Inside the Circulation Regulation Centers (CRC), operators manage complex railway networks through digital interfaces displaying train movements in schematic form. These facilities, considered critical infrastructure, require strict security clearance to access at strategic locations such as França station in Catalonia and Atocha in Madrid, the latter being Spain's largest CRC and recently highlighted following the Urda accident. Work is organized into specific control posts where an Adif operator manages a designated line or section, supported by colleagues as needed, while supervisors and room managers maintain oversight of all operations.
Under normal conditions with digital systems like ERTMS or LZB active, operators primarily supervise automatic regulation and electronic interlockings. However, when signaling systems fail, manual management is activated using lateral signal blocking (BSL) or the ASFA system. In these degraded scenarios, the CRC becomes the eyes of the driver, relying on regulatory phone messages known as "telefonemas" dictated via radio. A critical error in this communication process was identified as a factor in the recent accident, where an incorrect order permitted normal speed instead of restricting movement to 40 km/h under visual control.
The operational landscape has shifted significantly due to high staff turnover and a lack of experienced personnel. The CGT railway union criticizes the accelerated replacement strategy, noting that new hires often enter critical roles directly from outside the industry without prior field experience or sufficient training. Unlike train drivers, these operators do not pass Ministry of Transport or Aesf exams before starting; they undergo a six-month training course after securing their position through competitive exams to obtain circulation responsibility certification. This contrasts sharply with air traffic controllers, who face stricter entry requirements and higher salaries.
The Railway Circulation Union (SCF) highlights that understaffing coexists with an overwhelming workload that exceeds capacity. Since the liberalization of high-speed rail, the number of trains has increased while staffing levels have remained static. Recent protests outside Adif headquarters reflect growing unrest within the collective, exacerbated by public statements blaming individual workers and the leak of internal recordings. In the França station CRC, staff are frequently forced to double shifts to cover 24-hour operations across 14 posts, leading to accumulated fatigue from working 12-hour days in a high-alert environment where breaks are sometimes impossible.
These conditions raise questions regarding how a 17-minute window passed between an incorrect order and the collision without intervention. Industry executives point to a misalignment of priorities within Adif, suggesting that hyper-regulation has shifted focus toward risk analysis teams rather than daily problem-solving and maintenance. This concern echoes previous incidents like Adamuz, questioning whether infrastructure investment matches the demands of a liberalized corridor with significantly increased train traffic.
