The Spanish Railway Accident Investigation Commission has revealed serious inconsistencies in the documentation concerning rail welds on the section where the tragic accident occurred in Adamuz. Transport Minister Óscar Puente admitted that the infrastructure manager Adif made a mistake by not immediately informing the judiciary about securing evidence materials. The investigating judge has ordered the opening and analysis of the trains' black boxes, scheduled for March 5 in Madrid.

Inconsistent Weld Data

Technical documentation concerning rail welding from May 2025 contains errors, undermining the quality of maintenance work.

Black Box Analysis

The court has set a date of March 5 for opening the train data recorders in Madrid to determine speed and system responses.

Adif's Procedural Error

The transport minister admitted that removing evidence from the accident site without the judge's consent was an unacceptable oversight.

Luggage as Cause of Deaths

Preliminary expert reports indicate that unsecured luggage inside the carriages became deadly projectiles during the accident.

The investigation into the tragic train accident in Adamuz has entered a new, crucial phase following the disclosure of controversial technical findings. CIAF has provided the Guardia Civil with information about significant inconsistencies in the documentation of welds on tracks that were renewed in May 2025. Although investigators consider the sabotage hypothesis highly unlikely, technical and procedural errors are coming to the forefront. Transport Minister Óscar Puente has come under fire after admitting that Adif removed materials from the accident site without prior notification to the court. The minister defended the institution, claiming the action was not due to bad faith but was a communication error. Simultaneously, Puente rejected suggestions of a radical change in railway safety margins, which investigative bodies might propose, deeming such steps impossible to implement in the current system. The investigating judge has already authorized the downloading and detailed analysis of data from the event data recorders (black boxes) of both trains involved in the incident. The Spanish railway network, despite a high degree of modernization, has faced problems in recent years concerning infrastructure maintenance and staffing scandals within Adif's management.The technical aspect is complemented by driver testimonies – the Guardia Civil has interviewed 19 employees who operated trains on that route on the day of the accident, yet only one reported feeling an unusual impact. An additional factor increasing the number of victims, according to investigators, was the violent movement of loose luggage inside the carriages at the moment of collision. Against the backdrop of the tragedy, a gesture of solidarity also occurred: the cities of Huelva and Adamuz announced a partnership to commemorate the victims of the disaster. Concurrently, a political dispute is unfolding over the absence of Minister María Jesús Montero from the Andalusia Day celebrations, which regional authorities assessed as a disregard for the victims and the local community. Andalusia Day, celebrated on February 28, commemorates the 1980 referendum in which residents voted for regional autonomy and is the most important local holiday.„Adif erró al no avisar inmediatamente a la Justicia del material retirado en Adamuz” (Adif erred by not immediately informing the Justice system about the material removed in Adamuz) — Óscar Puente
