During the Russian Civil War and the foreign military intervention the employees of the Far Eastern Railway had to rebuild destroyed bridges and damaged tracks and ensure stable traffic of urgent loads. Rail line restoration began in the winter of 1924-1925 from the reconstruction of the Khabarovsk Bridge due to the importance of resuming a through traffic over the Trans-Siberian Railway. In 1929, they built the Nadezhdinskaya-Tavrichanka line for the needs of the Primorsky Krai (for the servicing of agricultural regions near the Khanka Lake, in particular). In 1931, they finished the construction of the Sibirtsevo-Turiy Rog line. In 1935–1936, they reconstructed the Uglovaya-Partizansk line due to the increasing extraction of coking coal from the Suchansky coalfields. In 1940, they commissioned the Volochayevka-Komsomolsk-on-Amur line and Sibirtsevo-Varfolomeyevka line. In 1941, they finished the construction of the Birobidzhan-Leninsk line and Partizansk-Nakhodka section and commissioned the Smolyaninovo-Dunai, Partizansk-Sergeyevka, and Baranovsky-Gvozdevo lines. In 1940, they finished the construction of the main eastward sorting station called Khabarovsk-2 with a fully mechanized hump yard.
