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).
List of high-speed railway lines in China
In 2008, the Ministry of Railways announced plans to build of high-speed railways with trains reaching normal speeds of 350 km/h. China invested $50 billion on its high-speed rail system in 2009 and the total construction cost of the high-speed rail system is $300 billion. The main operator of regular high-speed train services is China Railway High-Speed (CRH).
