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.
On the Ingol - Latvian line, the institute carried out geological surveys and made a technical project. However, the construction was not implemented due to the reorientation to the construction of the Baikal-Amur Mainline.
