Hi-V (New York City Subway Car)
The Hedley Hi-V was a New York City Subway car class built from 1910 to 1911, which were motor cars, and then in 1915 an order for trailers that were numbered 4223–4514. All were built by the American Car and Foundry, Standard Steel Car Company, Pressed Steel Car Company, and Pullman Company. These were the first cars built with center doors. They were also the last high voltage cars built for the system because high voltage cars were a hazard to both the train operators and track crews. Thus, all subway cars delivered afterward were low voltage cars. __TOC__ Service history The order for Hedley High-V motors consisted of 325 cars, with 110 built by American Car and Foundry, 40 by Standard Steel and 175 by Pressed Steel. As delivered, the Hedley High-V motors were the first cars to be delivered with center doors on the sides, with all side seats to provide for them; the facing cross seats of previous cars being eliminated. They were also the first with the advanced couplers ... [...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. The company was made up of: 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 Chic ...

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 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 from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by 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 railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

New York City Subway Rolling Stock
The New York City Subway is a large rapid transit system and has a large fleet of 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 System (IND), all of which hav ...

Standard Lo-V (New York City Subway Car)
The Standard Lo-V (an abbreviation for “Low-Voltage car”) was a New York City Subway car type built from 1916 to 1925 by the Pressed Steel Car Company, American Car and Foundry, and Pullman Company for the IRT. A total of 1,020 cars were built, which consisted of 725 motors and 295 trailers. It was the third and most common "Lo-V" type car ordered for the IRT (after the Flivver Lo-Vs and the first Steinway Lo-Vs). Description The Pullman Co. built the first orders of these cars in 1916 consisting of 123 plus 40 motors and 62 plus 15 trailers; in 1917, consisting of 337 motors and 140 trailers; in 1922, consisting of 100 trailers, and finally by American Car and Foundry in 1924 with 100 motors and 1925 with 125 motors. Car 5302, as part of the 1917 order, was a pay car from the very beginning and was never in passenger service. Low-Vs were arranged in mixed trains consisting of trailer cars and motor cars. While trailer cars were equipped with brakes, but no air compres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck Roof Hi-V (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 remained in service from 1907 to 1957. 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 motor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibbs Hi-V (New York City Subway Car)
The Gibbs Hi-V was a New York City Subway car class built from 1904 to 1905 by American Car and Foundry for the IRT and its successors, the New York City Board of Transportation and the New York City Transit Authority. It was the first all-steel subway car ordered for New York City. Because of the sliding doors which enclosed the motorman's vestibules from the rest of the car compartment, the cars were nicknamed Merry Widows. Early on, they were also known as Battleships, a reference to their second paint scheme where the siding was painted Battleship Grey. However, the nickname did not stick and was later given to the Deck Roof Hi-V cars, which were painted the same color. Today, references to the "Battleships" are generally assumed to be in reference to the Deck Roof cars, as opposed to the Gibbs cars. Background information As the Interborough Rapid Transit Company's subway line was the first attempt at an underground rapid transit, the IRT and chief engineer George Gibbs ...

New York City Subway
The New York City Subway is a rapid transit system owned by the government of New York City and leased to the New York City Transit Authority, an affiliate agency of the 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 most stations, with New York City Subway stations, 472 stations in operation (424 if stations connected by transfers are counted as single stations). Stations are located throughout the boroughs of Manhattan, Brooklyn, Queens, and the Bronx. 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 metro systems, seventh-busiest rapid transit rail system in the world. In , the subway deliv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westinghouse Air Brake Company
The Westinghouse Air Brake Company (sometimes nicknamed or abbreviated WABCO although this was also confusingly used for spinoffs) was 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 196 ...

Contact Shoe
Electric current collectors are used by trolleybuses, trams, electric locomotives or EMUs to carry electrical power from overhead lines, electrical third rails, or 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 electrically conductive but mounted insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or motor. The steel rails of the tracks 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 ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A 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 ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...
