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 is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. "High-speed" is defined by the European Union as at least 250 km/h on new tracks, and 200 km/h on older tracks. The first high-speed train in the world was the Tōkaidō Shinkansen in Japan, whose service started in 1964, with the maximum speed 210 km/h.
