A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as:

A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations.

Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups. Read more...

Steorn Ltd (/ˈstjɔːrn/) was a small, private technology development company based in Dublin, Ireland. In August 2006, it announced that it had developed a technology to provide "free, clean, and constant energy" via an apparent perpetual motion machine, something which is contrary to the law of conservation of energy, a fundamental principle of physics.

Steorn challenged the scientific community to investigate their claim and, in December 2006, said that it had chosen a jury of scientists to do so. In June 2009 the jury gave its unanimous verdict that Steorn had not demonstrated the production of energy. Read more...

Aktiengesellschaft (German pronunciation: [ˈaktsi̯ənɡəˌzɛlʃaft]; abbreviated AG, pronounced [aːˈgeː]) is a German word for a corporation limited by share ownership (i.e. one which is owned by its shareholders) whose shares may be traded on a stock market. The term is used in Germany, Austria, Switzerland (where it is equivalent to a société anonyme or a società per azioni), and South Tyrol for companies incorporated there. It is also used in Luxembourg (as Aktiëgesellschaft), although the equivalent French language term société anonyme is more common. In the United Kingdom, the equivalent term is "PLC" and in the United States while the terms "incorporated" or "corporation" are typically used, technically the more precise equivalent term is "joint-stock company" (though note for the British term only a minority of public limited companies have their shares listed on stock exchanges).

IORE Kiruna.jpg

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 8,600 tonnes (8,500 long tons; 9,500 short tons), 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, LKAB received permission to operate their own trains in Sweden, and from 1996 in Norway. MTAB and MTAS were created in 1996 when they took over the hauling formerly operated by NSB and SJ. It inherited Dm3 and El 15 locomotives. Originally established as a joint venture between LKAB, NSB and SJ, with the mining company as a majority owner, LKAB bought the whole company in 1999. By 2011, the renewal process will be finished, and only trains pulled by Iore will be in operation. Read more...
