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 Italy
Service on the high speed lines is provided by Trenitalia and privately owned NTV. Several types of high-speed trains carry out the service:Current limitations on the tracks set at the maximum operating speed of the trains. Along with the development of ETR 1000 by AnsaldoBreda and Bombardier Transportation (which is designed to operate commercially at , with a technical top speed of over ), Rete Ferroviaria Italiana is working on the necessary updates to allow trains to speed up to . On May 28th, 2018, the Ministry for Infrastructures and Transportation and the National Association for Railway Safety decided not to run the 385 km/h tests required to allow commercial operation at 350 km/h, thus limiting the maximum commercial speed on the existing Italian high-speed lines to 300 km/h. .
