The removal of the telephone block signalling system on the Cotos–Cercedilla railway section involves the comprehensive modernisation of signalling systems by replacing an operational model based on telephone communications with a more advanced and safer technological solution.
The project consists of upgrading railway control and operational systems through the elimination of the telephone block system and the implementation of a modern signalling solution.
The scope includes the installation of automatic train detection systems, new signalling equipment, trackside technical assets, and the adaptation of power supply and telecommunications infrastructure.
