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 highway construction programme in its final stages, the Croatian parliament has passed a bill to build its first high-speed line, a new Botovo–Zagreb–Rijeka line, with an initial maximum planned speed of 250 km/h. Initially, however, the train will not exceed 200kmh due to a signaling system which can only accommodate speeds up to 200kmh. The cost of the new line is estimated at 9,244,200,000 kuna (approx. 1.6 bil USD). The project will include the modernisation of the current Botovo-Zagreb line and a construction of a completely new line between Zagreb and Rijeka.
