Iron Ore Line
The Iron Ore Line ( sv, Malmbanan) is a long railway line between Riksgränsen and Boden in Norrbotten County, Sweden, owned by Trafikverket (the Swedish Transport Administration). The line also contains two branches, from Kiruna to Svappavaara and from Gällivare to Koskullskulle. The term is often colloquially used to also include the Ofoten Line, from Riksgränsen to Narvik in Norway, and the northernmost part of the Main Line Through Upper Norrland from Boden to Luleå. The railway from Narvik to Luleå is long. The line is dominated by the ore freight trains operated by LKAB's subsidiary Malmtrafik from their mines to the Port of Narvik and the Port of Luleå. In addition, SJ operates passenger trains and CargoNet operates container freight trains. The Iron Ore Line is single track, electrified at and has a permitted axle load of . The Swedish part of the line is the northernmost railway in Sweden and the Norwegian part outside Narvik is the northernmost railway in the ...

Malmtrafik
LKAB Malmtrafik, earlier Malmtrafik i Kiruna AB (''MTAB''), is a Swedish railway company which operates the iron ore freight trains on the Iron Ore Line and the Ofoten Line. MTAB is a wholly owned subsidiary of the mining company Luossavaara–Kiirunavaara (LKAB). In Norway, operations are handled by the subsidiary Malmtrafikk AS (MTAS). Malmtrafik hauls ore from LKAB's mines in Kiruna, Malmberget and Svappavaara to the ports of Luleå and Narvik, the latter located in Norway. The company owns 28 Iore locomotives and 750 hopper cars. Each train is 68 cars long and weighs , allowing the company to transport 33 million tonnes per year. Traditionally the ore hauling had been done by the Swedish State Railways (SJ) and Norwegian State Railways (NSB). In the late 1980s, LKAB started a process to take over operations and increase efficiency by using heavier and longer trains. Because of the profitability in the operations, especially NSB was reluctant to lose the operations. In 1993, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiruna
(; se, Giron ; fi, Kiiruna ) is the northernmost Stad (Sweden), city in Sweden, situated in the province of Lapland, Sweden, Lapland. It had 17,002 inhabitants in 2016 and is the seat of Kiruna Municipality (population: 23,167 in 2016) in Norrbotten County. The city was originally built in the 1890s to serve the Kiruna Mine. The Esrange Space Center was established in Kiruna in the 1960s. Also in Kiruna are the Institute of Space Physics (Sweden), Institute of Space Physics and Luleå University of Technology's Department of Space Science. History Origins Archaeological findings have shown that the region around Kiruna has been inhabited for at least 6,000 years. Centuries before Kiruna was founded in 1900, the presence of iron ore at Kiirunavaara and Luossavaara had been known by the local Sami people, Sami population. In 1696, Samuel Mört, a bookkeeper of the Kengis works, wrote on rumours about the presence of iron in the two hills.Kummu 1997, p. 96. The ore became b ...

Rockfall
A rockfall or rock-fallWhittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984. . is a quantity/sheets of rock that has fallen freely from a cliff face. The term is also used for collapse of rock from roof or walls of mine or quarry workings. "A rockfall is a fragment of rock (a block) detached by sliding, toppling, or falling, that falls along a vertical or sub-vertical cliff, proceeds down slope by bouncing and flying along ballistic trajectories or by rolling on talus or debris slopes." Alternatively, a "rockfall is the natural downward motion of a detached block or series of blocks with a small volume involving free falling, bouncing, rolling, and sliding". The mode of failure differs from that of a rockslide. Causal mechanisms Favourable geology and climate are the principal causal mechanisms of rockfall, factors that include intact condition of the rock mass, discontinuities within the rockmass, weathering susceptibility, ground and surface water, ...

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

Single Track (rail)
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days, if the single track is not used for public passenger transit. Long freight trains are a problem if the passing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Luleå
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Main Line Through Upper Norrland
The Main Line Through Upper Norrland ( sv, Stambanan genom övre Norrland) is a long railway line between Bräcke, Jämtland County and Boden, Norrbotten County in Sweden. For military and regional policy reasons, it was built in very sparsely populated areas, far away from the more densely populated coast. The line has several branches to settlements on the coast, the ones to Umeå and Luleå being considered part of the line itself. Today the three largest settlements along the line are Boden (population 18,800), Älvsbyn (population 5,500) and Vännäs (population 4,100). In 2010, the Bothnia Line opened, which parallels the Main Line Through Upper Norrland along the coast from Sundsvall to Umeå. From 2013 all passenger traffic moved from the Main Line to the Bothnia Line, ending service between along the section between Bräcke and Vännäs. The North Bothnia Line is under planning, and will in a future allow high-speed trains to run to Luleå. Services The line is domi ...
