Overview
- The pericial session convened at the Tribunal of Montoro on Thursday, November 12, 2026, with judicial experts and technicians from Iryo, Renfe, Hitachi and Hasler Rail present to access, decode and interpret the trains' recorders.
- Hasler Rail, owner of the Multirec‑SG and Husler‑SG visualization tools, was ordered to assist on site and to submit a descriptive technical report of the actions taken and results obtained.
- Other company technicians and court‑appointed peritos must produce interpretative reports that assess each train's overall behaviour, correlate subsystems and identify possible causes or contributing factors.
- Certified copies of the raw data were extracted at the CIAF facility in Madrid on March 5 with Policía Judicial present, and those copies remain in police custody as the court works from the dumped files.
- Specialists have ten days after the session to deliver their reports to the judge and those technical findings will feed the criminal inquiry and any civil proceedings while families await answers about the January 18 crash that killed 46 people and injured over 120.
