Yes Andy and what happened brings back memories of what happened in Viareggio a few years ago, in this case for gross negligence of the railways.
From what I've read, in this case, it is likely human error: the curve is where the train was derailed traveled at 80km/h when it has been covered to 190km/h, damn. The concept of High Speed relates poorly with that of security, influenced by technical faults and lack of human attention.
Real sead, too many deaths.
