GG1
The Pennsylvania Railroad GG1 is a class of streamlined electric locomotives built for the Pennsylvania Railroad (PRR), in the northeastern United States. The class was known for its striking art deco shell, its ability to pull trains at up to 100 mph, and its long operating career of almost 50 years. Between 1934 and 1943, General Electric and the PRR's Altoona Works built 139 GG1s. The GG1 entered service with the PRR in 1935 and later ran on successor railroads Penn Central, Conrail, and Amtrak. The last GG1 was retired by New Jersey Transit in 1983. Most have been scrapped, but 16 are in museums. Technical information Body and mechanical The GG1 was long and weighed . The frame of the locomotive was in two halves joined with a ball joint, allowing the locomotive to negotiate sharper curves. The body rested on the frame and was clad in welded steel plates. The control cabs were near the center of the locomotive on each side of the main oil-cooled transformer and oil-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

PRR P5
The Pennsylvania Railroad's class P5 comprised 92 mixed-traffic electric locomotives constructed 1931–1935 by the PRR, Westinghouse and General Electric. Although the original intention was that they work many passenger trains, the success of the GG1 locomotives meant that the P5 class were mostly used on freight. A single survivor, prototype #4700, is at the National Museum of Transportation in St Louis, Missouri. They had an AAR wheel arrangement of 2-C-2, or 2′ in the UIC classification system — three pairs of driven wheels rigidly mounted to the locomotive, with a two-axle unpowered truck at each end. This is an equivalent to a 4-6-4 in the Whyte notation. The PRR did not have any 4-6-4 steam locomotives, so the P5s were the only 4-6-4 type locomotives owned by the PRR. The first P5s were built with box cabs. A grade crossing accident in which the crew were killed led to the substitution of a central cab to give better crash protection, a streamlined steeple type, ...

PRR Locomotive Classification
Locomotive classification on the Pennsylvania Railroad took several forms. Early on, steam locomotives were given single-letter classes. As the 26 letters were quickly assigned, that scheme was abandoned for a more complex system. This was used for all of the PRR's steam locomotives, and — with the exception of the final type bought (the E44) — all electric locomotives also used this scheme. PRR steam and electric classification A: 0-4-0 Class A was the 0-4-0 type, an arrangement best suited to small switchers. Most railroads abandoned the 0-4-0 after the 1920s, but the PRR kept it for use on small industrial branches, especially those with street trackage and tight turns. * A1 * A2 * A3 * A4 * A5s * A6 B: 0-6-0 Class B comprised the 0-6-0 type, the most popular arrangement for switchers on the PRR. * B1 * B2 * B3 * B4 * B5 - Rebuilt from class H1 and H2a 2-8-0 * B6 * B7 - Some rebuilt from class H3, H3a, and H3b 2-8-0 * B8 * B21 * B22 * ...

Raymond Loewy
Raymond Loewy ( , ; November 5, 1893 – July 14, 1986) was a French-born American industrial designer who achieved fame for the magnitude of his design efforts across a variety of industries. He was recognized for this by ''Time'' magazine and featured on its cover on October 31, 1949. He spent most of his professional career in the United States, becoming a naturalized citizen in 1938. Among his designs were the Shell, Exxon, TWA and the former BP logos, the Greyhound Scenicruiser bus, Coca-Cola vending machines and bottle redesign, the Lucky Strike package, Coldspot refrigerators, the Studebaker Avanti and Champion, and the Air Force One livery. He was engaged by equipment manufacturer International Harvester to overhaul its entire product line, and his team also assisted competitor Allis-Chalmers. He undertook numerous railroad designs, including the Pennsylvania Railroad GG1, S-1, and T1 locomotives, the color scheme and Eagle motif for the first streamliners of ...

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 or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a 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 locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Streamliner
A streamliner is a vehicle incorporating wikt:streamline, streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "High-speed rail, bullet trains". Less commonly, the term is applied to fully Bicycle fairing, faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In Land speed record, land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels. Trains Before World War II Europe The first high-speed streamliner in Germany was the "Schienenzeppelin", an experimental propeller driven single car, built in 1930. On 21 June 1931, the car set a speed record of on a run between Berlin and Hamburg. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amtrak
The National Railroad Passenger Corporation, Trade name, doing business as Amtrak () , is the national Passenger train, passenger railroad company of the United States. It operates inter-city rail service in 46 of the 48 contiguous United States, contiguous U.S. States and nine cities in Canada. ''Amtrak'' is a portmanteau of the words ''America'' and ''trak'', the latter itself a sensational spelling of ''track''. Founded in 1971 as a quasi-public corporation to operate many U.S. passenger rail routes, Amtrak receives a combination of state and federal subsidies but is managed as a for-profit corporation, for-profit organization. The United States federal government, through the United States Secretary of Transportation, Secretary of Transportation, owns all the company's Issued shares, issued and Shares outstanding, outstanding preferred stock. Amtrak's headquarters is located one block west of Washington Union Station, Union Station in Washington, D.C. Amtrak serves more th ...

AAR Wheel Arrangement
The AAR wheel arrangement system is a method of classifying locomotive (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. The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates Bogie, trucks or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of ...

Penn Central Transportation Company
The Penn Central Transportation Company, commonly abbreviated to Penn Central, was an American class I railroad that operated from 1968 to 1976. Penn Central combined three traditional corporate rivals (the Pennsylvania, New York Central and the New York, New Haven and Hartford railroads), all united by heavy service into the New York metropolitan area and (to a lesser extent) New England and Chicago. The new company failed barely two years after formation, the largest bankruptcy in U.S. history at the time. The Penn Central's railroad assets were nationalized into Conrail along with the other bankrupt northeastern roads; its real estate and insurance holdings successfully reorganized into American Premier Underwriters. History Pre-merger The Penn Central railroad system developed in response to challenges facing northeastern American railroads during the late 1960s. While railroads elsewhere in North America drew revenues from long-distance shipments of commodities suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Jersey Transit
New Jersey Transit Corporation, branded as NJ Transit, and often shortened to NJT, is a state-owned public transportation system that serves the U.S. state of New Jersey, along with portions of New York State and Pennsylvania. It operates bus, light rail, and commuter rail services throughout the state, connecting to major commercial and employment centers both within the state and in the adjacent major cities of New York and Philadelphia.

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Whyte Notation
Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives (in the latter case also for diesel and electric locomotives), but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers being separated by dashes. For example, a locomotive with two leadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
