TGV World Speed Record
The TGV (''train à grande vitesse'', 'high-speed train') holds a series of Land speed record for railed vehicles, land speed records for rail vehicles achieved by SNCF, the French national railroad, railway, and its industrial partners. The high-speed trials are intended to expand the limits of high-speed rail technology, increasing speed and comfort without compromising safety. The current world speed record for a commercial train on steel wheels is held by the French TGV at 574.8 km/h (357.2 mph), achieved on 3 April 2007 on the new LGV Est. TGV 001 The TGV 001 was an experimental gas turbine-electric locomotive-powered trainset built by Alstom to break speed records between 250–300 kilometres per hour. It was the first TGV prototype and was commissioned in 1969, to begin testing in 1972. It achieved a top speed of on 8 December 1972.

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Vendôme TGV Station
Vendôme (, ) is a Subprefectures in France, subprefecture of the Departments of France, department of Loir-et-Cher, France. It is also the department's third-biggest Communes of France, commune with 15,856 inhabitants (2019). It is one of the main towns along the river Loir. The river divides itself at the entrance of Vendôme, intersecting it into numerous different arms. The town has a rich Middle Ages, medieval history and many historical monuments. History Vendôme (in ) appears originally to have been a Gaul, Gallic , replaced later by a feudal castle, around which the modern town arose. Christianity was introduced by in the 5th century, and the important abbey of the Trinity (which claimed to possess a tear shed by Jesus at the tomb of Lazarus of Bethany, Lazarus) was founded about 1030. When the reign of the House of Capet began, Vendôme formed the chief town of a county belonging to Bouchard, called "the Venerable", who died in the monastery of in 1007. The succ ...

Radius
In classical geometry, a radius (: radii or radiuses) of a circle or sphere is any of the line segments from its Centre (geometry), center to its perimeter, and in more modern usage, it is also their length. The radius of a regular polygon is the line segment or distance from its center to any of its Vertex (geometry), vertices. The name comes from the Latin ''radius'', meaning ray but also the spoke of a chariot wheel.Definition of Radius at dictionary.reference.com. Accessed on 2009-08-08. The typical abbreviation and mathematical symbol for radius is ''R'' or ''r''. By extension, the diameter ''D'' is defined as twice the radius:Definition of radius at mathwords.com. ...

SNCF TGV Atlantique
The TGV Atlantique (TGV-A) is a class of high-speed trains used in France by SNCF; they were built by Alstom between 1988 and 1992, and were the second generation of TGV trains, following on from the TGV Sud-Est trainsets. The trains were named after the Ligne à Grande Vitesse Atlantique () that they were originally built for. 105 bi-current sets, numbered 301-405 were built. Entry into service began in 1989. They are long and wide. They weigh , and are made up of two power cars and ten carriages with a total of 485 seats. They were built for a maximum speed of with total power under 25 kV. From 2015 onwards, many of these units have been scrapped with only 28 still in service in 2022. Most of the remaining fleet have been refurbished and mainly see service on slower trains between Paris and Bordeaux that use only a portion of the LGV Atlantique and LGV Sud Europe Atlantique. Fast through services on the route are now operated by the higher capacity TGV "Océane". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Brake
A brake is a machine, mechanical device that inhibits motion by absorbing energy from a moving system. It is used for Acceleration, slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as Compressed air energy storage, pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the en ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...

Traction (engineering)
Traction, traction force or tractive force is a force used to generate Motion (physics), motion between a body and a tangential surface, through the use of either dry friction or shear force. It has important applications in vehicles, as in ''tractive effort''. ''Traction'' can also refer to the ''maximum'' tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the ''coefficient of traction'' (similar to coefficient of friction). It is the force which makes an object move over the surface by overcoming all the resisting forces like friction, normal loads (load acting on the tiers in negative ''Z'' axis), air resistance, rolling resistance, etc. Definitions Traction can be defined as: In vehicle dynamics, tractive force is closely related to the terms tractive effort and drawbar pull, though all three terms have different definit ...

Aerodynamics
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

Railroad Switch
A railroad switch (American English, AE), turnout, or (set of) points (Commonwealth English, CE) is a mechanical installation enabling railway trains to be guided from one Rail tracks, track to another, such as at a Junction (rail), railway junction or where a Branch line, spur or Siding (rail), siding branches off. Design The parts of a turnout are known by different names in different jurisdictions. The main terms in U.S. and UK usage are shown in the selectable diagrams. In this article, the U.S. term is listed first and UK second, in parentheses. The most common type of switch consists of a pair of linked tapering rails, known as ''points'' (''switch rails'' or ''point blades''), lying between the diverging outer rails (the ''stock rails''). These points can be moved laterally into one of two positions to direct a train coming from the point blades toward the straight path or the diverging path. A train moving from the narrow end toward the point blades (i.e. it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
