How exactly did your brain turn "cable that runs along the train track" into a "neuralgic facility"? Your seem to think this a problem of uncontrolled physical access, when it is about redundancy and why cutting so few cables can create a service outage in large parts of north-western germany. Did you know that, by cutting just a few cables, overland lines that are easily accessible, large parts of the USA would have electricity blackouts? That we would need cameras and fences and motion detectors and security checkpoints along thousands of kilometers of cables to secure physical access? Even if we bury them instead of running them overland? As if digging is hard. The problem is not about access to some facility, it is about a lack of redundancy in what should be a network.
