The Iryo had already stopped when the signaling system failed, and the AVE behind it didn't. That rear-end hit sent carriages down an embankment, with roughly 544 passengers split between the two high speed trains in Spain. The count that follows is 64 dead and more than 100 injured. What caused it is still under investigation, and it lands as the line's second major fatal crash within the year. Service on the route is suspended. Condolences to the victims and their families.
