That's one of the nice parts of the 'Proven in use' method. It also includes those common cause failures that can't be calculated.

Indeed let's move back to the pre-accident topic(s). I agree that at this stage everything worth writing about it has been written...

Well, to restart with common life, let´s not move away from the Madrid-Galicia HSL, but let´s move closer to Madrid, to the point between the Olmedo junction and the future Medina del Campo HSL station where they´ve started to install the sleepers:

The single-track railway you see parallel to the HSL in construction is the old Segovia to Medina del Campo line, closed in 1990, except for this section that was left in use to connect the HSL to Medina del Campo and allow Madrid-Santiago-Corunna/Vigo-Pontevedra Talgo and Alvia trains running on the HSL:

This is a scheme of the area (between Olmedo junction and Zamora), the dashed red line is the Madrid-Galicia HSL.
As you can see, it will include a by-pass to allow direct Galicia-Valladolid-Basque Country trains, and also a spur to the Salamanca line.
Don´t mind the blue line to Salamanca, it won´t be built. Only the dashed red and dashed blue lines will:

Madrid-Galicia HSL.
This is the sector between Zamora and Pedralba de la Pradería (or Lubián, according to the map above), a bit closer to Galicia.
Works on the viaduct over the Ricobayo reservoir (on the river Esla):

Thanks for the update. Those small black vertical lines on the red doted line are just lot boundaries, right? Are all those conventional railways shown on the scheme above in operation and expected to remain once the route to Zamora is finished in a year or two?

Yes, but the one just below Medina del Campo is where the Medina HSL station should be built.

Not started as I understand from your sentence. I didn't know anything about the place outside the railway discussions so I checked wikipedia and looks like it's a fairly small town (pop. 21,000) in the middle of farming area. Is it really worth building a station there, particularly a fair distance from the town centre?

More news:

HSL Alicante-Murcia.

We´re all rather angry at the regional Murcia government here in SSC Spain, since they´ve chosen a very bad option for the Murcia HSL station.
We believe that they haven´t realised that the planned pre-crisis underground station won´t be built.
So they´ve chosen to have the station at Los Dolores, outside the city.
The city of Murcia has a population of 440,000 people. Surreal.

The most logical option was the third rail and an upgrade of the current Murcia-El Carmen station.

We´ll see how this case evolves.

I´m particularly angry at the choices made for the whole Alicante-Murcia-Lorca HSL project.

I´m not sure. Those backing the construction of the station say that the people from Valladolid travelling to Galicia will use it, but as Valladolid will have its own Bilbao/Hendaye-Valladolid-Ourense-Corunna/Vigo trains, I´m not so sure.

We´ll see how the case evolves, too.

The Medina HSL station is far not only from the town center, but also from the old Madrid-Medina-Valladolid railway, making a common station between the HSL and the old line impossible, thus not allowing Valaldolid-Galicia trips changing trains in Medina.

The Medina HSL station should have been built on the junction between the two lines...

If the system is well co-ordinated passengers from Valladolid can change to Galicia HS line just as easily in Segovia. It's probably a minor market, but if I'm wrong on that then it's also possible to build 3-4 km of extra track allowing trains coming from Valladolid and further north to join Galica line directly.

I think you are right.
I´ve never understood why Adif has never favoured stations that combine HSR and classic rail (stations like Valence-TGV, Massy-TGV, Besançon-Franche Comté-TGV, or in the future Avignon-TGV or Belfort-Montbéliard-TGV).

Do you mean to build extra track from the classic line, or extra HSL?

If it´s the second, it´s planned.

Good news: the EPSF (Établissement Public de Securité Ferroviaire) has authorized the class 100 AVE trains to run on the Perpignan-Figueres HSL and on classic French lines under 1.5 kV.

Spain won't be in crisis forever. It is best to adopt this solution and not kill beforehand the undeground project, something that would happen if they did as you suggest.

I have to declare that I do not know the project but in all cases, as near to city centre, so many passengers.
