Spanish Transport Minister Blames Train Crash That Killed 68 on ‘Inexplicable’ Error

Spanish authorities are investigating the cause behind a high-speed train collision Wednesday morning that killed at least 68 people and injured dozens of others. The country’s transport minister suggested that a combination of “inexplicable” human error and a computer failure was likely behind the tragedy, which occurred near Urda, Toledo, more than 80 miles south of Madrid.

Transport Minister Óscar Puente said in a press conference that the state-operated Renfe train slamming into the rear of a stationary private train operated by Iryo was due to an “inexplicable” order from a command center for Spain’s trains. Puente said the center had a computer malfunction before the order.

“It was the control center, through its operators, that made the decision to resume traffic, under circumstances that, from our point of view, are inexplicable,” Puente said. He added later: “Clearly, it was a wrong decision.”

Puente said that they have identified the person who decided to let the Renfe train continue moving even though the Iryo one had already stopped, but he has not spoken to the control center operator. “This person is subject to whatever the investigation determines,” Puente said in the press conference.

The regional government of Castilla La Mancha, where the Toledo town is, said in a social media post that 53 people are still receiving medical treatment in healthcare facilities. The number of people hospitalized reached 107 earlier in the day.

Renfe said train services between Madrid, Ciudad Real, and Andalusia have been suspended.

The Wednesday collision is now the deadliest train crash in the country since a 2013 incident in Santiago de Compostela that killed 80 people. But the latest collision follows a similarly deadly train crash in January, which involved high-speed trains operated by the same two companies. In that crash, which occurred in Adamuz, Córdoba, 46 people died and 122 sustained injuries. 

Prime Minister Pedro Sánchez, who visited the crash site, announced that his government would declare three days of mourning in response and vowed an investigation. “What is unacceptable for a country like Spain is to suffer two high-speed rail accidents in the same year,” Sánchez said, though he noted that it “is highly likely that the two accidents are unrelated.”

Despite the accident, Puente insisted that the Spanish rail system is “safe and comparable to that of other countries in our region.” However, while there are “very clear” regulations and protocols in place, he admitted, “failures can obviously occur.”

What happened?

The crashes involved a Renfe high-speed train bound for Seville with 393 people on board, and an Iryo train carrying 151 passengers. The Renfe train departed Madrid at 8:00 a.m. local time, while the Iryo train left a little earlier at 7:54 a.m., plying the same route.

Spain’s rail infrastructure uses the German LZB (Linienzugbeeinflussung) system, a railway safety technology that monitors train speeds and sends traffic instructions to the driver’s cab. Operations are meant to revert to manual control when the automated safety system fails.

Puente, in the press conference, said that at around 8:30 a.m., three computers on the railway network experienced a communication failure, taking the LZB control system offline along a 63 km (39 mi) stretch of the track. This automatically stopped about six trains traveling on that section, Puente said. The central command center would assume manual management of rail traffic.

By 8:36 a.m., the command center authorized the Renfe train to continue its journey “normally,” even though Puente says internal protocols dictate otherwise and that a “red signal” should have prevented the journey from resuming. The Renfe train had 25 km (15.5 mi) to travel before it struck the Iryo train, roughly 17 minutes later, at 8:53 a.m. The speed it reached before the impact is still unknown, but it could reach up to 200 km/h (124 mph) for that stretch of track.
