The solutions actual for the theory and practice of the tasks connected with the estimation and increase of efficiency of interval control of train operation are submitted. The new indicators of efficiency and their application are considered. The method of interval control of train operation is given. It allows to increase the efficiency, including to provide possibility of traffic with a shorter interval.

The estimated probability of emergence of risks and their influence on performance of the main indicators of transportations is made; parameters of threshold values of possible risks are established. On the basis of the efficiency analysis of existing measures the map of reserves of quality in compliance with freight delivery time-frame is formed. For the assessment of influence of risk factors it is offered to use modeling of scenarios with application of logical-and-probabilistic methods.

Mathematical models, algorithms and programs for calculation of routes and freight traffic in transport terminal networks of multimodal transportation operators with own developed polymodal (auto-avia-railway) network of routes are developed. The description of developed algorithms and the program is maid. The examples are given.
S.S. Poznakhirev
The analysis of the transport market condition and its influence on productive and economic indicators of operation of railway transport is carried out. The possible mechanisms of stimulation of operating efficiency of JSCo "RZD" directed on the solution of the tasks set for railway transport are offered.
L.V. Shkurina
Theoretical and organizational problems of competitiveness management of transport production are investigated. Economic methods of management of competitive advantages of companies functioning in the transport market are considered.
S.N. Beryakov
Article is devoted to the influence assessment of implementation of investment programs of railway transport development on the economy of regions of the Russian Federation. The investment volumes into the transport branch in regions with a favorable economic status are presented. The problems of development of JSC RZD infrastructure are considered.
Yu.A. Sheptukhina
The quality indicators of transport service of freight owners as the main characteristics of competitiveness are considered. The effect of realization of measures directed on traffic safety is shown. It is one of the most essential characteristics of competitiveness.

Results of calculation of the shift of freight across the car, the lengthening and efforts in flexible elements of fastening at a variation of number of fastening elements are presented for the first time. Graphic dependences of the lengthening and the effort in each flexible fastening element are constructed. The necessary number of fastening elements where there are possibilities of ensuring their guaranteed durability without destruction that promotes stability of transportation process operation is established.
A.M. Ol'shansky
It is considered the control system of any organization from positions of two approaches: the classical doctrine about organizational structures and the algorithmic representation of systems. The offered approach can be used both in the analysis of the developed organization control systems, and in the new organizational system engineering.
A.B. Afanaskin, N.A. Taradin
The classification of incidents within a control system of services of the communication network of JSC RZD is considered. The analysis of various approaches to the creation of classifiers is carried out. It is offered to expand the scope of the existing classifier within the introduction of methodology of management of resources, risks and reliability analysis.
A.V. Gorelik, D.V. Soldatov
The general questions of an assessment of restoration time after failure of systems and devices of railway automation and telemechanics are examined. The method of modeling of technological restoration process of technique by means of functional networks is offered.
V. V. Krishtal'
According to requirements of Civil ‘ode of the Russian Federation the self-regulating organizations in construction are to qualify the technical and engineering employees for the competency certification. The main questions of improvement of the most popular model of certification, Uniform system of certification of heads and personnel of a construction complex, are considered; the practice of certification in SRO is analysed. The recommendations for its improvement are made.
V.A. Aksyonov, P.N. Potapov, A.M. Zavyalov
The possibility of modernization of the existing control system by labor protection in close interrelation with used on a network of the railroads methodology of resource management and risks at all stages of life cycle of objects and equipment on the basis of the analysis of reliability (URRAN) is considered.
Yu.P. Sidorov, E.Yu. Tolshchina
It is made the calculation of the net radiant flow and the temperature of a heated surface between parallel plates with the centers located on one axis at various distances between them.
O.S. Yudaeva, S.V. Demidov
The program and procedure of full-scale firing tests of the mock-up of the car of model 47K ü017 12033 are developed. The complex of ecological and hygienic and toxicological tests is carried out, and the recommendations on the use of modern the polymer constructional and finishing materials are developed.
A.A. Loktev, A.V. Sychyova
The questions of the registration of the wave effects and the properties of soil under the embankment of the railway bed on the basis of a ray-tracing method for the detection of a dynamic deflection of the track structure and the interaction force of a wheel and a rail are considered.
