Spanish minister refuses to resign over second major train crash on his watch

Spain’s transport minister, Oscar Puente, faces resignation demands because the crash happened under his watch and was the second mass-casualty rail accident involving the same companies this year. The January crash on the same line killed 46 people. Lawmakers across the political spectrum and rail unions have criticised Puente’s response.

Puente said a Renfe train was allowed to proceed after signalling failed, even though an Iryo train was stationary ahead. He said the controller disregarded a protocol requiring trains to travel no faster than 40 kph in those circumstances. Audio published by El Pais appeared to support that account.

Unions argue that focusing on the controller is unfair. They say the failed safety system and difficult working conditions deserve greater attention. Puente rejected resignation calls and said his duty was to establish exactly what happened, explain it clearly, and solve the problem.

The crash killed at least 69 people, according to the article. The Civil Guard also listed 64 people as missing while rescue teams worked at the scene. Authorities warned that the death toll could rise because identifying the remains was difficult and many bodies were in pieces.

The disaster was substantially worse than the January accident on the same line. That earlier crash, involving the same railway companies, killed 46 people. Wednesday’s crash therefore exceeded January’s death toll by at least 23 people. It was also described as Spain’s deadliest train accident since 2013.

The figures were not yet final. Authorities had completed 49 autopsies and formally identified five people: three women and two men. Officials said it was unclear whether everyone listed as missing was already included in the death toll. Rescue teams found no additional bodies when they overturned a carriage.

Automatic signalling is designed to stop or restrict trains when the system detects danger. In this crash, several trains were automatically stopped after the signalling system failed. That protection was then replaced by instructions from a central control centre in Madrid, creating a critical moment for human decisions.

According to Puente, the centre authorised a Renfe train to continue even though an Iryo-operated train was stationary ahead. Audio obtained by El Pais showed a controller giving permission to proceed at normal speed. Puente said the controller should instead have followed a protocol limiting movement to 40 kph.

The result was a collision near Urda in central Spain. The episode shows why a system failure can transfer responsibility from automatic equipment to people. It also explains the dispute over whether the central cause was an unsafe decision, a failed signalling system, or both. The article says investigations and explanations were still continuing.

LZB is a railway train-control system used to help manage train movements and protect trains from unsafe speeds or occupied track sections. The article does not give a full technical description, but it identifies LZB as the system that failed during the crash. Its failure mattered because automatic protection was no longer working normally.

When such protection is available, train-control equipment can monitor a train’s permitted movement and intervene if necessary. After the failure described here, several trains were automatically stopped and Madrid’s control centre took over. A protocol reportedly required any authorised movement in those circumstances to stay below 40 kph, providing a slower, more cautious backup.

That backup did not prevent the collision. Puente said the Renfe train was authorised to continue at normal speed, despite the stationary Iryo train ahead. He said this disregarded the protocol. The article also says LZB had about 170 failures annually and that its upgrade was behind schedule.

Railway workers and officials disagree because the crash involved both a failed safety system and a later human decision. Officials say a controller authorised a Renfe train to continue at normal speed, even though a protocol required speeds of no more than 40 kph after the signalling failure. That account puts emphasis on the control-centre decision.

Controllers and their unions stress what happened before that decision. Several trains had been automatically stopped when the signalling system failed, and the central control centre then had to manage movements. Union leader Raquel Ayllon said workers operated under difficult conditions and that attention was moving too quickly toward human error.

The dispute matters because assigning blame affects accountability and safety improvements. Puente said he had never used the phrase “human error,” though he did not rule it out. He also said staffing at the Madrid centre had nearly doubled since 2012. The article leaves the final cause unresolved.

ERTMS stands for the European Rail Traffic Management System. The article describes it as a newer standard developed with European rail association UNIFE and says it has been installed across most of Spain’s high-speed rail network. It is intended to modernise train-control arrangements and strengthen how trains are supervised.

The Madrid-Seville line still relied on LZB when Wednesday’s crash occurred. That system failed, and the planned ERTMS replacement had not yet begun operating there. Thales España won a 2021 contract to install ERTMS by early 2026, but the work fell behind and passed to Hitachi Rail in 2024. Puente said installation was complex because the line had to remain open.

Puente now expects ERTMS on the line to begin working in early 2027. Replacing older equipment could reduce reliance on emergency manual control, but the article does not claim it would eliminate every risk. The delay has intensified questions about safety and maintenance after two crashes.

Railways use several protections because every layer can fail or be misunderstood. Automatic signalling may stop trains, but equipment can malfunction. Speed limits reduce the danger during degraded operations. Operating protocols give controllers and drivers clear instructions, while human checks can catch mistakes or unusual conditions.

The crash illustrates the need for those layers to reinforce one another. The signalling failure automatically stopped several trains, but control then shifted to Madrid. A protocol reportedly required movement at no more than 40 kph. Instead, a Renfe train was authorised to continue at normal speed toward a stationary Iryo train, according to Puente.

The article does not present a final safety finding, but the consequences are clear. At least 69 people died, and unions say the failed system should receive more attention than individual blame. The delayed ERTMS upgrade also shows why reliable equipment, clear procedures, and effective oversight must operate together over time.
