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. While there is no single standard that applies worldwide, new lines in excess of and existing lines in excess of are widely considered to be high-speed, with some extending the definition to include lower speeds 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.
High-speed rail in Europe
Czech Railways have been running the Super City Pendolino from Prague to Ostrava since 2005. The Pendolino is capable of operating at , but trains that are in service are limited to 160 km/h due to the speeds the railways were constructed for. These limits may be raised in the future to , last parts of 4th transit corridor (Prague - České Budějovice) are already projected for . The railjet is also capable of 230 km/h and reaches that speed in Austria and Germany but is likewise limited to 160 km/h in the Czech Republic.
