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 Europe
With the imminent entering into service of the ETR1000 trainsets, which have a top speed of more than 400 km/h and a commercial speed of 360 km/h, the rail network will be upgraded to safely allow trains to run at such speeds. The commercial run of the first ETR1000 is planned for 2014.
