New Haven EP-1
The New Haven EP-1 was a class of boxcab electric locomotives built by Baldwin-Westinghouse for the New York, New Haven and Hartford Railroad. The locomotives were part of an electrification project undertaken by the New Haven between Grand Central Terminal in New York City and Stamford, Connecticut. Baldwin-Westinghouse delivered 41 locomotives between 1905–1908, and the New Haven retired the last in 1947. Design The EP-1 had to support two electric systems and three collection methods. The New York Central Railroad's 660 V third rail DC extended from Grand Central to Woodlawn, where New Haven territory began. Westinghouse installed 11 kV overhead line AC from Woodlawn to Stamford. Finally, the New York Central employed overhead lines over railroad switches in place of third rail electrification. To support these myriad methods, Westinghouse installed two sets of pantographs, one for AC and one for DC collection, and a contact shoe for third rail operation. Co ...

Baldwin-Westinghouse Electric Locomotives
Baldwin, the locomotive manufacturer, and Westinghouse, the promoter of AC (alternating current) electrification, joined forces in 1895 to develop AC railway electrification. Soon after the turn of the century, they marketed a single-phase high-voltage system to railroads. From 1904 to 1905 they supplied locomotives carrying a joint builder's plate to a number of American railroads, particularly for the New Haven (the New York, New Haven and Hartford Railroad) line from New York to New Haven, and other New Haven lines. Westinghouse would produce the motors, controls, and other electrical gear, while Baldwin would produce the running gear, frame, body, and (in most cases) perform final assembly. Baldwin-Westinghouse electric locomotives Experimental locomotives In 1895 a box-cab locomotive long with two four-wheel trucks and weighing was built at the East Pittsburgh (Pennsylvania) works of Westinghouse. It was used for more than a decade of AC and DC experimentation. Sol ... [...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 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 Haven EP-2
The New Haven EP-2 was a class of boxcab electric locomotives built by Baldwin-Westinghouse for the New York, New Haven and Hartford Railroad. The locomotives worked passenger trains on the New Haven's electrified division west of New Haven, Connecticut. Baldwin-Westinghouse delivered 27 locomotives between 1919–1927. The locomotives were an enlarged version of the EP-1 and EF-1 designs. They remained in service until the arrival of the dual-mode EMD FL9 locomotives in 1958. Design The New Haven's electrified district extended west from New Haven, Connecticut, to The Bronx, the northernmost borough of New York City. It electrified its lines using 11 kV overhead AC. From Woodlawn to Grand Central Terminal trains ran over the New York Central Railroad's 660 V third rail DC. At Port Morris trains continued over the New York Connecting Railroad to Harold Interlocking in Queens, just short of Pennsylvania Station. This route was jointly electrified by the New Hav ...

New Haven, Connecticut
New Haven is a city in the U.S. state of Connecticut. It is located on New Haven Harbor on the northern shore of Long Island Sound in New Haven County, Connecticut and is part of the New York City metropolitan area. With a population of 134,023 as determined by the 2020 U.S. census, New Haven is the third largest city in Connecticut after Bridgeport and Stamford and the principal municipality of Greater New Haven, which had a total 2020 population of 864,835. New Haven was one of the first planned cities in the U.S. A year after its founding by English Puritans in 1638, eight streets were laid out in a four-by-four grid, creating the "Nine Square Plan". The central common block is the New Haven Green, a square at the center of Downtown New Haven. The Green is now a National Historic Landmark, and the "Nine Square Plan" is recognized by the American Planning Association as a National Planning Landmark. New Haven is the home of Yale University, New Haven's biggest taxpayer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York Tunnel Extension
The New York Tunnel Extension (also New York Improvement and Tunnel Extension) is a combination of railroad tunnels and approaches from New Jersey and Long Island to Pennsylvania Station (New York City), Pennsylvania Station in Midtown Manhattan. It was built by Pennsylvania Railroad (PRR) at the beginning of the 20th century to improve railroad access throughout the greater New York City area, and lead to the line’s then new passenger facility, Pennsylvania Station (1910–1963). Planning The PRR had consolidated its control of railroads in New Jersey with the lease of United New Jersey Railroad and Canal Company in 1871, thereby extending its rail network from Philadelphia northward to Jersey City, New Jersey, Jersey City. Crossing the Hudson River, however, remained a major obstacle. To the east, the Long Island Rail Road (LIRR) ended at the East River. In both situations, passengers had to transfer to ferry, ferries to Manhattan. This put the PRR at a disadvantage relativ ...

Pennsylvania Railroad Class DD1
The Pennsylvania Railroad DD1 was a class of boxcab electric locomotives built by the Pennsylvania Railroad. The locomotives were developed as part of the railroad's New York Tunnel Extension, which built the original Pennsylvania Station in New York City and linked it to New Jersey via the North River Tunnels. The Pennsylvania built a total of 66 locomotives in its Altoona Works; they operated in semi-permanently coupled pairs. Westinghouse supplied the electrical equipment. The first locomotives entered service in 1910, with the opening of Pennsylvania Station. They operated between Manhattan Transfer and Pennsylvania Station, and from there to the coach yards at Sunnyside Yard in Queens, New York. With the arrival of the Class L5 locomotives in 1924, some DD1s moved to the Pennsylvania-owned Long Island Rail Road (LIRR), which had substantial electrified commuter rail operations. The conversion of the New York– Philadelphia main line to alternating current in the 1930s s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Jersey And Seashore Railroad
The West Jersey and Seashore Railroad (WJ&S) was a Pennsylvania Railroad subsidiary in the U.S. state of New Jersey with a connection to Philadelphia. It was formed through the merger of several smaller roads in May 1896. At the end of 1925 it operated of road on of track; that year it reported 166 million ton-miles of revenue freight and 332 million passenger-miles. The railroad became part of Pennsylvania-Reading Seashore Lines in 1933. History On May 4, 1896, the Pennsylvania Railroad (PRR) consolidated all its railroads and several smaller properties in southern New Jersey into the West Jersey and Seashore Railroad (WJ&S). This included the West Jersey Railroad, the Alloway and Quinton Railroad, the Camden and Atlantic Railroad, the Chelsea Branch Railroad, and the Philadelphia, Marlton and Medford Railroad. The consolidation was originally scheduled to occur in March 1896. But at a meeting held on March 21, it was agreed that there was not enough time given for proxy ...

Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, T ...

Multiple Working
On the UK rail network, multiple working is where two or more traction units (locomotives, diesel multiple-units or electric multiple-units) are coupled together in such a way that they are all under the control of one driver (multiple-unit train control). If the front locomotive of a pair in multiple has failed the driver can still control the rear locomotive for as long as air and electricity supplies are available on the failed locomotive. In tandem is when more than one diesel or electric locomotive are hauling a single train and under the control of a driver on each locomotive. Locomotives In the early days of diesel locomotives in the 1960s, locomotives worked within their class (i.e. two locomotives of the same class could work together but not with other classes). Locomotives from different manufacturers had varying methods of controlling engines or braking systems. If a train required more than one locomotive, an additional driver was needed, at extra expense. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogies
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Railroad Switch
A railroad switch (), turnout, or ''set ofpoints () is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off. The most common type of switch consists of a pair of linked tapering rails, known as ''points'' (''switch rails'' or ''point blades''), lying between the diverging outer rails (the ''stock rails''). These points can be moved laterally into one of two positions to direct a train coming from the point blades toward the straight path or the diverging path. A train moving from the narrow end toward the point blades (i.e. it will be directed to one of the two paths, depending on the position of the points) is said to be executing a ''facing-point movement''. For many types of switch, a train coming from either of the converging directions will pass through the switch regardless of the position of the points, as the vehicle's wheels will force the points to move. ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...
