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).
Transport in Italy
The main public operator of high-speed trains ("alta velocità AV", formerly Eurostar Italia) is Trenitalia, part of FSI. Trains are divided into three categories: Frecciarossa ("Red arrow") trains operate at a maximum of 300 km/h on dedicated high-speed tracks; Frecciargento (Silver arrow) trains operate at a maximum of 250 km/h on both high-speed and mainline tracks; Frecciabianca (White arrow) trains operate at a maximum of 200 km/h on mainline tracks only.
