High speed rail
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. 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.
High Speed Rail can be found in countries including China, Britain, France and Germany. The first country to have HSR was Japan with its Shinkansen System. As defined by Europe and the International Union of Railways (UIC), generally high-speed rail is a set including high-speed rolling-stock and a dedicated high-speed line.
