H Series (Toronto Subway)
The H series is 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 H-1 to H-6, from 1965 to 1990 in Thunder Bay, Ontario, for the Toronto Transit Commission (TTC). The entire rolling stock was retired in 2014, though thirteen remaining cars still exist as work cars, including three H-1 cars. 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 H-6 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 con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankara Metro
The Ankara Metro () is the rapid transit system serving Ankara, the capital of Turkey. At present, Ankara's rapid transit system consists of three metro lines – the ''Ankaray (A1)'', the ''M1 - M2 - M3'' and the ''M4''. The Ankaray, M1, M2, M3 and M4 lines transported 172.1 million passengers in 2024. That corresponds to a ridership of approximately 470,185 per day. In July 2018, the lines M1 and M3 were merged into a single line. Subsequently, in February 2019, the line M2 was also integrated into that service. This merger provides uninterrupted service between Koru and OSB-Törekent. History Ankaray The ''Ankaray'' (from , meaning ''Ankara rail''), a light rail transit system (, though the line does operate as more of a "medium-capacity rail transport system, light metro" line) was the first phase of the modern rapid transit network of the city. The ''Ankaray'' was constructed by a consortium headed by Siemens over a period of four years (1992–96). It opened on 30 Aug ...

Rolling Stock
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, Railroad car#Freight cars, freight and Passenger railroad car, passenger cars (or coaches), and Railroad car#Non-revenue cars, non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, Railcar, single or Multiple unit, multiple units. In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock comprising a train, a list containing specific information for each car of a train, or a group of locomotives. 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 ship ...

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 (amusement park), La Ronde in Montreal, Montreal, Quebec, Canada. Built for the 1967 World's Fair (Expo 67) at a cost of around Canadian dollar, CAD$18 million, the trains carried 1,000 passengers each and ran approximately every five minutes. In 1968, the cars were sold to the Montreal#Government, City of Montreal for $1.8 million and operated by the Montreal Transit Commission (now the Société de transport de Montréal, STM). The train remained in limited service for Expo 67#Man and His World (1968–1984), Man and His World for six additional years, however, on a shortened route from 1969-onwards when tracks were cut back to Saint Helen's Island. Service ended in 1973. 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 an ...

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 ...

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 it 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 in 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, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T-series (Toronto Subway)
The T series, also known as the T-1, is the fourth series of rapid transit rolling stock used in the Toronto subway, 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 T-1s 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 T-1 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 (Toronto subway), 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 eleven tram, streetcar routes in Toronto, Ontario, Canada, operated by the Toronto Transit Commission (TTC). It is the List of North American light rail systems by ridership, third busiest light-rail system in North America. The network is concentrated primarily in Downtown Toronto and in proximity to the city's Toronto waterfront, waterfront. Much of the streetcar route network dates from the second half of the 19th century. Three streetcar routes operate in their own right-of-way, one in a partial right-of-way, and six operate on street trackage shared with vehicular traffic with streetcars stopping on demand at frequent stops like buses. Since 2019, the network has used Low-floor tram, low-floor streetcars, making it fully accessible. 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 ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presidents' Conference Committee (Toronto Streetcar)
The Presidents' Conference Committee (PCC) is a streetcar (tram) design that was first built in the United States in the 1930s. The design proved successful domestically, and after World War II it was licensed for use elsewhere in the world where PCC based cars were made. The PCC car has proved to be a long-lasting icon of streetcar design. Approximately 5,000 PCC streetcars were built in the United States, with production continuing until 1952. In North America, some PCC streetcars are still in regular service, with most operating on Heritage streetcar, heritage streetcar lines. , the San Francisco Municipal Railway is the largest North American operator of PCC cars, using a fleet of 27 on two heritage lines. After World War II, the PCC design was licensed to multiple European companies. Over 15,000 PCC-derived streetcars were built in Europe, including the popular Tatra T3.
