Safety and circulation
Electromechanical, electronic and automated systems technologies for railway circulation and operational support
Driver support technologies
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:
- management of railway circulation in stations, at crossroads and in the other service areas, enabling to work in safety on points, signals, etc. as regards tracks appointed to each train;
- separation between trains, thus enabling to keep a safe distance between one train and another along the lines (technological separation systems such as: BA=Automatic Block; BAB=automatic block signalling; BCA= sleeper counting block; BCAB= sleeper counting block signalling; BR= radio block for high-speed and high-capacity lines [BA= blocco automatico; BAB= blocco automatico banalizzato; BCA= blocco conta assi; BCAB= blocco conta assi banalizzato; BR= blocco radio per linee AV/AC];
- train gear protection that includes the following technologies: Drive Aid Systems called SSC - Sistema di Supporto alla Condotta, the train Control System called SCMT - Sistema Controllo Marcia del Treno and ERTMS - European Rail Train Management System;
- supervision and remote control of railway circulation;
- protection of railway circulation in points intersecting road networks (level crossing);
- acquisition and transfer of land and on board information.
Technologies for operational support
Among the various technological systems fundamental for the functioning of the railway infrastructure, it is important to mention the following:
- support provided to the computerized management of the maintenance processes (maintenance platform) and the circulation processes (circulation platform, functional among other things to providing information to the public concerning trains as well as the commercial relationship with railway Companies);
- remote control of the electric traction fixed systems enabling to intervene from centralized positions on transmission, transformation, conversion and distribution processes of the electric energy necessary for the traction of the means circulating on the network (DOTE);
- video surveillance of the most important assets of the network (traits of railway, tunnels, bridges, stations, etc.), fundamental for guaranteeing continuity and efficiency to railway circulation, but also to increase travellers’ security at stations.
