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
With the development of the HSR-350x, South Korean media argue that Korea came to be the fourth nation to develop high-speed rail independently, and the seventh nation to acquire the technology. However, the statistics should vary according to the multiple definitions of a high speed rail. The "High Speed Rail 350x" went under development by South Korean engineers several years before the French technology-transfer program.  The train is a product of nearly 10 years of research and development by the Korean company Rotem and the National Rail Technology Institute of Korea.
Called the "Korean G-7" (a direct reference to Korea's ambitions of joining the technological prowess of G-7 nations) this technology is currently in its test-run phase and is scheduled for initial passenger operation through the Seoul-to-Gwangju sector by 2007. The proposed train would run faster than the TGV, at 350 km/h as opposed to 300 km/h. The Korean G-7 incorporates several technologies the French TGV doesn't, including an aluminum body, digital traffic control, and a pressure compensation system. When operational the Korean G-7 will also allow passengers to rotate their seats, giving them the choice of a forward-facing or a rear-facing seat, in response to the many complaints about the fixed one-directional seating arrangements on the KTX.
