ŽS Series 444
The ŽS series 444 is an electric locomotive built for Serbian Railways formed by the overhaul and modernization of 30 ŽS series 441 locomotives. History This series is originally based on the license of the Swedish company ASEA and the SJ Rb locomotive from Sweden. The 30 electric locomotives originally from series 441 of Serbian Railways have been modified by Končar Group from Zagreb, Croatia and MIN (Mašinska Industrija Niš) from Niš, Serbia. First modified locomotive, that received new code number - ŽS series 444 (former 441-077), has become operational in summer 2004. Last modified locomotive was opened to traffic in January 2007. The modification is based on the restoration of 441 series. Voltage This locomotive utilises 25 kV/50 Hz AC. Liveries All class 444 locomotives of Serbian Railways have red and greyish-blue livery which is the same as for other electric locomotives operated - 441 and 461 series.

ASEA
''Allmänna Svenska Elektriska Aktiebolaget'' (English translation: General Swedish Electrical Limited Company; Swedish abbreviation: ASEA) was a Swedish industrial company. History ASEA was founded in 1883 by Ludvig Fredholm in Västerås as a manufacturer of electrical light and generators. After merging with Wenström's & Granström's Electrical Power Company (''Wenströms & Granströms Elektriska Kraftbolag'') the name was changed to ''Allmänna Svenska Elektriska Aktiebolaget'', literally the "General Swedish Electrical Limited Company", or a ''ASEA'' for short. In 1987, it announced a merger with the Swiss company Brown, Boveri & Cie (BBC) to form ABB Group. ABB Group began operations in 1988. After this merger, ABB Group acquired several companies, including the power transmission and distribution operations of the Westinghouse Electric Corporation and the Combustion Engineering Group. *1889 - the partner Jonas Wenström creates 3-phased generators, motors and transfor ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Railway Locomotives Introduced In 2004
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 Road transport or road transportation is a type of transport using roads. Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations e ..., 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 Railroad tie, sleepers (ties) set in track ballast, 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 generall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
