Deck Roof (New York City Subway Car)
The Deck Roof Hi-V was a New York City Subway car class built from 1907 to 1908 by the American Car and Foundry for the IRT and its successors, the New York City Board of Transportation and the New York City Transit Authority. Description A total of 50 Deck Roofs were built, numbered 3650–3699. These cars were in service from 1907 to 1958. These cars were nicknamed the Battleships because of their paint scheme where the siding was painted Battleship Grey. When these cars were delivered, they had two doors on each side until the early 1910s, when they received another door in the middle on each side. The facing cross seats in the center, typical of el cars, were removed to accommodate the added center doors. At the same time, as with the Gibbs cars, these Deck Roof cars were retrofitted with the more advanced type couplers and AMRE triple valve braking system introduced in the later Hedley High-V motors. As with the Gibbs cars, many of these Deck Roof cars received motors ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Car And Foundry
ACF Industries, originally the American Car and Foundry Company (abbreviated as ACF), is an American manufacturer of railroad rolling stock. One of its subsidiaries was once (1925–54) a manufacturer of motor coaches and trolley coaches under the brand names of (first) ACF and (later) ACF-Brill. Today, the company is known as ACF Industries LLC and is based in St. Charles, Missouri. It is owned by investor Carl Icahn. History The American Car and Foundry Company was originally formed and incorporated in New Jersey in 1899 as a result of the merger of thirteen smaller railroad car manufacturers: Later in 1899, ACF acquired the Bloomsburg Car Manufacturing Company of Bloomsburg, Pennsylvania. Orders for new freight cars were made very quickly, with several hundred cars ordered in the first year alone. Two years later, ACF acquired the Jackson and Sharp Company (founded 1863 in Wilmington, Delaware) and the Common Sense Bolster Company (of Chicago, Illinois). The unified c ...

Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a track (rail transport), railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third-rail systems are usually supplied with direct current. Modern tram systems with street running avoid the electrical injury risk of the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge, dual-gauge railways. The system is generally associated with a low voltage (rarely above 750 V) and is far less used for main lines than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York City Subway Rolling Stock
The New York City Subway is a large rapid transit system and has a large fleet of electric multiple unit rolling stock. , the New York City Subway has cars on the roster. The system maintains two separate fleets of passenger cars: one for the A Division (numbered) routes, the other for the B Division (lettered) routes. All A Division equipment is approximately wide and long. B Division cars, on the other hand, are about wide and either or long. The A Division and B Division trains operate only in their own division; operating in the other division is not allowed. All rolling stock, in both the A and B Divisions, run on the same standard gauge and use the same third-rail geometry and voltage. A typical revenue train consists of 8 to 10 cars, although in practice they can range between 2 and 11 cars. The subway's rolling stock have operated under various companies: the Interborough Rapid Transit (IRT), Brooklyn–Manhattan Transit (BMT), and Independent Subway S ...

Shore Line Trolley Museum
The Shore Line Trolley Museum is a trolley museum located in East Haven, Connecticut. Incorporated in 1945, it is the oldest continuously operating trolley museum in the United States. The museum includes exhibits on trolley history in the visitors' center and offers rides on restored trolleys along its track as the Branford Electric Railway. In addition to trolleys, the museum also operates restored subway cars, a small number of both trolleybuses and conventional buses. The museum encompasses the Branford Electric Railway Historic District, which was added to the U.S. National Register of Historic Places in 1983. History The museum was incorporated in August 1945 as the Branford Electric Railway Association (BERA), a non-profit historical and educational institution. The Connecticut Company (or ConnCo), which operated most of the streetcar lines in the state of Connecticut, had been making plans since the early 1930s to abandon its "F" route, cutting it back in stages fro ...

New York City Subway
The New York City Subway is a rapid transit system in New York City serving the New York City boroughs, boroughs of Manhattan, Brooklyn, Queens, and the Bronx. It is owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the Government of New York (state), state-run Metropolitan Transportation Authority (MTA). Opened on October 27, 1904, the New York City Subway is one of the world's oldest public transit systems, one of the most-used, and the one with the second-most stations after the Beijing Subway, with New York City Subway stations, 472 stations in operation (423, if stations connected by transfers are counted as single stations). The system has operated 24/7 service every day of the year throughout most of its history, barring emergencies and disasters. By annual ridership, the New York City Subway is the busiest rapid transit system in both the Western Hemisphere and the Western world, as well as the List of m ...

Westinghouse Air Brake Company
The Westinghouse Air Brake Technologies Corporation (WABCO) was an American company founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania. Earlier in the year he had invented the railway air brake in New York state. After having manufactured equipment in Pittsburgh for a number of years, he began to construct facilities and plants east of the city where homes for his employees were built. In 1889, the air brake manufacturing facility was moved to Wilmerding, Pennsylvania, and the company's general office building was built there in 1890. In 1921 the company began manufacturing a modified air brake system for installation in trucks and heavy vehicles. In 1953 WABCO entered the heavy equipment marketplace, buying the assets of leading equipment designer R.G LeTourneau. An entity known as "LeTourneau-Westinghouse" sold a range of innovative products, including scrapers, cranes and bulldozers until 1967, when it shortened its name to "Wabco". In 196 ...

Contact Shoe
A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and Electric multiple unit, EMUs to carry electric power (Electric current, current) from overhead lines, electric third rails, or ground-level power supply, ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrical conductivity, electrically conductive but mounted Electrical insulation, insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or Electric motor, motor. The Rail profile, stee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
