The line is about -long, with about in Jiangsu Province and about in Anhui Province. The design speed is . It is jointly funded by China Railway, Jiangsu Province and Anhui Province. It is considered an important measure to promote the integration of the Yangtze River Delta. Among them, Nanjing City invested RMB ¥249.2 million in the project. Project construction started on 20 September 2019 and is expected to be completed in 2026.
Route The Nanjing–Huai'an intercity railway connects to Huai'an East station in the north and originates from Huanglou line station of the Lianyungang–Zhenjiang high-speed railway. It runs along the west side of Beijing-Shanghai Expressway and then roughly along the Subei Irrigation Main Canal through Madian, Linji, Fanji, Zhuba in Hongze District, Dailou in Jinhu County, and Tianchang district of Tianchang, Anhui province, and then roughly along the course of the to the Liuhe district of Nanjing. Six stations are to be built: Huai'an East, Hongze, Jinhu, Tianchang, Liuhe West and Nanjing North. It crosses the river through the Shangyuanmen tunnel and connects to Nanjing station, connecting with the Shanghai–Nanjing intercity railway.
This intercity line was also one of the options considered for the Beijing−Shanghai high-speed railway Second Channel currently in the planning stage. Unlike other candidate lines, this line, like the Beijing-Shanghai railway, passes through Nanjing and Anhui Province.
