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].

Group 1: High-Speed Rail Construction Progress - The construction of the new railway project through Shuyang has been included in the national planning, addressing the long-standing public concern about high-speed rail access in the region [2][3] - The Jiangsu Provincial Railway Office is working with local governments and relevant departments to advocate for the inclusion of the new railway in the "14th Five-Year" railway development plan [2] - The feasibility study and preliminary design for the Hefei to Shuqian section of the railway are progressing, with hopes for project approval by the end of this year or early next year, aiming for construction to start soon after [3] Group 2: Fire Safety Risks in Service Areas - There are reported fire safety risks in multiple service areas along the Ninghang Expressway, including issues such as insufficient staffing and unlicensed personnel in fire control rooms [4] - The Jiangsu Provincial Transportation Comprehensive Law Enforcement Bureau acknowledged the need for improved oversight and compliance with fire safety regulations in service areas [4] - Plans are in place to conduct on-site inspections and analyses to ensure the safety and operational integrity of these service areas [4][5]
