Francisco José Garzón, the 52-year-old driver of the train that derailed in Spain on Wednesday, has been formally detained by police as a government delegate confirms the train was going too fast.

When the train derailed, it was going around a bend for which the top recommended speed is 80 kilometers an hour, according to the Wall Street Journal. Government delegate Samuel Juárez said Thursday that the train was running at 220 kilometers an hour when the wreck occurred.

An American passenger said that just before the crash, the monitor screen in his car registered the locomotive’s speed at 194 kilometers an hour, the Times of India reports.

Garzón had reportedly bragged about how fast he could drive a train on Facebook.

Of the at least 78 dead, 72 have been identified as authorities continued to identify victims’ bodies on Friday, according to CNN.

Eighty-one survivors remain hospitalized. Thirty-one of these are in critical condition; of these, three are children.

Ana-Maria Cordoba of Arlington, Va., was among the dead.
