EMD MRS-1
The EMD MRS-1 is a type of diesel-electric locomotive built by General Motors Electro-Motive Division for the United States Army Transportation Corps (USATC) in 1952. They were built with multigauge trucks and to a narrow loading gauge for service anywhere in the world in the event of war. Thirteen of the locomotives were built, with serial numbers 15873–15885. At almost $500,000 each in 1952 dollars, more than three times the price of a standard locomotive of the period, these were very expensive locomotives. Declared un-needed for wartime operations in about 1970, they were then used on various military bases around the United States, with some serving on the Alaska Railroad. Five locomotives are preserved, three currently in operating condition. History Development The Korean War and the intensification of the Cold War at the beginning of the 1950s caused the USATC to consider what it might need for a new land war in Europe. They came up with a requirement for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alco RS-3
The ALCO RS-3 is a , B-B diesel-electric locomotive manufactured from May 1950 to August 1956 by American Locomotive Company (ALCO) and its subsidiary Montreal Locomotive Works (MLW). A total of 1,418 were produced: 1,265 for American railroads, 98 for Canadian railroads, 48 for Brazilian railroads, and seven for Mexican railroads. The successor to the RS-1 and RS-2, the RS-3 was built with a single 12-cylinder ALCO Model 244 engine. The RS-3 greatly resembled the design and appearance of its predecessor, but had 100 more hp (1,600 hp) and some changes to the fuel system and body shape. Some had their engines replaced with more reliable EMD 567B engines, becoming RS-3ms. Much like the RS-1, many RS-3s served for decades; some are still in use as of 2022. Variants RSC-3: an RS-3 that used 3-axle trucks instead of 2-axle trucks. The middle axle on each truck was unpowered. This variant was designed for service on light track, as the extra axles better spread the weight o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iberian Gauge
Iberian gauge ( es, ancho ibérico, trocha ibérica, pt, bitola ibérica) is a track gauge of , most extensively used by the railways of Spain and Portugal. This is the second-widest gauge in regular use anywhere in the world. The Indian gauge, , is wider. As finally established in 1955, the Iberian gauge is a compromise between the similar, but slightly different, gauges adopted as respective national standards in Spain and Portugal in the mid-19th century. The main railway networks of Spain were initially constructed to a gauge of six Castilian feet. Those of Portugal were instead built to a and later railways to a gauge of five Portuguese feet – close enough to allow interoperability with Spanish railways. Standard gauge Since the beginning of the 1990s new high-speed passenger lines in Spain have been built to the international standard gauge of , to allow these lines to link to the European high-speed network.

Iberian Peninsula
The Iberian Peninsula (), ** * Aragonese and Occitan: ''Peninsula Iberica'' ** ** * french: Péninsule Ibérique * mwl, Península Eibérica * eu, Iberiar penintsula also known as Iberia, is a peninsula in southwestern Europe, defining the westernmost edge of Eurasia. It is principally divided between Spain and Portugal, comprising most of their territory, as well as a small area of Southern France, Andorra, and Gibraltar. With an area of approximately , and a population of roughly 53 million, it is the second largest European peninsula by area, after the Scandinavian Peninsula. Name Greek name The word ''Iberia'' is a noun adapted from the Latin word "Hiberia" originating in the Ancient Greek word Ἰβηρία ('), used by Greek geographers under the rule of the Roman Empire to refer to what is known today in English as the Iberian Peninsula. At that time, the name did not describe a single geographical entity or a distinct population; the same name was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a Federation, federal union of Republics of the Soviet Union, fifteen national republics; in practice, both Government of the Soviet Union, its government and Economy of the Soviet Union, its economy were highly Soviet-type economic planning, centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian Soviet Federative Socialist Republic, Russian SFSR. Other major cities included Saint Petersburg, Leningrad (Russian SFSR), Kyiv, Kiev (Ukrainian Soviet Socialist Republic, Ukrainian SSR), Minsk (Byelorussian Soviet Socialist Republic, Byelorussian SSR), Tas ...

Broad Gauge
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the used by standard-gauge railways. Broad gauge of , commonly known as Russian gauge, is the dominant track gauge in former Soviet Union (CIS states, Baltic states, Rail transport in Georgia (country), Georgia and Ukraine), Rail transport in Mongolia, Mongolia and Rail transport in Finland, Finland. Broad gauge of , commonly known as Irish Gauge, is the dominant track gauge in Ireland, and the Australian states of Rail transport in Victoria, Victoria and Railways in Adelaide, Adelaide. Broad gauge of , commonly known as Iberian gauge, is the dominant track gauge in Spain and Portugal. Broad gauge of , commonly known as Indian gauge, is the dominant track gauge in Indian Railways, India, Pakistan Railways, Pakistan, Bangladesh, Sri Lanka Railways, Sri Lanka, Rail transport in Argentina, Argentina, Empresa de los Ferrocarriles del Estado, Chile, and on Bay Area Rapid Transit, BAR ...

Indian Gauge
, a broad gauge, is the track gauge used in India, Pakistan, western Bangladesh, Sri Lanka, Argentina, Chile, and on BART in San Francisco, United States. In North America, it is called Indian Gauge, Provincial, Portland, or Texas gauge. In Argentina, it is known as "trocha ancha" (Spanish for ''broad gauge''). In the Indian subcontinent it is simply known as "broad gauge". Elsewhere it is known as Indian gauge. It is the widest gauge in regular passenger use anywhere in the world. Asia India In India, the initial freight railway lines were built using standard gauge. In the 1850s, the Great Indian Peninsula Railway adopted the gauge of for the first passenger railway in India between Bori Bunder and Thane.Indian Railways: Some Fascinating Facts“Train Atlas” ''Train Atlas'', Indian Railways, 2003 This was then adopted as the standard for the nationwide network.

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structure Gauge
A structure gauge, also called the minimum clearance outline, is a diagram or physical structure that sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. It specifies the height and width of platforms, tunnels and bridges, and the width of the doors that allow access to a warehouse from a rail siding. Specifications may include the minimum distance from rail vehicles to railway platforms, buildings, electrical equipment boxes, signal equipment, third rails or supports for overhead lines. A related but separate gauge is the loading gauge: a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. The difference between these two gauges is called the clearance. The specified amount of clearance makes allowance for wobbling of rail vehicles at speed; consequently, in some circumstances a train may be permitted to go past a restricted clearance at very slow speed ...

Bogie
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of Geopolitics, geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term ''Cold war (term), cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary Allies of World War II, alliance and victory against Nazi Germany and Empire of Japan, Imperial Japan in 1945. Aside from the Nuclear arms race, nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, Cold War espionage, espionage, far-reaching Economic sanctions, embargoes, rivalry at sports events, and technolog ...
