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 East Asia
A Japanese consortium led by the Central Japan Railway Company have been researching new high-speed rail systems based on magnetic levitation since the 1970s. Although the trains and guideways are technologically ready and over 100,000 people have ridden them, high costs remains as barriers. Test trains SCMaglev MLX01 on the Yamanashi Test Line have reached speeds of 581 km/h (crewed), making them the fastest trains in the world. These new maglev trains are intended to be deployed on new Tokyo–Osaka Shinkansen maglev route, called the Chuo Shinkansen. On May 2011, JR Central announced the company will start operation of maglev route from 2027 between Tokyo–Nagoya followed by Nagoya–Osaka route by 2045. Projected travel time for Tokyo–Nagoya (286 km) is 40 minutes.
