The train in question is a Frecciarossa 1000 https://en.wikipedia.org/wiki/Frecciarossa_1000
The Italians designed it but won't run it at more than 300km/h in Italy citing local infrastructure concerns. I guess that leaves other countries to find the edge cases. I'll be interested to find out how fast it was going during the crash.
Looks like a Frecciarossa 1000 derailed in 2020 but it was due to a manufacturer defect in a track switch replaced the night before.
The defect was not caught by the manufacturer or the system operator. It was due to two crossed wires in an assembly.
I know a lot more engineering goes into these trains due to the higher stakes. Japan’s high speed rail hasn’t had a fatal accident in 60 years. I’m wondering what the cause of this will turn out to be.
AnsaldoBreda did also manufacture the Fyra trains for the short-lived high-speed trains here in The Netherlands. After three trains lost parts in the first month, it was banned from operations. https://en.wikipedia.org/wiki/Fyra
