FS Class E.330
The FS Class E.330 was a small class of three-phase electric locomotive used in Italy, introduced in the 1910s. History In the late 1900s, the success of the three-phase electrification on mountain lines such as the Valtellina line, the Simplon Tunnel and the Giovi Pass line, led the newly formed Ferrovie dello Stato, under the direction of Riccardo Bianchi, to extend the electrification to other lines, where electric locomotives gave better performance. For the new lines to be electrified, three batches of electric locomotives were ordered, including the E.330 and the E.550 (a type E.551 was ordered but not built). Unlike the previous electric locomotives used on mountain lines, the new locomotives had to be able to vary their speed, a capability which at the time was difficult to achieve, due to the fact that the three-phase motor spins at constant speed set by the feeding current frequency. The E.330 was designed to have four speeds (where the E.430 had only one and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Three-phase AC Locomotives
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large induction mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 1914
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 faciliti ...

1′C1′ Locomotives
Rigid-framed electric locomotives were some of the first generations of electric locomotive design. When these began the traction motors of these early locomotives, particularly with AC motors, were too large and heavy to be mounted directly to the axles and so were carried on the frame. One of the initial simplest wheel arrangements for a mainline electric locomotive, from around 1900, was the 1′C1′ arrangement, in UIC classification. Some of these locomotives had their driving wheels coupled with coupling rods, as for steam locomotives. Others had individual motors for each axle, as would later become universal. By the middle of the century, the bogie arrangement for locomotives became more popular and rigid-framed locomotives are now rare, except for small shunters. 1′C1′ 1′C1′ is the UIC classification for a railway locomotive with a wheel arrangement of three coupled driving wheels, with a leading and trailing articulated pony truck. The driving wheels are coup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lombardy
Lombardy ( it, Lombardia, Lombard language, Lombard: ''Lombardia'' or ''Lumbardia' '') is an administrative regions of Italy, region of Italy that covers ; it is located in the northern-central part of the country and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Over a fifth of the Italian gross domestic product (GDP) is produced in the region. The Lombardy region is located between the Alps mountain range and tributaries of the Po river, and includes Milan, the largest metropolitan area in the country, and among the largest in the European Union (EU). Of the fifty-eight UNESCO World Heritage Sites in Italy, eleven are in Lombardy. Virgil, Pliny the Elder, Ambrose, Gerolamo Cardano, Caravaggio, Claudio Monteverdi, Antonio Stradivari, Cesare Beccaria, Alessandro Volta and Alessandro Manzoni; and popes Pope John XXIII, John XXIII and Pope Paul VI, Paul VI originated in the area of modern-day Lombardy region.

Liguria
Liguria (; lij, Ligûria ; french: Ligurie) is a Regions of Italy, region of north-western Italy; its Capital city, capital is Genoa. Its territory is crossed by the Alps and the Apennine Mountains, Apennines Mountain chain, mountain range and is roughly coextensive with the former territory of the Republic of Genoa. Liguria is bordered by France (Provence-Alpes-Côte d'Azur) to the west, Piedmont to the north, and Emilia-Romagna and Tuscany to the east. It rests on the Ligurian Sea, and has a population of 1,557,533. The region is part of the Alps–Mediterranean Euroregion. Etymology The name ''Liguria'' predates Latin and is of obscure origin. The Latin adjectives (as in ) and ''Liguscus'' reveal the original root of the name, ''ligusc-'': in the Latin name -sc- was shortened to -s-, and later turned into the -r- of , according to rhotacism (sound change), rhotacism.

FS Class 685
The Ferrovie dello Stato (FS; Italian State Railways) Class 685 ( it, Gruppo 685) is a class of 2-6-2 'Prairie' express train steam locomotives. These are colloquially known as ''Regine'' ('Queens' in Italian), mirroring their fame as one of the most successful and appreciated Italian steam locomotives. Design and construction The Class 685 was the simple-expansion and superheated version of the pre-existing FS Class 680 locomotive, the premier express locomotive in Italy up to that date; while discarding the complicated compound feature, the 685 nonetheless kept the unusual feature of having the cylinders arranged in pairs, with each pair being served by a single piston valve with crossed ports (a feature typical of the Plancher engine of the Class 680 and other Italian locomotives). The first 106 locomotives were built up to World War I, and had right-hand drive; construction resumed in 1920, and the remaining 165 were all built, up to 1928, with left-hand drive and a slightly ...

Utility Frequency
The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains electricity by country. During the development of commercial electric power systems in the late-19th and early-20th centuries, many different frequencies (and voltages) had been used. Large investment in equipment at one frequency made standardization a slow process. However, as of the turn of the 21st century, places that now use the 50 Hz frequency tend to use 220–240 V, and those that now use 60 Hz tend to use 100–127 V. Both frequencies coexist today (Japan uses both) with no great technical reason to prefer one over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
