Electronically Controlled Pneumatic Brakes
Electronically controlled pneumatic brakes are a type of railway braking systems. Overview Traditional train braking systems use pneumatic valves to control and generate brake applications on the cars along the length of the train. In general, this conventional system consists of a brake pipe that runs the length of the train which supplies air to reservoirs mounted on each of the cars. When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders. To release the brakes, the engineer charges the brake pipe. This method of controlling the brakes on freight and passenger cars has remained virtually unchanged since its invention by George Westinghouse in 1868. The conventional braking system suffers from many weakness ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Brake
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains. Early developments In the earliest days of railways, braking technology was primitive. The first trains had brakes operative on the locomotive tender and on vehicles in the train, where "porters" or, in the United States brakemen, travelling for the purpose on those vehicles operated the brakes. Some railways fitted a special deep-noted brake whistle to locomotives to indicate to the porters the necessity to apply the brakes. All the brakes at this stage of development were applied by operation of a screw and linkage to brake bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osaka Metro
The is a major rapid transit system in the Osaka metropolitan area of Japan, operated by the Osaka Metro Company, Ltd. It serves the city of Osaka and the adjacent municipalities of Higashiosaka, Kadoma, Moriguchi, Sakai, Suita, and Yao. Osaka Metro forms an integral part of the extensive mass transit system of Greater Osaka (part of the Kansai region), having 123 out of the 1,108 rail stations (2007) in the Osaka-Kobe-Kyoto region. In 2010, the greater Osaka region had 13 million rail passengers daily (see Transport in Keihanshin) of which the Osaka Municipal Subway (as it was then known) accounted for 2.29 million. Osaka Metro is the only subway system in Japan to be partially legally classified as a tram system, whereas all other subway systems in Japan are legally classified as railways. Despite this, it has all the characteristics typical of a full-fledged metro system. Overview The network's first service, the Midōsuji Line from to , opened in 1933. As a nort ...

Transnet Freight Rail
Transnet Freight Rail is a South African rail transport company, formerly known as Spoornet. It was part of the South African Railways and Harbours Administration, a state-controlled organisation that employed hundreds of thousands of people for decades from the first half of the 20th century and was widely referred to by the initials SAR&H (SAS&H in Afrikaans). Customer complaints about serious problems with Transnet Freight Rail's service were reported in 2010. Its head office is in Inyanda House in Parktown, Johannesburg. History Railways were first developed in the area surrounding Cape Town and later in Durban around the 1840s. The first line opened in Durban on 27 June 1850. The initial network was created to serve the agricultural production area between Cape Town and Wellington. The news that there were gold deposits in the Transvaal Republic moved the Cape Colony Government (supported by British Government) to link Kimberley as soon as possible by rail to Cape Town ...

Trains (magazine)
''Trains'' is a monthly magazine about trains and railroads aimed at railroad enthusiasts and railroad industry employees. The magazine primarily covers railroad happenings in the United States and Canada, but has some articles on railroading elsewhere. It was founded as ''Trains'' in 1940 by publisher Al C. Kalmbach and editorial director Linn Westcott. From October 1951 to March 1954, the magazine was named ''Trains and Travel''. Jim Wrinn, a former reporter and editor at the '' Charlotte Observer'', served as editor from 2004 until his death in 2022. Carl A. Swanson succeeded him.

High-speed Rail
High-speed rail (HSR) is a type of rail transport network utilising trains that run significantly faster than those of traditional rail, using an integrated system of specialised rolling stock and dedicated railway track, tracks. While there is no single definition or standard that applies worldwide, lines built to handle speeds of at least or upgraded lines of at least are generally considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Honshu, Japan, in 1964. Due to the streamlined spitzer (bullet), spitzer-shaped nose cone of the 0 Series Shinkansen, trains, the system also became known by its English nickname bullet train. Japan's example was followed by several European countries, initially in High-speed rail in Italy, Italy with the Florence–Rome high-speed railway, Direttissima line, followed shortly thereafter by High-speed rail in France, France, High-speed rail in Germany, Germany, and High-speed rail in Spain, ...

200 Series Shinkansen
The was a Shinkansen high-speed train type introduced by Japanese National Railways (JNR) for the Tohoku Shinkansen and Joetsu Shinkansen high-speed rail lines in Japan, and operated by East Japan Railway Company (JR East) until 2013. They actually predated the 100 Series Shinkansen, 100 series trains, having been built between 1980 and 1986. It was one of the two recipients of the 23rd Laurel Prize presented by the Japan Railfan Club, the first Shinkansen type to receive that award. The last remaining sets were retired from regular service in March 2013, and were completely withdrawn from service in April 2013. Design The 200 Series Shinkansen trains resembled the earlier 0 Series Shinkansen, 0 series trains in styling (some later units had the pointed 'shark nose' of the 100 series), but were lighter and more powerful, since these two lines are mountain routes and have steeper gradients. These lines are also prone to snowfall and the trains had small snowplows fitted, as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regenerative Brake
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effectively turning the traction motor into a generator. Feeding power backwards through the system like this allows the energy harvested from deceleration to resupply an energy storage solution such as a battery or a capacitor. Once stored, this power can then be later used to aid forward propulsion. Because of the electrified vehicle architecture required for such a braking system, automotive regenerative brakes are most commonly found on hybrid and electric vehicles. This method contrasts with conventional braking systems, where excess kinetic energy is converted to unwanted and wasted heat due to friction ...
