Adif Launches EUR 102.54 Million Safety Upgrade for Madrid C-5 Tunnel Network

MADRID, June 2026 — The Madrid C-5 corridor serves as a vital artery for the region's transport network, transporting approximately 72 million passengers annually. Ensuring the operational integrity and safety of this high-traffic route is paramount for the efficiency of the broader urban rail system.

The current project involves a EUR 102.54 million investment dedicated to improving safety and evacuation infrastructure. The scope encompasses the Atocha–Las Águilas, Méndez Álvaro, Doce de Octubre, and Puente Alcocer tunnels, with specific plans for 12 new emergency exits, safety zones, and enhanced ventilation in the Atocha–Las Águilas section. Additionally, the tender includes the installation of LED lighting, CCTV, fire hydrants, intrusion detection, and updated communication systems.

For industry stakeholders, the integration of civil engineering works with safety system installations represents a strategic approach to minimizing operational downtime. By coordinating these elements as a single package, Adif aims to execute the upgrades without disrupting active train services, a critical requirement for maintaining urban mobility.

This project is a component of a larger EUR 1.35 billion modernization program for the C-5 line. While EUR 650 million is allocated to infrastructure managed by Adif, the remaining funds are earmarked for the modernization of workshops and the procurement of new rolling stock.

These developments reflect a broader European trend toward the rigorous upgrading of aging rail infrastructure to meet contemporary safety and capacity demands, ensuring the longevity of urban transit networks.
