Intercity railways in the GuangdongHong KongMacao Greater Bay Area (GBA) face operational challenges when used for public transit. These challenges include unclear functional specialization, misalignment with urban development plans, and insufficient network operation, leading to low service efficiency. This study proposes a reorganization strategy informed by successful regional rail transit practices globally. The strategy focuses on three key areas: (1) Reorganizing intercity railways, urban express lines, and other rail lines based on distinct functional levels for optimized service allocation. (2) Optimizing the network layout based on urban travel demand characteristics. This includes optimizing external corridors, strengthening fast and direct connections within the core area, and further strengthening urban rail interconnection through station wiring and connecting lines. (3) Optimizing intercity station and transfer services to improve passenger experience. Implementing these strategies is expected to provide valuable insights for improving operational service levels and promoting the sustainable development of intercity railways in the GBA.
