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
With the highway construction programme in its final stages, the Croatian parliament has passed a bill to build its first high-speed line, a new Botovo–Zagreb–Rijeka line, with an initial maximum planned speed of 250 km/h. Initially, however, the train will not exceed 200kmh due to a signaling system which can only accommodate speeds up to 200kmh. The cost of the new line is estimated at 9,244,200,000 kuna (approx. 1.6 bil USD). The project will include the modernisation of the current Botovo-Zagreb line and a construction of a completely new line between Zagreb and Rijeka.
