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 East Asia
The Shanghai Maglev Train, a turnkey Transrapid maglev project, imported from Germany, is capable of an operational speed of 430 km/h and of a top speed of 501 km/h. It has connected Shanghai and Pudong International Airport since March, 2004. In April 2007, China opened several high speed rail lines between major cities, providing a network of 6,003 km, making it the world's largest high speed rail network. By 2012, China will have a 110,000 km rail network. Of that amount 13,000 km will be high speed rail, some line capable of going over 350 km/h, making CRH the largest, fastest, most technologically advanced high speed rail system in the world. 
However, the Maglev line has suffered from low ridership, and various expansion plans (e.g. to Hangzhou) remain stalled.
