ИСТИНА

The Vorkuta railroad is experiencing continuous deformation due to permafrost thaw settlement. The railroad was built in early 1940’s. Today the railroad is loaded to only 30 % of its capacity to serve coal and passenger traffic. The low traffic capacity is caused by continuing deformation of the railroad tracks, which are relevelled each year. The railroad connects Vorkuta, Labytnangy and Bovanenkovo with the European part of Russia. If the railroad extends to Sabetta port on Yamal peninsula, the railroad capacity must be increased up to 100 % of its capacity to satisfy growing traffic demand. Thus, continuing deformation of the railroad tracks must be fixed. Many sections of the studied railroad have deformed due to permafrost thawing and differential settlement.
