Lianyungang–Zhenjiang high-speed railway is a high-speed rail line in Jiangsu province connecting the port city of Lianyungang with the river city of Zhenjiang. The line links coastal nodes such as Haizhou District, Donghai County, and inland hubs including Xuzhou, Suqian, Huai'an, and Yangzhou. It forms part of regional corridors integrated with national networks like the Beijing–Shanghai high-speed railway and the Nanjing–Qidong railway.
The route begins at Lianyungang near the Yellow Sea coast, passes through Donghai County, skirts the western periphery of Xuzhou, continues through Suqian and Huai'an, crosses near Yangzhou before terminating at Zhenjiang on the southern bank of the Yangtze River. It intersects with major lines including the Longhai railway, the Beijing–Shangqiu railway, the Nanjing–Xi'an railway, and the Shanghai–Nanjing intercity railway, providing transfer links to nodes such as Beijing South railway station, Shanghai Hongqiao railway station, Nanjing South railway station, and Xuzhou East railway station. The alignment includes river crossings proximal to the Grand Canal and passes within commuting distance of urban districts like Ganyu District and Jiangdu District.
Initial proposals arose during regional planning sessions involving National Development and Reform Commission and Ministry of Transport officials coordinating with Jiangsu Provincial Government and municipal authorities from Lianyungang, Xuzhou, Suqian, Huai'an, Yangzhou, and Zhenjiang. Feasibility studies referenced corridors in national plans alongside projects such as the Northeast–Southwest Transport Channel and provincial strategies influenced by leaders from Chinese Communist Party committees and governors of Jiangsu. Environmental assessments engaged agencies like the Ministry of Ecology and Environment with input from research institutions including China Academy of Railway Sciences and universities like Nanjing University and Southeast University. Funding frameworks combined capital from China Railway bonds, local fiscal contributions from county governments, and loans arranged with state-owned banks such as the China Development Bank and the Industrial and Commercial Bank of China.
Construction contracts were awarded to large contractors including China Railway Group Limited and China Railway Construction Corporation. Engineering works involved complex structures: viaducts over the Grand Canal, bridges near the Yangtze River, and tunnels adjacent to urban cores in Xuzhou. Key suppliers included CSR Corporation Limited and CRRC for track components and signalling subcontracted to firms with experience on projects like the Hangzhou Bay Bridge and the Hong Kong–Zhuhai–Macau Bridge. Standards followed national technical codes used on lines such as the Beijing–Shanghai high-speed railway, with electrification installed to 25 kV AC and signalling compatible with Chinese Railway Technical Standards. Construction milestones were overseen by municipal engineering bureaus in Lianyungang, Xuzhou Municipal Government, Suqian Municipal Government, and Zhenjiang Municipal Government.
Stations range from major interchanges at Xuzhou East and Zhenjiang to local stops in Donghai County and Sihong County. Design teams included architects who had previously worked on Nanjing South railway station and Shanghai Hongqiao railway station, incorporating passenger facilities for transfers to China Railway High-speed (CRH) services and intercity buses tied to hubs like Lianyungang Port Passenger Transport Center. Stations provide ticketing linked to the 12306 China Railway system and intermodal connections with regional metros such as the Nanjing Metro and bus networks serving districts such as Haizhou District.
Operations are managed by China Railway Shanghai Group which schedules services integrated with nationwide timetables coordinated at Beijing Railway Bureau. Typical services include D- and G-class trains running at designed speeds up to 250 km/h, timed for connections to long-distance services to Beijing, Shanghai, Guangzhou, and Xi'an. Peak timetables increase frequency to support commuter flows between Xuzhou and Suqian and holiday spikes tied to Chinese New Year and the National Day Golden Week. Ticketing uses national price bands and dynamic allocation systems in coordination with stations like Lianyungang railway station and Zhenjiang railway station.
Rolling stock operating on the line comprises CRH and later-generation units produced by CRRC including models analogous to the CRH380 series and the CR400 family where compatible. Trains are configured for 250 km/h operation with 25 kV AC overhead lines, continuous welded rails, and slab track sections in urban areas similar to installations on the Beijing–Tianjin intercity railway. Signalling employs European Train Control System-derived technologies adapted by China Academy of Railway Sciences with automatic train protection and centralized traffic control integrated into operations centers modeled after those on the Shanghai–Kunming railway.
The line accelerated connectivity for ports such as Lianyungang Port with inland logistics hubs in Xuzhou and Zhenjiang, improving freight intermodal transfers at junctions linked to the Longhai railway and the Beijing–Shanghai high-speed railway. It stimulated urban development projects in municipalities including Suqian and Huai'an, attracted investment from state-owned enterprises and private investors including firms listed on the Shanghai Stock Exchange and Shenzhen Stock Exchange, and supported tourism growth to cultural sites like Slender West Lake in Yangzhou and heritage areas in Xuzhou. Social impacts involved labor mobility between counties such as Sihong County and cities like Nantong and Suzhou, contributing to provincial strategic goals articulated by the Jiangsu Provincial Government.
