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 India
The Indian Ministry of Railways' white-paper "Vision 2020", submitted to Indian Parliament on 18 December 2009, envisages the implementation of regional high-speed rail projects to provide services at 250–350 km/h, and planning for corridors connecting commercial, tourist, and pilgrimage hubs. Six corridors have been identified for technical studies on setting up of high-speed rail corridors: Delhi–Chandigarh–Amritsar, Pune-Mumbai-Ahmedabad, Chennai-Vijayawada-Dornakal-Kazipet-Hyderabad, Howrah–Haldia, Chennai-Bangalore-Coimbatore-Kochi-Thiruvananthapuram, Delhi-Agra-Kanpur-Lucknow-Varanasi-Patna. These high-speed rail corridors will be built as elevated corridors.
