The authors consider the main approaches to the training of the operational personnel involved in traffic control of urban rail transport systems. The article describes the methods of assessment of knowledge and skills in traffic operation and the occurrence of emergencies. The structure of the integrated automated system for training and knowledge assessment of operational personnel of urban rail transport systems is proposed.

To decide the feasibility of using outsourcing technologies and a life cycle contract for the production process of technical operation of railway automation and telemechanic systems, the authors propose a method to assess the localization level of production of railway automation systems at the operating facility of the railway line. The localization level is calculated based on the life cycle cost of these systems.

The article focuses on the problem of creating methods of searching for new patentable designs of locomotive traction drives. The previously proposed classification of traction drives does not meet the tasks, therefore, an additional level of grouping by integration degree was added to the new classification.

The article reveals the problem of correct constructing of computing methods of railway stations. The authors introduce a new principle of correctness - the coincidence of the functional role of the calculation element in reality and the model. For a station, the functional role is the structural support of the process operation. And the paper considers the existing computing methods of yards and yards necks. The ways of their improvement are proposed.
