Konosha - Velsk - Kotlas is the southern section of the North-Pechora railway (since 1959 as part of the Northern Railway). The main line was built according to the project of Lentransproekt (since 1951 - Lengiprotrans) to supply the country with fuel from the newly formed Vorkuta coal complex during the Great Patriotic War.
In the 1950s, the ever-increasing demand for Pechora coal required the transformation of the single-track Pechora railway into a double-track main line. The Pechora expedition of Lengiprotrans, knowing local conditions, promptly completed the design work for the Konosha - Kotlas section.
The project of the second tracks of the Pechora Mainline received an excellent assessment of the State Construction Committee of the USSR.
