In 1918, after Finnish independence and during the Finnish Civil War, communications between Finland and Soviet Russia ceased. In spring 1918, troops under Georg Elfvengren blew up the track to prevent supplies reaching Red Guard units operating near Rautu. The railway was cut between Nuijala (67th km) and Lembolovo and 1.7 kilometers of track was removed on the Finnish side. The Leningrad – Lembolovo part became part of NKPS Soviet Railways 1919 - 1939. This section was operated by at first by Nikolai Railway and later, after name change, the October Railway.
