Punktförmige Zugbeeinflussung
After acknowledging the warning signal the train has to stay below the braking curve (German "Bremskurve") - fast trains may travel up to 165 km/h and they must reduce the speed to below 85 km/h after 23 seconds. Note that the operation of high speed trains beyond 165 km/h is not based on visual wayside signals or PZB inductors (using LZB or European Train Control System cab-signalling instead in Germany).
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.
