What happens on trains in France, Germany, or Italy when technology on the tracks fails?

The article discusses how different countries manage train operations when signaling technology fails. In France, trains are halted while the system is restored, using traditional phone communication for safety. Germany has clear protocols for degraded operations, allowing trains to proceed at reduced speeds. Italy adopts a Mediterranean approach, quickly resuming operations with speed limitations. Switzerland aims for a unified European standard, while Norway has modernized its signaling system. China employs a multi-level backup system that allows continued operation at reduced speeds during failures.
