南滿洲鐵道
After Russia's loss of the southernmost section of this branch as a result of the Russo-Japanese War, the Kuancheng station (Kuanchengtze, in contemporary spelling) became the last Russian station on this branch. The next station to the south - the new "Japanese" Changchun station, just a short distance to the south - became the first station of the South Manchuria Railway, which now owned all the tracks running farther south, to Lüshun. A special Russo-Japanese agreement of 1907 provided that Russian gauge tracks would continue from the "Russian" Kuancheng Station to the "Japanese" Changchun Station, and vice versa, tracks on the "gauge adapted by the South Manchuria Railway" (which happened to be the standard gauge) would continue from the Changchun Station to the Kuancheng Station.
