The mathematical model, proposed by the authors, is based on a concept of asynchronous machine in a form of two infinitely long cylindrical shells with current layers, the shells being separated by an air circular gap. The study is based on comprehensive use of information relating to the operation mode, when axes of stator and rotor coincide. New parameters are introduced, resulting from radial displacement of a rotating rotor, but their formulation allows using known methods of calculating parameters of machines.

The article considers the influence of the form of laws of distribution of single observations on quantile of statistics used for statistical hypotheses testing and having chi-square distribution of or Fisher distribution with the normal distribution of individual observations. Through mathematical modeling on the example of four options it is shown that difference of the distribution law as compared to normal law results in a significant change in the value of quantiles. This is equivalent to an unjustified change in the level of significance in the choice of a decision rule.

Logistical approaches to organization of passenger transportation in Russia have taken practical shape quite recently. Basic terms of passenger logistics continue to be formed and still are interpreted differently. To ensure effective work in this area it is necessary to formulate common concepts and describe distinctive features of transportation, organized on the basis of logistic principles. The article deals with concepts such as territorial mobility of population, mobility of passengers, logistics of passenger transportation, logistic chain of passenger movement, passenger transport system, multi-modal transportation in passenger traffic, intermodal transportation in passenger traffic.

The author examines approaches to improvement of the efficiency of trucks’ operations on the basis of a concept of transition of a road carrier from pure physical movement of cargo to the system of transport and logistics services. The author proposes methods for structuring transport and logistics processes and suggests trends and directions of organization of their interaction.

The authors participated in MIIT University’s researches aimed at refining mathematical and computer models of cars were refined, describing a motion along railway lines with normalized irregularities in plan and profile. The models consider spatial oscillations of each node, details of solid body, structure, material properties, as well as predict abrasive wear of critical parts and components of a bogie. The article justifies a possibility to increase overhaul life of a car by a simple upgrade of a bogie model 18-100 from 160 to 250 thousand km, and by a comprehensive modernization – up to 500 thousand km.

The article presents the results of measurements of fluctuations of metal and reinforced concrete superstructures of railway bridges in the passage of the rolling stock with different speeds. The obtained data can be used to refine models of structures and to develop algorithms for damage detection.

The authors introduce the results of measurements and analysis of mechanical vibrations of track superstructure with intermediate rail fastening types Pendrol and ZHBR65-SH regarding vibrodynamic impact of rolling stock. Full-scale experimental studies have been performed on the main section of the enlarged Ekibastuz rail track section. The data obtained can be used as a criterion for justifying selection of the most optimal type of rail fastening.

The rationalization of recovery modes of thread surface profile of wheel sets due to the use of a criterion «optimal cutting temperature», introduced by professor A. D. Makarov is shown. The work of a tool in this mode provides its maximum dimensional stability (durability) and required speed of metal processing. This process involves similarity method, thermophysical and thermomechanical approaches, as well as a method of linear programming. It was experimentally found that using similarity method, it is possible to calculate processing modes, which not only improve the features of a cutting tool and provide satisfactory chip formation, but also extend service life of wheels of metr o cars.

Application of non-contact soft regulation for electric train requires control of traction drive taking into account the restrictions on longitudinal dynamics, i. e. the intensity of increase in traction of train’s acceleration when it starts moving. This task is solved in a control system using a master element that implements restrictions on the intensity of acceleration growth. A block diagram is shown that provides the implementation of this criterion on digital elements.

The article reveals the essence of multiplier effect and time multiplier. An example of calculation of time multiplier is provided with the example of travel by car along 10 km route in the metropolitan city. A comparative analysis of characteristics of time multiplier and traditional, macroeconomic multiplier is given. It is emphasized that considerable values and high volatility of time multiplier can be seen as an evidence of unfavorable situation in the transportation system, and attempts of «smoothing» serve as criteria of improvement of this situation.

The analysis of global and Russian experience of concession agreements in the transport sector shows the high dependence of successful projects on efficient allocation of demand risk between a grantor and a project company. The article describes major factors affecting demand risk distribution regarding Russian road concessions, contains conclusions and assumptions of the author on current and future trends related to the studied components of concession projects, particularly on the transition from the projects with real tolling to availability fees.

The author conducted a research to determine the effectiveness criterion of TRS regarding repair, modernization or replacement. Criterion, based on the dimension theory, enables us to find maximum operation efficiency of traction means in real economic conditions.

Russia turns its gaze increasingly towards Asia and, in particular, aims to find new opportunities in China, which concordant foreign policy is aimed at coupling of potential of Eurasian Economic Union and ambitious project «Silk Road Economic Belt». It is not just a revival of traditional trade routes, but a real infrastructure revolution. Ways of implementing promising potential include also creation of railway lines and trans-shipment centers on the route Shanghai–Sabetta–Kyzyl–Shanghai using the Northern Sea Route and the multimodal port Sabetta in Yamal.

Located in the center of the Eurasian continent, being an important link of a transcontinental bridge between Asia and Europe, and having a sufficient transit capacity Kazakhstan continues to take efforts to implement it while organizing freight delivery from China to Russia and Europe. In terms of transit potential of the country, the transit volume is not high enough today. This is due to the fact that available transport and logistics infrastructure cannot to full extent serve and meet the country’s logistical needs for the total transit volume. Hence, there is an urgency of solving the tasks aimed at development of transport and logistics infrastructure, in particular at formation of a rational interaction system between all modes of transport, at development of systems of transport and logistics centers, representing key components of quality enhancement of transport complex of the republic as a whole. The article considers existing approaches as well as strategic projects with regard to solution of above problems.

In operation freight car axle box is subject to considerable dynamic forces that determine its relatively low durability and, as a consequence, a rapid transition to a latent state of emergency. The method for constructing a probabilistic model of axle box reliability allows to determine a moment of axle box transition in the state of failure and to prevent the emergence of a number of negative consequences for cars being on the line: derailment, train accidents, unproductive idle hours of cars, etc. The article found out that distribution law used by the author when checking the axle box life length to failure does not contradict experimental data and performed calculations.

The authors present an analysis of reliability of axle boxes. Provided data characterize its level in relation to the total freight car fleet. The estimation of parameters of failure flow due to damage to roller axle boxes in cars of total fleet compared with universal covered car fleet is given. The question arises on causes of failures and possibility of having a mathematical model that could help in determining the reliability degree of axle boxes.

This study was conducted with the objective of determining the possible applicability of Glasser’s theory of choice (needs satisfaction) on prediction of personnel’s organizational loyalty. This study was implemented based on descriptive-correlative method and on the survey that engaged 2899 male personnel of Islamic Republic of Iran Railways, residing in Tehran, using simple cluster random sampling and organizational loyalty questionnaire and needs intensity assessment test. Regression analysis and multivariate analysis of variance were used for data analysis. According to the results, a significant relationship exists between Glasser’s theory of needs satisfaction and organizational loyalty of railway personnel (p<0.001). The author shows what needs are most significant for prediction of organizational loyalty and suggests recommendations regarding perspective work with the staff.
