Train traffic resumed on Friday on the tracks parallel to where at least 80 people died when a train derailed just outside the northwestern Spanish city of Santiago de Compostela.
The regional government said 95 people were still in hospital, 32 of them, including four children, in serious condition.
Medical experts were still trying to identify 13 of the bodies early on Friday, leaving distraught families to wait for definitive news.
Relatives and friends of unidentified victims continued to arrive at the local morgue.
The driver of the train was under police guard in hospital after the accident, which an official source said was caused by excessive speed.
