Spain is in mourning over the deaths of 78 people in a high-speed train crash on Wednesday.
More than 90 passengers out of 218 on board the train that crashed outside Santiago de Compostela remain in hospital, including some 30 critical.
The injured train driver has been detained and faces charges of "recklessness", police say.
There are reports that the train was travelling at more than double the speed limit at the time of the crash.
Spain has declared three days of national mourning over the crash - one of its worst ever rail disasters.
On Friday, police said 78 people had been confirmed dead - down from 80 announced earlier.
They said the difference arose because human remains had been wrongly identified in the initial stages.
At least 130 people were taken to hospital after the accident, and 95 are still being treated.
