The mathematical modelling results of a car sorting from a hump under the influence of gravity and aerodynamic resistance of head wind are stated. These results have allowed to deduce analytical formulas for definition of car sorting speed and the traversed path on the first profile section of a hump. The results can be used for all other hump sections taking into account features of braking forces on these sections.

The estimation conditions of construction of all processes of the planned passenger train schedule of metro are considered. The concepts such as realizability conditions, realization conditions, successful realization conditions, schedule integrity are introduced. The influence of change of train pair number per hour on construction processes of the planned passenger train schedule of metro is determined.

The control system of freight transportation for the companies of operators of railway rolling stock is considered. It was developed on the basis of methods of monthly, current and daily planning of freight transportation, and also of an optimization method of operational control of private freight car parks by economic criterion.
L.N. Ivankova, S.I. Darmansky
The technique of experiment planning at research of a freight specialized station on the basis of simulated model is stated. The results of research allow to determine the optimization measures directed on work technique improvement of infrastructure objects.
Yu.O. Pazoysky, M.Yu. Savel'ev
The new mathematical model of calculation of a plan of making up mail and luggage trains is presented. It is focused on achievement of the maximum effect from used rolling stock by minimization of operating costs for transportation, and also competitive recovery.

The air buffer allowing at low material costs on commissioning to ensure reliable protection of not massive apparatus of electronic devices, and also their elements (including sensors of control systems), from the external actions in the form of vibrations in a wide spectrum of frequencies at jolts and blows under condition of insignificant values of amplitudes and movements is considered.
Three kinds of distributions (beta-distribution, DN-distribution and exponential distribution) are suggested to use as statistical models of potentially unsafe failures. The choice of each of these distributions is done on the basis of necessary truth of results and costs of computing operations on the evaluation of statistical data.
V.A. Bugreev, E.V. Novikov
Approaches to reliability evaluation of electric power systems in the market conditions are considered. The comparative analysis of two principles of reliability of electric power systems is given.
The model of power consumption by a stream of trains is described. The experimental results confirming its efficiency are resulted. The technique of a quality assessment of the passing of a stream of trains with use of the developed model is discussed. The object of the data analysis of power consumption is the detection of sections where there are not schedule delays of trains, and also the reasons of the power overexpenditure by some trains.
