Soviet Locomotive Class OR23
The OR23 was a Soviet experimental locomotive built in 1949. Its cylinders were placed above the center driving axle, and had rods on both ends which transferred power to the wheels. The purpose was to balance the driving forces on the wheels, allowing the counterweights on the wheels to be smaller and reducing hammer blow on the track. The design was a failure and no further examples were built. The locomotive was never used beyond testing and was returned to its builder, the Voroshilovgrad Works, and scrapped sometime afterward.

Wilhelm Schmidt (engineer)
Wilhelm Schmidt, known as Hot Steam Schmidt (German: ''Heißdampf-Schmidt'') (1858–1924) was a German engineer and inventor who achieved the breakthrough in the development of superheated steam technology for steam engines. Wilhelm Schmidt was born in Wegeleben in the Prussian Province of Saxony on 18 February 1858. Education At school Wilhelm Schmidt had difficulties with reading, writing and arithmetic, a case of dyslexia. For example, he was unable to recite the alphabet without hesitation all his life. Nor could he memorise poetry or prose. He developed a passion for drawing, however, and for machines. Career Schmidt began his professional career as a machine fitter. He studied at the technical high school in Dresden under Gustav Zeuner. Superheated steam In 1883 he took a post as a civil engineer in Kassel, where he developed superheated steam technology to the point where it could be practically used. In 1908 he transferred his home and the base of his firm to B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Railways
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Cylinder (locomotive)
The cylinder is the power-producing element of the steam engine powering a steam locomotive. The cylinder (engine), cylinder is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were initially cast iron, but later made of steel. The cylinder casting includes other features such as (in the case of Stephenson's Rocket) valve ports and mounting feet. The last big American locomotives incorporated the cylinders as part of huge one-piece steel castings that were the Locomotive frame, main frame of the locomotive. Renewable wearing surfaces were needed inside the cylinders and provided by cast-iron bushings. The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope wit ...

Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunter locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets with wheels within each set linked together. Diameter Drivin ...

Hammer Blow
In rail terminology, hammer blow or dynamic augment is a vertical force which alternately adds to and subtracts from the locomotive's weight on a wheel. It is transferred to the track by the driving wheels of many steam locomotives. It is an out-of-balance force on the wheel (known as overbalance). It is the result of a compromise when a locomotive's wheels are unbalanced to off-set horizontal reciprocating masses, such as connecting rods and pistons, to improve the ride. The hammer blow may cause damage to the locomotive and track if the wheel/rail force is high enough. Principles The addition of extra weights on the wheels reduces the unbalanced reciprocating forces on the locomotive but causes it to be out of balance vertically creating hammer blow. Locomotives were balanced to their individual cases, especially if several of the same design were constructed (a class). Each class member was balanced for its normal operating speed. Between 40% and 50% of the reciprocating weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Rail Transport In Russia
Russia was and is the largest country in the world. Its geography of north–south rivers and east–west commerce, plus, importantly, the mostly flat terrain, made it very suited to develop railroads as the basic mode of transportation. Today Russian Railways, a state-owned railway company, is one of the biggest Railway company, railway companies in the world with 950,000 employees and a monopoly within Russia. The total length of line used by the Russian Railways is, at , one of the largest in the world, exceeded only by the United States. General history Russian Empire (1837–1917) In the early 1830s Russian inventors father and son Cherepanovs built Cherepanov steam locomotive, the first Russian steam locomotive. The first railway line was built in Russia in 1837 between Saint-Petersburg and Tsarskoye Selo, and called the Tsarskoye Selo Railway. It was long and linked the Imperial Palaces at Tsarskoye Selo and Pavlovsk, Saint Petersburg, Pavlovsk. Track gauge was 6 ...

Russian Railway Museum
The Russian Railway Museum is situated next to Baltiysky railway station in Saint Petersburg. The museum was established in 1978, its current site and exhibition opened to public on 1 November 2017. The museum utilizes the nineteenth century locomotive shed of the Peterhof Railway built in 1857–1858, however a large second exhibition building and open exhibition areas have been added. This Russian Railway Museum maintained by the Russian Railways is not to be confused with thCentral Rail Transport Museumowned by thFederal Agency for the Rail Transportand located on Sadovaya str. History In 1974, the trade union and the management of the Oktyabrskaya Railway decided to establish a museum for the employees of the enterprise. The first exhibition opened in 1978 and was located in the centre of Leningrad, on Liteyny Avenue. Later a small group of enthusiastic railway workers proposed to preserve the historical rolling stock pieces. Their proposal was met by the railway man ...

Steam Locomotives Of The Soviet Union
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it 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 vapour pressure, it can create a steam explosion. Types of steam and conversions Steam is trad ...
