Testo in inglese
The ETCS is the future of railway signalling system and is the automatic train travel control and protection system of today. The first application of the ETCS in the world is on the two italian railway lines Roma - Naples and Milan - Turin. This book, describing the above projects, is an initial and rapid means of communicating the new concepts, investigating the general characteristics on the ETCS system and offering professional updating opportunities for all those who wish to understand more about this fascinating issue.
