This route is the last of the Spanish high speed lines that still has an older train protection system. There has been a similar accident in 2002 in Germany where LZB was also used: https://de.wikipedia.org/wiki/Linienf%C3%B6rmige_Zugbeeinflu... . Now after 24 years you might think they had mitigating procedures in place...
The railroads in the USA were trying to push back and delay improvements to automated safety systems until the 2015 Amtrak 188 crash https://youtu.be/-mzaavmtT9M
Only was finally fully rolled out in I think 2020 5 years after the accident.
Delaying/avoiding spending money on safety seems to be common around the world.
2006 subway accident in Valencia had a similar context, they used the FAP system, cheaper than ATP, which would have prevented the accident.
