Prospects and Ways of Development of Traction Rolling Stock of Railroads

Continuous improvement of locomotive fleet designs contributes to the fulfillment of the main tasks set before the railway transport industry to increase the throughput and carrying capacity of railways and reduce the cost of transportation. In this regard, the article considers the issues of developing requirements for the design and creation of new efficient and high-quality locomotive designs. The experience of locomotive construction in Kazakhstan, in the countries of the near and far abroad is presented. The main design characteristics of the operated traction rolling stock are considered. The results of a comparative assessment of the quality level of locomotives by individual and complex quality indicators are presented. Diagrams and graphs are constructed based on the results of a comparative assessment of the quality level of locomotives. The dependence of the quality level by a complex indicator on the value of the functional criterion for freight mainline diesel locomotives is determined.
