On Friday, the European Public Prosecutor’s Office (EPPO) announced a second investigation into suspected fraud involving EU funds for the Madrid‑Seville high‑speed railway line in Spain. The probe, launched by the EPPO’s Madrid office, focuses on possible misuse of money allocated to the maintenance and upgrading of the line, which includes safety, signalling and communication systems.
The investigation will involve a review of the activities of ADIF, the Spanish Railway Infrastructure Manager, the Spanish Railway Safety Agency (AESF), and the Court of Auditors. It is being carried out with the support of the Central Operative Unit (UCO) of the Spanish Civil Guard. The EPPO says the probe is an initiative of its own and has been approved because of the high level of public interest. No further details will be released at this stage.
In a statement, the EPPO confirmed that the investigation concerns EU funds allocated to the upgrading of the Madrid‑Seville high‑speed line.
"The investigation concerns EU funds allocated to the upgrading of the Madrid‑Seville high‑speed railway line, including its safety, signalling and communication systems,"an EPPO spokesperson said, according to Xinhua.
This tense period follows a deadly train crash near Urda in the province of Toledo on October 28, the same line that is under scrutiny. The incident raised concerns about safety standards and the management of European Union financing on the project. The earlier accident in January, at Adamuz, which killed 46 people when a train failed to stop, previously prompted the EPPO to launch a first probe into alleged fraud in March 2026. That investigation examined potential misuse of maintenance funds on the same line.
Spanish officials have yet to respond to the EPPO’s announcement. The Court of Auditors, one of the key bodies under examination, is tasked with ensuring the lawful use of public funds, including those from the EU. The addition of the Civil Guard’s UCO to the investigative team signals a focus on potential criminal wrongdoing.
In addition to the EPPO’s statements, another report from the BSS news network claims that the train crash “killed 69 people” on a Spanish rail line that had been renovated with EU funds. The BSS note casts doubt on the casualty figures given by Xinhua and raises questions about the safety record of the upgraded infrastructure. The discrepancy between the 46 deaths reported by Xinhua for the Adamuz crash and the 69 deaths cited by BSS remains an open question for investigators.
EU prosecutors have been appointed to oversee investigations when fraud involving EU funds is suspected, in accordance with the EU’s common framework for cross‑border prosecutions. The EPPO’s second investigation is part of that framework, aiming to hold parties accountable who are alleged to have embezzled money from the European Union’s cohesion and transport programmes.
The timing of the investigation comes as Spain’s government and the EU are scrutinizing the safety of the high‑speed rail network, which has been expanded rapidly over the past decade. Questions remain about how the €X billion in EU funds earmarked for this project were spent, whether procurement procedures were properly followed, and if the upgrades improved safety as intended.
Throughout the unfolding investigation, the EPPO has committed to transparency and the protection of public funds. The agency’s decision to keep certain details undisclosed indicates that sensitive matters—potentially involving confidential evidence or ongoing investigative techniques—are still in progress. Analysts predict that the investigation could lead to reforms in procurement and monitoring of EU funds in Spain’s railway sector.
As the investigation proceeds, stakeholders will watch closely for updates from the EPPO, ADIF, AESF, and the Court of Auditors. Both the international community and the Spanish public continue to demand accountability, while the EU closely monitors how the findings could affect future funding and safety protocols for high‑speed rail projects across Europe.
