Fastech 360
Fastech 360 is the name given to a pair of former experimental high-speed EMU trainsets developed by East Japan Railway Company (JR East) to test technology for the next-generation Shinkansen rolling stock. The name is a portmanteau of Fast, Technology, and 360 km/h (), the target operational speed for production trains based on the new technologies. Speeds of up to were targeted during performance testing. Results of testing using these trains was incorporated into the E5 series and E6 series trains, entering revenue service from 2011, eventually operating at . There were 2 trains: *Class E954 ''Fastech 360S'': 8-car set for use on shinkansen tracks only *Class E955 ''Fastech 360Z'': 6-car set for use on both shinkansen and Mini-shinkansen lines Fastech 360 trains were equipped with emergency air braking plates like that of an aircraft, similar in appearance to the ears of a cat. This trait earned them a nickname of , which literally means "cat-eared Shinkansen". This techno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

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 ...

25 KV AC Multiple Units
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3p ...

Experimental And Prototype High-speed Trains
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into Causality, cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experiment, natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shinkansen Train Series
The , colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies. Over the Shinkansen's 50-plus-year history, carrying over 10 billion passengers, there has been not a single passenger fatality or injury on board due to derailments or collisions. Starting with the Tokaido Shinkansen () in 1964, the network has expanded to currently consist of of lines with maximum speeds of , of Mini-Shinkansen lines with a maximum speed of , and of spur lines with Shinkansen services. The network presently links most major cities on the islands of Honshu and Kyushu, and Hakodate on northern island of Hokkaido, with an extension to Sapporo under constru ...

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

E4 Series
The was a high-speed shinkansen train type operated by East Japan Railway Company (JR East) in Japan. They were the second series of completely bi-level Shinkansen trainsets to be built in Japan (the other being the E1 series). They previously operated on the Tōhoku and Jōetsu Shinkansen, and occasionally on the Nagano Shinkansen. E4 series trains feature double-decker cars to accommodate additional commuter traffic around Tokyo and other urban areas. They were often coupled to 400 series trains on the Tōhoku Shinkansen between Tokyo and Fukushima before the latter retired in April 2010. The last trains of the E4 series were withdrawn from regular service on 1 October 2021. Two eight-car sets can be coupled together for extra capacity: a sixteen-car E4 series formation trainset carries a total of 1,634 seated passengers, the highest-capacity high-speed rail trainset in the world. 26 units were built between 1997 and 2003. As with the earlier E1 series trains, maximum spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

500 Series Shinkansen
The is a Shinkansen high-speed train type operated by West Japan Railway Company (JR-West) on the Tōkaidō Shinkansen and San'yō Shinkansen lines in Japan since 1997. They were designed to be capable of but operated at , until they were finally retired from the primary '' Nozomi'' service in 2010. The trainsets were then refurbished and downgraded to the all-stations '' Kodama'' service between and . Overview The general design concept was overseen by German industrial designer Alexander Neumeister. The running gear utilizes computer-controlled active suspension for a smoother, safer ride, and yaw dampers are fitted between cars for improved stability. All sixteen cars in each original trainset were powered, giving a maximum of . Each train cost an estimated 5 billion yen, and only nine were built. It used biomimicry to reduce energy consumption by 15%, increase speeds by 10% and reduce noise levels while increasing passenger comfort. This was done by making the train's fr ...
