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, 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 facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Locomotives Of Serbia
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a un ...

25 KV AC Locomotives
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Bo′Bo′ Locomotives
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives. Bo-Bo Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units. Most early electric locomotives shared commonalities with the steam engines of their time. These features included side rods and frame mounted driving axles with leading and trailing axles. The long rigid wheelbase and the leading and trailing axles reduced cornering stability and increased weight. The Bo-Bo con ...

SJ Rb
Rb is an electric locomotive operated by Swedish State Railways ( sv, Statens Järnvägar, SJ). Six locomotives were built by ASEA, in three series designated Rb1, Rb2 or Rb3. History During the 1950s SJ saw the need for a new universal locomotive, since the D-series was aging. In 1955 the Ra-series had proved successful with bogie wheels. At the same time there was interest to make a locomotive that could be exported abroad. The result was an agreement between ASEA and SJ where six test engines were delivered. The testing of the Rb was successful, so it was sent to Romania for trials in 1965 for the Brasov- Predeal mainline (at the time it was electrified since 9 June 1963 and 3 more manufacturers tested their locomotives there the previous years), and later in Yugoslavia in 1967, and based on this exports were made to the Yugoslav Railways ( JŽ class 441 and 461), Căile Ferate Române of Romania ( CFR Class EA and EC) and for Norwegian Railways ( NSB El 15, derived from th ...
