Answer: What is High Speed Rail mean?
High-speed rail (HSR) is a type of rail transport that runs significantly faster than traditional rail traffic, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, purpose-built lines in excess of 250 km/h (155 mph) and upgraded lines in excess of 200 km/h (124 mph) 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 (representing virtually the only standard gauge mainline railways in countries like Japan, Spain or India) tracks of continuously welded rail on a grade-separated right-of-way that incorporates a large turning radius in its design. However, certain regions with wider legacy railways, such as parts of the former Russian Empire (including Russia and Uzbekistan), have sought to develop a high speed railway network in Russian gauge. Thus far no high speed rail is planned or has been built on narrow gauge with the Spirit of Queensland achieving the highest top speed in revenue service on Cape gauge at 160 km/h.
Many countries have built and developed, or are currently building, high-speed rail infrastructure to connect major cities, including Austria, Belgium, China, Denmark, Finland, France, Germany, India, Indonesia, Italy, Japan, Morocco, the Netherlands, Norway, Poland, Portugal, Russia, Saudi Arabia, South Korea, Spain, Sweden, Switzerland, Taiwan, Turkey, the United Kingdom, the United States and Uzbekistan. Only in Europe does high-speed rail cross international borders. China has built over 37,900 km (23,500 mi) of high-speed rail, accounting for more than two-thirds of the world's total.
High-speed rail is the fastest ground-based method of commercial transportation. China has the fastest conventional high-speed rail in regular operation, with the Beijing–Shanghai high-speed railway reaching up to 350 km/h (217 mph). The Shanghai Maglev Train, opened in 2004, is the fastest commercial passenger maglev in operation, at 431 km/h (268 mph). In 2007, a Euroduplex TGV train broke a record of 574.8 km/h (357.2 mph), making it the fastest conventional wheeled train in the world. The Chuo Shinkansen in Japan is a maglev line under construction from Tokyo to Osaka at commercial speeds of 505 km/h (314 mph), with operations due to start in 2027.
