南満州鉄道
The section from Shenyang to Harbin used to be a part of the South Manchuria branch of the Chinese Eastern Railway built by the Russian Empire from 1898 to 1902. Later, the section from Changchun to Shenyang became part of the Japanese-owned South Manchuria Railway. There used to be no linking line between the Beining Railway and the South Manchuria Railway. A bridge was built for the South Manchuria Railway to cross the Beining Railway. The Huanggutun Incident took place on June 4, 1928 right at this bridge, several kilometres east of the Huanggutun railway station on the Beining Railway.
