The article presents the estimation method of the reliability and durability indicators of traction rolling stock parts and the reliability data collecting and processing system of the traction rolling stock in operation. Data obtained from "KTZ-Freight transportation" JSC were used for calculations.

The article examines the centralized train operation algorithm of urban railways of a modern megalopolis. This algorithm takes into account the dependence of control restrictions on the system state with the disturbance prediction. The analysis of disturbance prediction errors in the stochastic and deterministic disturbance models is carried out.

To correctly determine the survivability of rolling stock parts during fatigue tests, it is necessary to accurately determine the moment when the fatigue crack begins to develop. This article is devoted to the acoustic emission method for detecting fatigue cracks at the initial stage of their development. Frequency, time and median filters are applied. The method has been approved in testing the side frames of wheeled bogies of freight cars.

The article deals with the problem-solution related to the estimation of stresses arising in the cylindrical shell of a tank under forced oscillations taking into account the inertia of the liquid cargo. The calculation was performed using the dependencies of semi-momentless shell theory in double trigonometric sequences.

The authors consider the specific elements of the voltage regulation system and the main aspects of their functioning when the current changes in the range from active-inductive to active-capacitive nature.
I.P. Knyshev, T.T. Tulemisov
The article is devoted to the possibility of using intelligent video surveillance systems to provide remote control of technological operations. The general structure of the technical vision system is given. The operation features of the technical vision system are considered.

The article studies the special generating polynomials forming polynomial codes with the good indicators of detecting characteristics for the construction of functional control systems of combinational logic circuits. The conditions for the complete detection of symmetric and asymmetric errors in information vectors when using the investigated polynomials to construct a noise-proof code are revealed. The experimental researches with control combinational logic circuits from the LGSynth`89 set using special generating polynomials were conducted.

The author proposes to organize the marshalling station operation using the philosophical law of unity and the struggle of opposites. To support the competition between stations, the "operation management" optimization problem is proposed. The mathematical formulation of this problem and its solution algorithm are given.

The authors consider the existing approaches to the development of the occupational risk assessment methods in JSC "Russian Railways". The article presents the operating assessment method of occupational risks for employees of railway car management production sections. This method makes possible to increase the efficiency and validity of decision-making by middle managers on ensuring ensure safe conditions and identify priority areas of activity in the field of labour safety.

The article presents an approximate mathematical analysis of the internal structure of the atmospheric boundary layer and redeveloping of some meteorological variable profiles for operational meteorological information (according to the real aero-sensing of the atmosphere and weather prognostic maps) to the anthropogenic substances inflow forecast.
A.A. Basalaeva
The article presents the results of a questionnaire survey aimed at studying the attitude of contact network electricians and electricians to labour safety and key conditions of the production process in the power supply division. Based on the obtained data, the author has drawn some proposals aimed at improving the labour safety management system in the power supply division, the professional selection system of electricians, and the improvement of the employer and employee interaction in the modern conditions.
