As the country mourns, Francisco José Garzón, the driver of the Alvia train which derailed in Galicia killing 78 people, has been arrested by police and charged with negligence and crimes related to the accident.
The driver remains in hospital and has not made an official statement to either the police or the court, although this could happen at any time. The decision to carry out the arrest was made by the police and not at the request of the judge investigating the incident.
Francisco José Garzón has already admitted that the train was travelling at 190 kph in an urban area restricted to 80 kph.
The two black boxes from the train are in the possession of the judicial police but these are not being opened until authorisation is received from the court which, at the current time, is busy with other tasks.
The high-speed train is equipped with the advanced safety system ERTMS which is designed to automatically prevent risk, but the system is not installed on the section of the track where the incident occurred as it is considered an urban area. Instead, a digital system called ASFA is in operation which warns of potential risks but cannot do anything preventative to resolve issues, like slowing a train.
