Baldwin Centipede
The Baldwin DR-12-8-1500/2 (known informally as the ''Centipede'') was the Baldwin Locomotive Works' first serious attempt at a production road A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. Th ... diesel locomotive. The Baldwin type designation was ''DR-12-8-1500/2'', meaning Diesel Road locomotive, with 12 Wheelset (rail transport), axles (8 of which were driven), and two engines of each. The trucks were configured in a AAR wheel arrangement#2-D.2BD-2, 2-D+D-2 wheel arrangement. The nickname came from the numerous axles set in a nearly unbroken line, much like the legs of a centipede. History Built between December 1945 and July 1948, the "Baldwin DR-4-4-15, Babyface" design reflected Baldwin steam locomotive, steam and electric locomotive practice. The carbody rode on two massive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Railroad
The Pennsylvania Railroad ( reporting mark PRR), legal name as 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. At its peak in 1882, the Pennsylvania Railroad was the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Over its existence, Pennsylvania Railroad 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, Topeka & Santa Fe railroads. Its only formidable rival was the New York Centra ... [...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] |
V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baldwin 4-8+8-4-750/8-DE
The Baldwin 4-8+8-4 750/8DE1 was the Baldwin Locomotive Works' first attempt at building a road diesel locomotive. The trucks were configured in a 2-D+D-2 wheel arrangement. Only a single test unit was built. In 1943 Baldwin built an experimental "Centipede" as a demonstrator unit, which was assigned road #6000. The uniquely styled unit, with its upright, aggressive prow, was to be powered with eight model 408-series V8 8LV diesel engines (which would have produced ), though only four were actually installed. The locomotive's running gear design reflected Baldwin steam and electric locomotive practice. The carbody rode on two massive articulated cast steel half-frames cast by General Steel Castings, linked at the middle with a hinged joint. Unpowered four-wheel trucks at each end guided the locomotive through curves for stability at speed. The locomotive utilized unique "power packages", each consisting of an engine, generator, radiator, electrical cabinet, and other auxiliarie ...

Seaboard Air Line
The Seaboard Air Line Railroad , known colloquially as the Seaboard Railroad during its time, was an American railroad that existed from April 14, 1900, until July 1, 1967, when it merged with the Atlantic Coast Line Railroad, its longtime rival, to form the Seaboard Coast Line Railroad. Its predecessor railroads dated from the 1830s and reorganized extensively to rebuild after the American Civil War, and by 1900 had merged together to form the SAL. The company was headquartered in Portsmouth, Virginia until 1958, when its main offices were relocated to Richmond, Virginia. Styling itself as "The Route of Courteous Service", Seaboard, along with its main competitors Atlantic Coast Line Railroad, Florida East Coast Railway and Southern Railway, contributed greatly to the economic development of the Southeastern United States, and particularly to that of Florida throughout the first half of the 20th century. Its trains brought vacationers to Florida from the Northeast and car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bank Engine
A bank engine (United Kingdom/Australia) (colloquially a banker), banking engine, helper engine or pusher engine (North America) is a railway locomotive that temporarily assists a train that requires additional power or traction to climb a gradient (or ''bank''). Helpers/bankers are most commonly found in mountain divisions (called "helper districts" in the United States), where the ruling grade may demand the use of substantially greater motive power than that required for other grades within the division. Historic practice Helpers/bankers were most widely used during the age of steam, especially in the American West, where significant grades are common and trains are long. The development of diesel-electric or electric locomotives has eliminated the everyday need for bankers/helpers in all but a few locations. With the advent of dynamic brakes on electric or diesel-electric locomotives, helpers/bankers can also be used to provide more braking force on long downhill gradi ...

Planned Maintenance
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure and supporting utilities in industrial, business, and residential installations. Terms such as "predictive" or "planned" maintenance describe various cost-effective practices aimed at keeping equipment operational; these activities occur either before or after a potential failure. Definitions Maintenance functions can be defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or r ...

Ferrocarriles Nacionales De México
''Ferrocarriles Nacionales de México'' (better known as N de M and after 1987 as Ferronales or FNM) or ''National Railways of Mexico'' was Mexico's state owned railroad company from 1938 to 1998, and prior to 1938 (dating from the regime of Porfirio Díaz), a major railroad controlled by the government that linked Mexico City to the major cities of Ciudad Juárez, Nuevo Laredo and Matamoros, Tamaulipas, Matamoros on the US-Mexico border, U.S. border. The first trains to Nuevo Laredo from Mexico City began operating in 1903. History The beginnings of rail transport in Mexico date back to the concessions granted by Maximilian I of Mexico, mostly to foreign companies, and continued by Benito Juárez. In 1898, José Yves Limantour proposed a system of concessions of the railway companies on the future lines to be built from 1900. That same year the Secretariat of Finance and Public Credit, Secretariat of the Treasury promulgated the first General Railway Law. This law establishe ...
