ČSD Class 387.0
The ČSD Class 387.0 were 4-6-2 express passenger steam locomotives operated by the Czechoslovak State Railways (Československé státní dráhy, ČSD) between 1926 and 1974. Forty-three of these pacific locomotives were built by the Škoda Works, Plzeň in five series between 1926 and 1937, intended for the heaviest long-distance express trains. History The Czechoslovak state railway looked attentively at the operating and service costs, and decided to order a three-cylinder single-expansion engine with axle load up to 16 tonnes, which could operate on all main lines. The result didn't exactly meet the original proposal, because of a higher axle load (17 tonnes), but the locomotive was great step forward in the construction of steam locomotives in Czechoslovakia. Design The frame is of the girder type, cast of vanadium steel. The twin-axle leading bogie has side play of ±, the rear truck of Adams type ±. The centre coupled axle, which is the driving one, has its flange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Škoda Works
The Škoda Works ( cs, Škodovy závody, ) was one of the largest European industrial conglomerates of the 20th century, founded by Czech engineer Emil Škoda in 1859 in Plzeň, then in the Kingdom of Bohemia, Austrian Empire. It is the predecessor of today's Škoda Auto, Doosan Škoda Power and Škoda Transportation companies. History 1859–1899: establishment of Škoda The noble Waldstein family founded the company in 1859 in Plzeň, and Emil Škoda bought it in 1869. It soon established itself as Austria-Hungary's leading arms manufacturer producing heavy guns for the navy, mountain guns or mortars along with the Škoda M1909 machine gun as one of its noted products. Besides producing arms for the Austro-Hungarian Army, Škoda has ever since also manufactured locomotives, aircraft, ships, machine tools, steam turbines and equipment for power utilities. In 1859, Count Wallenstein-Vartenberk set up a branch of his foundry and engineering works in Plzeň. The output of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives Of Czechoslovakia
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 ...

Railway Locomotives Introduced In 1926
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 ...

Kylchap
The Kylchap steam locomotive exhaust system was designed and patented by French steam engineer André Chapelon, using a second-stage nozzle designed by the Finnish engineer Kyösti Kylälä and known as the ''Kylälä spreader''; thus the name KylChap for this design. Construction The Kylchap exhaust consists of four stacked nozzles, the first exhaust nozzle (UK: blastpipe) blowing exhaust steam only and known as the primary nozzle, this being a Chapelon design using four triangular jets. This exhausts into the second stage, the Kylälä spreader, which mixes the exhaust steam with some of the smokebox gases; this then exhausts into a third stage, designed by Chapelon, that mixes the resulting steam/smokebox gases mixture with yet more smokebox gases. The four nozzles of this then exhaust into the fourth stage, the classic chimney (U.S.: stack) bell-mouth. Theory It was Chapelon's theory that such a multi-stage mixing and suction arrangement would be more efficient than the s ...

387 Luschna (cropped)
__NOTOC__ Year 387 ( CCCLXXXVII) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Eutropius (or, less frequently, year 1140 ''Ab urbe condita''). The denomination 387 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

ČSD Class 486
Czechoslovak State Railways (''Československé státní dráhy'' in Czech or ''Československé štátne dráhy'' in Slovak, often abbreviated to ČSD) was the state-owned railway company of Czechoslovakia. The company was founded in 1918 after the end of the First World War and dissolution of Austria-Hungary. It took over the rolling stock and infrastructure of the Imperial Royal Austrian State Railways. In 1930 Czechoslovakia had of railways: the fifth-largest network in Europe. Of these 81% were state (ČSD)-owned, and the trend was to nationalize the remaining private railways. Most of the infrastructure was concentrated in the industrial regions of the Czech lands. 87% of the railroads were single-track. 135,000 people were employed on the railways: about 1% of the population. When Nazi Germany dissolved Czechoslovakia in 1939, the Protectorate of Bohemia and Moravia formed the "Bohemian-Moravian Railway" company (in Czech ''Českomoravské dráhy-ČMD'', in Germa ...
