The Nanchang–Jiujiang intercity railway (simplified Chinese: 昌九城际铁路; traditional Chinese: 昌九城際鐵路; pinyin: Chāng-Jiǔ chéngjì tiělù) is an intercity high-speed railway operated by China Railway Nanchang Group, connecting Nanchang (the provincial capital) and Jiujiang, in Jiangxi Province, China. It is the first newly constructed high-speed railway in Jiangxi Province.
At Jiujiang, the railway connects with the Wuhan–Jiujiang Passenger Railway, opened in 2017, providing a continuous high-speed line between Nanchang and Wuhan.
Nanchang–Jiujiang high-speed railway: runs roughly parallel to this railway but will have a higher maximum speed, 350 kilometres (220 mi), and will end at Lushan railway station in Chaisang District rather than Jiujiang railway station in Lianxi District.
