Russian Locomotive Class E El-2
The E el-2 (Cyrillic script: Ээл2) was a Soviet diesel-electric locomotive designed by Yury Lomonosov and built in Germany. The work was started by Hohenzollern Locomotive Works in Germany but, for political reasons, it was later transferred to Maschinenfabrik Esslingen. The locomotive was completed in 1924. On January 20, 1925 it was transferred to the USSR and presented to the press and officials. The rest of that year it spent on several mainline routes and then worked mostly between Moscow and Kursk, Russian SFSR, but later moved to Ashkhabad (Ashgabat, Turkmenistan). Despite some technical troubles in the early years of service, it underwent several modifications and lasted until 1954, running about a million kilometers in total. Powertrain The prime mover was an MAN submarine-type diesel engine, weighing 26 tonnes, and there were five traction motors, one for each driving axle.

Ashgabat
Ashgabat or Asgabat ( tk, Aşgabat, ; fa, عشقآباد, translit='Ešqābād, formerly named Poltoratsk ( rus, Полтора́цк, p=pəltɐˈratsk) between 1919 and 1927), is the capital and the largest city of Turkmenistan. It lies between the Karakum Desert and the Kopetdag mountain range in Central Asia, near the Iran-Turkmenistan border. The city was founded in 1881 on the basis of an Ahal Teke tribal village, and made the capital of the Turkmen Soviet Socialist Republic in 1924. Much of the city was destroyed by the 1948 Ashgabat earthquake, but has since been extensively rebuilt under the rule of Saparmurat Niyazov's "White City" urban renewal project, resulting in monumental projects sheathed in costly white marble. The Soviet-era Karakum Canal runs through the city, carrying waters from the Amu Darya from east to west. Since 2019, the city has been recognized as having one of the highest costs of living in the world largely due to Turkmenistan's inflation ...

Railway Locomotives Introduced In 1924
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 faciliti ...

Coupling
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiter, torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost. Uses Shaft couplings are used in machinery for several purposes. A primary function is to transfer power from one end to another end (ex: motor transfer power to pump through coupling). Other common uses: * To alter the vibration characteristics of rotating units * To connect the driving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station. Weight distribution The power unit rep ...

Kursk
Kursk ( rus, Курск, p=ˈkursk) is a city and the administrative center of Kursk Oblast, Russia, located at the confluence of the Kur, Tuskar, and Seym rivers. The area around Kursk was the site of a turning point in the Soviet–German struggle during World War II and the site of the largest tank battle in history. Geography Urban layout Kursk was originally built as a fortress city, on a hill dominating the plain. The settlement was surrounded on three sides by steep cliffs and rivers. From the west, the Kur river, from the south and east, the Tuskar river, and from the north, forest thickets approached it. By 1603, Kursk had become a large military, administrative and economic center of a vast territory in the south of the country. The new fortress was built under the leadership of the governor Ivan Polev and Nelyub Ogaryov. The Kursk fortress was given a particularly important role, since in these places the Crimean Tatars, who made regular raids on Russia, traditio ...

Hohenzollern Locomotive Works
The Hohenzollern Locomotive Works (Aktiengesellschaft für Lokomotivbau Hohenzollern) was a German locomotive-building company which operated from 1872 to 1929. The Hohenzollern works was a manufacturer of standard gauge engines and about 400 fireless locomotives as well as diesel locomotives of various rail gauges. The company was founded on 8 June 1872 in Grafenberg near Düsseldorf. The firm produced around 4,600 locomotives. After the increasingly critical situation in the German locomotive building industry around 1929 the works was closed in November 1929. The Hohenzollern AG had hoped in vain for follow-on orders for the DRG Class 80 from the Deutsche Reichsbahn-Gesellschaft (DRG). Locomotive number 80 030 in the Bochum-Dahlhausen Railway Museum was one of the last that had been built by the Lokomotivbau Hohenzollern and is preserved today in photograph-grey livery. The last locomotives had left the factory in September 1929; it was then immediately torn down. Fire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
