The calls between Atocha and the train drivers before the Urda crash, explained phrase by phrase

The audio recordings of communications between the control center and train operators before the Urda accident reveal uncertainty and technical jargon. The AVE train operator reported a transmission failure, indicating the track ahead was occupied. Despite this, the control center instructed the operator to proceed at normal speed, which was a critical error. The recordings show discussions about disconnecting the safety system and the confusion surrounding the correct procedures. Ultimately, the operator was given a code that allowed for reconnection after the issue was resolved, but the conditions for safe operation were not clearly defined, leading to the tragic incident.
