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).
HEMU-430X
HEMU-430X (standing for High-Speed Electric Multiple Unit 430 km/h eXperimental) is a South Korean high-speed train intended for a maximum speed of . On March 31, 2013, it achieved 421.4 km/h in a test run, making South Korea the world's fourth country after France, Japan and China to develop a high-speed train running on conventional rail above 420 km/h. The main new feature of the train compared to older South Korean high-speed trains is distributed traction. The commercial version of the train, tentatively named KTX-III, would have entered regular service in 2015 with a top speed of , however as of 2018 the plan seems to be abandoned.
