On the content of transport and logistic infrastructure elements of macrolevel

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.
Key words: transport and logistic infrastructure, transport and logistic systems, objects, elements, content

Change cycles of operation stability of automatic equipment on electric traction sections

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.
Key words: rail lines, rails, rail circuits, automatic locomotive signaling, noises, of alternating traction current asymmetry
