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).
Higher-speed rail
In Australia, the track condition before the Regional Fast Rail project could only support trains up to speeds of . The tracks are with mixture of wooden and concrete ties. The rail weight varies but with majority being . The track upgrade in the project included changing to use concrete ties and to use new standard of rail weight at in order to support the new top speeds of .
