The devices and systems for a safe railway circulation currently used on the Italian network are diversified and integrated among each other depending on the characteristics of the lines and the type of traffic managed on the same (passengers or goods; long, medium or short distance) and they guarantee:
Among the various technological systems fundamental for the functioning of the railway infrastructure, it is important to mention the following:
The European Rail Traffic Management System (ERTMS) is the advanced safety system for spacing trains, able to manage and control rail traffic. Operating in Italy for over ten years on the High Speed/High Capacity lines, the ERTMS system represents one of the most important innovations introduced in recent years in the panorama of railway signalling.
ERTMS favours interoperability between railway operators from various countries, based on information exchanged between the subsystem on the ground and on-board. The data and information transmitted allows the train’s speed to be continuously monitored, providing the train operator with all information necessary for its safe operation, and with the emergency braking system being activated in the event that all parameters are not respected and the train’s speed exceeds the permissible limit.
In Italy, there are over 700 kilometres of line today equipped with ERTMS technology along the Turin–Milan–Bologna–Florence–Rome–Naples–Salerno vertical axis.
