Electrification During its tenure the State Rail Authority completed a number of electr ...

Myanmar Railways
Rail transport in Myanmar consists of a railway network with 960 stations. The network, generally spanning north to south with branch lines to the east and west, is the second largest in Southeast Asia, and includes the Yangon Circular Railway which serves as a commuter railway for Yangon, the principal commercial city in Myanmar. The quality of the railway infrastructure is generally poor. The tracks are in poor condition, and are not passable during the monsoon season. The speed of freight trains is heavily restricted on all existing links as a consequence of poor track and bridge conditions. The maximum speed for freight trains has been quoted as , suggesting that commercial speeds on this section could be as low as . The network is run by Myanma Railways (, ; formerly Burma Railways), a state-owned railway company under the Ministry of Rail Transportation. In the 2013-14 fiscal year, Myanma Railways carried about 60 million passengers (35 million in the circular railway an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Railways Class SS7
The Shaoshan 7 () is a type of electric locomotive used on the People's Republic of China's national railway system. They are widely used on electrified lines in the southwest part of China. Design The design of SS7 was influenced by the China Railways 6K, 6K, an electric locomotive model imported from Japan.SS7型电力机车 _trainnets.com The first SS7 was built in 1992 in Datong. In 1997, SS7s were used in Nanning-Kunming Railway. However, SS7's frequent failure lead to Datong Electric Locomotive Works making improvements to SS7s. Failure was reduced to just four cases in one year in 2004. SS7 Electric Locomotive was still produced as of 2007. Most of SS7s belong to Liuzhou Locomotive Depot, Nanning Railway Bureau. The last two SS7s (8112 and 8113) belong to Xiaoyi-Liulin Railway, which is located in Shanxi. Derivatives |
Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a Battery (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Railways Class 6K
The 6K is a Japanese-built electric locomotive used in China. It is developed and built by Kawasaki Heavy Industries and Mitsubishi Electric.

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 Korail Electric Locomotive 8200, 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- Hertz Group, which consisted of European manufacturers Alstom, Siemens Mobility, Siemens, MTE, Brown, Boveri & Cie, Ateliers de Constructions Electriques de Charleroi, ACEC, and AEG (German company), AEG, and was led by Alstom. The locomotive has three bogies in Bo-Bo-Bo arrangement. With six DC motors, the total power is .

EP20
An extended play (EP) is a musical recording that contains more tracks than a single but fewer than an album. Contemporary EPs generally contain up to eight tracks and have a playing time of 15 to 30 minutes. An EP is usually less cohesive than an album and more "non-committal". An extended play (EP) originally referred to a specific type of 45 rpm phonograph record other than 78 rpm standard play (SP) and 33 rpm long play (LP), but , also applies to mid-length CDs and downloads. EPs are considered "less expensive and less time-consuming" for an artist to produce than an album, and have long been popular with punk and indie bands. In K-pop and J-pop, they are usually referred to as mini-albums. Background History EPs were released in various sizes in different eras. The earliest multi-track records, issued around 1919 by Grey Gull Records, were vertically cut 78 rpm discs known as "2-in-1" records. These had finer grooves than usual, like Edison Disc Records.
