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 bridge crossing over the Varda River was developed as part of the design of the Karpogory-Vendinga railway line, which is part of the Belkomur meridional highway. The road should ensure the transportation of natural and mineral resources from the regions of the European North of the Russian Federation.
The length of the structure is 124 m.
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 bridge crossing over the Vashka River was developed within the framework of the design of the Karpogory - Vendinga railway line, which is part of the Belkomur meridional highway. The road should ensure the transportation of natural and mineral resources from the regions of the European North of the Russian Federation.
The structure is projected on 412 km of the line, 3 km from the Vending station.
Bridge length - 270 m, layout - 3x88 m.
In the 1990s, the construction of the bridge supports began.
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.
In the 1950s, Lengiprotrans conducted a major expedition to select the direction of the railway line in the Ob-Irtysh basin. The road was supposed to facilitate the development of forests in the North of Western Siberia.
To select the direction of the route, aerial photography at a scale of 1: 30,000 was widely used. On-site office photogrammetric processing of images, production of contact prints and reproductions was carried out. Topographic work on the binding of aerial photography was carried out by 4 survey parties.
Locomotive depot Petrozavodsk (TCh-24) is located in the capital of the Republic of Karelia and is part of the Oktyabrskaya railway. It was founded back in 1916.
In 1959, a massive replacement of steam locomotives with diesel locomotives began on the Kirov railway. In this regard, in the late 1950s - early 1960s, Lengiprotrans developed a project for the reconstruction of the depot with a conversion to a heating system.
In 1962, the first repair of the locomotive was carried out at the locomotive depot in Petrozavodsk.
Station Tver (in 1931–1998 — station Kalinin) is a large transport hub of the Oktyabrskaya railway. The historic station was built in the middle of the 19th century. Since the 1970s, Lengiprotrans has been developing a project for a new station complex for 2,000 passengers.
In 1991, a new station was opened, located on the other side of the railway, opposite the old building.
