The Inta - Pechora - Rybnitsa railway line is part of the Northern Railway. Lengiprotrans has developed a project of the second tracks on this section to increase the capacity on the instructions of the Ministry of Railways.
The road is intended for the export of natural resources from the Vorkuta and Pechersk coal basins to the central part of Russia. The line is characterized by empty passenger traffic, since unloading exceeds loading: most of the trains go in the direction of the South, and the flows back to the North are insignificant.
The railway line Ruchi Karelskie - Alakurti (now Alakurtti) is a section of the Oktyabrskaya railway, passing through the territory of the Kola Peninsula. At the station Ruchyi Karelskie the line branches off from the Loukhi - Kandalaksha direction towards the border with Finland.
The Ingol - Latvian railway line is a section of the Kemerovo railway (since 1997 it became part of the West Siberian railway).
The road solved the problem of connecting the Kansko-Achinsky and Kuznetsk coal basins (KATEK and Kuzbass) to the railway network, in particular, access to the Trans-Siberian and Central Siberian lines. During this period, the government of the USSR adopted Resolutions to increase coal production, but the existing railways from Siberia to the center of the country could not provide the required freight traffic.
The Karpogory - Vendinga railway line is a part of the Belkomur (White Sea - Komi - Ural) meridian highway in the direction of Arkhangelsk - Syktyvkar - Solikamsk.
The Karpogory - Vendinga section should connect two dead-end lines and turn the Mikun - Arkhangelsk direction into a transit highway. This will directly link the two resource-rich regions and shorten the train route from the Komi Republic to Arkhangelsk by almost 400 km.
The Ilyinsk — Krasnogorsk — Uglegorsk railway line is a projected section on the territory of South Sakhalin and is part of the Far Eastern Railway (Far Eastern Railway) system. The route should solve the problem of coal transportation.
Back in 1937, the Tomari — Ilyinsk line was built, but World War II prevented its continuation north to Uglegorsk.
The Narva - Tapa - Tallinn railway line runs through the Republic of Estonia. The line is part of the Baltic Railway, built in 1870. In the 1980s, Lengiprotrans PJSC developed a project for the construction of second tracks on the Narva - Tallinn section.
Strengthening the line was due to the fact that it was an important link in the USSR railway network and connected the Tallinn industrial region and the seaport of Muuga with other republics.
In the post-war years, Lentransproekt (since 1951 - Lengiprotrans) worked on the project of the Chum - Salekhard - Igarka Transpolar Mainline. The road was designed in special secrecy with the strategic goal of defending the Arctic coast of the USSR. In 1953, work was suspended with the death of I.V. Stalin, who supervised the construction.
In the postwar years, Lengiprotrans developed a project for the Salekhard - Nadym - Igarka railway line, now known as the Transpolar Mainline. The road was conceived as a backup for the Northern Sea Route to connect the Soviet Arctic with the country's railway network. In 1953, construction was suspended. In the 1970s, the institute resumed work on certain sections of the highway.

The Volkhovstroy - Koshta railway line runs in the North-West of Russia through the Leningrad and Vologda regions. Volkhovstroy and Koshta stations are located near the regional centers of St. Petersburg and Cherepovets, respectively. The line is part of the Petersburg-Vologda railway, built in 1902-1905. The exit of trains from St. Petersburg to the Trans-Siberian Railway is carried out through this route.
