Audio reveals exchanges between control centre and drivers before deadly Spain train crash
The recordings appear to show one high-speed train was given clearance to move even though another up ahead had stalled.
Audio recordings published in Spanish media reveal conversations between train drivers and a railway control centre in the minutes leading up to a deadly train crash that killed at least 69 people and injured dozens.
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.
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".
