The graphic dependences of lengthening and effort in each flexible element of fastening of freight on the value of the coefficient of the longitudinal dynamics of the car are made for the first time on the basis of the earlier obtained analytical formulas. The results of calculations proved the possibility of the safety and reliability of the transportation process without commercial damage in transit.

The causes of wear of the center plate arrangement are considered, the review and the analysis of the patents offering problem solutions of increase of durability of the arrangement are carried out. The new problem solving by means of self-organizing systems is offered.
The analysis of the existing technical solutions of wheel pairs of rolling stock of differential execution is made and their classification is offered. The functioning of wheel pairs with hard and easy fit wheels on the axle is considered, their advantages and disadvantages are defined. The basic requirements are formulated, and the optimal design of wheel pairs of differential execution for Railways of Russia will meet these requirements. The technical solution for improvement of steady interaction of "wheel-rail"system is proposed.
It is proposed to increase the fatigue strength of solid-rolled wheels by means of local heat treatment of disks. Locally reinforced areas are put evenly with external and inner side of the wheel disk in places of transition a disk into a rim and a hub.
The history of a periodization of inventions and application of black-and-white television (monochromatic) in systems of picture signal transmission of objects of railway transport with representation of chronological dates is executed.
Asymptotically optimal algorithms of maximum likelihood in problems of recognition and estimation of signal parameters under influence of additive noise with arbitrary known univariate distribution of probabilities are considered. The analytical equations of optimization (block diagrams) and quality indicators of their work possessing the maximum possible (potential) noise immunity on the given class of distribution of noisy signals are received.
The issues of increase of parametric reliability of transport electrotechnical systems are considered. The method of tapering areas intended for optimal parametric synthesis of electrotechnical systems on the criteria of working capacity margin is stated.

The article is devoted to the analysis of the main approaches to management of transport systems from the viewpoint of adaptability and intellectual management. The indexes of the authors studying the application of artificial intelligence techniques are given. The general concept of the transport system as a set of the elements functioning in the conditions of changeable environment is considered, and on this basis the corresponding ideological platform is postulated.

The article is devoted to the analysis of possible approaches to the assessment of the influence of human factor on the safety and efficiency of train operation. The analysis of existing approaches is presented. It is shown that the questions of the role of human factor should be given attention to, both at the design phase, and at the implementation phase of technological processes in transport.

The presented constructive decisions on this installation demand the careful analysis on the substantiation and choice of three basic systems: the control system of frequency-controlled asynchronous electric drive, the control system of ensuring of precision supply of impregnating material on end coil isolation, and the control system of spectral composition of thermal radiation.
The main aspects of transition to through polygon technologies of operation of engine yard and the contingent of locomotive crews are stated. The recommendations for the training of personnel of control center of traction resources of different levels of organizational hierarchy are made.
Transition questions to a new control system of traction resources are taken up, and the approaches allowing to prove this system are offered.
