Electrokinetic performance of underground electric rolling stock of 81-740/741 type on the basis of experimental measurements are provided. The tests were carried out on Filyovskaya and Zamoskvoretskaya lines of the Moscow Metro. The received results were used for research of harmonic components of current of the train which influence on train operation systems: signals and interlocking, automatic train signalling with automatic speed regulation (ALS-ARS), both in the braking mode, and in the regenerative braking mode.

Research results allowed to develop the tool for the comparative assessment of equivalent sound volume in the cabs of various types of rolling stock and kinds of traffic received in actual operating conditions with the equivalent sound volume received in certification tests of rolling stock.
The onboard monitoring and diagnostics system of special rolling stock developed in JSC "Scientific Research and Design-Technology Institute of Rolling Stock" and used on the track maintenance machine RPB-01 is described. The structure of exchange of indices in system is presented. The particular attention is paid to the organization of the human-machine interface.

This paper considers the integration of the design antenna process in PLM for the organization of manufacturing and project management. Design approach is presented as analytical and numerical methods. An actual project developed and demonstrated that its integration to large extent reduce the time spent on the move from calculation to prototype.

In the condition of rolling stock's following curves there is the heavy wear of a wheel as a result of contact of flanges and side surfaces of rails. The comparison of a difference of radiuses of rolling circles in the case of cross motion of wheel couple is made in the article. It is shown that wheels with curvilinear profiles have great differences of radiuses of rolling circles in the case of identical movements.

Questions of simulation modeling of technical operation process of railway automatic systems are considered. The example of a simulation model of functioning of software of the microprocessor interlocking system and the example of the application of the offered model for the faultlessness assessment of software are given.
The article analyzes the substantive regulatory foundations for the strategic management of state-owned companies. The author considers the system of state relations and the company which must be confirmed by the legal and regulatory aspects at every level of strategic management.
Questions of forming of competitive advantages of the companies functioning in transport and logistic business are examined. The factors influencing the competitive status are provided and the conditions allowing to provide protection of competitive advantages are determined.

The article describes the features of the strategic management process in the companies of holding type; methodical principles of the economic-organizing analysis of the condition and development prospects of railway transport company as an object of strategic management. This article attempts revealing the features of the activity analysis of the railway company. This analysis displays in detail both the behavior of each subsystem and the local result of its activities.
Selection of requests of clients for transportations from the database of operators of rolling stock by volume not exceeding on daily work volume of restrictions from the technical plan are offered. The selected requests are distributed to shifts, and then on the three-hour periods. Selection and distribution is conducted so that first of all the most profitable requests were accepted to execution. The set of requests which is selected for the three-hour period acts as a task for intra replaceable planning of traffic flow of trains on solid route schedules by the principle "from door to door".

The authors present the necessity of introduction of the fixed schedule of train operation. The certain conditions providing a possibility of its implementation with the minimum side effects are given.
The isolation the main resources (cars, locomotives, infrastructure facilities, etc.) from overall process of operation of freight and passenger traffic leads to increase of risks of failure to provide of volume and qualities of transportations. The modeling was shown final increase in the demand for railway rolling stock and infrastructure. It is offered to reduce these risks through the integrated planning.

The process of loading with the cars is more dependent on stochastic factors. The presence of such dependence is forcing operators to stock the cars at loading. The effect of the fragmentation of the freight fleet of cars on the size of the reserve.
The analysis of public transport functioning in the megacities (by the example of Perm) is provided in the article. Dynamics and structure of main functioning activities of public transport in recent years is presented, such as: fleet of vehicles, passenger traffic volume, fare, ecological compatibility. The comparative characteristic of the activities between the cities is carried out.
