The Guangzhou East Ring Intercity (Panyu–Baiyun Airport North) and the Palian Intercity Railway have opened, connecting with four existing lines to form a 400-km network across six Greater Bay Area cities. Built by China Railway Construction Corporation (CRCC), the projects overcame dense urban zones and mixed geology using advanced tunneling, AI-based monitoring, and BIM technology—marking a major step toward a fully integrated regional rail system.
