[SystemSafety] Spanish train crash

[Peter Bernard Ladkin]

Very sad stuff, disturbing.

The first part of this article shows the derailment as it happened

It seems odd to me, but I am not a specialist rail investigator.

It sort of looks like Alstom kit, but I had thought the Spanish multiple-unit HSTs were Siemens (I've not actually been in Spain to see).

Given the lengths of those trains, one can estimate the geometry of the curve and see the bank angle of track. It doesn't obviously look to me like something that cannot be taken at 190kph. Does it look more obvious to the specialists here?

Isn't there a continuous-linear-control system on those trains (and what looks to be new track) that enforces speed control?
