The acceleration of the world commodity turnover, the growth of its volumes and structure changes exerted influence on the role of transport and logistics in the world economy. In recent years the intensification of relations between the countries and the appearance of interstate transport and logistic systems are observe ed. The significance of practical and theoretical questions of the transport and logistic infrastructure research is increased. The analysis of approaches to classification of logistic and transport infrastructures is carried out. The author's vision of transport and logistic infrastructure content is shown. The classification of objects of transport and logistic infrastructure is developed.

Great attention to the research of operation of the train brake system of different of formation plan has been paid for many years. These researches in relation to heavy freight movement are especially actual. From the point of view of lengthway dynamics the long freight trains formed from long-wheelbase cars including jointed type cars are of absolute interest.

The development of torsional vibrations of wheel and motor blocks of locomotives taking into account coupling qualities of wheels with rails is considered. The dependences between parameters of this electromechanical system are established.
The possibilities of increase in fuel profitability of transport engines are considered. The operation analysis of diesel diesel-generator 18-9DG installation on the diesel characteristic in two options (standard and experimental) is carried out. It is shown that during the operation on the experimental diesel characteristic the introduction of measures providing removal of the line of operating modes from border of stable operation of the turbocharger isn't required.

The business activity analysis of JSC "Russian Railways" from 2008 to 2016 is provided. The business reputation of JSC "Russian Railways" was calculated by the method of excess resources, the method on the basis of the volume of product sales (operations, services). The evaluation method of business reputation based on the concept of value added is considered.
The polynomial laws of change of traverse speed and length of the passable way realizing the gradient junction of management system from the initial stationary mode of functioning to the given stationary mode are provided. The absence of dependence of length of a brake distance on an order of the polynomial law of speed change of a control object is shown.
The operation stability of automatic equipment significantly depends on the traction current asymmetry in rail lines. Its primary source is the longitudinal and transverse asymmetry of resistance of rail lines, and the mutual inductivity of rails increases this asymmetry. The processes of the asymmetry origin of the traction current and the reasons of its change in time are analyzed. Ways of reduction of this asymmetry are offered.
The characteristic of the applied envelope buildings from sandwich-structured composites is given. Their advantages in comparison with the applied materials for wall panels are reflected. The classification of lightweight constructions of walls and coverings by types of effective heaters is given. Some shortcomings of the applied polymeric materials (chemical and fire hazard, small service life) are shown.

The labor protection is the priority problem of the state policy directed to improvement of working conditions. Complex researches on assessment of processes of oxidizing destruction of heat-insulating materials for cars are conducted; the detritus of materials are identified.
O.S. Lokteva, D.A. Loktev
The modern control system of labor protection based on risk-focused approach is presented. The regulatory legal base of this approach, the injury prevention methods on modern production are considered.
S.A. Dontsov, V.S. Chaplygin
The retrospective transition from three-stage control in the field of labor safety to the complex system of state estimate of labor protection on the production object in JSC "Russian Railways" is considered. In order to reduce the labor costs, minimization of paper work and increase in a safety culture of work the module of automation is offered.
