Spain train driver on phone at time of crash, police say

The driver of the train that derailed in Spain last week, killing 79 people, was on the phone at the time of the crash, investigators said Tuesday.

Data from the train's "black box" also indicates driver Francisco Jose Garzon was going 95 mph, almost twice the speed limit, when the train veered off the tracks, hit a wall and caught fire just outside the city of Santiago de Compostela last Wednesday night.'

According to a Spanish court, Garzon was talking on the phone to an official with the Renfe national rail company at the time as well and looking at a paper document.
