PRR H6
The Pennsylvania Railroad's class H6, H6a, and H6b steam locomotives were of the 2-8-0 "Consolidation" freight type, the most numerous class on the railroad with 1,707 units and the second most prolific 2-8-0 class in North America, with the USATC S160 class rostering 88 units more. The three subclasses differed as follows: In the 1920s, 699 H6a and H6b had superheaters added, and cylinder size increased from to . These rebuilt units were reclassified to H6sa and H6sb. Class H6 were used throughout the system as mainline freight haulers, on local freights, and as switchers in yards. They were frequently seen double- and tripleheading long freight trains up the steep grades on the Pennsy.Westing, Fred. Pennsy Steam and Semaphores. Superior Publishing During the period when the PRR was building the H-6 class, the railroad had effective stock control of the Baltimore and Ohio Railroad, and installed a PRR vice-president Leonor F. Loree, as president of the B&O. Subsequently, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives On The National Register Of Historic Places In Pennsylvania
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolling Stock Of Manchukuo
Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as ''pure rolling''. By definition, there is no sliding when there is a frame of reference in which all points of contact on the rolling object have the same velocity as their counterparts on the surface on which the object rolls; in particular, for a frame of reference in which the rolling plane is at rest (see animation), the instantaneous velocity of all the points of contact (e.g., a generating line segment of a cylinder) of the rolling object is zero. In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Nevertheless, the resulting rolling resistance is much lower than sliding friction, and thus, rolli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives Of China
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

Lima Locomotives
Lima ( ; ), originally founded as Ciudad de Los Reyes (City of The Kings) is the capital and the largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín Rivers, in the desert zone of the central coastal part of the country, overlooking the Pacific Ocean. Together with the seaside city of Callao, it forms a contiguous urban area known as the Lima Metropolitan Area. With a population of more than 9.7 million in its urban area and more than 10.7 million in its metropolitan area, Lima is one of the largest cities in the Americas. Lima was named by natives in the agricultural region known by native Peruvians as ''Limaq''. It became the capital and most important city in the Viceroyalty of Peru. Following the Peruvian War of Independence, it became the capital of the Republic of Peru (República del Perú). Around one-third of the national population now lives in its metropolitan area. The city of Lima is considered to be the political, cultural, fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
