The driver at the centre of last week's Spanish rail disaster was speaking on the telephone at the moment his train derailed, data from the "black box" recorders has shown.
Francisco Jose Garzon Amo, 52, who faces multiple charges of negligent homicide over the crash, was talking on the telephone to an official at Renfe, the state-owned railway operator, according to a statement released by a court in northern Spain.
He had received a call from controllers on his work mobile and was being given instructions on what route to take to his final destination.
He may also have been consulting a map at the time, according to the court in Santiago de Compostela.
"Minutes before the train came off the tracks he received a call on his work phone to get indications on the route he had to take to get to Ferrol," the statement said. "From the content of the conversation and background noise it seems that the driver consulted a map or paper document."
