Paris Métro Line 14
Paris Métro Line 14 (French: ''Ligne 14 du métro de Paris'') is one of the sixteen lines on the Paris Métro. It connects and Aéroport d'Orly (Paris Métro), Aéroport d'Orly on a north-west south-east diagonal via the three major stations of Gare Saint-Lazare, the Châtelet station, Châtelet–Les-Halles complex, and Gare de Lyon. The line goes through the centre of Paris, and also serves the communes of Saint-Denis, Seine-Saint-Denis, Saint-Denis, Saint-Ouen-sur-Seine, Clichy, Hauts-de-Seine, Clichy, Le Kremlin-Bicêtre, Gentilly, Val-de-Marne, Gentilly, Villejuif, Chevilly-Larue, L'Haÿ-les-Roses, Thiais and Paray-Vieille-Poste. The first Paris Métro line built from scratch since the 1930s, it has been operated completely automatically since its opening in 1998, and the very positive return of that experiment motivated the retrofitting of Paris Métro Line 1, Line 1 for full automation. Before the start of its commercial service Line 14 was known as project Météor, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RATP Group
The RATP Group () is a French state-owned enterprise (Établissement public à caractère industriel et commercial, EPIC) that operates public transport systems primarily in Paris, France.

Systra
SYSTRA is a multinational engineering and consulting group in the mobility sector, whose fields of activity include rail and public transport. SYSTRA employs about 10,300 people worldwide, and is a limited company which shareholders include French national railway company SNCF, RATP, and various banks. History French engineering The history of SYSTRA begins in 1957, when the SNCF created SOFRERAIL (French Company for Railway Design and Construction). Four years later, the RATP also creates its own engineering branch : SOFRETU (French Company for Public Transport Design and Construction). SOFRERAIL and SOFRETU merge in 1995, originally under the name SYSTRA-Sofretu-Sofrerail, later shortened to SYSTRA in 1997.

Alstom
Alstom SA () is a French multinational rolling stock manufacturer which operates worldwide in rail transport markets. It is active in the fields of passenger transportation, signaling, and locomotives, producing high-speed, suburban, regional and urban trains along with trams. The company and its name (originally spelled Alsthom) was formed by a merger between the electric engineering division of Société Alsacienne de Constructions Mécaniques (Als) and Compagnie Française Thomson-Houston (thom) in 1928. Significant acquisitions later included the Constructions Électriques de France (1932), shipbuilder Chantiers de l'Atlantique (1976), and parts of ACEC (late 1980s). A merger with parts of the British General Electric Company formed GEC Alsthom in 1989. Throughout the 1990s, the company expanded its holdings in the rail sector, acquiring German rolling stock manufacturer Linke-Hofmann-Busch and Italian rail signaling specialist Sasib Railways.

Paris Métro Line 1
Paris Métro Line 1 (French language, French: ''Ligne 1 du métro de Paris'') is one of the sixteen lines of the Paris Métro. It connects in the northwest and in the southeast. With a length of , it constitutes an important east–west transportation route within the City of Paris. Excluding Réseau Express Régional (RER) commuter lines, it is the busiest line on the network with 181.2 million travellers in 2017 or 496,000 people per day on average. The line was the network's first to open, with its inaugural section entering service in 1900. It is also the network's first line to be converted from manually driven operation to fully automated operation. Conversion, which commenced in 2007 and was completed in 2011, included new rolling stock (MP 05) and laying of platform edge doors in all stations. The first eight MP 05 trains (501 through 508) went into passenger service on 3 November 2011, allowing the accelerated transfer of the existing MP 89 CC stock to Paris Métro Lin ...

Guide Bar
Guide bars, or guiding bars are rubber-tyred metro systems that incorporate track. They have angle irons as outside of the two roll ways. The Busan Subway Line 4 lacks a rail track, and has I-beams installed as guide bars. The flanges are vertical. The Sapporo Municipal Subway, that lacks a rail track as well, has no guide bars. It has a central guide rail instead. Guide bars are also used to provide guidance for guided buses.

Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, 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 ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt
The volt (symbol: V) is the unit of electric potential, Voltage#Galvani potential vs. electrochemical potential, electric potential difference (voltage), and electromotive force in the International System of Units, International System of Units (SI). Definition One volt is defined as the electric potential between two points of a electrical conductor, conducting wire when an electric current of one ampere dissipates one watt of power (physics), power between those points. It can be expressed in terms of SI base units (metre, m, kilogram, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac = \text\text^2\text^. 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 (metre, m, kilogram, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac = \text\text^2\text^. It can also be expressed as amperes times ohms (curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
