The current control system dates from the early 90s. They started rolling a modern system with more redundancies and automatic blocking in 2022 but it's still not fully deployed.

PZB is from 1934. Arguably always prioritizing deploying the most modern system on the highest profile lines, is what prevents us from properly rolling out the basic safety systems everywhere.

PZB is only used up to 160 kph, and relies on wayside signals being read by operators. That's not possible on a high speed line. A more sophisticated signal system is simply necessary here.

These high speed trains are pretty recent. Are we really not upgrading safety systems past the 1930's when upgrading a line from ~80kmph to ~300kmph?

I was only talking about the general problem domain, not about this specific location. The current safety system is also not was has caused this, likely. Or rather it has caused this by it's availability, not by it's safety.

According to the article, the track had LZB, though.

And according to the article the signalling system reported, that the track is blocked.

I'm pretty sure we had modern computer systems around 1990.
