Adif will invest 14 million euros in the modernization of the catenary of the metric width network of Cantabria; a new action framed in the Proximity Plan, which will increase the reliability of the electrification systems, improve the response to possible incidents and facilitate maintenance tasks.
In addition to the renovation of all catenary disconnectors in the network, it has been integrated into a remote control system, which will allow automatic and integrated monitoring and control of these devices.
The works - which include all the operations of installation and integration of the equipment, supplies, assembly, configuration and start-up - will be carried out by the UTE integrated by Electrén and Elecnor Servicios y Proyectos.
The catenary disconnectors are devices that allow an electrical circuit to be mechanically separated from its power supply, isolating it in a section of the line. In this way, it is possible to preserve the safety of the work in the electrical network or to delimit a part of the catenary with incidents so that the circulation continues in the rest of the network.
The action is in addition to other ongoing initiatives in the field of electrification of the network, such as the new substations of Santander, Virgen de la Peña (both in project) and Requejada (in execution) and contribute to the achievement of Sustainable Development Goal (SDG) 9, which promotes reliable, sustainable and quality infrastructures.
Metric Width Network Modernization
Adif has mobilized more than 883 million euros from the Proximity Plan of Cantabria. Of these, 626.6 million correspond to the metric width network.
To increase the reliability of the network, track and infrastructure renovation actions are addressed, such as those that will be undertaken soon in the Santander-Cabezón de la Sal and Santander-Orejo sections; signaling works with the renovation of interlocks and telecommunications, such as the new automatic blockade banalized between Torrelavega - Santander-Nueva Montaña and Maliaño - Astillero, as well as new blockages between Torrelavega and Cabezón de la Sal; and improvement of the catenary with remote control of disconnectors and new substations, once the Orejo-Liérganes line has been modernized.
