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).
Rail transport in Italy
High-speed trains were developed during the 1960s. E444 locomotives were the first standard locomotives capable of top speed of , while an ALe 601 electrical multiple unit (EMU) reached a speed of during a test. Other EMUs, such as the ETR 220, ETR 250 and ETR 300, were also updated for speeds up to . The braking systems of cars were updated to match the increased travelling speeds.
