Turin–Lyon High-speed Railway
The Turin–Lyon high-speed railway is an international rail line under construction between the cities of Turin and Lyon. It is intended to link the High-speed rail in Italy, Italian and TGV, French high-speed rail networks and will be long. The core of the project is its international section, which will cross the Alps through the Mont d'Ambin Base Tunnel between the Susa Valley in Piedmont and Maurienne in Savoie. At , that tunnel will be the List of longest tunnels, longest rail tunnel in the world, ahead of the Gotthard Base Tunnel. The estimated total cost of the line is Euro, €25 billion, of which €8 billion is for the international section, which is the only part of the line where work has started. Like the Swiss NRLA project, the line has twin aims of transferring freight traffic across the Alps from trucks to rail to reduce air pollution and CO2 emissions and of providing faster passenger transport to reduce air traffic. The new line will considerably shorten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Track
A double-track railway usually involves running one track in each direction, compared to a single-track railway where trains in both directions share the same track. Overview In the earliest days of railways in the United Kingdom, most lines were built as double-track because of the difficulty of co-ordinating operations before the invention of the telegraph. The lines also tended to be busy enough to be beyond the capacity of a single track. In the early days the Board of Trade did not consider any single-track railway line to be complete. In the earliest days of railways in the United States most lines were built as single-track for reasons of cost, and very inefficient timetable working systems were used to prevent head-on collisions on single lines. This improved with the development of the telegraph and the train order system. Operation Handedness In any given country, rail traffic generally runs to one side of a double-track line, not always the same side a ...

Euro
The euro ( symbol: €; code: EUR) is the official currency of 19 out of the member states of the European Union (EU). This group of states is known as the eurozone or, officially, the euro area, and includes about 340 million citizens . The euro is divided into 100 cents. The currency is also used officially by the institutions of the European Union, by four European microstates that are not EU members, the British Overseas Territory of Akrotiri and Dhekelia, as well as unilaterally by Montenegro and Kosovo. Outside Europe, a number of special territories of EU members also use the euro as their currency. Additionally, over 200 million people worldwide use currencies pegged to the euro. As of 2013, the euro is the second-largest reserve currency as well as the second-most traded currency in the world after the United States dollar. , with more than €1.3 trillion in circulation, the euro has one of the highest combined values of banknotes and coins in c ...

Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through hard rock, wet or dry soil, or sand. Tunnel diameters can range from (micro-TBMs) to to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs. TBMs can be designed to excavate non-circular tunnels, including u-shaped, horseshoe, square or rectangular tunnels. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in urban areas. The major disadvan ...

Schist
Schist ( ) is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture (geology), texture reflects a high content of platy minerals, such as micas, talc, chlorite group, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building (orogeny) and usually reflects a medium Metamorphism#Metamorphic grades, grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schist''). Where the type of the original rock (the protolith) is discernible, the schist is us ...

Susa, Piedmont
Susa ( lat, Segusio, french: Suse, frp, Suisa) is a town and ''comune'' in the Metropolitan City of Turin, Piedmont (Italy), Piedmont, Italy. In the middle of Susa Valley, it is situated on at the confluence of the Cenischia with the Dora Riparia, a tributary of the Po River, at the foot of the Cottian Alps, 51 km (32 mi) west of Turin. History Susa ( la, Segusio) was founded by the Ligures. It was the capital of the Segusini (also known as Cottii). In the late 1st century BC it became voluntarily part of the Ancient Rome, Roman Empire. Remains of the Roman city have been found in the excavations of the central square, the Piazza Savoia. Susa was the capital of the province of Alpes Cottiae. According to the medieval historian Rodulfus Glaber, Susa was "the oldest of Alpine towns". In the Middle and Modern ages, Susa remained important as a hub of roads connecting southern France to Italy. Taking part of the county or march of Turin (sometimes "march of Susa"). In 1167 ...

Court Of Audit Of France
The ''Cour des Comptes'' ("Court of Accounts") is France's supreme audit institution, under French law an administrative court. As such, it is independent from the legislative and executive branches of the French Government. However, the 1946 and 1958 French constitutions made it the Court's duty to assist the Cabinet and Parliament in regulating government spending. The Court thus combines functions of a court of exchequer, comptroller general's office, and auditor general's office in common-law countries. It is also a Grand Corps of the French State and mainly recruits among the best-ranked students graduating from the Ecole nationale d'administration. The Court traces its origins back to the Middle Ages and views itself as succeeding the Court of Auditors of Paris, permanently established in the early 14th century. It was re-established in 1807 by Napoleon. Its three duties are to conduct financial audits of accounts, conduct good governance audits, and provide information ...

Trans-European Conventional Rail Network
The Trans-European conventional rail network, together with the Trans-European high-speed rail network, make up the Trans-European Rail network, which in turn is one of a number of the European Union's Trans-European transport networks (TEN-T). It was defined by the Council Directive 2001/16/EC of 19 March 2001. The aim of this EU Directive is to achieve the interoperability of the European conventional rail network at the various stages of its design, construction and operation. The network is defined as a system consisting of a set of infrastructures, fixed installations, logistic equipment and rolling stock. By definition of the EC decision, the conventional rail network may be subdivided into the following categories: * lines intended for passenger services * lines intended for mixed traffic (passengers and freight) * lines specially designed or upgraded for freight services * passenger hubs * freight hubs, including inter-modal terminals * lines connecting the components me ...

High-speed Railway
High-speed rail (HSR) is a type of rail system that runs significantly faster than traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above or upgraded lines in excess of are widely considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains mostly operate on standard gauge tracks of continuously welded rail on grade-separated rights of way with large radii. However, certain regions with wider legacy railways, including Russia and Uzbekistan, have sought to develop a high speed railway network in Russian gauge. There are no narrow gauge high-speed trains; the fastest is the Cape gauge Spirit of Queensland at . Many countries have developed, or are currently building, high-speed rail infrastructure to connect major cit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
