[SystemSafety] Spanish train crash

[Ignacio González (Eliop)]

Peter:
These trains are special units able to use HS tracks (European standard)
and also Iberian tracks (which are wider). In this particular case, they
are from Talgo. The line is a HS track with different ERTMS levels; most of
them are L2 or L1, but some of them are "only" ASFA, where the braking
process is only supervised in discrete points. It appears that this section
was ASFA, with a speed limit of 80 km/h.
A friend of a friend of mine was in the train. She is in the hospital, but
at least he is alive.
