Aerial footage shows the aftermath of a deadly high-speed train collision in Toledo, Spain, on Wednesday, 28 October.
At least 68 people were killed and 77 people were injured in the country’s second major rail crash this year.
Police are questioning staff at a control centre.
The cause of the collision, which involved a Renfe and an Iryo high-speed train, has not been confirmed.
