A Renfe high-speed train struck a stationary Iryo train near Urda on Wednesday, killing at least 69 people. More than 100 were injured.
Why it matters: The LZB safety system failed at 8:30 a.m., shifting control of the trains to a Madrid control center. A controller then cleared the Renfe train to run at normal speed.
Where they split: The government points to one controller's decision, while unions and some opposition parties point to staffing, aging equipment and the 2021 opening of the network to private operators.
Center coverage, 5 sources: The center weighs the minister's human-error account against unions' claims of systemic failure, and tracks pressure on Puente to resign.
Left coverage, 2 sources: The left focuses on systemic failure and eroded trust, including an expert saying he would avoid high-speed trains for now.
Right coverage, 2 sources: The right focuses on the human response at the scene, including a priest who gave absolution to the injured and dying.
What’s next: Puente refused to resign and said investigators will examine the questions one by one.
