Since the 1950s, Lengiprotrans has been developing a project for the West Karelian line, now part of the Oktyabrskaya railway. The transport development of the Karelian Autonomous Soviet Socialist Republic was necessary for the export of timber materials that were used to restore the national economy in the post-war years. The road was also of military-strategic importance, since it ran along the state border.
In 1956, by interpreting aerial photographs, the position of the Sukkozero - Yushkozero - Lendery route was chosen. Two expeditions of the institute carried out surveys and issued documentation for the construction of a railway line. The route was laid in difficult geological conditions: through granite hills, swamps, swamps and lowlands.
The line was built and commissioned in 1961.
