Core Viewpoint - The development of the "Six Vertical and Six Horizontal" high-speed railway network in Jiangsu is a key focus during the 14th Five-Year Plan period, aiming for comprehensive completion by 2035, which will significantly enhance connectivity and reshape the economic landscape of the region [1][6]. Group 1: Railway Network Development - The "Six Vertical" railways include coastal, Beijing-Nanjing (Hangzhou), central, Shandong-Suzhou-Anhui-Jiangxi, Yancheng-Hangzhou, and Hefei-Xinjiang corridors, while the "Six Horizontal" railways encompass land bridge, along the river, Shanghai-Nanjing, along the Huai River, Xuzhou-Yancheng, and Shanghai-Suzhou-Zhejiang-Anhui corridors [1]. - By 2030, Jiangsu's railway operating mileage is expected to reach 5,700 kilometers, with high-speed rail accounting for 3,600 kilometers and a high-speed rail coverage rate of 87% in counties and cities [1]. Group 2: Specific Projects and Construction - The Heshun high-speed railway, connecting Suqian and Suzhou, is a crucial link in the "Two Verticals and Two Horizontals" high-speed railway main corridors, covering 59 kilometers, with 45 kilometers in Jiangsu [2]. - Seven high-speed railways, including the North Jiangsu high-speed railway and Tongsu-Jiaoyang high-speed railway, are currently under construction, totaling over 1,100 kilometers [3]. Group 3: Technological Innovations and Challenges - The construction of the North Jiangsu high-speed railway involves the Chongtai Yangtze River tunnel, utilizing intelligent tunneling technology to navigate depths of up to 89 meters underwater [3]. - Digital intelligent management is being employed to address the complex geological conditions in Jiangsu, ensuring safety and quality in construction [5]. Group 4: Economic and Social Impact - By 2025, Jiangsu's railway passenger volume is projected to reach 327 million, a 4% increase year-on-year, facilitating convenient travel and enhancing regional connectivity [6]. - The high-speed rail network is expected to drive industrial shifts from southern Jiangsu to central and northern regions, fostering cross-regional collaboration in industries such as high-end manufacturing and biomedicine [6][7]. Group 5: Regional Integration and Future Outlook - Jiangsu is working on enhancing interconnectivity with neighboring provinces, including projects like the Suzhou to Shanghai intercity railway and the Nanjing to Hangzhou second channel [7]. - The "Six Vertical and Six Horizontal" high-speed railway network is set to transform Jiangsu's spatial and temporal dynamics, promoting a more vibrant and integrated regional economy [7].
