Thanks for the information. I looked up ERTMS :
Quote:
ERTMS has two basic components
ETCS, the European Train Control System, is an automatic train protection system (ATP) to replace the existing national ATP-systems;
GSM-R, a radio system for providing voice and data communication between the track and the train, based on standard GSM using frequencies specifically reserved for rail application with certain specific and advanced functions. For more information on GSM-R, please visit: http://gsm-r.uic.asso.fr
ERTMS aims at replacing the different national train control and command systems in Europe. The deployment of ERTMS will enable the creation of a seamless European railway system and increase European railway's competitiveness.
