Swissmetrois a proposedSwisstransportation system based on vacuum-train (also known asvactrain) technology.[1]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
editThe Swissmetro project was presented in a special report[2]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 theTransrapidof 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 betweenBernandZürichwould have been reduced from around 1 hour by intercity train or motorcar to a mere 12 minutes with Swissmetro.
Objectives
editThe objectives were to connect Swiss urban centres with a fast, modern, sustainable, transport system and reduce or even eliminate the congestion on the Swiss highways and railways without negatively impacting the Swiss landscapes and cities.
History
editThe system was developed by Swissmetro Ltd., with Swiss senator of the Canton of Ticino, Dr.Sergio Salvioni[3]as president. The research and development were led byEPFLProfessor Marcel Jufer. This was done by the Swiss Federal Institutes of Technology (EPFL andETHZ) and Swiss engineering and industrial companies with some financial support of the Swiss Federal Government.[4][5]The project was ready to be implemented and an application for a concession for a pilot track between Geneva and Lausanne was made in 1998. At this time, however, the Swiss Federal Government was already fully absorbed with large national infrastructure projects (Rail 2000,Gotthard AlpTransit,etc.). In addition, the Swiss Federal office of Transportation (BAV-EVED) had some reservations (switch, capacity, safety, choice of the pilot track, financial concepts, etc.).[6]
Swissmetro-NG
editSwissMetro-NG is the modern version of the original project. It is, so to speak, the version 2.0, which was proposed by the Swiss Transportation Research Institute.[7]Air resistance and aerodynamic problems are eliminated altogether by removing all of the air in the tunnels. The tunnel diameter and consequently the overall costs are significantly reduced (around 50%). A new switch allows a drive-through operation without stopping. Long vehicle compositions with high capacities (over 1200 seats) as well as an extraordinarily high performance (supersonic) become possible. The reservations of the BAV-EVED are resolved.
The conditions for the resumption of the Swiss project are now very favourable (completion ofRail 2000and Gotthard Alptransit, low interest rates, new technical advances, etc.). In addition, SwissMetro-NG meets all possible requirements regardingCO
2emissions, landscape protection, speed, sustainability, tourism, capacity, safety, costs, network capability, economic efficiency, etc. and it has proponents from all political colours and all corners of the country. The non-profit SwissMetro-NG association[8][9]is promoting the project.
In 2017, Konrad Graber, Swiss senator of theCanton of Lucernebrought the SwissMetro-NG project to the attention of Parliament. It was positively received and decisions in its favour are being made.[10][11][12]It is now becoming increasingly likely that SwissMetro-NG will be realized.[citation needed]
Because of its high performance and capacity, the system can draw traffic away from short-haul aviation and intercity highways and thus reduceCO
2emissions whilst simultaneously improving the transportation services. The travel time between the major Swiss cities, e.g. Geneva to Bern or Bern to Zürich, will be reduced to 12 minutes. In comparison, it still requires over 3 hours to traverse Switzerland today, independent of the mode of transportation and despite the small size of the country.
By exporting the system and the components, Switzerland will be able to help reduceCO
2emissions of intercity and transcontinental transportation on a global scale.
