FS Class E.464
The E.464 is a class of Italian railways electric locomotives. They were introduced in the course of the 1990s for hauling light trains, especially for commuter service. They were acquired by FS Trenitalia to replace the old E.424 and E.646, dating from the 1940s and 1950s. The class was originally designed by ABB Trazione, later ADTranz (was part of the Bombardier group, which was acquired by Alstom in 2021), and produced in the Italian plant of Vado Ligure. Cost per unit is 2.6 million Euro. With 717 locomotives currently in service (as of December 2015) the E.464 is the largest class in use by Trenitalia, and also the most numerous Italian locomotive class ever in service. History The E.464 derives from a project launched by the Italian Ferrovie dello Stato in the 1980s for a "modular" class of locomotives which would be easily adapted to commuter, inter-regional and cargo services. Initially, types with 4-axle (Bo-Bo, E.453/E.454) and 6-axle ( Bo-Bo-Bo, E.665/E.666) we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-phase
Three-phase electric power (abbreviated 3ϕ) is a common type of alternating current (AC) used in electricity generation, Electric power transmission, transmission, and Electric power distribution, 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 several people. In three-phase power, the voltage on each wire is 120 degrees phase shifted relative to each of the other wires. Because it is 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 electric power, single-phase circuit at the same line-to-ground voltage because it uses less conductor material to tr ...

Bo-Bo-Bo
A Bo-Bo-Bo or Bo′Bo′Bo′ (UIC classification) is a locomotive with three independent two-axle bogies with all axles powered by separate traction motors. In the AAR system, this is simplified to B-B-B due to the system only taking powered axles into consideration, not traction axles. The Bo-Bo-Bo configuration is often used to lower axle weight while keeping lateral forces low compared to a locomotive with two three-axle bogies, thus allowing the locomotive to use lightly laid track, in particular narrow-gauge railways. Bo-Bo-Bo locomotives The arrangement is extensively used on Italian and Japanese railways. Other examples include New Zealand's DJ, EW and EF classes; the Eurotunnel Class 9 locomotives, which were themselves derived from the New Zealand EF class; the Swiss SBB Re 6/6 (Re 620); the Russia Railways VL65, EP1 (EP1M), EP10 and EP20; and the South Korean Korail Class 8000. China imported 6K electric locomotive from Japan between 1986 and 1987. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paderno D'Adda
Paderno d'Adda ( Brianzöö: ; Bergamasque: ) is a town and ''comune'' in the province of Lecco, in Lombardy. It is well known in the rest of Italy for the cast-iron San Michele Bridge built in the late nineteenth century following the Tour Eiffel style. It is said that Leonardo da Vinci used the Paderno's scenery as base for his famous painting Virgin of the Rocks The ''Virgin of the Rocks'' (), sometimes the ''Madonna of the Rocks'', is the name of two paintings by the Italian Renaissance artist Leonardo da Vinci, of the same subject, with a composition which is identical except for several significant de ....

Emilia-Romagna
Emilia-Romagna (, , both , ; or ; ) is an Regions of Italy, administrative region of northern Italy, comprising the historical regions of Emilia (region), Emilia and Romagna. Its capital is Bologna. It has an area of , and a population of 4.4 million. Emilia-Romagna is one of the wealthiest and most developed regions in Europe, with the third highest gross domestic product per capita in Italy. It is also a cultural center, being the home of the University of Bologna, the oldest university in the world. Some of its cities, such as Modena, Parma, Ferrara, and Ravenna, are UNESCO heritage sites. It is a center for food and automobile production (such as Ferrari, Lamborghini, and Maserati). It has coastal resorts such as Cervia, Cesenatico, and Rimini. In 2018, the Lonely Planet guide named Emilia-Romagna as the best place to see in Europe. Etymology The name ''Emilia-Romagna'' is a legacy of Ancient Rome. ''Emilia'' derives from the ''via Aemilia'', the Roman road connecting Pia ...

Lombardy
The Lombardy Region (; ) is an administrative regions of Italy, region of Italy that covers ; it is located in northern Italy and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Lombardy is located between the Alps mountain range and tributaries of the river Po (river), Po, and includes Milan, its capital, the largest metropolitan area in the country, and among the largest in the EU. Its territory is divided into 1,502 ''comuni'' (the region with the largest number of ''comuni'' in the entire national territory), distributed among twelve administrative subdivisions (eleven Provinces of Italy, provinces plus the Metropolitan City of Milan). The region ranks first in Italy in terms of population, population density, and number of local authorities, while it is fourth in terms of surface area, after Sicily, Piedmont, and Sardinia. It is the second-most populous Region (Europe), region of the European Union (EU), and the List of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gate Turn-off Thyristor
A gate turn-off thyristor (GTO) is a type of high-power (e.g. 1200 V AC) thyristor that unlike a normal thyristor is fully controllable and can be turned On and Off by their gate lead. It was invented by General Electric. Device description Normal thyristors ( silicon-controlled rectifiers) are not fully controllable switches (a fully controllable switch can be turned on and off at will). Thyristors can only be turned on using the gate lead, but cannot be turned off using the gate lead. Thyristors are switched on by a gate signal, but even after the gate signal is de-asserted (removed, reverse biased), the thyristor remains in the on state until a turn-off condition occurs (which can be the application of a reverse voltage to the terminals or a decrease of the forward current below a certain threshold value known as the ''holding current''). Thus, a thyristor behaves like a normal semiconductor diode after it is turned on, or ''fired''. The GTO can be turned on by a ...

Scharfenberg Coupler
The Scharfenberg coupler (, abbreviated ''Schaku'') is a commonly used type of fully automatic railway coupling. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit systems. The ''Schaku'' is superior in many ways to the Janney coupler, AAR (Janney/knuckle) coupler because it also automates electrical and pneumatic connections and disconnections. However, there is no standard for the placement of these electro-pneumatic connections. Some rail operators have placed them on the sides while others have placed them either below or above the mechanical portion of the coupler. Scharfenberg as a technical design principle and brand name Scharfenberg and the abbreviation Schaku are registered trademarks of Voith Patent GmbH. For this reason, only couplings from Voith can use this name. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
