High-speed railis a type ofrail transportthat operates significantly faster than traditional rail traffic, using an integrated system of specializedrolling stockand dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of 250km/hr and existing lines in excess of 200km/hr are widely considered to be high-speed, with some extending the definition to include much lower speeds (e.g. 160km/hr) in areas for which these speeds still represent significant improvements.The first such system began operations in Japan in 1964 and was widely known as thebullet train. High-speed trains normally operate onstandard gaugetracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design.
Many countries have developed high-speed rail to connect major cities, including Austria , Belgium, China, France, Germany, Italy, Japan, Poland, Portugal, Russia, South Korea, Sweden, Taiwan, turkey, United Kingdom, United States and Uzbekistan.
