High-speed Rail In France
The first French high-speed rail line opened in 1981, between Paris's and Lyon's suburbs. The LGV Sud-Est was at that time the only high-speed rail line in Europe. As of June 2021, the French high-speed rail network comprises 2,800 km of ''Lignes à grande vitesse'' (LGV). Tracks The newest high-speed lines allow speeds of in normal operation: originally LGVs were defined as lines permitting speeds greater than , revised to . Like most high-speed trains in Europe, TGVs also run on conventional tracks (french: link=no, lignes classiques), at the normal maximum speed for those lines, up to . This allows them to reach secondary destinations or city centres without building new tracks all the way, reducing costs compared to the magnetic levitation train project in Japan, for example, or complete high-speed networks with a different gauge from the surrounding conventional networks, in Spain and Japan, for example. Track design TGV track construction has a few key differenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris - TGV
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelligen ...

International Union Of Railways
The International Union of Railways (UIC, french: Union internationale des chemins de fer) is an international rail transport industry body. History The railways of Europe originated as many separate concerns, and there were many border changes after World War I and the Treaty of Versailles. Colonial railways were the responsibility of the mother country. Into this environment the UIC was created on 17 October 1922, with the aim of standardising industry practices. Ticket revenue sharing was originally undertaken with the UIC Franc currency equivalent. UIC classification and UIC Country Codes allowed precise determination of rolling stock capabilities and ownership, with wagons assigned unique UIC wagon numbers. The 1990s GSM-R radio telecommunication system is an international interoperability specification covering voice and signalling systems for railway communications whose specification is maintained by the International Union of Railways project European Rail Traf ...

25 KV AC
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons why it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance distances required where it ran under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance t ...

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. 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, or a third rail mounted at track level and contacted by ...

Train Path
A train path is the infrastructure capacity needed to run a train between two places over a given time-period.Definition froDirective 2001/14/EC Article 2 (l), of the European Parliament and of the Council Within the European Union, a train operator needs to purchase a train path from a rail infrastructure company to run a train In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often ... on their tracks. Overview The number of rail paths available on a given railway line depends on a number of factors. The number of tracks and the type of signalling, specifically the number of blocks, are limits set by the actual infrastructure. A variable factor is the speed difference between trains. Optimal capacity is achieved when all trains run at the same speed. When that is not the case, faster train ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HSL-Zuid
The HSL-Zuid ( nl, Hogesnelheidslijn Zuid, en, High-speed Line South), is a 125 kilometre-long (78 miles) Dutch high-speed railway line running between the Amsterdam metropolitan area and the Belgian border, with a branch to Breda, North Brabant. Together with the Belgian HSL 4 it forms the Schiphol–Antwerp high-speed railway. Originally scheduled to be in service by 2007, the first public operations began on 7 September 2009, after a ceremony on 6 September.

TGV Duplex
The TGV Duplex is a French high-speed train of the TGV family, manufactured by Alstom, and operated by the French national railway company SNCF. It is unique among TGV trains in that it features bi-level carriages. The Duplex inaugurated the third generation of TGV trainsets. It was specially designed to increase capacity on high-speed lines with saturated traffic. With two seating levels and a seating capacity of 508 passengers, the Duplex increases the passenger capacity. While the TGV Duplex started as a small component of the TGV fleet, it has become one of the system's workhorses. Purpose The LGV Sud-Est from Paris to Lyon is the busiest high-speed line in France. After its opening in 1981 it rapidly reached capacity. Several options were available to increase capacity. The separation between trains was reduced to three minutes on some TGV lines, but the increasingly complex signalling systems, and high-performance brakes (to reduce braking distance) required, limit ...

Axle Load
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a '' spindle''. Terminology On cars and trucks, several senses of the word ''axle'' occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an ''axle'' or ''axle shaft''. However, in looser usage, an entire assembly including the surrounding axle housing (typically a casting) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
