Briefing
In the serious collision on the high-speed line Madrid–Seville between Los Yébenes and Urda (province of Toledo) on 28 October 2026, prosecutors and technical experts are focusing on two facts: the failure of the Linienzugbeeinflussung (LZB) over a stretch of around 63 kilometres and the instruction issued shortly afterwards by the control centre of Adif, allowing trains to resume running. According to the Ministry of Transport, the Linienzugbeeinflussung system failed at around 08:30 following a communication fault affecting several control computers; several trains then stopped automatically.
About six minutes after the system failed, at 08:36, the Adif control centre instructed trains to resume running “at normal speed”, according to the audio recordings released. The drivers of the affected Iryotrain reported that the safety system could not be reinitialised and that they were standing in front of a signal. While the Iryo did not set off again, according to the available records, an AVE by Renfe resumed its journey and collided with the stationary train at around 08:53.
Investigators are now examining whether the required procedures for operating with faulty safety equipment—including proceeding on sight at a significantly reduced speed and additional safeguards—were followed. Technical investigations are also looking into why the Linienzugbeeinflussung system failed and whether there were faults in the communication chain between the computers.
Official bodies, including Renfe, Iryo and Adif, are cooperating with the investigations and have activated emergency protocols. So far, only preliminary accounts based on ministry statements, company information and analysed radio recordings are available; final expert reports and an official final report are still pending. While the findings remain incomplete, key questions are still unanswered: the precise cause of the safety-system failure, the decision-making process at the Adif control centre and possible breaches of operating rules.
