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].

Core Viewpoint - The long-unused Zijin East Station in Nanjing is set to be revitalized and opened for passenger service in conjunction with the construction of the Ningxuan Railway, marking a significant development in the region's transportation infrastructure [1][2]. Group 1: Station Background - Zijin East Station has been completed since 2010 but has never served a passenger due to its proximity to other major stations and limited demand in the area [1]. - The station is part of the Xianning Liaison Line, which connects Nanjing South Station and Xianlin Station, and has been designated as one of the three auxiliary stations in Nanjing's transportation hub layout [1]. Group 2: Future Developments - The Nanjing Transportation Bureau has confirmed that Zijin East Station will be expanded and opened for passenger service as part of the Ningxuan Railway project, which is crucial for enhancing regional connectivity [2]. - The proposed expansion will increase the station's capacity from 1 platform and 2 tracks to a new configuration of 2 platforms and 4 tracks, accommodating future passenger demand and new railway connections [2]. - The Ningxuan Railway is a key vertical corridor in the Yangtze River Delta region, and its construction is expected to begin in 2026, with efforts being made to coordinate with the expansion of Nanjing Lukou Airport [2].
