Collision of two high-speed trains near Toledo: How could this happen — and what needs to change?

Answer

How do European rail safety rules handle interoperability when several operators run on the same tracks, and what can go wrong here?

European rail safety relies on interoperable systems like dispatching, automatic protection, and digital traffic management across operators. When several operators share tracks, gaps can appear if interfaces aren’t tightly regulated or fully integrated. Clear regulation and robust testing are essential to prevent problems from becoming accidents.
