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 ...

TREVI
The area of freedom, security and justice (AFSJ) is a collection of justice as well as migration & home affairs policies designed to ensure security, rights and free movement within the European Union (EU). Fields covered include the harmonisation of private international law, extradition arrangements between member states, policies on internal and external border controls, common travel visa, immigration and asylum policies and police and judicial cooperation. As internal borders have been removed within the EU, cross-border police cooperation has had to increase to counter cross-border crime. Some notable projects related to the area are the European Arrest Warrant, the Schengen Area and Frontex patrols. Overview Over the years, the EU has developed a wide competence in the area of home affairs & migration, fundamental rights and justice. Home affairs & migration For example, the EU operates facilities such as the Schengen Information System, the Visa Information System, th ...

Bo′Bo′
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FS Trenitalia
Trenitalia is the primary train operator in Italy. A subsidiary of Ferrovie dello Stato Italiane, itself owned by the Italian government, the company was established in 2000 following a European Union directive on the deregulation of rail transport. History The Italian government formed Trenitalia to comply with Regulation (European Union), European regulations. The European Commission's First Railway Directive from 1991 (91/440/EC) required separation of accounting between entities which manage the rail infrastructure and entities which provide the actual rail transportation. On 1 June 2000, therefore, Italy created Trenitalia as the primary rail transportation company and on 1 July 2001 established Rete Ferroviaria Italiana (RFI) as the company overseeing the rail network. However, the separation was only formal, since both are subsidiaries of the Ferrovie dello Stato Italiane holding and are owned wholly by the government. Trenitalia operated freight rail services under the Tr ... [...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 ...

ETR 500
ETR 500 ('' Elettro Treno Rapido 500'') is a family of Italian high-speed trains built by AnsaldoBreda and introduced in 1993. Designed under the aegis of the Ferrovie dello Stato (FS), it is now operated by Trenitalia on RFI tracks. History The opening of the Direttissima line, connecting Florence with Rome, in stages between 1978 and 1991 was the first high speed line in Europe. Then, in the 1990s, FS unveiled plans to build a whole new high speed network. As the larger part of the network would be suited for speeds of , new, non-tilting trains had to be designed as the tilting equipment used in the ETR 450, 460 and 480 Pendolino series was not suited for speeds of over . The new train was to be built by the TREVI (''TREno Veloce Italiano'', "Italian Fast Train") consortium, formed by Breda Costuzioni Ferroviarie, FIAT Ferroviaria, Tecnomasio and Firema Trasporti. Prototypes In 1988 the first prototype motorcar, called ETR 500-X and nicknamed "Remo," as the brother of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
