Trains are built to fit it. Maintenance equipment, spare parts, and standards are all being followed based on the same dimensions. So, changing gauge is not just moving the rails. It means changing everything connected to them. And because railways last for decades, if not centuries, that decision keeps shaping the network long after the original engineers are gone.

[00:00:33]One measurement, one early design decision that impacts a railway forever.
