Swissmetro
''Swissmetro'' is a proposed Swiss transportation system based on vacuum-train (also known as vactrain) technology. It was invented by Swiss engineer Rodolphe Nieth in 1974 and it is presently being promoted and developed as SwissMetro-NG ("NG" for New Generation). Technology The Swissmetro project was presented in a special report by Rodolphe Nieth, Martin Steiger and Jean-Francois Braillard in 1980. It proposed vehicles travelling at very fast speeds in a network of underground tunnels. Rolling resistance was eliminated with magnetic levitation, as in the Transrapid of Germany and air resistance was reduced by lowering the air pressure in the tunnels to around 10% of the normal atmospheric pressure. Propulsion was electrical (linear motors). The travel time between Bern and Zurich would have been reduced from around 1 hour by intercity train or motorcar to a mere 12 minutes with Swissmetro. Objectives The objectives were to connect Swiss urban centres with a fast, modern, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maglev
Maglev (derived from '' magnetic levitation''), is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction. Such trains rise approximately off the track. There are both high speed, intercity maglev systems (over ), and low speed, urban maglev systems ( to ) being built and under construction and development. With maglev technology, the train travels along a guideway of electromagnets which control the train's stability and speed. While the propulsion and levitation require no moving parts, the bogies can move in relation to the main body of the vehicle and some technologies require support by retractable wheels at low speeds under . This compares with electric multiple units that may have several dozen parts per bogie. Maglev trains can therefore in some cases be quieter and smoother than conventional trains and have ...

Sergio Salvioni
Sergio Salvioni (1927-2017) was a Swiss politician and a member of the Swiss Council of States from the Canton of Ticino. He was the son of Arturo and Erminia Salvioni and grandnephew of Prof. Carlo Salvioni, professor of philology and dialectology at the University of Pavia. Personal and political life Sergio Salvioni studied law at the Universities of Basel and Bern (1947–51), obtaining his doctorate in 1951 and completing specialised studies at the universities of Rome, Vienna and Berkeley, California. In 1953 he obtained a patent as a lawyer and notary and started a law office and notary in Locarno in 1962. In 1986, he was appointed by the Philippine government as legal representative in Switzerland for the recovery of funds (US$684 Million) deposited in the Swiss Confederation by the former Philippine President Ferdinand Marcos. This effort was successful, and it was honoured by the 15th Philippine President Benigno Aquino III with the "Presidential Medal of Merit" ...

Hyperloop
A hyperloop is a proposed high-speed transportion system for both public and goods transport. The idea was picked up by Elon Musk to describe a modern project based on the vactrain concept (first appearance in 1799). Hyperloop systems comprise three essential elements: tubes, pods, and terminals. The tube is a large, sealed and low-pressure system (usually a long tunnel). The pod is a coach pressurized at atmospheric pressure that runs substantially free of air resistance or friction inside this tube using magnetic propulsion (in some cases augmented by a ducted fan). The terminal handles pod arrivals and departures. The Hyperloop, in the initial form proposed by Musk, differs from vactrains by relying on residual air pressure inside the tube to provide lift by aerofoils and propulsion by fans. The hyperloop has its roots in a concept by George Medhurst in 1799 and subsequently developed under the names pneumatic railway, atmospheric railway or vactrain. Elon Musk renew ...

Vactrain
A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to . This is 5–6 times the speed of sound in Earth's atmosphere at sea level. 18th century In 1799, George Medhurst of London conceived of and patented an atmospheric railway that could convey people or cargo through pressurized or evacuated tubes. The early atmospheric railways and pneumatic tube transport systems (such as the Dalkey Atmospheric Railway) relied on steam power for propulsion. 19th century In 1888, Michel Verne, son of Jules Verne, imagined a submarine pneumatic tube transport system that could propel a passenger capsule at speeds up to under the Atlantic Ocean (a transatlantic tunnel) in a short story called "An Express of the Future". 20th century The vactra ...

Rail Transport In Switzerland
The Swiss rail network is noteworthy for its density, its coordination between services, its integration with other modes of transport, timeliness and a thriving domestic and trans-alp freight system. This is made necessary by strong regulations on truck transport, and is enabled by properly coordinated intermodal logistics. With network length, Switzerland has a dense railway network, and is the clear European leader in kilometres traveled: 2,505 km per inhabitant and year (2019). Worldwide only the Japanese travel more by train. Virtually 100% of its network is electrified, except for the few tracks on which steam locomotives operate for tourism purposes only. There are 74 railway companies in Switzerland. The share of commuters who travel to work using public transport (as main mode of transport) is 30%. The share of rail in goods transport performance by road and rail (modal split) is 39%. Switzerland was ranked first among national European rail systems in the 2017 Eur ...

SCMaglev
The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation (maglev) railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research Institute. On 21 April 2015, a manned seven-car L0 Series SCMaglev train reached a speed of , less than a week after the same train clocked , breaking the previous land speed record for rail vehicles of set by a JR Central MLX01 maglev train in December 2003. Technology The SCMaglev system uses an electrodynamic suspension (EDS) system. The trains' bogies have superconducting magnets installed, and the guideways contain two sets of metal coils. The current levitation system utilizes a series of coils wound into a "figure 8" along both walls of the guideway. These coils are also cross-connected underneath the track. As the train accelerates, the magnetic fields of its superconducting magnets induce a current into these coils due to the magnetic field induction effect. ...

High-speed Rail
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 majo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail 2000
Rail 2000 (German: ''Bahn 2000''; French: ''Rail 2000'', Italian: ''Ferrovia 2000'') is a large-scale project of the Swiss Federal Railways (SFR) established in 1987 to improve the quality of the Swiss rail network for the New millennium. It includes measures to accelerate a number of existing connections and the modernisation of rolling stock. The federal government decision to support the project in 1986 was approved by a referendum in 1987. In 2004 the first phase was completed consisting of around 130 projects with a budget of around CHF 5.9 billion. History Background After years of heavy investment in roads in the postwar years, the share of rail in the total passenger market in Switzerland had been significantly reduced by the end of the 1960s. At this time SFR decided that changes were necessary to increase rail patronage. More trains were operated in order to increase frequencies; this led to a 75% increase in passengers between 1971 and 1983 on the Bern–Zürich ...
