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 Sweden
There are plans for long completely new high-speed railways Stockholm–Linköping–Jönköping–Borås–Gothenburg ("Götalandsbanan") and Jönköping–Helsingborg–Copenhagen ("Europabanan" for the Swedish part), since the existing railways are relatively congested, with mixed 200 km/h passenger trains, slower regional trains and even slower cargo trains. The plans say that the new railways would be built similar to the French TGV-lines with long curve radii and relatively steep inclines allowing for speeds between 300–320 km/h with non-tilting trains, dedicated for high-speed passenger trains.
