Abstract. The article describes the main strategies for maintenance of track infrastructure that are used on Russian Railways. Their advantages and disadvantages are analyzed, and the transition to a predictive maintenance strategy as the most effective is justified. The directions for adjustment of the current regulatory framework aimed at supporting the predictive strategy are proposed.

Abstract. The article discusses the need for basic repair works in modern operating environment. There is shown in the article that the prompt repair determination should be carried out based on the information of the actual track condition. At the tactic level repair determination should be realized on the basis of a forecast of the track condition, taking into account its possible changing in operating conditions. At the strategic level for the long term, repair determination should be realized by the aggregating standards. There is also noticed that a special class of repair works focused on eliminating of the long unevenness is necessary.

The issues of predicting the failure of rails in excess carried tonnage, as well as the issues of repair determination on of mountain passing track sections in the horseshoe curves are considered.

Thermal method in control of fatigue cracks in welded superstructures of bridges

Keywords: steel bridges, fatigue cracks, non-destructive testing methods, infrared thermography.

Soloviev Leonid — Ph.D., Siberian State University of Railway Engineering, Associate Professor «Bridges», head. Department of Siberian Research Institute of Bridges. Novosibirsk, Russia. E-mail: lys111@yandex.ru, SPIN-code: 3943-2050.

Abstract. The issue is devoted to the experience of using infrared thermography in surveys of bridges. The results of laboratory and field studies on welded bridge superstructures are presented. In the course of laboratory studies, cantilever sheet samples with stiffeners under cyclic loading were examined. The configuration of the sample and the loading mode corresponded to the actual operating conditions of the bridge beams. As a result of laboratory experiments, the process of self-heating of the metal in the zones of the vertices of the fatigue cracks was shown, as well as the general process of temperature changes throughout the field of the sample. The study of temperature fields on one of the defective beams of a railway span under a passing load showed the applicability of the method for identifying and assessing the degree of development of fatigue cracks.
