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).
Planned high-speed rail by country
Research on high-speed rail systems based on magnetic levitation have been ongoing since the 1970s, led by JR Central. 
The trains and guideways are technologically ready and over 100,000 people have ridden them. 
Pre-series L0 series trains on the Yamanashi Test Line have reached speeds of (crewed), making them the fastest trains in the world. 
The Yamanashi test track is to be incorporated into the under construction Tokyo–Osaka maglev route.
