High-speed rail?is a type of?rail transport?that operates significantly faster than traditional rail traffic, using an integrated system of specialized?rolling stock?and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of 250?km/hr and existing lines in excess of 200?km/hr are widely considered to be high-speed, with some extending the definition to include much lower speeds (e.g. 160?km/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 the?bullet train. High-speed trains normally operate on?standard gauge?tracks 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. Only in Europe does HSR cross international borders. China has 16,000?km of HSR, accounting for 60 percent of the world’s total. While high-speed rail is usually designed for passenger travel, some high-speed systems also offer?freight?service.
