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).
Beijing–Shanghai high-speed railway
Under former Minister of Railways Liu Zhijun, the railway line was the first one designed for a maximum speed of 380 km/h in commercial operations. The non-stop train from Beijing South to Shanghai Hongqiao was expected to finish the journey in 3 hours and 58 minutes, averaging , making it the fastest scheduled train in the world, compared to 9 hours and 49 minutes on the fastest trains running on the parallel conventional railway. But following Liu Zhijun's dismissal in February 2011, several major changes were announced. First, trains would be slowed to a maximum speed of , reducing operating costs. At this speed, the fastest trains would take 4 hours and 48 minutes to travel from Beijing South to Shanghai Hongqiao, making one stop at Nanjing South. Additionally, a slower class of trains running at would be operated, making more stops and charging lower fares. On September 21, 2017, 350 km/h operation was restored with the introduction of China Standardized EMU. This reduced travel times between Beijing and Shanghai to about 4 hours 24 minutes on the fastest scheduled trains, attaining an average speed of over a journey of making those services the fastest in the world.
