The Xinyi–Changxing railway or Xinchang railway (simplified Chinese: 新长铁路; traditional Chinese: 新長鐵路; pinyin: Xīn–Cháng tiělù), also known as the Xinchang line (simplified Chinese: 新长线; traditional Chinese: 新長線; pinyin: Xīncháng xiàn), is a single-track railway line in eastern China between the cities of Xinyi in Jiangsu Province and Changxing County in Zhejiang Province.

It runs north-south through the entire length of Jiangsu Province and the northern tip of Zhejiang.

Major cities along route include Huai'an, Yancheng, Hai'an, Jingjiang, Jiangyin and Yixing.

Construction began in September 1998 and the entire line was completed in April 2005.

At its peak, a pair of ferries made 48 trips per day across the river.
