“Train operator SNCF’s chief executive, Jean-Pierre Farandou, said the attackers had started fires in “conduits carrying multiple (fibre-optic) cables” that carried “safety information for drivers” or control the motors for points.”

Secure your stuff
If it is critical it should be air gapped with only authorized personnel able to connected things to it
How would that help when someone sets your wires on fire?
They needed physical access
