The Hefei–Nanjing railway also known as the Hening railway (simplified Chinese: 合宁铁路; traditional Chinese: 合寧鐵路; pinyin: Hé-Níng Tiělù) is a railway line in China, running from Hefei to Nanjing at 250 km/h (155 mph).

[1] The line is 166 km (103 mi) long and began service on April 18, 2008.

[2] High-speed trains on the line reduced travel time between Nanjing and Hefei from over three hours to 1.5 hours.

The Hening Line forms part of the higher-speed Shanghai–Wuhan–Chengdu passenger-dedicated railway from Shanghai to Chengdu and the easternmost section of the Nanjing–Xi'an Railway.

The faster Shanghai–Chongqing–Chengdu high-speed railway is under construction, including the parallel Shanghai–Suzhou–Huzhou high-speed railway (completed in 2024)[3] and the Hefei South–Huzhou section of the Shangqiu–Hangzhou high-speed railway (completed in 2020).
