FCC Industrial will implement a Single Track Automatic Block (BAU) system on the Bobadilla-Ronda section (Cádiz). This operation will contribute to improving the reliability of the facilities and the quality of the service. An advanced signaling and telecommunications system will be installed on the entire Bobadilla-Algeciras line, since the new action will mean the removal of the telephone block on the Bobadilla-Ronda section, 70.5 kilometers long. The new system will work with Centralized Traffic Control (CTC) and will be implemented throughout the railway line, as it is already installed between Ronda and Algeciras (105.5 kilometers). The works, which involve modifications to signalling, energy and telecommunications installations and the installation of new state-of-the-art electronic interlocks.

The main actions to be carried out are the following: replacement of the electrical interlocking in Bobadilla and the interlockings in Campillos, Almargen and Cañete La Real and Setenil with electronic ones and the provision of Automatic Single Track Blocking (BAU) throughout the section.
