陇海铁路
During the Second Sino-Japanese War of 1937–1945, the Republican government dismantled a number of railways to slow the Japanese advance and added 1,900 km of railways, mostly in the interior of China after coastal regions were occupied. Among the completed lines were the Longhai Railway (Lingbao-Tongguan and Xi'an-Baoji sections), Zhejiang-Jiangxi Railway (Hangzhou-Pingxiang section) and the Guangdong-Hankou Railway (Zhuzhou-Shaoguan section). The Shanxi warlord Yan Xishan built the narrow gauge Datong-Puzhou Railway across Shanxi Province. The Japanese occupiers, using forced labor, built 5,700 km of railway in Manchuria and Rehe Province and 900 km of railway in China Proper.
