R8A (New York City Subway Car)
The R8A was a class of New York City Subway revenue cars built in 1939 by the St. Louis Car Company, and used to gather and transport tokens from stations along the IND division. 66 and 67 were the only two cars built; in their final years, they were renumbered twice, first as 20176 and 20177, and again as 30176 and 30177. Being blind motors, the cars were usually towed around by a set of out of service R1-9 cars. 66 was last operated in 1970, after which it was removed from service, and sent to Jamaica Yard The New York City Transit Authority operates a total of 24 rail yards for the New York City Subway system, and one for the Staten Island Railway. There are 10 active A Division yards and 11 active B Division yards, two of which are shared betwee ... Training Services, to be used as a shed. It was removed some time before 1990 and scrapped.

Independent Subway System
The Independent Subway System (IND or ISS), formerly known as the Independent City-Owned Subway System (ICOSS) or the Independent City-Owned Rapid Transit Railroad (ICORTR), was a rapid transit rail system in New York City that is now part of the New York City Subway. It was first constructed as the Eighth Avenue Line in Manhattan in 1932. One of three rail networks that became part of the modern New York City subway, the IND was intended to be fully owned and operated by the municipal government, in contrast to the privately operated or jointly funded Interborough Rapid Transit Company (IRT) and Brooklyn–Manhattan Transit Corporation (BMT) companies. It was merged with these two networks in 1940. The original IND service lines are the modern subway's A, B, C, D, E, F, and G services. In addition, the BMT's M, N, Q and R now run partly on IND trackage. The Rockaway Park Shuttle supplements the A service. For operational purposes, the IND and BMT lines and service ...

New York City Board Of Transportation
The New York City Board of Transportation or the Board of Transportation of the City of New York (NYCBOT or BOT) was a city transit commission and operator in New York City, consisting of three members appointed by the mayor. It was created in 1924 to control city-owned and operated public transportation service within the New York City Transit System. The agency oversaw the construction and operation of the municipal Independent Subway System (IND), which was constructed shortly after the Board was chartered. The BOT later presided over the major transfers of public transit from private control to municipal control that took place in the 1940s, including the unification of the New York City Subway in 1940. In 1953, the Board was dissolved and replaced by the state-operated New York City Transit Authority, now part of the Metropolitan Transportation Authority (MTA).

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] |
Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

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 ...

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 ...

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 ...

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 ...

Air Brake (rail)
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. The ...

Money Train
A money train is one or more railcars used to collect cash fare revenue from stations on a subway system and return it to a central location for processing. This train was typically used to carry money bags guarded by transit police to deter robberies. On the New York City Subway, a “money train” was first mentioned in 1905, a year after the system opened. Their trains were converted from subway cars that have been removed from passenger service. This has since been discontinued, with the last service running in January 2006. Two of the cars are preserved by the New York Transit Museum in Brooklyn. The use of a train was necessary because of difficulties in getting to and from stations using over-street transport, and because, since the subway reaches every station, the rail system itself can be used to collect money from ticket machines. The 1995 American crime thriller film ''Money Train'' depicts a robbery of such a train. Singapore's Mass Rapid Transit system intro ...

B Unit
B, or b, is the second letter of the Latin-script alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is '' bee'' (pronounced ), plural ''bees''. It represents the voiced bilabial stop in many languages, including English. In some other languages, it is used to represent other bilabial consonants. History Old English was originally written in runes, whose equivalent letter was beorc , meaning "birch". Beorc dates to at least the 2nd-century Elder Futhark, which is now thought to have derived from the Old Italic alphabets' either directly or via Latin . The uncial and half-uncial introduced by the Gregorian and Irish missions gradually developed into the Insular scripts' . These Old English Latin alphabets supplanted the earlier runes, whose use was fully banned under King Canute in the early 11th century. The Norman Conquest popularised the Carolingian half-uncial forms which lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arnines
The Arnines (R1-9s) were the 1,703 similar New York City Subway cars built between 1930 and 1940 for the Independent Subway System. All were built by the American Car and Foundry Company, the Pressed Steel Car Company, and Pullman Standard. The name comes from the literal spelling out of the final contract under which these 1,703 cars were ordered – contract "R9". The complete listing of contract numbers for cars referred to as “Arnines” include: R1, R4, R6, R7/A, and R9. Also in the Arnine family was the R8A, which was a revenue collection car, or Money train. The Arnines entered service between 1931 and 1940 and remained in service until they were replaced between 1968 and 1977 with R40, R42, R44, and R46 cars. The last of the cars in this broad grouping were removed from passenger service in 1977. Many pieces of memorabilia, including rollsigns and car number plates, exist today in museums and private collections. Preservation Today, twenty of these cars rema ...
