H Series (Toronto Subway)
The H series was the third series of rapid transit rolling stock used in the subway system of Toronto, Ontario, Canada. They were built in six production sets, named H1 to H6, from 1965 to 1990 in Thunder Bay, Ontario, for the Toronto Transit Commission (TTC). The first five sets were manufactured by Hawker Siddeley Canada until 1979, when the company was purchased by the Urban Transportation Development Corporation (UTDC), which then took over production. They operated alongside their predecessor models, the M series, while the H6 trains replaced the last remaining G-series trains in 1990. All H-series cars were manufactured in a facility Hawker Siddeley inherited from Canadian Car & Foundry, which had earlier produced PCC streetcars for the TTC's streetcar network. The facility was taken over by Bombardier Transportation in 1991, which has continued to produce all subsequent rolling stock for the subway. They include the successor of the H series, the T series, introduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankara Metro
The Ankara Metro ( tr, Ankara Metrosu) is the rapid transit system serving Ankara, the capital of Turkey. At present, Ankara's rapid transit system consists of two metro lines – the ''Batıkent Metrosu (M1)''and the new ''Keçiören Metrosu (M4)'' line opened in 2017, along with the light rail ''Ankaray'' line. The Ankaray, the M1 and M4 lines, together transported 104.1 million passengers in 2014. That corresponds to a ridership of approximately 289,155 per day. In February 2019 all the lines that used to run M1, M2 and M3 were merged to create one line, M1. The '' Kızılay to Atatürk Cultural Center'' link of M4 is not yet opened and remains under construction. Also, an additional line (approx. 25 km long) between Kuyubaşı and Esenboğa International Airport is in the planning stages and would make up the next phase of expansion of the metro. History Ankaray The ''Ankaray'' (from tr, Ankara ray, meaning ''Ankara rail''), a light rail system ( tr, Hafif Ray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling Stock
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, freight and passenger cars (or coaches), and non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, single or multiple units. A connected series of railway vehicles is a train (this term applied to a locomotive is a common misnomer). In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock in a train. In the United States, the term ''rolling stock'' has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways. The word ''stock'' in the term is used in a sense of inventory. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then shipped to the buyer without much cost or delay. The term contrasts with fixed stock (infrastru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montreal
Montreal ( ; officially Montréal, ) is the List of the largest municipalities in Canada by population, second-most populous city in Canada and List of towns in Quebec, most populous city in the Provinces and territories of Canada, Canadian province of Quebec. Founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built. The city is centred on the Island of Montreal, which obtained its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is east of the national capital Ottawa, and southwest of the provincial capital, Quebec City. As of 2021, the city had a population of 1,762,949, and a Census Metropolitan Area#Census metropolitan areas, metropolitan population of 4,291,732, making it the List of the largest municipalities in Canada by population, second-largest city, and List of cen ...

Expo Express
The Expo Express was a rapid transit system consisting of five stations and a route, running from Cité du Havre to La Ronde in Montreal, Quebec, Canada. Built for the 1967 World's Fair (Expo 67) at a cost of around CAD$18 million, the trains carried 1,000 passengers each and ran approximately every five minutes. In 1968 the cars were sold to the City of Montreal for $1.8 million and operated by the Montreal Transit Commission (now the STM). The train remained in limited service for Man and His World for five additional years, however, on a shortened route from 1969-onwards when tracks were cut back to Saint Helen's Island. Service was withdrawn in 1972. Vehicles Not to be confused with the Minirail monorail which ran within the perimeters of the Expo Site, the Expo Express used standard railway technology, with two running rails and a third electrified rail identical to those of the Toronto subway. In fact, the trains used were a modified version of the Hawker Siddeley ... [...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 into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...

Chopper (electronics)
In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another. In power electronics applications, since the switching element is either fully on or fully off, its losses are low and the circuit can provide high efficiency. However, the current supplied to the load is discontinuous and may require smoothing or a high switching frequency to avoid undesirable effects. In signal processing circuits, use of a chopper stabilizes a system against drift of electronic components; the original signal can be recovered after amplification or other processing by a synchronous demodulator that essentially un-does the "chopping" process.

Railway Age
''Railway Age'' is an American trade magazine for the rail transport industry. It was founded in 1856 in Chicago (the United States' major railroad hub) and is published monthly by Simmons-Boardman Publishing Corporation. History The magazine's original title was the ''Western Railroad Gazette,'' and was renamed the ''Railroad Gazette'' in 1870. In June 1908, after purchasing its chief rival, ''The Railway Age'' (founded in 1876 in Chicago), it changed its title to ''Railroad Age Gazette'', then in January 1910, to ''Railway Age Gazette''. In 1918 it shortened its name to the current title. ''Railway Review'' (originally the ''Chicago Railway Review'') was merged into ''Railway Age'' in 1927. Publications that have been merged into ''Railway Age'' include ''American Railroad Journal'', founded 1832, renamed ''The Railroad and Engineering Journal'' in 1887 by its then new owner/editor, Matthias N. Forney. It became ''American Engineer & Railroad Journal'' in 1883, then ''Railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T-series (Toronto Subway)
The T series, also known as the T1, is the fourth series of rapid transit rolling stock used in the subway system of Toronto, Ontario, Canada. They were ordered by the Toronto Transit Commission (TTC) in 1992 and built in one production set between 1995 and 2001 by Bombardier Transportation in Thunder Bay, Ontario, Canada. Currently based entirely out of Greenwood Subway Yard, the T1s are the older of the two currently active series of rolling stock on the heavy-rail lines in the Toronto subway network. Following the introduction of the newer Toronto Rocket train sets, all T1 trains now operate exclusively in six-car configurations on Line 2 Bloor–Danforth. They previously operated on Line 1 Yonge–University and in a four-car configuration on Line 4 Sheppard until the retirement of the last remaining H-series trains in 2014 and until the implementation of one-person train operation on the latter in 2016.

Toronto Streetcar System
The Toronto streetcar system is a network of nine streetcar routes in Toronto, Ontario, Canada, operated by the Toronto Transit Commission (TTC). It is the busiest light-rail system in North America. The network is concentrated primarily in Downtown Toronto and in proximity to the city's waterfront. Much of the streetcar route network dates from the 19th century. Most of Toronto's streetcar routes operate on street trackage shared with vehicular traffic, and streetcars stop on demand at frequent stops like buses. Toronto's streetcars provide most of the downtown core's surface transit service. Four of the TTC's five most heavily used surface routes are streetcar routes. In , the system had a ridership of , or about per weekday as of . History Pre-TTC history (1861–1921) The main predecessors of the TTC were: * Toronto Street Railway (1861–1891) * Toronto Railway Company (1891–1921) * Toronto Civic Railways (1911–1921) In 1861, the City of Toronto issued a thir ...

Presidents' Conference Committee (Toronto Streetcar)
The Presidents' Conference Committee Car was a streetcar used by the Toronto Transportation Commission and the Toronto Transit Commission. The PCC streetcar was designed by the Presidents' Conference Committee, a group of transit operators in the United States and Canada. The TTC purchased 745 PCC streetcars in all, making it the largest PCC fleet in North America. Of that, 317 were air-electric (with air-compressor) and 428 all-electric (no air-compressor); 540 ordered new and 205 used (from several U.S. operators abandoning streetcar service). 175 PCCs had couplers for multiple-unit operation, and the TTC used them to assemble 2-car PCC trains. The TTC had only a maximum of 744 PCCs in service because car 4063 was scrapped after it derailed and crashed into Lansdowne Carhouse wall on 20 January 1947. Today, only two PCCs remain in Toronto, bearing the original 1951 fleet numbers of 4500 and 4549, for charters and special events. Most of the PCCs were scrapped, with some becomin ...
