Project V150
Operation V150, where 150 refers to a target speed in metres per second, was a series of high-speed trials carried out on the LGV Est. The V150 was a specially configured TGV high-speed train (weighing only ) notable for breaking the world railway speed record on 3 April 2007. The train was built in France and reached a speed of on an unopened section of the LGV Est between Strasbourg and Paris, in France topping the previous record of set in 1990. Record of 2007 Operation V150 trials were carried out on the LGV Est prior to its June 2007 opening. The trials were conducted jointly by SNCF, TGV builder Alstom, and LGV Est owner Réseau Ferré de France between 15 January 2007 and 15 April 2007. Following a series of increasingly high-speed runs, the official speed record attempt took place on 3 April 2007. The top speed of , ) was reached at kilometre point 193 near the village of Le Chemin, between the Meuse and Champagne-Ardenne TGV stations, where the most favorable p ...

TGV World Speed Record 574 Km Per Hour
The TGV (; , , 'high-speed train') is France's intercity high-speed rail service. With commercial operating speeds of up to on the newer lines, the TGV was conceived at the same period as other technological projects such as the Ariane 1 rocket and Concorde supersonic airliner; sponsored by the Government of France, those funding programmes were known as (' national champion') policies. In 2023 the TGV network in France carried 122 million passengers. The state-owned SNCF started working on a high-speed rail network in 1966. It presented the project to President Georges Pompidou in 1974 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, the network, centred on Paris, has expanded to connect major cities across France, including Marseill ...

Land Speed Record Rail Vehicles
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of Earth not submerged by the ocean or another body of water. It makes up 29.2% of Earth's surface and includes all continents and 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 an important role in Earth's climate system, being involved in the carbon cycle, nitrogen cycle, and water cycle. One-third of land is covered in trees, another third is used for agriculture, and one-tenth is covered in permanent snow and glaciers. The remainder consists of desert, savannah, and prairie. Land terrain varies greatly, consisting 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 form over millions of years through plate tectonics. Streams – a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LGV Construction
High-speed railway track construction is the process by which (LGV, litt. "''high-speed railway line''"), the land on which TGV trains are to run, is prepared for their use, involving carving the track bed and laying the track. This construction technique is used both for the French TGV network and other TGV-based networks outside of France. It is similar to the building of standard railway lines, but there are differences. In particular, construction process is more precise in order for the track to be suitable for regular use at 300 km/h (186 mph). The quality of construction was put to the test in particular during the TGV world speed record runs on the LGV Atlantique; the track was used at over 500 km/h (310 mph) without suffering significant damage. This contrasts with previous French world rail speed record (326/331 km/h in 1955) attempts which resulted in severe deformation of the track.

Land Speed Record For Railed Vehicles
This article provides an overview of speed records in rail transport. It is divided into absolute records for rail vehicles and fastest connections in the timetable. Current speed records The world record for a conventional wheeled passenger train is held by a modified French TGV high-speed (with standard equipment) code named V150, set in 2007 when it reached on a section of LGV Est line, part of the Trans-European high-speed rail network. Japan's experimental maglev train L0 Series achieved on a magnetic levitation track in 2015. Under commercial traffic and practical conditions where trains carry passengers across from one station to another, the world records for top operating speeds of maglev and single-phase trains are held respectively by China's Shanghai Maglev Train with a top speed of and CR400 Fuxing Hao at . They are followed by France's TGV Duplex, Japan's E5 Series Shinkansen and the German ICE 3 (when operating in France) which all have maximum o ...

Live Television
Live television is a television production broadcast in real-time, as events happen, in the present. In a secondary meaning, it may refer to streaming television where all viewers watch the same stream simultaneously, rather than watching video on demand. Shows broadcast live include newscasts, morning shows, awards shows, sports programs, reality programs and, occasionally, episodes of scripted television series. Live television was more common until the late 1950s, when videotape technology was invented. Because of the prohibitive cost, adoption was slow, and some scripted television shows remained live until the 1970s, such as soap operas. To prevent unforeseen issues, live television programs may be delayed, which allows censors to edit the program. Some programs may be broadcast live in certain time zones and delayed in others. Types of programs From the early days of television until about 1958, live television was used heavily, except for filmed programs such as ...

Aérospatiale Corvette
The Aérospatiale SN 601 Corvette is a French business jet of the early 1970s developed and manufactured by aerospace manufacturer Aérospatiale. Sales of the type were disappointing, leading to only 40 Corvettes being constructed, including the prototypes, prior to production being terminated. In response to an open request by the French government for a compact twin-turbofan engine-equipped liaison/ trainer aircraft, aircraft manufacturers Sud Aviation and Nord Aviation decided to embark upon development of a new business jet that could also fulfil the government demand as well. The joint venture's design, initially designated as the ''SN 600 Diplomate'', was first publicly displayed at the 1968 Hanover ILA Air Show. On 16 July 1970, the prototype SN 600 performed the type's maiden flight; on 23 March 1971, this prototype was lost during a test flight. A pair of improved ''SN 601'' prototypes were then constructed; on 20 December 1972, the first of these prototypes conducted i ...

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 LGV Est, which was put into service in 2007. POS is an abbreviation of ''Paris-Ostfrankreich-Süddeutschland'' (), the route of the LGV Est. History The TGV POS project was a unique extension of the TGV Duplex order. Alstom delivered to SNCF 38 new tri-current power cars and 19 sets of double-deck Duplex passenger carriages. The tri-current power cars were paired with the 19 sets of single-level passenger carriages from TGV Réseau trainsets, while the two-level Duplex passenger carriages were paired with the 38 dual-current power cars from the Réseau trainsets. The tri-current function was necessary for the LGV Est, which ends at the German border, where the electrification switches to the system. Meanwhile, the heavily congested lines where the Réseau train ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Ballast
Track ballast is the material which forms the trackbed upon which railroad ties (UK: sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the compression load of the railroad ties, rails, and rolling stock; to facilitate drainage; and keep down vegetation that can compromise the integrity of the combined track structure. Ballast also physically holds the track in place as the trains roll over it. Not all types of railway tracks use ballast. A variety of materials have been used as track ballast, including crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay. The term "ballast" comes from a nautical term for the stones used to stabilize a ship. Construction The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast ...

Transverse Wave
In physics, a transverse wave is a wave that oscillates perpendicularly to the direction of the wave's advance. In contrast, a longitudinal wave travels in the direction of its oscillations. All waves move energy from place to place without transporting the matter in the transmission medium if there is one. Electromagnetic waves are transverse without requiring a medium. The designation “transverse” indicates the direction of the wave is perpendicular to the displacement of the particles of the medium through which it passes, or in the case of EM waves, the oscillation is perpendicular to the direction of the wave. A simple example is given by the waves that can be created on a horizontal length of string by anchoring one end and moving the other end up and down. Another example is the waves that are created on the membrane of a drum. The waves propagate in directions that are parallel to the membrane plane, but each point in the membrane itself gets displaced up and dow ...

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 ...
