Nobody questioned this. Nobody ever questions the announcements. Red became the first replacement. It rolled confidently into Blue's territory, claiming efficiency. Blue divided itself into triangles to accommodate the intrusion—this is what cooperation looks like when geometry replaces trains. Orange tried to be the liaison wheel, the one that would make everything mesh smoothly. But Purple interrupted with its own circular logic, and soon there were wheels within wheels, each claiming to be the original service, each insisting the delays were actually punctuality viewed from a different angle.
