Società Italiana Ernesto Breda
Società Italiana Ernesto Breda (), more usually referred to simply as Breda, was an Italian mechanical manufacturing company founded by Ernesto Breda in Milan in 1886. History The firm was founded by Ernesto Breda in Milan in 1886. It originally manufactured locomotives and other railway machinery, but later branched out into armaments and aircraft. Occasionally, not continuously, the company also built trolleybuses. In 1935, it acquired the railway division of Officine Ferroviarie Meridionali and, soon afterwards, the aircraft division of the same company. Breda-designed machine guns such as the Breda Model 30 and Breda Model 37 were standard issue weapons for the Royal Italian Army during the Second Italo-Abyssinian War, the Italian Invasion of Albania and World War 2. At the peak of its wartime production, the company had 26,000 employees. By 1954, its workforce had been reduced to around 8,000. In 1962, Breda was nationalised as part of EFIM, but was liquidated in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tecnomasio
Tecnomasio was an Italian scientific and precision instrument company founded in the 1860s. By the beginning of the 20th century the company has begun to produce electrical equipment. After financial problems in the early 1900s the company was acquired by Brown Boveri becoming ''Tecnomasio Italiano Brown Boveri'' commonly known as TIBB; instrument production halted and the company became an industrial electrical equipment producer, one of the major companies in Italy. The company became part of the ABB group as ABB Tecnomasio in 1988 after the merger of its parent. The plant in Vado Ligure became part of Adtranz and later part of Bombardier's transportation group. History The origins of Tecnomasio go back as far as 1863 when mechanical and civil engineer Luigi Longoni, instrument maker Carlo Dell'Acqua, and optical scientist Ignazio Porro founded a company in Milan. Porro left the company in 1864 to be replaced by photographer Alessandro Duroni forming the company Duroni, Long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

The ALe 724 are a class of EMUs Emus may refer to: * Emu The emu () (''Dromaius novaehollandiae'') is the second-tallest living bird after its ratite relative the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the g ... of the Italian Ferrovie dello Stato, projected for suburban and regional services. History In 1978 the Ferrovie dello Stato received a series of prototype-EMUs, the so-called ″ Treni GAI″, that had for the first time a chopper technology instead of the classical electric equipment. As the tests of the ″treni GAI″ were positive, in May 1979 the FS ordered a series of EMUs derived from them. The lombard regional railway company FNM had already ordered in 1978 some similar railcars, numbered E.750. The FS ordered 60 trains, each made of 4 elements: 30 trains had two railcars and two trailers (ALe 724 + Le 884 + Le 883 + ALe 724) and due to their high acceleration were destined to the sub ...

Ferrovie Dello Stato
Ferrovie dello Stato Italiane S.p.A. ( "Italian Railways of the State"; previously only Ferrovie dello Stato, hence the abbreviation FS) is Italy's national state-owned railway holding company that manages transport, infrastructure, real estate services and other services in Italy and other European countries. History Early years The company was instituted by an act on 22 April 1905, taking control over the majority of the national railways, which up until that time were privately owned and managed. The president was nominated by the government. The first Director General was Riccardo Bianchi. In June 1912 Ferrovie dello Stato owned 5021 steam locomotives, 151 railcars, 10,037 coaches, 3371 baggage cars and 92,990 goods wagons.Victor Freiherr von Röll''Enzyklopädie des Eisenbahnwesens.''Band 6, Urban & Schwarzenberg, Berlin, 1914, p. 297.

FS Class ALe 582
The ALe 582 is an Italian electric multiple unit train designed for commuter and medium-distance services, developed in the mid-1980s to replace pre-war and immediately post-war EMUs and locomotive-hauled trains on various lines in Sicily and Southern Italy, although they later diffused on the whole FS network. They're part of the "ALe Elettroniche" (Chopper-controlled EMUs) or "G.A.I." (the name of the manufacturers' consortium) family, together with their predecessors ALe 724 and their successors, the ALe 642. While "ALe 582" is usually used to refer to the whole trainset, it officially indicates only the motor-cab car: the trailers are classified Le 562 (cab car), Le 763 (1st class) or Le 884 (2nd class). History The ALe 582 project was developed in the mid-eighties in order to replace old rolling stock used for commuter traffic and medium-distance (regional and local services) on secondary lines of Sicily and southern Italy.

FS Class ALe 642
FS ALe 642 is a class of Italian Electric Multiple Unit trains built from 1991 to 1995 for use on secondary lines and for commuter traffic. In service since 1991. Description This class is strictly derived from the previous ALe 582 and ALe 724 EMUs, sharing most of the mechanical and technical characteristics. The main differences are in the electrical part (especially traction control and low tension circuitry) and for the presence of 2nd class only seatings. The frontal part containing cabins consists of a preformed structure made of polyester reinforced with fiberglass. They originally had the ''Navetta'' livery, painted in gray with orange and red lateral stripes; now they all have received the corporate green-white XMPR livery. Technical description Units arrangement Like the previous EMUs on which they are based on, Class 642 can be divided in one or more sections containing a varying number of elements: * ALe 642.001 ÷ 60, the engine units with driving cabins (64 ...
