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.
replyThese 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?
replyI 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.
replyAccording to the article, the track had LZB, though.
replyAnd according to the article the signalling system reported, that the track is blocked.
