Nanjing–Tongling railway or Ningtong railway (simplified Chinese: 宁铜铁路; traditional Chinese: 寧銅鐵路; pinyin: níngtóng tiělù), is a single-track railroad in eastern China between Nanjing in Jiangsu Province and Tongling in Anhui Province. The line is 208 km (129 mi) long. Major towns along route include Nanjing, Maanshan, Wuhu and Tongling.
The line follows the southern bank of the Yangtze River from Nanjing to Tongling. The eastern third of the line was built in 1935 as the Nanjing–Wuhu railway and the western two-thirds from Wuhu to Tongling was completed in 1968. In 2010, a second track was proposed for the Nanjing to Wuhu section.
However, according to the latest news, this railway will remain single track but will be improved to add the railway electrification system which will be better for the cargo train to carry more goods but not the average speed in this line.
As of the late 2012, published schedules show that the railway has been extended along the southern bank of the Yangtze beyond Tongling all the way to Jiujiang in Jiangxi Province, allowing direct service from Nanjing to Nanchang and points south and west.
Now it is also possible to travel from Shanghai to Chongqing, the capital of R.O.C. between 1937-1945, by train via Shanghai–Nanjing railway, Nanjing–Wuhu–Tongling railway, Tongling–Jiujiang railway, Jiujiang–Wuhan railway, Wuhan–Yichang railway, and Yichang–Chongqing railway. This railway group become the most important Yangzi River railway system which is along the bank of Yangzi River and across middle part of China from eastern to western parts.
