A train traveling from one region could not navigate the rails of another without manual transshipment of every single crate. When standard track gauges were finally adopted, they unlocked unprecedented physical commerce but simultaneously introduced a systemic vulnerability. A single obstacle placed on a shared rail could now derail transport networks across an entire continent, turning our greatest economic efficiency into a
