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).
Higher-speed rail
In October 2013, the Minister of Railways announced at the two-day international technical conference on "High Speed Rail Travel; Low Cost Solution" that the focus of India's rail improvement is to implement a lower cost solution to meet the immediate needs by providing higher-speed rail services as an incremental step before the dedicated track high-speed rail can be achieved. India's higher-speed rail will be in the range of . On 3 July 2014, a trail run with the new top speeds of was successfully completed on a journey of between Delhi and Agra. The new service, operational since 5 April 2016, cut the travel time by 126 minutes (compared to standard trains) with a top speed of down to 99 minutes.
