MRV (Paris Métro)
MRV, project name, for Matériel Roulant Voyageurs (Passenger Rolling Stock) are the future rolling stock for the new Paris Métro Line 18, Line 18 of the Paris Métro. Background As part of the construction of Line 18 of the Paris metro, the Société du Grand Paris launched a call for tenders in the first quarter of 2019 for the acquisition of new self-driving trains and associated systems. In October 2021, the Société du Grand Paris announced that the manufacturer Alstom had been selected to supply 37 trains from the Alstom Metropolis range with three cars, automation systems and centralized operating command stations for a total amount of 400 million euros. A first firm tranche of 15 trains for an amount of 230 million euros has been ordered for delivery from 2024 and commercial entry into service of the new trains should take place when Line 18 opens on its section from Massy - Palaiseau to CEA Saint-Aubin, scheduled for 2026. The trains will be designed at the Alstom s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. In 1998, GEC Alsthom was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valenciennes
Valenciennes (, also , , ; ; or ; ) is a communes of France, commune in the Nord (French department), Nord Departments of France, department, Hauts-de-France, France. It lies on the Scheldt () river. Although the city and region experienced a steady population decline between 1975 and 1990, it has since rebounded. History Early history In 923, it passed to the Duchy of Lower Lotharingia dependent on the Holy Roman Empire. Once the Empire of the Franks was established, the city began to develop, though the archaeological record has still not revealed all it has to reveal about this period. In 1259, Valenciennes was the site of a General Chapter of the Dominican Order at which Thomas Aquinas together with masters Bonushomo Britto, Florentius, Albert the Great, Albert, and Pope Innocent V, Peter took part in establishing a ''ratio studiorum'' or program of studies for the Dominican Order that featured the study of philosophy as an innovation for those not sufficiently trained ...

Alstom Metropolis
The Alstom Metropolis is a family of electric multiple units designed and produced by the French rolling stock manufacturer Alstom. It is designed for high capacity rapid transit or metro rail infrastructure systems. Trains can be run in various configurations, the length alone varying between two and ten cars; it is also suitable for both manned or unmanned operations. More than 4,000 Metropolis cars have been manufactured, the type is reportedly in service with 50 operators distributed around the world. Cities operating the Metropolis include Singapore, Shanghai, Budapest, Warsaw, Nanjing, Montreal, Buenos Aires, São Paulo, Lima, Santiago, Barcelona, Guadalajara, Istanbul, Santo Domingo, Chennai, Kochi, Dubai, Lucknow, Sydney, Amsterdam, Xiamen, Hanoi, and Riyadh. Design features Alstom's Metropolis family of electric multiple units is highly adaptable; the basic body can significantly vary in size between small, medium and wide configurations to meet a variety of client's ...

Contact Shoe
A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and Electric multiple unit, EMUs to carry electric power (Electric current, current) from overhead lines, electric third rails, or ground-level power supply, ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrical conductivity, electrically conductive but mounted Electrical insulation, insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or Electric motor, motor. The Rail profile, stee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrodynamic Brake
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical ci ...

Regenerative Brake
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effectively turning the traction motor into a generator. Feeding power backwards through the system like this allows the energy harvested from deceleration to resupply an energy storage solution such as a battery or a capacitor. Once stored, this power can then be later used to aid forward propulsion. Because of the electrified vehicle architecture required for such a braking system, automotive regenerative brakes are most commonly found on hybrid and electric vehicles. This method contrasts with conventional braking systems, where excess kinetic energy is converted to unwanted and wasted heat due to friction ...
