The article deals measures to improve the efficiency of using empty cars on the example of the East Siberian railway. The problem of the mechanism for managing cargo and empty runs has been identified. It is necessary to create the system for managing empty rolling stock. The authors consider the technology of working with the company's empty car fleet and the logistics of rolling stock through the Taishet station of the East Siberian railway. The relevance of the goal is the insufficiently developed transport and logistics infrastructure of the region located at the intersection of large transport flows, high costs of logistics operators for the empty tariff. Taking into account the prospects for the development of the station's transport and logistics infrastructure in accordance with the long-term development program of Russian Railways, there are opportunities to increase the range of types of rolling stock and cargo, including container ones. This technology, with timely provision of empty rolling stock for stations, will significantly increase the level of loading and unloading and routing of incoming empty cars. The practical significance of the considered measures is the possibility of reducing the load of some stations, reducing empty flights of rolling stock, increasing the profitability of transportation and the efficiency of using rolling stock by reducing its turnover. In General, for the network, the results will increase the capacity and transit volumes of container traffic from China to the Russian Federation, and stimulate the development of the transport business.

In article the algorithm of operation of the existing regime automatic equipment of transforming aggregates is considered. Earlier it was read that use of automatic equipment of switching on switch-off of reserve transforming aggregates is an effective remedy of lowering of losses in case of regulation of power of substation depending on tractive loading. Defining factors of assessment of efficiency of automatic equipment are the current and temporal settings, and also restriction of number of switchings in days. The analysis of diagrams of tractive loading showed that there is rather large number of temporal intervals where operation of automatic equipment is ineffective. On the one hand it is connected to the fact that loading is above a point of equality of losses in case of one and two transforming aggregates quite short time, and automatic equipment connects the reserve transforming aggregate already in the course of lowering of loading and disconnects it after a temporal setting. On the other hand - operating restriction of number of switchings of the reserve transforming aggregate in days doesn't allow to gain the considerable economic effect. The decision on use of regime automatic equipment with the existing settings can be the positive if at the same time the estimated effect in the form of abbreviation of losses of the electric power is above cumulative damage from switching of the reserve transforming aggregate. Regime automatic equipment in most cases, it is necessary to consider not as means of obtaining economic effect, and as means of reliability augmentation of operation of semiconductor rectifiers at the peak moments of loading what in turn influences reliability of electrical power supply of pull of trains in general.

Method of calculation of reliability of rails are presented in article. Research of refusals and durability of rails on two directions of the West Siberian management of infrastructure for sites of a way with different operational characteristics is conducted. Dependence of a gamma percent resource of rails on axial loading of cars and the plan of a way is received. Conclusions about a possibility of reaching of the passed tonnage of rails in 1500 million tons gross are given.

The article considers the task of controlling the quality of work transport hub taking into account the performance given by stochastically independent Poisson counter and quasiresonance traffic flows. The problem is solved with the use of analytical and mathematical apparatus of Queuing theory. The results obtained in the article are supposed to be used to determine the forecast of the total free capacity of vehicles waiting for loading, the queue length of loaded vehicles (trains) in anticipation of unloading, the coefficient of use of useful volumes of warehouse complexes.

Analysis of failures bogie side frames of freight cars in the network of JSC «Russian Railways» for the period from 2006 to 2013. Disadvantages of the well-known constructions of trucks of the car of model 18-100. Mathematical modeling of movement of a wheel pair bogie 18-100, set the negative impact of the spread of the values of structural parameters of the chassis of the car on the indicators of its dynamic qualities and driving safety.
