AT 19.45 on January 18, the rear three cars of Iryo train 6189 travelling from Málaga to Madrid derailed near the small village of Adamuz, northeast of Córdoba on the Madrid – Seville high-speed line. Seconds later, a Renfe Alvia service bound for Huelva struck the derailed coaches head-on, leaving 46 dead and more than a hundred injured.

On March 5 the data recorders recovered from the trains involved were opened at the headquarters of the Railway Accident Investigation Commission (CIAF) in Madrid. Investigators, who published an interim report on January 23 suggesting that a track fault, possibly a failed weld, might be responsible, said it would take at least a week to extract and analyse the data before any conclusions are formed.

But it is not only railway systems under scrutiny. In the months following the accident, the actions of those bodies responsible for rail infrastructure, track, maintenance, and the management of evidence have also come under scrutiny.

According to a report submitted by the CIAF, inconsistencies have emerged in a technical document relating to rail welding undertaken at the site of the accident. The report was originally completed on June 25 2025 but was modified three days later. Changes were made to several sections of the document. Two different versions were subsequently submitted by engineering consultancy Ayesa: one dated June 25 2025 and another dated February 1 2026 - after the accident had occurred.

An explanatory note dated February 3 2026 fails to reflect the earlier modifications recorded on June 28 2025. Investigators say this creates what they describe as an “inconsistency between the two versions,” making it impossible to determine precisely which sections of the report were altered and when. A second explanatory note, also sent after the accident, appears to contradict the first, further complicating attempts to identify which version contains accurate information.

CIAF has also raised concerns about other technical records connected to the works prepared by contractor Maquisaba. Investigators noted that numerous signatures on these records appear neither to be handwritten nor digitally authenticated, but instead consist of scanned images, a format that is easily manipulated.

State-owned infrastructure manager Adif has rejected any suggestion of document manipulation. Sources within the company told Spanish newspaper El País that Adif simply delivered the documents requested by investigators “intact” and insisted that it is cooperating fully with the CIAF investigation, pointing instead to Ayesa as the firm responsible for the reports. The documentation had previously been reviewed by Redalsa on behalf of the consortium undertaking track renewals at Adamuz, comprising Ferrovial, FCC, OHLA and Azvi, before being examined again by Ayesa.

Further controversy surrounds the handling of physical evidence from the crash site. In a report sent to the court, Spain’s national police force stated that Adif personnel removed material from the accident site during the early hours of January 22–23, several days before a judge granted access. According to investigators, an Adif employee admitted that, following verbal instructions from a superior, he moved welding equipment and other materials to Adif’s maintenance base at Hornachuelos.

Adif has argued that the removal was carried out to prevent deterioration of the materials. However, after receiving the police report, the judge overseeing the case ordered the company to return the items immediately, warning that the unauthorised removal of evidence could carry potential criminal liability.

Symbol of modernisation

For decades, Spain has invested heavily in high-speed rail. Just months before the accident, in May 2025, the Ministry of Transport and Sustainable Mobility hosted a European showcase highlighting a network of more than 4000km, second only in length to China, built at construction costs significantly below international averages. During its peak expansion years, the government allocated around 0.6% of annual GDP to rail infrastructure, nearly double the European average. Spain’s high-speed trains and infrastructure became symbols of modernisation, territorial cohesion and engineering prowess.

Yet expansion has not been without trade-offs. Much of the investment focused on building new high-speed lines, while the conventional network and long-term maintenance budgets received comparatively less attention. Sections of Spain’s high-speed network have recently been operating at near-capacity, after market opening introduced competition between incumbent Renfe and its rivals Ouigo and Iryo, the former a subsidiary of French National Railways (SNCF) and the latter having Italian State Railways (FS) subsidiary Trenitalia as its majority shareholder with a 51% stake. Increased service frequencies driven by lower fares and heavier traffic inevitably placed greater stress on the infrastructure.

However, the apparently catastrophic failure of a rail weld following track renewals on the Madrid – Seville high-speed line has fuelled public doubt and raised questions about whether the system’s rapid expansion has outpaced its maintenance capability.

For a country that has long promoted its high-speed model abroad as efficient, safe and technologically advanced, the reputational stakes extend well beyond the accident’s immediate technical causes.

“Poor handling of a crisis will intensify the damage,” notes crisis-management expert W Timothy Coombs, associate professor at Eastern Illinois University in the United States. He adds that reputational harm often leads to “greater scrutiny by regulators, pressure from stakeholders, and financial ramifications.”

For transport systems that depend on public confidence, the severity of reputational damage will depend heavily on how the public interprets the causes of the crisis.

“When a crisis is linked to failures by the organisation, maintenance or oversight failures, the situation is much worse,” Coombs says. Such failures “inflict much greater reputational damage and can trigger moral outrage.” That outrage emerges when stakeholders believe risks were known but insufficiently addressed.

“Moral outrage makes people less forgiving,” Coombs adds, making reputational recovery significantly more difficult.

Other academics who have studied crisis management emphasise that reputational crises rarely depend on a single factor. As Arjen Boin of Leiden University in the Netherlands explains, public reaction is shaped by a combination of circumstances surrounding the event itself.

“On the one hand, it depends on the characteristics of the incident, the number of deaths, its visibility, the time of year, whether children are involved, the factors that dramatise an event,” Boin says. “These shape how much attention it receives from the public, the media and the political agenda. Negative attention can then translate into a reputational crisis.” Once an event becomes a national or international news story, the institutions responsible inevitably become part of the narrative.

Another key variable is what Boin describes as the organisation’s trust reservoir. “If an organisation already has many incidents behind it, another one will reflect badly,” he explains. “But if it is considered very safe, that changes how the event is interpreted.” In other words, the reputational consequences of a disaster depend partly on the reputation that existed beforehand.

The aftermath of disasters is rarely determined by the technical facts alone. “An incident is bounded in time, but the reputational impact depends on how the organisation responds and how the story is framed,” Boin says. Different parties will seek to frame the event according to their own perspective: the media or victims might portray an organisation as negligent, while that organisation will attempt to present its own interpretation in order to preserve its reputation.

In cases like Adamuz, where several public bodies and private contractors are involved, the investigation can resemble an institutional “whodunnit,” with each party seeking to protect its credibility as scrutiny intensifies. “In many cases it becomes a competition between the differing perspectives,” Boin says.

The challenges ahead for the Spanish rail industry and its political supporters will be to demonstrate transparency and accountability while effectively implementing any necessary structural reform. These are tangible actions that can reassure both the Spanish travelling public and international observers that lessons have been learned and future risks mitigated.
