The increase in heavy freight traffic in recent years is fueled by an increase in demand for coal as an alternative energy resource of oil, and also steel, in the manufacture of which large quantities of iron ore are required. However, in the former Soviet Union, the use of heavy freight trains was complicated due to insufficient quality of the railway. In this regard, the article considers the features of construction truck wagons of models 12-9941 produced by LLP "Kazakhstan car-building company" according to the project of Qiqihar railway company (PRC). The laboratory testing of rolling stock conducted in Dnipropetrovsk national University of railway transport has identified the main dynamic characteristics that meet the requirements of the international standard. The use of gondola wagons of model 12-9941 in the organization of the heavy traffic creates tensions in the construction of the permanent way, which do not exceed the permissible limits in both straight and curve track sections.
