As the first morning maglev glides from Shanghai's Longyang Road Station toward Hangzhou at 430 km/h, it carries more than passengers—it symbolizes the complete reinvention of urban geography. The Shanghai Metropolitan Area, encompassing nine cities across three provinces, has become what the World Bank calls "the most functionally integrated urban network on earth."
