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. 105 bi-current sets, numbered 301-405, were built for the opening of the LGV Atlantique. 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". Modified unit 325 set the world speed record in 1990 on the new LGV before its o ...

Gare Montparnasse
Gare Montparnasse (; Montparnasse station), officially Paris-Montparnasse, one of the six large Paris railway termini, is located in the 14th and 15th arrondissements. The station opened in 1840, was rebuilt in 1852 and relocated in 1969 to a new station just south of the original location – where subsequently the prominent Montparnasse Tower was constructed. It is a central element to the Montparnasse area. The original station is noted for the Montparnasse derailment, where a steam train crashed through the station in 1895, an event captured in widely known photographs – and reproduced in full scale in several locations. The station serves intercity TGV trains to the west and southwest of France including Tours, Bordeaux, Rennes and Nantes, and suburban and regional services on the Transilien Paris – Montparnasse routes. There is also a metro station. Gare Montparnasse is the only mainline terminus in Paris not directly connected to the RER system, though the Mo ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of 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. 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 simu ...

Passenger Trains Running At Least At 300 Km/h In Commercial Operations
A passenger (also abbreviated as pax) is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward. The vehicles may be bicycles, buses, passenger trains, airliners, ships, ferryboats, and other methods of transportation. Crew members (if any), as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a passenger while on duty and the same with those working in the kitchen or restaurant on board a ship as well as cleaning staff, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being driven on company business. Railways In railway parlance, passenger, as well as being the end user of a service, is also a categorisation of the type of rolling stock used.Simmons, J ...

Electric Multiple Units With Locomotive-like Power Cars
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

TGV Trainsets
The TGV (french: Train à Grande Vitesse, "high-speed train"; previously french: TurboTrain à Grande Vitesse, label=none) is France's intercity high-speed rail service, operated by SNCF. SNCF worked on a high-speed rail network from 1966 to 1974 and presented the project to President Georges Pompidou who approved it. Originally designed as turbotrains to be powered by gas turbines, TGV prototypes evolved into electric trains with the 1973 oil crisis. In 1976 the SNCF ordered 87 high-speed trains from Alstom. Following the inaugural service between Paris and Lyon in 1981 on the LGV Sud-Est (LGV for ''Ligne à Grande Vitesse''; "high-speed line"), the network, centered on Paris, has expanded to connect major cities across France (including Marseille, Lille, Bordeaux, Strasbourg, Rennes and Montpellier) and in neighbouring countries on a combination of high-speed and conventional lines. The TGV network in France carries about 110 million passengers a year. The high-speed tracks, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Speed Record Rail Vehicles
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of the planet Earth that is not submerged by the ocean or other bodies of water. It makes up 29% of Earth's surface and includes the continents and various islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of the crust. Land plays important roles in Earth's climate system and is involved in the carbon cycle, nitrogen cycle, and water cycle. One-third of land is covered in trees, 15% is used for crops, and 10% is covered in permanent snow and glaciers. Land terrain varies greatly and consists of mountains, deserts, plains, plateaus, glaciers, and other landforms. In physical geology, the land is divided into two major categories: mountain ranges and relatively flat interiors called cratons. Both are formed over millions of years through plate tectonics. A major part of Earth's water cycle, streams shape the landscape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAIL (magazine)
''Rail'' is a British magazine on the subject of current rail transport in Great Britain. It is published every two weeks by Bauer Consumer Media and can be bought from the travel sections of UK newsstands. It is targeted primarily at the enthusiast market, but also covers issues relating to rail transport. ''Rail'' is more than four decades old, and was called ''Rail Enthusiast'' from its launch in 1981 until 1988. It is one of only two railway magazines that increased its circulation. It has roughly the same cover design for several years, with a capitalised italic red ''RAIL'' along the top of the front cover. Editorial policy ''Rail'' is customarily critical of railway institutions, including the Rail Delivery Group, the Office of Rail and Road, as well as, since it assumed greater railway powers, the Department for Transport. ''Rail's'' continuing campaigns include one against advertising and media images showing celebrities and others walking between the rails (an unsafe ...

AVE Class 100
The Renfe Class 100 is a high-speed train used for AVE services by the Renfe Operadora, in Spain. It was the first high-speed train put into service in Spain, in 1992. History This class lived through all the changes involved in the creation of the Spanish high-speed network; originally the plan was to build the high-speed route to Andalusia on an Iberian gauge track (). At the last minute, it was decided that it should be , meaning RENFE changed its original order for 24 Iberian gauge units to sixteen standard gauge ones, which were delivered between 1991 and 1993. After various changes in the contract with Alstom and compensation for delays the final eight were delivered; two standard gauge sets and 6 Iberian gauge sets. The Iberian sets became the Renfe Class 101 which used to operate the Euromed services along the Mediterranean corridor (this route is now covered by the RENFE Class 130 trains). Train 100.015 set one of the most important speed records in Spain, reachin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of High Speed Trains
The following is a list of high-speed trains that have been, are, or will be in commercial service. A high-speed train is generally defined as one which operates at or over in regular passenger service, with a high level of service, and often comprising multi-powered elements. In these tables, two or three maximum speeds are given: the column "Operated" refers to the maximum speed reached by the train in commercial operations, while the column "Design" refers to the theoretical maximum speed in commercial operations as announced by the manufacturer. Finally, a third "Record" speed may also be listed if there is an independently verified speed record. Trains with power cars and multiple units High-speed trains currently or soon in service High-speed trains no longer in service Experimental or modified Conventionally wheeled locomotive-hauled As trains can have multiple configurations on the same service, service name is used as an identifier.

LGV Est
The Ligne à Grande Vitesse Est européenne (East European High Speed Line), typically shortened to LGV Est, is a French high-speed rail line that connects Vaires-sur-Marne (near Paris) and Vendenheim (near Strasbourg). The line halved the travel time between Paris and Strasbourg and provides fast services between Paris and the principal cities of Eastern France as well as Luxembourg, Germany and Switzerland. The LGV Est is a segment of the Main Line for Europe project to connect Paris with Budapest with high-speed rail service. The line was built in two phases. Construction on the from Vaires-sur-Marne to Baudrecourt (near Metz and Nancy) began in 2004; the first phase entered into service in June 2007. Construction on the second phase from Baudrecourt to Vendenheim began in June 2010; the second phase opened to commercial service on 3 July 2016. Opening of the second phase was delayed after a train derailed near Eckwersheim during commissioning trials, resulting in 11 de ...

TGV POS
The TGV POS is a TGV train built by French manufacturer Alstom which is operated by the French national rail company, the SNCF, in France's high-speed rail lines. It was originally ordered by the SNCF for use on the new LGV Est, which was put into service in 2007. "POS" stands for ''Paris-Ostfrankreich-Süddeutschland'' (German for "Paris, Eastern France, Southern Germany"). History Each train is formed of eight existing TGV Réseau single-deck carriages paired with new power cars, with a total power output of and a top speed of under 25 kV. The TGV Réseau power cars thus freed have been matched to newer TGV Duplex carriages to create TGV Réseau Duplex sets. This is because traffic on the LGV Est is expected to be less than on the heavily congested LGV Sud-Est. Like the TGV TMST, the TGV POS power cars have asynchronous motors and, in case of failure, isolation of an individual motor in a powered bogie is possible. By using IGBT power packs, the new power cars are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
