Oldenburg B
The steam locomotives of Oldenburg Class B of the Grand Duchy of Oldenburg State Railways were built in the early 1900s for working the metre gauge network on the German island of Wangerooge. Initially one example was ordered in 1904 from Freudenstein & Co. in Berlin. This tank engine weighed only 9.4 t when empty and could carry 1.2 m³ of water and 0.35 tonnes of coal. It had a well tank and the coal bunkers were on the left and right hand side of the boiler. The engine drove the second axle and the locomotive had the number 3. In 1910 a somewhat heavier and larger locomotive was ordered from Hanomag. It weighed in at 12.2 tonnes (service weight). Because this engine acquitted itself well, in 1913 another one was ordered. These two locomotives were given numbers 4 and 5. After the formation of the Reichsbahn the engines were taken over, classified as DRG Class 99.02 and given the numbers 99 021–023. In 1942 locomotives 99 021 and 99 022 had to be handed over for wartime du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturer
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final produc ...

Piston Stroke
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

Wangerooge
Wangerooge is one of the 32 Frisian Islands in the North Sea located close to the coasts of the Netherlands, Germany and Denmark. It is also a municipality in the district of Friesland in Lower Saxony in Germany. Wangerooge is one of the East Frisian Islands. It is the easternmost and smallest of the inhabited islands in this group (according to some other measurements, Baltrum is the smallest) and the only one that belonged to the historical district of Oldenburg between 1815 and 1947, whereas Borkum, Juist, Norderney, Baltrum, Langeoog and Spiekeroog always belonged to the county of Ostfriesland. As of the census of 2004, the island has 1,055 inhabitants. Especially in summer the island accommodates more than 7,000 visitors a day. Wangerooge is separated from the island of Spiekeroog by a gat known as the Harle. The island is attractive to tourists due to the beaches, various recreation facilities and its relaxed atmosphere. The island's slogan, visible on a sign at the harb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Front (World War II)
The Eastern Front of World War II was a Theater (warfare), theatre of conflict between the European Axis powers against the Soviet Union (USSR), Polish Armed Forces in the East, Poland and other Allies of World War II, Allies, which encompassed Central Europe, Eastern Europe, Northern Europe, Northeast Europe (Baltic states, Baltics), and Southeast Europe (Balkans) from 22 June 1941 to 9 May 1945. It was known as the Great Patriotic War (term), Great Patriotic War in the Soviet Union – and still is in some of its successor states, while almost everywhere else it has been called the ''Eastern Front''. In present-day German and Ukrainian historiography the name German-Soviet War is typically used. The battles on the Eastern Front of the Second World War constituted the largest military confrontation in history. They were characterised by unprecedented ferocity and brutality, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, expos ...

Deutsche Reichsbahn
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Well Tank
A tank locomotive or tank engine is a steam locomotive that carries its water in one or more on-board water storage tanks, tanks, instead of a more traditional tender (rail), tender. Most tank engines also have Fuel bunker, bunkers (or fuel tanks) to hold fuel; in a #Tender-tank, tender-tank locomotive a Tender (rail), tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for Shunting (rail), shunting and shorter-distance Main line (railway), main line duties. Tank locomotives have #Advantages and disadvantages, advantages and disadvantages compared to traditional locomotives that required a separate Tender (rail), tender to carry needed water and fuel.

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wangerooge Island Railway
The single track Wangerooge Island Railway (''Wangerooger Inselbahn'') is an unelectrified narrow gauge railway with a track gauge of located on the East Frisian Islands, East Frisian island of Wangerooge off the northwestern coast of Germany. It is the most important means of transport on the island and is the only narrow gauge railway operated today by the Deutsche Bahn. History From 1897 to 1920 The Wangerooge Island Railway was opened in 1897 with its present-day track gauge of . Its operator was the Grand Duchy of Oldenburg State Railways (''Großherzoglich Oldenburgische Eisenbahn'' or ''GOE''). It was worked from the outset by steam locomotives, and not as a Horsecar, horse-drawn railway as on several neighbouring islands. The line led from the newly built pier in the southwest of the island to the middle of the island village, or ''Inseldorf'', in the centre of the island. A train needed about 20 minutes to negotiate the 3.5 kilometre long route at a top speed o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metre Gauge
Metre-gauge railways are narrow-gauge railways with track gauge of or 1 metre. The metre gauge is used in around of tracks around the world. It was used by European colonial powers, such as the French, British and German Empires. In Europe, large metre-gauge networks remain in use in Switzerland, Spain and many European towns with urban trams, but most metre-gauge local railways in France, Germany and Belgium closed down in the mid-20th century, although many still remain. With the revival of urban rail transport, metre-gauge light metros were established in some cities, and in other cities, metre gauge was replaced by standard gauge. The slightly-wider gauge is used in Sofia. Examples of metre-gauge See also * Italian metre gauge * Narrow-gauge railways A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Duchy Of Oldenburg State Railways
The Grand Duchy of Oldenburg Railway (''Großherzoglich Oldenburgische Eisenbahn or GOE'') was the railway company that was run as a state railway for the Grand Duchy of Oldenburg (''Großherzogtum Oldenburg''), part of the German Empire. History Compared with the other states in the German Empire, Oldenburg's first railway line arrived relatively late. In this sparsely populated and economically poor area, the construction of railways appeared for a long while to be unsustainable due to the financial costs. In addition, the various ideas of its neighboring states, Hanover and Prussia prevented railway projects from coming to fruition for a long time. Finally in 1864 a treaty was agreed between Prussia and Oldenburg over the construction of a railway line from Bremen to Oldenburg. At the same time Prussia committed itself to building a railway line from Heppens – later Wilhelmshaven – to Oldenburg (the Wilhelmshaven–Oldenburg line). The Grand Ducal Railway Commission, set ...
