SCMaglev
The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation (maglev) railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research Institute. On 21 April 2015, a manned seven-car L0 Series SCMaglev train reached a speed of , less than a week after the same train clocked , breaking the previous land speed record for rail vehicles of set by a JR Central MLX01 maglev train in December 2003. Technology The SCMaglev system uses an electrodynamic suspension (EDS) system. The trains' bogies have superconducting magnets installed, and the guideways contain two sets of metal coils. The current levitation system utilizes a series of coils wound into a "figure 8" along both walls of the guideway. These coils are also cross-connected underneath the track. As the train accelerates, the magnetic fields of its superconducting magnets induce a current into these coils due to the magnetic field induction effect. If th ...

Shinkansen
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 ...

Gauge Change Train
The Gauge Change Train (GCT) or is the name given to a Japanese project started in 1994 to develop a high-speed train with variable gauge axles to allow inter-running between the Shinkansen network, and the narrow gauge regional rail network. Two three-car and one four-car "GCT" electric multiple unit (EMU) trains have been built for testing. The first train operated from 1998 until 2006, the second train operated from 2006 until 2014 and the third-generation train commenced testing in 2014, although testing is currently suspended due to technical issues with the bogies. The GCT was due to be introduced on the Nagasaki Shinkansen upon its scheduled opening in fiscal 2022, but JR Kyushu announced in June 2017 that it had abandoned plans to adopt the GCT for these services. First-generation train (1998–2006) The first GCT train was completed in October 1998. It was designed to be able to run at a maximum speed of over on Shinkansen lines, and at over on conventional narr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Gauge
A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges. For through operation, a train must be equipped with special bogies holding variable gauge wheelsets containing a variable gauge axle (VGA). The gauge is altered by driving the train through a gauge changer or gauge changing facility. In effect, the track widens or narrows. As the train passes through the gauge changer, the wheels are unlocked, are moved closer together, or further apart, and are then re-locked. Installed variable gauge systems exist within the internal network of Spain, and are installed on international links between Spain/France (Spanish train), Sweden/Finland (Swedish train), Poland/Lithuania (Polish train) and Poland/Ukraine (Polish train). A system for changing gauge without the need to stop is in widespread use for passenger traffic in Spain, for services run on a mix of dedicated high-speed lines (using St ...

Maglev
Maglev (derived from '' magnetic levitation''), is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction. Such trains rise approximately off the track. There are both high speed, intercity maglev systems (over ), and low speed, urban maglev systems ( to ) being built and under construction and development. With maglev technology, the train travels along a guideway of electromagnets which control the train's stability and speed. While the propulsion and levitation require no moving parts, the bogies can move in relation to the main body of the vehicle and some technologies require support by retractable wheels at low speeds under . This compares with electric multiple units that may have several dozen parts per bogie. Maglev trains can therefore in some cases be quieter and smoother than conventional trains and have t ...

Japan Railways
The Japan Railways Group, more commonly known as the or simply JR, consists of seven for-profit stock companies that took over most of the assets and operations of the government-owned Japanese National Railways (JNR) on April 1, 1987. Most of the liability of the JNR was assumed by the JNR Settlement Corporation. The JR Group lies at the heart of Japan's railway network, operating a large proportion of intercity rail service (including the Shinkansen high-speed rail lines) and commuter rail service. JR Hokkaido, JR Shikoku, and JR Freight (JRF) are governed by the , also known as the ''JR Companies Act'', and are under the control of the public Japan Railway Construction, Transport and Technology Agency (JRTT), while JR East, JR Central, JR West, and JR Kyushu have full private ownership. Because the railways used to be owned by the government, Japanese people generally make a distinction between JR railways (including former JR lines that are now third sector) and ot ...

Rail Transport In Japan
Rail transport in Japan is a major means of passenger transport, especially for mass and high-speed travel between major cities and for commuter transport in urban areas. It is used relatively little for freight transport, accounting for just 0.84% of goods movement. The privatised network is highly efficient, requiring few subsidies and running with extreme punctuality. Overview Rail transport services in Japan are provided by more than 100 private companies, including * Six Japan Railways Group (JR) regional companies (state owned until 1987) which provide passenger services to most parts of Hokkaido, Honshu, Shikoku, and Kyushu; * The nationwide JR freight company; and * 16 major regional companies which provide railway services as part of their corporate operations. There are also dozens of smaller local private railways. Many of the private rail companies rank among the top corporations in the country. Railways were built by private corporations developing integrated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrail
In transportation, hydrail is the generic term describing all forms of rail vehicles, large or small, which use on-board hydrogen fuel as a source of energy to power the traction motors, or the auxiliaries, or both. Hydrail vehicles use the chemical energy of hydrogen for propulsion, either by burning hydrogen in a hydrogen internal combustion engine, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling rail transportation is a basic element of the proposed hydrogen economy. The term has been used by research scholars and technicians around the world. Hydrail vehicles are usually hybrid vehicles with renewable energy storage, such as batteries or super capacitors, for regenerative braking, improving efficiency and lowering the amount of hydrogen storage required. Potential hydrail applications include all types of rail transport: commuter rail; passenger rail; freight rail; light rail; rail rapid transit; mine railw ...
