M3 (railcar)
The M1 and M3 are two similar series of electric multiple unit rail cars built by the Budd Company for the Long Island Rail Road, the Metro-North Railroad and Metro-North's predecessors, Penn Central and Conrail.Cudahy, p. 264 Originally branded by Budd as Metropolitans, the cars are more popularly known under their model names, M1 (late 1960s/early 1970s cars) and M3 (mid 1980s cars). The Metro North cars were branded under the M1A and M3A series. Overview Even though the LIRR's fleet of some 900 MP54 electric MU cars constructed between 1908 and 1930 had been augmented between 1955-1963 by about 150 newer MP72 and MP75 EMUs, the roster still contained a large number of increasingly elderly prewar cars which the cash strapped LIRR was unable to replace. In 1965 the nearly bankrupt commuter railroad was taken over by the state owned Metropolitan Commuter Transportation Authority, later renamed the Metropolitan Transportation Authority in 1968, which was then able to provide l ...

WABCO N-Type
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

R46 (New York City Subway Car)
The R46 is a New York City Subway car model that was built by the Pullman Company, Pullman Standard Company from 1975 to 1978 for the Independent Subway System, IND/Brooklyn–Manhattan Transit Corporation, BMT B Division (New York City Subway), B Division. They replaced all remaining Arnines, Arnine cars and General Electric-powered R16 (New York City Subway car), R16s, and some R10 (New York City Subway car), R10s. The R46 order initially consisted of 754 single cars, each long, and was the largest single order of passenger cars in United States railroad history at the point of the fleet's completion. The R46 was the second order of 75-foot cars to be ordered for the New York City Subway, after the R44 (New York City Subway car), R44s. The first R46s ran in passenger service on July 14, 1975. The fleet was initially slated to be delivered between 1973 and 1975, but a strike at Pullman's factory delayed final deliveries until 1978. Several hundred cracks were found in the R46 ...

R44 (New York City Subway Car)
The R44 is a New York City Subway car model built by the St. Louis Car Company from 1971 to 1973 for the B Division and the Staten Island Railway (SIR). The cars replaced many R1-R9 series cars, and all remaining 1925 Standard Steel built SIRTOA ME-1 trains, providing Staten Island with a new fleet of railcars. The R44 fleet originally consisted of 352 cars, of which 61 remain in service, all on the Staten Island Railway. The first R44 cars entered service on the subway on April 19, 1972, and on the Staten Island Railway on February 28, 1973. Various modifications were made over the years to the R44 fleet. The R44s set the world speed record for a subway car in 1972, reaching a top speed of . In the early 1990s, the R44 cars were rebuilt by Morrison–Knudsen or the New York City Transit Authority. Though the R160 order replaced all New York City Subway-operated R44s from December 18, 2009 to September 16, 2010 because of structural integrity issues found on them, the State ...

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 ...

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 ...

Metropolitan Transportation Authority
The Metropolitan Transportation Authority (MTA) is a public benefit corporation responsible for public transportation in the New York City metropolitan area of the U.S. state of New York. The MTA is the largest public transit authority in the United States, serving 12 counties in Downstate New York, along with two counties in southwestern Connecticut under contract to the Connecticut Department of Transportation, carrying over 11 million passengers on an average weekday systemwide, and over 850,000 vehicles on its seven toll bridges and two tunnels per weekday. History Founding In February 1965, New York Governor Nelson Rockefeller suggested that the New York State Legislature create an authority to purchase, operate, and modernize the Long Island Rail Road (LIRR). The LIRR, then a subsidiary of the Pennsylvania Railroad (PRR), had been operating under bankruptcy protection since 1949. The proposed authority would also have the power to make contracts or arrangements with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MP75
The ACMUs (short for Air Conditioned Multiple Unit) were a series of electric multiple unit railcars built for the New York Central railroad in three orders between 1950 and 1965. The ACMUs were intended to replace/supplement the original fleet of heavyweight MU cars, some of which dated to the start of electric operations on the New York Central. These were the first New York Central units to offer air conditioning, with sealed windows replacing the drop sash and clerestory types found on earlier cars. The initial set of 100 cars was retired in 1970, upon completion of the M1 railcar delivery, while the second and third orders, totaling 87 cars, remained in service until 2004, when they were replaced by the new M7 fleet. An order of near-identical cars was built for the Long Island Rail Road as the class MP75 in 1963. The LIRR cars were eventually converted to non-powered push-pull coaches before being retired in the late 1990s. History The ACMU fleet was intended to re ...
