The authors consider the method of effective planning of the complete overhaul of railway automation and telemechanics facilities. This method is based on the application of ranking of facilities on a number of qualitative and quantitative attributes for the decrease of subjective decision-making in case of complete overhaul need.

In this article, the authors discuss the potentialities of optimization of the unified transport systems formed by several kinds of transport due to the implementation of design and construction management at the stage of formation of subsystems of each kind of transport. The improvement of the project management of the unified transport system formation is the most significant reserve of effectiveness increase of their implementation in the innovation way and allows to calculate the work schedules, budgets, the procedure of deliveries proceeding from estimates of workload and restrictions of resources and financing.

The article is devoted to the issues connected with the operation and maintenance of cars. The researches of mathematical modelling for the assessment of technological process of car unit repair were analysed. The offered approach can be applied in computer-aided design systems of the technological processes developed for machine-building enterprises.

When determining quantity and shipload of tankers - liquefied natural gas carriers for year-round transporting of gas it is necessary to consider a number of factors, such as equipment volume, gas field size, transport chart during gas production, climatic conditions. The article presents an analysis of the liquefied natural gas plant capacity.

In this paper, the influence of high-frequency vibrations in the wheel and rail system is examined, the dominant causes for their formation are described, and the research investigation of M76 rail steel structure at the operating tension levels of 700 MPa and more are given. Microstructures of the samples cut out from real rails after the action of high-frequency loading by means of optical microscopy and microhardness testing instruments were investigated.

The authors consider the realization ways of the process approach in the activity analysis of JSC "Russian Railways". The principles of detection and identification of processes, the tracking of data cross-process communications, the determining of the control actions and the resource requirement are described. The questions of the application of the "Quality Gates" process model are taken up.

The original design of the deformable buffer with the calculation of required energy capacity on the basis of mathematical modelling of its operation is suggested. The application of the proposed technical decision will allow to minimize the injury risk of passengers and maintenance personnel, as well as to reduce structural damages of the rolling stock in case of emergency collision.

The search problem of rational parameters of the dynamic system of the locomotive traction drive is considered. The search algorithm of optimum alternative of the traction drive system which allows reducing search time for a solution due to the discarding of practically unrealizable options and need a lack of search in the optimal region is offered.

The authors suggest three models of the automatic system of marshalling station operation. The first model is the simulation model of marshalling station connected to information systems and operating in online mode; the second model is directed to the storage mode of operation of the braking-up process; the third mode is the artificial neuronet implementing the adaptive operation of the station to improve its durability.

In the research, the software and knoware of the hardware monitoring and control system (as a source of primary information about the status and behaviour of an object) uses the images received in the visible and infrared ranges of wavelength is developed and implemented.
The article proposes to modify the methods of determining labour costs for information technology services for increasing the accuracy of the calculation of the human resources by means of detailed differentiation of functional tasks determined by the methodology and the introduction of individual indicators for their calculation.
The paper proposes the mechanism of the structure formation of an object (an object model) in which the procedure of recursive immersion from the inherited level of details on derivative, including the construction of the technological structure and the procedure of recursive rise from the derivative level of details for inherited. The objects for which this mechanism is constructed should have the properties of decomposition of an object into sub-objects connected by the technological structure.
