SF Hydro
SF ''Hydro'' was a Norwegian steam powered railway ferry that operated in the first half of the 20th century on Lake Tinn in Telemark. It connected with the Rjukan Line and Tinnoset Line, at Mæl and Tinnoset, operating between 1914 and 1944. The combined track and ferry service was primarily used to transport raw materials and fertilizer from Norsk Hydro's factory at Rjukan to the port in Skien. It was the target of a Norwegian operation on 20 February 1944, when resistance fighters sank the ferry in the deepest part of Lake Tinn to prevent Nazi Germany from receiving heavy water. Usage The railway ferries operated a route connecting the Tinnoset Line and Rjukan Line. Transport included both railway cars, carrying primarily fertilizer, potassium nitrate and ammonia from Norsk Hydro, as well as passengers. ''Hydro'' was the second ship delivered for the service. The first ship, SF ''Rjukanfos'', was delivered in 1909 but proved too small for the service. ''Hydro'' was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norsk Transport
Hydro Transport AS was a railway company, railway- and List of ship companies, shipping company responsible for the transport of chemicals from Norsk Hydro Rjukan. A subsidiary of Norsk Hydro, the company was founded in 1907, operations ceased in 1991, while the company became defunct at the end of 2009. To transport the products to the coastal port at Skien, Norsk Hydro needed to build an extensive railway network. Cargo was stored in tank cars and transported down the Rjukan Line, Rjukanbanen to Mæl Station, Mæl, where it was transferred to the Tinnsjø railway ferry. After a ride across the lake, it was again transferred to Tinnoset Line and transported to Notodden where it was transshipped to barges and transported down the Telemark Canal. After 1919 the final stage was replaced with the Bratsberg Line; simultaneously the Tinnoset Line was nationalized and taken over by Norwegian State Railways, Norges Statsbaner.

Skien
Skien () is a city and municipality in Vestfold og Telemark county in Norway. In modern times it is regarded as part of the traditional region of Grenland, although historically it belonged to Grenmar/Skiensfjorden, while Grenland referred the Norsjø area and Bø. The administrative centre of the municipality is the city of Skien. Skien is also the capital of Vestfold og Telemark county. Skien is one of Norway's oldest cities, with an urban history dating back to the Middle Ages, and received privileges as a market town in 1358. From the 15th century, the city was governed by a 12-member council. The modern municipality of Skien was established on 1 January 1838 (see formannskapsdistrikt). The rural municipalities of Gjerpen and Solum were merged into the municipality of Skien on 1 January 1964. The conurbation of Porsgrunn/Skien is reckoned by Statistics Norway to be the seventh largest urban area in Norway, straddling an area of three municipalities: Skien municipality (abou ...

Railway Ferry At Rollag
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 facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engines
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norwegian Krone
The krone (, abbreviation: kr (also NKr for distinction); code: NOK), plural ''kroner'', is currency of the Kingdom of Norway (including Svalbard). Traditionally known as the Norwegian crown in English. It is nominally subdivided into 100 ''øre'', although the last coins denominated in øre were withdrawn in 2012. The krone was the thirteenth-most-traded currency in the world by value in April 2010, down three positions from 2007. The Norwegian krone is also informally accepted in many shops in Sweden and Finland that are close to the Norwegian border, and also in some shops in the Danish ferry ports of Hirtshals and Frederikshavn. Norwegians spent 14.1 billion NOK on border shopping in 2015 compared to 10.5 billion NOK spent in 2010. Border shopping is a fairly common practice amongst Norwegians, though it is seldom done on impulse. Money is spent mainly on food articles, alcohol, and tobacco, in that order, usually in bulk or large quantities. This is due to considerably ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Potassium Nitrate
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Car
A railroad car, railcar ( American and Canadian English), railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system (a railroad/railway). Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units. The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner, though the term has other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries " railcar" refers specifically to a self-propelled, powered, railway vehicle. Although some cars exist for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
