Following a January 18 train collision in Adamuz, Spain, involving Iryo and Alvia trains, authorities have expanded their investigation into the causes of the accident, which resulted in 46 fatalities and over 100 injuries.

Initial inquiries by the Guardia Civil focused on the condition of tracks, rails, and welds. Investigators have since broadened their scope to examine the “real state” of all railway material at the site, including sleepers and ballast. 

In recent developments, a judge from the Montoro Court has summoned technicians from Iryo and Renfe, alongside judicial experts, to assist in the decryption and interpretation of black box data. This process, scheduled for November 12, follows the opening of the black boxes and the extraction of data from security cameras located inside the Iryo train.
