PKP Class SM15
The SM15 (factory designation 12D) is a Polish diesel shunter used by PKP and industry — where it carried the designation Ls750H. It is based on the Soviet ТГМ3 (TGM3) locomotive. History Between the years 1963–1966, a total of 56 locomotives had been produced — 27 of which were used by PKP. Of the latter 27, the first two units (SM15-01 and SM15-02) were built at the Людиновский тепловозостроительный завод (en: Lyudinovo Diesel Locomotive Factory) and exported to Poland. Production then resumed at the Fablok factory in Chrzanów where the remaining 25 units, earmarked for PKP, were built. The newly built SM15s were assigned to the depot in Kraków Płaszów, before being withdrawn from service in the late 1960s and early 1970s, when the SM42 series replaced them. Despite their relatively short operational history, the engineers who drove the locomotives remember them as being very powerful machines. Technical data The S ...

Warsaw Railway Museum
The Stacja Muzeum is located at the former Warsaw Główna PKP railway terminus and is very close to the Warszawa Ochota railway station. The museum's exhibits are divided into permanent and temporary collections — the latter being displayed inside the museum's galleries. The permanent collection consists of historic rolling stock that is displayed on the tracks outside, including one of the few remaining armoured railway trains in Europe. The museum also contains a library which houses many books on the subject of Polish railways. During the interwar period the museum's headquarters were located at Nowy Zjazd Street. The museum was reestablished at the present site, as Railway Museum in Warsaw (), in 1972. On 30 July 2009, PKP S.A. the Polish state railway company served notice to quit on the Museum authorities requiring them to vacate their current location by 31 August 2009. However, as of May 2015, the museum remained in place and open to the public. The museum was di ... [...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] |
Diesel-hydraulic Locomotives
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Railway Locomotives Introduced In 1963
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 facilit ...

Tarnowskie Góry
Tarnowskie Góry (German: ''Tarnowitz''; szl, Tarnowske Gōry) is a town in Silesia, southern Poland, located in the Silesian Highlands near Katowice. On the south it borders the Upper Silesian Metropolitan Union, a megalopolis, the greater Silesian metropolitan area populated by about 5,294,000 people. The population of the town is 61,842 (2021). As of 1999, it is part of Silesian Voivodeship, previously Katowice Voivodeship. The Historic Silver Mine of Tarnowskie Góry, a UNESCO World Heritage Site is located in the town. Names and etymology The name of Tarnowskie Góry is derived from ''Tarnowice'', name of a local village and word ''góry'' which in Old Polish meant "mines". In a Prussian document from 1750 (published in the Polish language in Berlin by Frederick the Great 712–1786, the town is mentioned, among other Silesian towns, as "Tarnowskie Góry". The German name ''Tarnowitz'' was introduced in the late 18th century, after the Third Silesian War (between Austr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monument
A monument is a type of structure that was explicitly created to commemorate a person or event, or which has become relevant to a social group as a part of their remembrance of historic times or cultural heritage, due to its artistic, historical, political, technical or architectural importance. Some of the first monuments were dolmens or menhirs, megalithic constructions built for religious or funerary purposes. Examples of monuments include statues, (war) memorials, historical buildings, archaeological sites, and cultural assets. If there is a public interest in its preservation, a monument can for example be listed as a UNESCO World Heritage Site. Etymology It is believed that the origin of the word "monument" comes from the Greek ''mnemosynon'' and the Latin ''moneo'', ''monere'', which means 'to remind', 'to advise' or 'to warn', however, it is also believed that the word monument originates from an Albanian word 'mani men' which in Albanian language means 'remembe ...

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.

Hydraulics
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydromechanics
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasma (physics), plasmas) and the forces on them. It has applications in a wide range of disciplines, including mechanical engineering, mechanical, aerospace engineering, aerospace, civil engineering, civil, chemical engineering, chemical and biomedical engineering, geophysics, oceanography, meteorology, astrophysics, and biology. It can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a ''macroscopic'' viewpoint rather than from ''microscopic''. Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly 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 SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...
