Abstract
Purpose: The priority direction of strategic programs for the development of railway transport is the design and introduction into operation of new rolling stock, which is characterized by high technical and economic indicators. In this regard, the goal is to formulate scientifically based technical solutions to reduce the costs of production, maintenance and repair of traction rolling stock and improve its traction and energy characteristics. Methods: To achieve the stated goal, the following methods have been applied: structural analysis; statistical processing of large arrays of experimental data; computer simulation; theory of locomotive traction. Results: Priority directions for improving traction rolling stock have been identified. A set of scientifically based technical solutions has been developed to improve the traction and energy characteristics of selfcontained locomotives, which may allow the transition to a single platform for diesel and electric locomotives. As a result, the reduction in costs for the production, maintenance and repair of traction rolling stock and an improvement in the traction and energy characteristics of locomotives will be achieved. Practical significance: Economic effect obtained due to reducing the costs of production, maintenance and repair of traction rolling stock and the consumption of fuel and energy resources for train traction.
