EMD FL9
The EMD FL9 (New Haven Class EDER-5) is a model of electro-diesel locomotive, capable of operating either as a traditional diesel-electric locomotive or as an electric locomotive powered from a third rail ("dual power"). Sixty units were built between October 1956 and November 1960 by General Motors Electro-Motive Division for the New York, New Haven and Hartford Railroad (the "New Haven"). The locomotives were designed to allow diesel powered trains to enter Grand Central Terminal, where non-electric locomotives are forbidden. The FL9s continued in passenger service under the New Haven's successors, with the final units in revenue service retired by Metro-North Railroad in 2009. A number of FL9s have been preserved at museums or with private owners. Design Due to concerns about diesel emissions in the East River Tunnels and the underground tracks of Grand Central Terminal and Penn Station, passenger trains entering New York City have long been required to use electrical powe ...

Enfield Station (Connecticut)
Enfield station is a planned CT''rail'' Hartford Line station in Enfield, Connecticut. , construction is expected to begin in 2025. A previous station at the site was open from 1844 to 1986. History Amtrak The Hartford and New Haven Railroad (H&NH) opened from Hartford Union Station, Hartford to Springfield Union Station (Massachusetts), Springfield in December 1844. Thompsonville station, located on the east side of the tracks just north of Main Street, opened with the line. It was replaced by a two-story brick station around 1870, with a wooden addition for the Railway Express Agency built later on the north end of the structure. In 1946, the second story - then rented out as apartments - and the wooden addition were removed. The modified station building was used until 1971, when Penn Central closed it shortly before Amtrak took over passenger service. Thompsonville remained a stop - daily ridership exceeded 40 on the ''Connecticut Yankee'' in 1974 - but passengers waited on ...

Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the Rail profile, rails. Other types of current collectors include the bow collector and the trolley pole. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "current collector, shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad. The familiar diamond-shaped roller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexicoil
Flexicoil suspension is a type of secondary suspension for railway vehicles, typically having steel coil springs between the bogies and chassis of a passenger coach, freight car, or locomotive. Suspension systems using steel springs are more common than those with air springs, as steel springs are less costly to make, relatively wear resistant, and require less maintenance. History Flexicoil (though not known by this term) suspensions were fitted to locomotives in Spain, the Soviet Union and Africa as early as the 1930s. In Germany, Flexicoil suspensions were first used in the 1950s under high-speed electric locomotives, notably the DB Class 103. British Rail Between 1969 and 1971, British Rail conducted tests of modified Flexicoil bogies under a modified Class 86, to prevent further track damage caused by the original Class 86 bogies; tests were successful and all Class 86 locomotives were refitted with the modifications in stages through the 1970s and 1980s. ...

Wheel Arrangement
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. Major notation schemes The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classifi ...

Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for ... (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead (except geared steam locomotives, which are instead classified by their model and their number of trucks). The AAR system (like UIC) counts axles, unlike Whyte, which counts wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to t ...

EMD FP9
The EMD FP9 is an American , B-B dual-service passenger and freight-hauling diesel locomotive that was produced between February 1954 and December 1959 by General Motors Electro-Motive Division, and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, except for Canadian orders, which were assembled by Canadian subsidiary GMD at London, Ontario. The FP9 was essentially EMD's F9 locomotive extended by to give greater steam generator and water capacity for hauling passenger trains. A total of 86 cab-equipped lead A units were built; unlike the freight series, no cabless booster B units were sold. Regular F9B units were sometimes used with FP9 A units, since they, lacking cabs, had more room for water and steam generators. The FP9 and its predecessor, the FP7, were offshoots of GM-EMD's highly successful F-unit series of cab unit diesel locomotives. Original owners EMD built 86 FP9 locomotives. The two largest buyers were the Canadian National Ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

East River Tunnels
The East River Tunnels are four single-track railroad passenger service tunnels that extend from the eastern end of Pennsylvania Station under 32nd and 33rd Streets in Manhattan and cross the East River to Long Island City in Queens. The tracks carry Long Island Rail Road (LIRR) and Amtrak trains travelling to and from Penn Station and points to the north and east. The tracks also carry New Jersey Transit trains deadheading to Sunnyside Yard. They are part of Amtrak's Northeast Corridor, used by trains traveling between New York City and New England via the Hell Gate Bridge. History Construction The tunnels were built in the first decade of the 20th century as part of the New York Tunnel Extension. The original plan for the extension which was published in June 1901, called for the construction of a bridge across the Hudson River between 45th and 50th Streets in Manhattan, as well as two closely spaced terminals for the LIRR and Pennsylvania Railroad (PRR). This would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a Battery (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
