At the heart of the 'human factor' in crisis due to Urda: "In a degraded system, we are the last protection"

Adif operates 19 Control and Regulation Centers (CRC) across Spain, managing train traffic. In Madrid, Chamartín oversees conventional networks, while Atocha handles high-speed routes. Each CRC has a structured hierarchy, with a single traffic manager monitoring train movements through various screens. They set itineraries and ensure safety via a physical locking system. The LZB system, which failed during a recent accident, regulates train speed and distance. Operators face challenges due to complex regulations and lack of quick-reference guides, relying heavily on human judgment. Training for traffic managers includes theoretical and practical phases, with support from supervisors and technicians during incidents.
