China is set to build a new high-speed railway connecting Baotou City of Inner Mongolia to Haikou City of Hainan Province, stretching a total of 2,300 kilometers. Once completed, this railway will surpass the current longest high-speed railway in the world, the Beijing-Guangzhou High-Speed Railway, which measures 2,291 kilometers. The total investment for the Baotou-Haikou High-Speed Railway is estimated to be around RMB 420 billion, with operations expected to begin by 2025.       

Most sections of the Baotou-Haikou line are designed for a maximum speed of 350 kilometers per hour, enabling travel between Baotou and Haikou in just 8 hours. Several segments of this crucial corridor, which connects northern and southern China, are already operational. Notably, the recent opening of the Chongqing-Guiyang High-Speed Railway has reduced travel time between those cities to just 3 hours.                            

Key cities along the Baotou-Haikou High-Speed Railway, including Xi'an, Guiyang, and Haikou, will experience significant improvements in transportation connectivity. Additionally, the railway will link with other major high-speed lines, such as the Xuzhou-Lanzhou and Shanghai-Kunming railways, further enhancing China's extensive high-speed railway network.
