Japan Transport Engineering Company
–
Japan Transport Engineering Company is a manufacturer of heavy rail cars in Japan, formerly known as Tokyu Car Corporation. The company is based in Kanazawa-ku, Yokohama, and a member of East Japan Railway Company group, J-TREC manufactures rail vehicles not only for JR East and Tokyu Corporation but for other Japanese operators, including various Japan Railways Group companies and international operators as well. Tokyu Car Corporation, the root of J-TREC, was founded on 23 August 1948, Tokyu Car was a licensee of early-generation stainless-steel commuter EMU train body and related bogie technology from the Budd Company of the United States. Since then, Tokyu Car has specialised in stainless-steel body car technology and it is to be subsequently split into two companies, Tokyu Car Engineering and Keihin Steel Works. Both companies will be subsidiaries of JR East, the remaining parts and machinery manufacturing division will be sold to ShinMaywa Industries. On 2 April 2012, divisions were sold and renamed, with Mitsui Iarnród Éireann/Irish Rail InterCity fleet replacement. Tokyu Car was the supplier for a fleet of high specialist 22000 Class DMUs capable of 160 km/h operation. Coaches were built by Rotem and specialist diesel-hydraulic power packs were built by MTU Friedrichshafen, Japan, Kōyūsha Co. Ltd. pp. 110–113.

Tokyo Metro
–
Tokyo Metro Co. Ltd. commonly known as Tokyo Metro, is a rapid transit system in Tokyo, Japan. The company replaced the Teito Rapid Transit Authority, commonly known as Eidan or TRTA, Tokyo Metro is operated by Tokyo Metro Co. Ltd. a private company jointly owned by the Japanese government and the Tokyo metropolitan government. The company replaced the Teito Rapid Transit Authority, commonly known as Eidan or TRTA, TRTA was administered by the Ministry of Land, Infrastructure and Transport, and jointly funded by the national and metropolitan governments. It was formed in 1941, although its oldest lines date back to 1927 with the opening of the Tokyo Underground Railway the same year, the other major subway operator is Tokyo Metropolitan Bureau of Transportation which is owned solely by the government of Tokyo. Tokyo Metro and Toei trains form completely separate networks, though, most Tokyo Metro line offer through service to lines outside of central Tokyo run by other carriers, and this can somewhat complicate the ticketing. Much effort has made to make the system accessible to non-Japanese speaking users. Announcements also provide connecting line information, ticket machines can switch between English and Japanese user interfaces. Train stations are signposted in English and Japanese, there are also numerous signs in Chinese and Korean. Train stations are now also numbered on each color-coded line. In addition, some trains have interior LCD displays which display station names in Japanese, English, Chinese, Many stations are also designed to help blind people as railings often have Braille at their base, and raised yellow rubber guide strips are used on flooring throughout the network. Tokyo Metro stations began accepting contactless Pasmo stored value cards in March 2007 to pay fares, both these passes also can be used on surrounding rail systems throughout the area and many rail lines in other areas of Japan. Due to the complexity of the systems in Japan, most riders converted to these cards very quickly even though there is an additional charge to be issued a card. The Tokyo Metro is extremely punctual and has trains arriving less than five minutes apart most of the day. However, it not run 24 hours a day. While through service with other companies complicates this somewhat, the last train generally starts at midnight and completes its service by 01,00, Tokyo Metro indicated in its public share offering that it would cease line construction once the Fukutoshin Line was completed. That line was completed in March 2013 with the opening of the connection with the Tōkyū Tōyoko Line at Shibuya Station, allowing through service as far as Motomachi-Chūkagai Station in Yokohama. There are several such as the Hanzōmon Line that still have extensions in their official plans, and in the past. There are also some other rail project proposals in Tokyo which would involve large-scale tunneling projects and this line is often described as a bypass of the current Toei Asakusa Line

Railway electrification system
–
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure, selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas, some electric locomotives can switch to different supply voltages to allow flexibility in operation, Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network, some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own lines, switches and transformers. Power is supplied to moving trains with a continuous conductor running along the track usually takes one of two forms. The first is a line or catenary wire suspended from poles or towers along the track or from structure or tunnel ceilings. Locomotives or multiple units pick up power from the wire with pantographs on their roofs that press a conductive strip against it with a spring or air pressure. Examples are described later in this article, the second is a third rail mounted at track level and contacted by a sliding pickup shoe. Both overhead wire and third-rail systems usually use the rails as the return conductor. In comparison to the alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions. Electric locomotives are usually quieter, more powerful, and more responsive and they have no local emissions, an important advantage in tunnels and urban areas. Different regions may use different supply voltages and frequencies, complicating through service, the limited clearances available under catenaries may preclude efficient double-stack container service. Possible lethal electric current due to risk of contact with high-voltage contact wires, overhead wires are safer than third rails, but they are often considered unsightly. These are independent of the system used, so that. The permissible range of voltages allowed for the voltages is as stated in standards BS EN50163. These take into account the number of trains drawing current and their distance from the substation, railways must operate at variable speeds. Until the mid 1980s this was only practical with the brush-type DC motor, since such conversion was not well developed in the late 19th century and early 20th century, most early electrified railways used DC and many still do, particularly rapid transit and trams

Current collector
–
Those for overhead wires are roof-mounted devices, those for third rails are mounted on the bogies. Typically, they have one or more spring-loaded arms that permit the working engagement with the rail or overhead wire, the collector arm pushes the contact shoe against the contact wire or rail. As the vehicle moves, the shoe slides along the wire or rail to draw the electricity needed to run the vehicles motor. The current collector arms are electrically conductive but mounted insulated on the vehicles roof, an insulated cable connects the collector with the switch, transformer or motor. The steel rails of the act as the electrical return. Electric vehicles that collect their current from an overhead line system use different forms of one- or two-arm pantograph collectors, the current collection device presses against the underside of the lowest wire of an overhead line system, which is called a contact wire. Most overhead supply systems are either DC or single phase AC, three phase AC systems use a pair of overhead wires, and paired trolley poles. Electric railways with third rails, or fourth rails, in tunnels carry collector shoes projecting laterally, or vertically, the contact shoe may slide on top of the third rail, on the bottom or on the side. The side running contact shoe is used against the bars on rubber-tired metros. A vertical contact shoe is used on power supply systems, stud contact systems. A pair of shoes was used on underground current collection systems. The contact shoe on a contact system is called a ski collector. The ski collector moves vertically to accommodate variations in the height of the studs. Contact shoes may also be used on overhead conductor rails, on bars or on trolley wires. Most railways use three rails, while the London Underground uses four rails

Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

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 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 classed as EMUs. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration, being quieter than DMUs and locomotive-drawn trains, EMUs can operate later at night and more frequently without disturbing residents living near the railway lines. The first EMUs were used on the elevated Liverpool Overhead Railway in 1893, the southern terminal of the railway was underground, giving the LOR the distinction of also being the first to use EMUs underground. Each carriage had a traction motor and was specifically designed and constructed to be light in weight while running on elevated steel sections. The first EMUs were two-carriage trains later graduating to three carriages, with the front and rear carriages powered, Liverpool Museum retains an example of the Liverpool Overhead Railway EMU carriage. An early proponent of EMUs was the American engineer Frank J. Sprague, the cars that form a complete EMU set can usually be separated by function into four types, power car, motor car, driving car, and trailer car. Each car can have more than one function, such as a car or power-driving car. A power car carries the equipment to draw power from the electrified infrastructure, such as pickup shoes for third rail systems and pantographs for overhead systems. Motor cars carry the traction motors to move the train, and are combined with the power car to avoid high-voltage inter-car connections. Driving cars are similar to a cab car, containing a drivers cab for controlling the train, an EMU will usually have two driving cars at its outer ends. Trailer cars are any cars that carry little or no traction or power related equipment, on third rail systems the outer vehicles usually carry the pick up shoes, with the motor vehicles receiving the current via intra-unit connections. Many modern 2-car EMU sets are set up as married pair units, while both units in a married pair are typically driving motors, the ancillary equipment are shared between the two cars in the set. Since neither car can operate without its partner, such sets are permanently coupled, advantages of married pair units include weight and cost savings over single-unit cars while allowing all cars to be powered, unlike a motor-trailer combination. Disadvantages include a loss of flexibility, as trains must be multiples of two cars, and a failure on a single car could force removing both it and its partner from service. The retired New York–Washington Metroliner service, first operated by the Pennsylvania Railroad and later by Amtrak, also featured high-speed electric multiple-unit cars, diesel multiple unit Battery electric multiple unit British electric multiple units Media related to Electric multiple unit at Wikimedia Commons

Listed below are used, all are 10-car formations unless otherwise indicated. Numbers in parentheses are of formations currently in service, in 1964, the plan was changed slightly so that through service would be offered on the Joban Line north of Tokyo, and the number was changed to Line 9. Line 9 was designed to pass through areas in Chiyoda, and also intended to relieve the busy Ginza Line and Hibiya Line. The first stretch was opened on December 20,1969 between Kita-Senju and Ōtemachi, the line was almost completed by October 10,1972 when it reached Yoyogi-Kōen, although the 1 km section to Yoyogi-Uehara was not completed until March 31,1978. The branch line to Kita-Ayase was opened on December 20,1979 and this branch primarily serves as a connection to Ayase Depot, but also serves Kita-Ayase station constructed in the area. A three-car shuttle service operates between Ayase and Kita-Ayase, the Chiyoda Line was one of the lines targeted in the Aum sarin gas attack on 20 March 1995. On May 15,2006, women-only cars were introduced on early-morning trains from Toride on the Joban Line to Yoyogi-Uehara, trains also run from/to Shin-Kiba using tracks connecting to the Yurakucho Line

Friction stir welding
–
Friction stir welding is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. Heat is generated by friction between the tool and the workpiece material, which leads to a softened region near the FSW tool. It is primarily used on wrought or extruded aluminium and particularly for structures which need very high weld strength and it was invented and experimentally proven at The Welding Institute in the UK in December 1991. TWI held patents on the process, the first being the most descriptive, the probe is slightly shorter than the weld depth required, with the tool shoulder riding atop the work surface. After a short time, the tool is moved forward along the joint line at the pre-set welding speed. Frictional heat is generated between the wear-resistant tool and the work pieces and this heat, along with that generated by the mechanical mixing process and the adiabatic heat within the material, cause the stirred materials to soften without melting. As the tool is moved forward, a profile on the probe forces plasticised material from the leading face to the rear. This process of the tool traversing along the line in a plasticised tubular shaft of metal results in severe solid state deformation involving dynamic recrystallization of the base material. The solid-state nature of the FSW process, combined with its unusual shape and asymmetric speed profile. The microstructure can be broken up into the following zones, The stir zone is a region of heavily deformed material that roughly corresponds to the location of the pin during welding. The grains within the zone are roughly equiaxed and often an order of magnitude smaller than the grains in the parent material. A unique feature of the zone is the common occurrence of several concentric rings which has been referred to as an onion-ring structure. The precise origin of these rings has not been established, although variations in particle number density, grain size. The thermo-mechanically affected zone occurs on either side of the stir zone, in this region the strain and temperature are lower and the effect of welding on the microstructure is correspondingly smaller. Unlike the stir zone the microstructure is recognizably that of the parent material, although the term TMAZ technically refers to the entire deformed region it is often used to describe any region not already covered by the terms stir zone and flow arm. The heat-affected zone is common to all welding processes, as indicated by the name, this region is subjected to a thermal cycle but is not deformed during welding. The temperatures are lower than those in the TMAZ but may still have a significant effect if the microstructure is thermally unstable, in fact, in age-hardened aluminium alloys this region commonly exhibits the poorest mechanical properties. The solid-state nature of FSW leads to several advantages over fusion welding methods as problems associated with cooling from the phase are avoided

Pantograph (transport)
–
A pantograph is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead catenary wire. It is a type of current collector. Typically, a wire is used, with the return current running through the track. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting, the pantograph was invented in 1879 by Walter Reichel, chief engineer at Siemens & Halske in Germany. A flat slide-pantograph was invented in 1895 at the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was invented by John Q. Brown of the Key System shops for their commuter trains ran between San Francisco and the East Bay section of the San Francisco Bay Area in California. They appear in photographs of the first day of service,26 October 1903, for many decades thereafter, the same diamond shape was used by electric-rail systems around the world and remains in use by some today. The most common type of today is the so-called half-pantograph. Louis Faiveley invented this type of pantograph in 1955, the half-pantograph can be seen in use on everything from very fast trains to low-speed urban tram systems. The electric transmission system for electric rail systems consists of an upper. The pantograph is spring-loaded and pushes a contact shoe up against the underside of the wire to draw the current needed to run the train. The steel rails of the act as the electrical return. As the train moves, the shoe slides along the wire and can set up standing waves in the wires which break the contact. This means that on some systems adjacent pantographs are not permitted, pantographs are the successor technology to trolley poles, which were widely used on early streetcar systems. However, many of these networks, including Torontos, are undergoing upgrades to accommodate pantograph operation, as a precaution against loss of pressure in the second case, the arm is held in the down position by a catch. For high-voltage systems, the air supply is used to blow out the electric arc when roof-mounted circuit breakers are used. Pantographs may have either a single or a double arm, double-arm pantographs are usually heavier, requiring more power to raise and lower, but may also be more fault-tolerant. On railways of the former USSR, the most widely used pantographs are those with a double arm, some streetcars use double-arm pantographs, among them the Russian KTM-5, KTM-8, LVS-86 and many other Russian-made trams, as well as some Euro-PCC trams in Belgium
