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 ''ASEA'' for short. In 1987, it announced a merger with the Swiss company Brown, Boveri & Cie (BBC) to form ABB. The merge took effect on 1 January 1988.ASEA-BBC merger ''Modern Railways'' issue 472 January 1988 page 34 After this merger, ABB acquired several companies, including the power transmission and distribution operations of the Westinghouse Electric Corporation and the Combustion Engineering Group. *1889 – the partner J ...

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 (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), 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 loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 2004
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th ...

Electric Locomotives Of Serbia
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

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. Humans, and many other animals, have 5 digits on their limbs. Mathematics 5 is a Fermat prime, a Mersenne prime exponent, as well as a Fibonacci number. 5 is the first congruent number, as well as the length of the hypotenuse of the smallest integer-sided right triangle, making part of the smallest Pythagorean triple ( 3, 4, 5). 5 is the first safe prime and the first good prime. 11 forms the first pair of sexy primes with 5. 5 is the second Fermat prime, of a total of five known Fermat primes. 5 is also the first of three known Wilson primes (5, 13, 563). Geometry A shape with five sides is called a pentagon. The pentagon is the first regular polygon that does not tile the plane with copies of itself. It is the largest face any of the five regular three-dimensional regular Platonic solid can have. A conic is determine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SJ Rb
Rb is an electric locomotive operated by Swedish State Railways (). Six locomotives were built by Allmänna Svenska Elektriska Aktiebolaget, ASEA, in three series designated Rb1, Rb2 or Rb3. History During the 1950s SJ saw the need for a new universal locomotive, since the SJ D, D-series was aging. In 1955 the SJ Ra, 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 1963 for the Brasov-Predeal mainline (at the time it was electrified since 9 June 1963 and 3 more manufacturers tested their locomotives there), and later in Yugoslavia in 1967, and based on this exports were made to the Yugoslav Railways (JŽ class 441 and JŽ series 461, 461), Căile Ferate Române of Romania (CFR Class EA and EC) and for Norwegian Railways (NSB El 15 ...
