TGV 001
The TGV 001 (''Train à Grande Vitesse 001'') was an experimental gas turbine-powered TGV prototype built by Alstom in France. Commissioned in 1969, began testing in 1972 and reached speeds between . It was part of a vast research program on high rail speeds which covered all technical aspects, principally traction, the behaviour of the vehicles, braking, aerodynamics and signalling. Originally, two trains were to be built, but only one was produced. The second was to be a tilting train equipped with an active tilting system, but was abandoned owing to technical difficulties. Description This turbotrain was built in a radically different fashion than its predecessors (the ETG and the RTG); it was composed of two power cars and three carriages, all with driving axles. This concept as well as the shape of the TGV 001 was kept when designing the future TGV. Each axle was equipped with a traction motor with the advantage of small weight per axle but maximum power.

TGV 001 Bordeaux-Saint-Jean
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 champions, 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 gas turbine train, 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 cit ...

Centre Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the cas ... [...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 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] |
Turbotrain
The Turbotrain was any of several French high-speed, gas turbine trains. The earliest Turbotrain entered service in 1967, for use on France's SNCF intercity lines. There were four versions in total, with the last exiting service in 2005, and it is the Turbotrain that made advances possible for the TGV. TGS (''Turbine à gaz spéciale'') Prototype – XR 8575 trainset In 1967, the SNCF converted a 2-car X 4300 Class diesel multiple unit train originally built by ANF Industrie (Ateliers Construction du Nord de la France) starting in 1963 (either train number X4375 or X4365), into the prototype experimental Turbotrain TGS (''Turbine à gaz spéciale'').Garvin, Brian; Fox, Peter; and Appleby, Chris.

SNCF
The Société nationale des chemins de fer français (, , SNCF ) is France's national State-owned enterprise, state-owned railway company. Founded in 1938, it operates the Rail transport in France, country's national rail traffic along with that of Monaco, including the TGV, on France's high-speed rail network. Its functions include operation of railway services for passengers and freight (through its subsidiaries SNCF Voyageurs and Rail Logistics Europe), as well as maintenance and signalling of rail infrastructure (SNCF#Divisions, SNCF Réseau). The railway network consists of about of route, of which are high-speed lines and electrified. About 14,000 trains are operated daily. In 2010 the SNCF was ranked 22nd in France and 214th globally on the Fortune Global 500, ''Fortune'' Global 500 list. It is the main business of the SNCF Group, which in 2020 had €30 billion of sales in 120 countries. The SNCF Group employs more than 275,000 employees in France and around the worl ...

Gas Turbine Locomotive
A gas turbine locomotive is a type of railway locomotive in which the prime mover is a gas turbine. Several types of gas turbine locomotive have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels (drivers). A gas turbine train typically consists of two power cars (one at each end of the train), and one or more intermediate passenger cars. A gas turbine offers some advantages over a piston engine. There are few moving parts, decreasing the need for lubrication and potentially reducing maintenance costs, and the power-to-weight ratio is much higher. A turbine of a given power output is also physically smaller than an equally powerful piston engine, so that a locomotive can be extremely powerful without needing to be inordinately large. However, a gas turbine's power output and efficiency both drop dramatically with rotational speed, unlike a piston engine, which has a comparatively flat power curve. This makes gas turbine� ...

British Rail APT-E
The APT-E, for Advanced Passenger Train Experimental, was the prototype Advanced Passenger Train tilting train unit. It was powered by gas turbines, the only multiple unit so powered that was used by British Rail. The APT-E consisted of two driving power cars (PC1 and 2) and two trailer cars (TC1 and 2). Each power car was equipped with four Rover-built Leyland 2S/350 gas turbines (and a fifth for auxiliary power supplies), which initially produced 300 hp each but were progressively uprated to 330 hp. Two GEC 253AY nose suspended traction motors provided the traction on the leading bogies. The vehicles were manufactured from aluminium and were approximately , with articulated bogies between them. The APT-E made its first run on 25 July 1972 from Derby to Duffield and was immediately 'blacked' by the drivers' union ASLEF, due to concerns that the single driver's seat pre-empted ongoing negotiations about the single-manning of trains. It was over twelve months before it ran a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...
