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.
Planned high-speed rail by country
Research on high-speed rail systems based on magnetic levitation have been ongoing since the 1970s, led by JR Central. 
The trains and guideways are technologically ready and over 100,000 people have ridden them. 
Pre-series L0 series trains on the Yamanashi Test Line have reached speeds of (crewed), making them the fastest trains in the world. 
The Yamanashi test track is to be incorporated into the under construction Tokyo–Osaka maglev route.
