The Guangdong-Hong Kong-Macao Greater Bay Area will implement 13 intercity railway projects with a total mileage of about 775 kilometers, as well as five integrated transport hub projects, with a planned total investment of 474.1 billion yuan. The newly approved railway construction plan will build a multi-level railway network with high-speed railways, general-speed railways and suburban railways in the Greater Bay Area, to form a transportation circle with one-hour access between major cities in the Greater Bay Area, two-hour access between major cities and inland cities in Guangdong Province, and three-hour access between major cities and neighboring provincial capitals, thus creating a “Greater Bay Area on a track”.
