At least 68 people have been killed and dozens injured in a train crash between Madrid and Seville in Spain. This was reported by Qazaqyia.kz citing BBC News.
Audio recordings published in Spanish media reveal conversations between train drivers and a railway control centre in the minutes leading up to the deadly crash. Officials are investigating the cause of the disaster, which occurred when a train travelling from Madrid to Seville barrelled into a stationary train on Wednesday morning.
Three audio recordings between the control centre in Madrid and two train drivers appear to show that one high-speed train was given clearance to move even though another some 25km (15 miles) up ahead had stalled.
The release of the recordings comes as Spain begins three days of national mourning for one of the worst rail disasters in Europe's modern history.
One train, run by state-owned operator Renfe, had 397 passengers on board. Ahead of it on the same line was a train run by private operator Iryo, with 147 passengers.
A reported issue with the automatic signalling system - a computer failure - had forced all trains to halt on the affected stretch. But later the Renfe train was ordered to proceed in "error", according to Spain's transport minister.
Audio recordings published by Spanish news outlets including El Pais and RTVE reveal the conversations that took place between the two train's drivers and the control centre in the Spanish capital ahead of the crash.
In one recording, a control centre operator tells the Renfe driver to resume its journey at normal speed after some technical issues. "Continue your journey and then proceed under [Lateral Signalling Block], at normal speed with normal operation," the control centre operator says to the driver. The driver replies, "At normal speed?" To which the controller says: "Yes."
The Lateral Signaling Block is a back-up or alternative train system used when the automatic signalling or data transmission system fails.
Later, the driver of the other Iryo train says in another audio recording that communication with the train-control system has been lost and they are stationary at Urda. The train "is stationary in front of the entry signal at Urda", the driver tells the control centre operator. After a series of exchanges, the driver is then told to "resume the journey" normally.
The Iryo driver then contacts the control centre again, according to a later recording, saying they cannot start the train. "The train won't allow me to control the [security] system. That's why I am still stopped in front of the entry signal," they say. The latter recording suggests that the controller had been notified that the Iryo train remained stationary as the Renfe train approached.
Iryo said its train, which had 147 passengers on board, was "struck from behind" by another train, by Renfe train which was carrying 397 passengers.
Spain's transport minister Óscar Puente said on Wednesday that the decision to instruct the trains to move again, without any speed restrictions, was "inexplicable".
Prime Minister Pedro Sánchez said the "whole of Spain is grieving", adding that "lives have been shattered, families have been torn apart, the pain is immense".
Emergency crews worked through the night under powerful floodlights to cut open metal carriages in the search for victims, with many of those killed in the crash still to be identified.
Hundreds of personnel have been deployed to the disaster site to assist with recovery efforts, according to Spain's interior ministry, with drones and helicopters being used to find victims and remove rubble.
Witnesses described seeing people crying and bleeding, passengers trapped in their seats and smoke billowing throughout the carriages, one of which caught fire.
Sánchez said it was "unacceptable" that Spain had suffered two serious rail disasters this year, after a high-speed crash killed 46 people near Córdoba in January. It occurred on the same line as Wednesday's accident, but much further south.
Most political parties suspended campaigning for upcoming elections following the incident. The exception was the far-right party Vox. Its leader, Santiago Abascal, said his party would not take part in what he described as attempts to "use mourning to silence criticism" of the country's rail infrastructure.
