HNJ Mb
The Mb, later G12 class of Halmstad–Nässjö Järnväg (HNJ), known after nationalization in 1945 as the E9 class of the Swedish State Railways (SJ), was a type of steam locomotive built primarily for freight traffic. They were the basis for the nearly identical SJ E10 class. History Three Mb class three-cylinder 4-8-0 locomotives were built by NOHAB for HNJ in 1931, based on an older type, the 2-8-0 M class built in Germany in 1922. HNJ changed their type designations the year after, and the Mb class became the G12 class, where G meant that they were intended for freight trains (Swedish: ''godståg''). Three more G12 class locomotives were built in 1936. Despite their designation the locomotives were also used in passenger trains. They remained on the HNJ network after nationalization in 1945, but were also used on the line between Alvesta and Borås. SJ referred to the type as the E9 class. They were in service until 1959, and were then placed in reserve. They were sc ...

NOHAB
NOHAB (Nydqvist & Holm AB) was a manufacturing company based in the city of Trollhättan, Sweden. History The company was founded by Antenor Nydqvist, Johan Magnus Lidström and Carl Olof Holm in 1847 as ''Trollhättans Mekaniska Verkstad'' as a manufacturer of turbines for hydraulic power plants. In 1865, the company made its first steam locomotive and in 1912 the 1,000th locomotive steamed out of the factory. In Nohab's anniversary book "The Thousand Locomotive" from 1912, it's mentioned that the company also manufactured davits for Titanic's lifeboats. In 1916 the company was reconstituted as a limited company and became NOHAB. In 1920, NOHAB received an order of 1000 locomotives from Soviet Russia. Only 500 were delivered between 1921 and 1924. In 1924, Nohab built three steam locomotives, 4-6-0 ones for with the respective builder's plates #1727, #1728 and #1729 for Estrada de Ferro Rio d'Ouro in the state of Rio de Janeiro (Brazil). According to E.F. Rio d'Ouro's su ...

Coast-to-Coast Line
The Coast-to-Coast Line ( sv, Kust till kust-banan) is a long Y-shaped electric railway line between Gothenburg via Emmaboda to Kalmar and Karlskrona in southern Sweden. History The line was built as five different railways: from Gothenburg to Borås, from Borås to Alvesta, from Växjö to Alvesta, from Karlskrona to Växjö and the Kalmar Line. The lines were nationalized in 1940 and 1941 and operations taken over by the Swedish State Railways. By then, the section from Gothenburg to Borås had been electrified. The remaining sections were electrified between 1954 and 1962: from Alvesta to Växjö in 1953, from Växjö to Kalmar in 1954 and from Borås to Alvesta in 1962. SJ T41 locomotives were the most common during the diesel era, and replaced by SJ D and SJ Da locomotives after electrification. The services were also provided with SJ X9 multiple units and later SJ F locomotives. From the 1980s, the line was served by the SJ Rc locomotives. The section from Gothenburg to ...

Steam Locomotives Of Sweden
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 ...

Norrland
Norrland (, "Northland", originally ''Norrlanden'' or "the Northlands") is the northernmost, largest and least populated of the three traditional lands of Sweden, consisting of nine provinces. Although Norrland does not serve any administrative purposes, it continues to exist as a historical, cultural, and geographic region; it is often referred to in everyday language, e.g., in weather forecasts. Several related Norrland dialects form a distinct subset of dialects of the Swedish language separate from those to its south. Norrland consists of the majority of the Swedish landmass at about 60% of the land area, but only has about 12% of the country's population. Its largest city is Umeå, while the other four county seats are Gävle, Sundsvall, Östersund and Luleå. The largest non-capitals are Skellefteå and Örnsköldsvik while Kiruna is the largest town of the vast Lapland province in the far north. Sweden's highest mountain Kebnekaise and deepest lake of Hornavan are ...

Inland Line
The Inland Line ( sv, Inlandsbanan) is a railway line between Kristinehamn and Gällivare in Sweden. It runs through the central parts of northern Sweden, and was built between 1908 and 1937. History There were several reasons for constructing the railway. The original main line to the north of Sweden ran relatively near the east coast, but inland connections were poor to non-existent; the inland regions, rich in natural resources (mainly timber) needed opening up. However, there was a strategic aspect to be considered; should Sweden be invaded from the east (which at the time was a serious possibility) the belligerents would certainly try to cut the main line to the north as quickly as possible; thus a second reserve route further inland was deemed highly important. In 1907 the Riksdag decided that the first link between Östersund and Ulriksfors was to be built. The next stage Ulriksfors–Volgsjö (today Vilhelmina) was conceived in 1911; the year after that the Sveg-Brunflo ...

Borås
Borås ( , , ) is a city (officially, a locality) and the seat of Borås Municipality, Västra Götaland County, Sweden. It had 66,273 inhabitants in 2010. Geography Borås is located at the point of two crossing railways, among them the railway between Gothenburg and Kalmar, and is often considered the Swedish city gaining the most from the nationwide railway system laid between 1870 and 1910. History The city of Borås received its privileges in 1621 by King Gustav II Adolf. The reason was to give local pedlars a legal place for vending their merchandise (and for the government the ability to collect taxes on this trade). The city developed soon after it was founded. After a century it had increased to over 2,000 inhabitants. Borås has been ravaged by fires four times: in 1681, 1727, 1822 and 1827. The Caroli church is the oldest of Borås's buildings, and has withstood all fires. In its 2017 report, Police in Sweden placed the Norrby, Hässleholmen and Hulta dis ...

Swedish Language
Swedish ( ) is a North Germanic language spoken predominantly in Sweden and in parts of Finland. It has at least 10 million native speakers, the fourth most spoken Germanic language and the first among any other of its type in the Nordic countries overall. Swedish, like the other Nordic languages, is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era. It is largely mutually intelligible with Norwegian and Danish, although the degree of mutual intelligibility is largely dependent on the dialect and accent of the speaker. Written Norwegian and Danish are usually more easily understood by Swedish speakers than the spoken languages, due to the differences in tone, accent, and intonation. Standard Swedish, spoken by most Swedes, is the national language that evolved from the Central Swedish dialects in the 19th century and was well established by the beginning of the 20th century. While distinct regional varieties ...

4-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler. Overview The first locomotive is believed to have been the ''Centipede'', a tender locomotive built by Ross Winans in 1855 for the Baltimore and Ohio Railroad in the United States of America, where it remained in service for nearly twenty years. It appears to have been delivered in a cab-forward type of configuration that was modified to a Camel configuration in 1864.Carling, D. Rock (1972). ''4-8-0 Tender Locomotives''. Drake Publishers Inc. On a Camel locomotive the cab was mounted atop the boiler, unlike the later Camelback locomotive whose cab straddled the boiler and that first appeared around 1877. The nickname Mastodon is of ...

2-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s ''Consolidation'', the name of the first 2-8-0.White, John H. Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York: Dover Publications, p. 65. The notation 2-8-0T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in side-tanks mounted on the engine rather than in an attached tender. The Consolidation represented a notable advance in locomotive power. After 1875, it became "the most popular type of freight locomotive in the United States and was built in greater quantities than any other si ...

SJ E10
The Swedish State Railways class E10 was a type of steam locomotive which was used for freight traffic. Ten locomotives were built in 1947 as a slightly modified version of the older E9 class. They were used mainly on the Inland Line, before being placed in the strategic reserve, where some remained until 1990; five of them have been preserved. History In the 1940s the Swedish State Railways (SJ) saw a need for modern steam locomotives for freight traffic on the Inland Line and in southern Norrland. When the private railway company '' Halmstad–Nässjö Järnväg'' (HNJ) was nationalized in 1945, their G12 class three-cylinder 4-8-0 locomotives became the E9 class of SJ. Impressed by these smooth-running locomotives with high traction and a low axle load, SJ ordered ten E10 locomotives from NOHAB, based on the E9. The E10 locomotives, delivered in 1947, were the last large steam locomotives built for the Swedish railways. The class differed from the E9 by having roller bea ...
