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

Tokyo Metro Namboku Line
–
The Tokyo Metro Namboku Line is a subway line owned and operated by the Tokyo subway operator Tokyo Metro in Tokyo, Japan. Its name literally means South-North Line, the line runs between Meguro in Shinagawa and Akabane-Iwabuchi in Kita. The Namboku Line was referred to as Line 7 during the planning stages, trains run through onto the Tokyu Meguro Line for Hiyoshi and the Saitama Railways Saitama Rapid Railway Line for Urawa-Misono. The portion between Shirokane-Takanawa and Meguro is shared with the Toei Mita Line, the right-of-way and stations between Shirokane-Takanawa and Meguro are shared with the Toei Mita Line - a unique situation on the Tokyo subway where both operators share common infrastructure. On maps, diagrams and signboards, the Namboku Line is shown using the color emerald, all stations are located in Tokyo. Although the line was proposed in 1968, construction did not begin until the 1980s. The first segment from Komagome to Akabane-Iwabuchi opened on November 29,1991, the line initially operated with four-car EMUs. Upon its extension to Yotsuya in March 1996, the formations were extended to six cars, all stations are able to accommodate eight-car trains, but this length is not yet used. Through service with the Saitama Rapid Railway Line commenced when it opened in March 2001 and accommodated traffic to, although the Saitama Line is more or less a northern extension of the Namboku Line, it nevertheless remains a private entity to which the Namboku Line offers through services with

Acceleration
–
Acceleration, in physics, is the rate of change of velocity of an object with respect to time. An objects acceleration is the net result of any and all forces acting on the object, the SI unit for acceleration is metre per second squared. Accelerations are vector quantities and add according to the parallelogram law, as a vector, the calculated net force is equal to the product of the objects mass and its acceleration. For example, when a car starts from a standstill and travels in a line at increasing speeds. If the car turns, there is an acceleration toward the new direction, in this example, we can call the forward acceleration of the car a linear acceleration, which passengers in the car might experience as a force pushing them back into their seats. When changing direction, we call this non-linear acceleration, which passengers might experience as a sideways force. If the speed of the car decreases, this is an acceleration in the direction from the direction of the vehicle. Passengers may experience deceleration as a force lifting them forwards, mathematically, there is no separate formula for deceleration, both are changes in velocity. Each of these accelerations might be felt by passengers until their velocity matches that of the car, an objects average acceleration over a period of time is its change in velocity divided by the duration of the period. Mathematically, a ¯ = Δ v Δ t, instantaneous acceleration, meanwhile, is the limit of the average acceleration over an infinitesimal interval of time. The SI unit of acceleration is the metre per second squared, or metre per second per second, as the velocity in metres per second changes by the acceleration value, every second. An object moving in a circular motion—such as a satellite orbiting the Earth—is accelerating due to the change of direction of motion, in this case it is said to be undergoing centripetal acceleration. Proper acceleration, the acceleration of a relative to a free-fall condition, is measured by an instrument called an accelerometer. As speeds approach the speed of light, relativistic effects become increasingly large and these components are called the tangential acceleration and the normal or radial acceleration. Geometrical analysis of space curves, which explains tangent, normal and binormal, is described by the Frenet–Serret formulas. Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an amount in every equal time period. A frequently cited example of uniform acceleration is that of an object in free fall in a gravitational field. The acceleration of a body in the absence of resistances to motion is dependent only on the gravitational field strength g

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
