What is high -speed rails?
High -speed railways refers to trains traveling on special lines in more than 200 km/h (125 mph). The International Railway Union describes a high -speed train as a one that travels faster than 250 km/h (155 mph) on reserved footsteps or 200 km/h on upgraded conventional footsteps. High -speed trains are most used in Japan and France, but each of China and the United States have one and considering further adoption. Other countries with high-speed trains include Belgium, Germany, Italy, Portugal, South Korea, Spain, Taiwan and the United Kingdom. The first high -speed train in the world was Tōkaidō Shinkansen, which started in October 1964, which traveled between Tokyo and Osaka in Japan.
The latest high -speed rail research includes the use of maglev compositions where the magnets are carefully arranged to allow the train to truly float above the tracks. This is relatively expensive, but significantly reduces friction and increases the possible top speed. JapoThe Maglev train, JR-Maglev MLX01, reached 361 MPH (580.9 km / h) in 2003 and set a record for the fastest train. The record for conventional railway trains was set by French TGV, trained by Grande Vitesse, , which reached 3 April 2007 357.2 mph (574.8 km/h).
High -speed trains are an effective form of transport in areas where the population density is at a high level and distances are long but not too long. This explains their acceptance in France and Japan. Longer preparation times associated with leaving the airport, security, loading, loading, trading and take -off, high -speed trains make an attractive alternative to air travel under certain circumstances. Proposals for high -speed train development between Boston, New York and Washington, D.C., on the east coast and San Francisco and Sacramento in Kalifornia were submitted.
some advantages high -speedLine trains over air transport are larger capacities, smaller fuel expenses, lower costs, less pollution and better security. It is generally believed that high -speed trains have defeated aircraft that have comfort for trips within 3 hours. For a high -speed train, which moves at a speed of 300 km / h (186 km / h) or 400 km / h (249 mph), this can expand to significant distances. Capital costs of investing in a new high -speed rail system and building reserved tracks cause investors on the basis of these proposals to be a problem on the basis of nuclear energy.
