WebETCS-3, where the train travels at a speed up to 350 km/h and it is thus necessary to guarantee a continuous supervision of train position and speed. When the call is lost, the train has to automatically reduce the speed to 300 km/h (ETCS-1) or lower. We briefly discuss in the following the most typical HSR-specific services offered by GSM-R [9]:
