In order to solve the pre-marshalling problem in container yard, a mathematical programming model and a multi-stage genetic algorithm with binary encoding scheme are required. In the proposed algorithm, the objective function is designed via the definition of confuse coefficient; several heuristic operators provide development of necessary methodical and operational actions. The way how to achieve better solutions is shown at the example of two researches, confirming the efficiency of genetic algorithm with binary encoding as an optimizer to construct a container pre-marshalling model.

A method of providing the quality of surface of assembly parts made of non-ferrous metals and their alloys is developed. A scheme of unit is determined, providing the necessary conditions of machining, designed for combination of mechanical and anode impact on the workpiece surface. Complex technology allows to achieve a set of qualitative characteristics and widely vary parameters in the operations of both turning and milling.

In addressing the issue of energy saving in transport there is a dilemma: either to increase speed of motion (delivery), and to reduce time when the goods are in the process of product distribution, or to reduce power intensity of transport services. The article analyzes the use of a measuring instrument of transport work - «tran».
Calculations are provided, proving its inadequacy to evaluate energy consumption, especially in the presence of logistics systems and the established order of supply chains service. In the context of logistics neither tonne-kilometres, nor «tran» are critical, as in the background of maximum possible reduction of total cost of product distribution, rather synchronization of operations to ensure continuity and effective technical support (including power intensity) of the transport process becomes determining.

The authors offer design of transverse connection assembly in the bogie of type 18-100 of a cargo car. The aim is to eliminate lozenging of side frames, reduce intensity of sinuous movement, vibration load and wear of parts and assemblies, improve smoothness, as well as eliminate pendular oscillations of side frames with respect to their own longitudinal axes (thus facilitating also the operation mode of bearing units and cast bearing elements). Modernization of a bogie by mounting transverse connection assembly, as well as replacing axle bearings with cassette-type bearings and adapters of MIIT design with wear-resistant vibration absorbers, assumes to substantially increase guaranteed overhaul life of freight cars.

The article considers issues of track laying in extreme climatic conditions of Trans-Baikal region, features of heavy trains and new locomotives of Ermak type operations atZabaikalskaya railway [Trans-Baikal branch of JSC Russian Railways]. The interrelation of key indicators for the construction of continuously welded rail track (CWR) is set. They include stress-free temperature, annual temperature amplitude, critical radius and speed of traffic. Technical solutions are suggested that provide electric locomotives with necessary dynamic, speed and other performance characteristics, as can allow well as reduction of the cost of laying and maintenance of CWR.

The paper continues research aimed at increasing interference immunity of railway service radio communication. Previously proposed method of clipping referred to single-sideband voice signal with frequency modulation (hereinafter - FM). Now the article refers to double-sideband signal with a balanced modulation (hereinafter - BM). The same gain in fighting interference is proved. Correlation technique allows evaluating harmonic distortion at clipping BM signal. Such an assessment has not existed yet. Analytically, it is shown that application of the method is equally effective for single-sideband and double-sideband voice signals: interference immunity grows by 4,33 times, the level of harmonic distortions is the same (7,4%).

Transportation market links closely economic and transportation processes. Consumer demand dictates the conditions, but it also stimulates carriers to improve organization of production and logistic support of goods movement on railways. In particular, this concerns loading / unloading of cars - with greater dependence on stochastic factors. The presence of such dependence leads to non-productive costs, economic losses. The article shows how to optimize distribution of traffic volumes, helping minimizing costs and maximizing revenue growth in the framework of interaction of operating companies and cargo owners.

Ideas of discounterism, in researchers' opinion, have emerged as a response to market's «glut», excess of supply over demand. And to some extent the elements of discount technology have been used by carriers of goods and passengers for over half a century. The authors correlate the scientific understanding of market relations with myths (four of them are reviewed) and prejudices about companies-discounters, give their opinion on their practices and pricing policies, economic assumptions of the existence of this phenomenon in the transport business.

Appropriate calculations are made, evaluation criteria of network performance and their elements are justified, as well as delay coefficient of network equipment. The results of experimental verification showed that obtained calculated values of the quality of network services for different types of information meet the requirements of ITU-T G.1010 recommendations.

When building a simulation model of the railway station or the junction one of its mandatory elements is duration of shunting operations. With the help of AnyLogic modeling system to assess this position it is necessary to consider the accounting method for acceleration and deceleration of shunting train in half-run. Moreover, the method used must comply with the rules of calculation adopted in the AnyLogic, requirements of existing procedures for regulation of shunting operations (taking into account emerging constraints). The article describes a way to solve this problem, satisfying these requirements. At the same time adjustment of some of the inaccuracies contained in the current method is proposed.

Problems with mounting of electric locomotive traction motors threaten railway safety. The authors analyze the nature of destruction of fastening bolts and brackets, and formulate a number of working hypotheses explaining causes of destruction. The theoretical significance of the article is to examine the conformity of a design scheme used to determine forces acting on elements of the supporting structure, with actual reactions occurring in the bearings. Particular attention is paid to possible emergence of periodic disturbances in traction drive from clutch taking into account gyroscopic moments, occurring when it is rotating. On the basis of dynamic calculations conclusions are suggested about the causes of destruction of mounts and about what scheme of traction motor fastening to the bogieframe is rational, especially for high-speed modes.

The workenglobes voluminous subject. The author describes organization methods to achieve comprehensive state of Russian society. Modern conflicts are revealed as a result of incompetence of management systems focused on technocratic approach, while humanitarian approaches are mostly ignored. A suggested model supposes introduction of civilitarian order that includes social justice, reasonable sufficiency, equal weightiness. The author argues thatcivilism together with railway development can renew the role of a human for the well-being of the country.

The article deals with geopolitical theories of K. Haushofer and H. Mackinder and place of railways in them, with a number of railway projects of the Second World War in Europe and Asia, the role of rail routes in the plans of belligerents, logistic support of front-line operations, as well as in the Allied victory over the powers of the «axis». The author draws a conclusion on railway transport mission in terms of geopolitics, state strategy and military logistics.

From the Cimmerians to the present day - in the range of times and epochs the author appreciates the emergence of the idea of building a bridge across the Kerch Strait and its implementation in the real world of geopolitics and historical events over the years. Central place in the analysis is occupied by the period of the Great Patriotic War. The experience gained at that time, the comparison of appeared design alternatives (including already at a later time) allow to judge optimistically about the beginning of work on a new project of the bridge.
