Abstract. This article presents the new paradigm of assessment of condition of continuous welded rails. The importance of rail traffic safety on  sections of continuous welded rails and constant monitoring of its temperature-tensely condition is described. The most crucial causes of breakdown of tolerable temperature-tensely condition of continuous welded rails are analized. The stage-by-stage approach of creation and development of methods of control and assessment of continuous welded rails condition is represented according to statistics which is received by diagnostic aids and this methods was realized in the programme KAPS BP URRAN. Assessment criteria of escape probability data point V2 and complex coefficient Kk is given. The main functions and tasks of the programme KAPS BP URRAN are described. Basic output forms, which provide visualization of the results of assessment in the programme KAPS BP URRAN are represented.

Abstract. The intensive operational maintenance of the Moscow Metro requires from the used superstructure components a path of high durability with unconditional provision of passenger transportation safety. In the work presented in the technical plan are various studies, which are united by one goal - improving the maintenance of the way. The technology of hardening of metalware by the method of volume-surface hardening used in the subway (screws, butt-end bolts, rail fastening spring clips) does not increase the cost of production, provides technical possibilities for increasing static and fatigue strength. Developed measures to improve the operational content of insulating rail joints provide the basis for the safe operation of the track. Experimental work on induction welding of rails is also aimed at increasing the safe operation of the track.

Abstract. In the article the author considers the problem of stability of the track when operating switches under the train load, the cause of this phenomenon. Compares aggregate-flow technology of production of reinforced concrete bars for track switches and the technology is a «long stand». Describes a new construction of concrete Foundation for turnouts, namely reinforced concrete flat boards, which attach the rail elements to the pads is performed by means of elastic terminals. In the end, the conclusions about the application of new technologies manufacturing and designs concrete base for turnouts.

Abstract. The article describes the history of the structure of rail angle; the main factors that determine the tolerances on rail angle; describes a device that measures rail angle by manual measurements; found that wave-like change in the value of rail angle in the longitudinal direction in both straight and curve sections of the rail-track leads to increased lateral wear of rails

Abstract. Summary Justification of application bridge-tunnel in the conditions of permafrost, the boggy district and seismic regions is presented. The proposed constructive solution of the installation of the sheath tube mototunes of the damping elements and the mathematical modeling of process of interaction of rolling stock roadway mototunes. It is shown that, using as a support jacks, variable rigidity of the track varies depending on the noise parameters of the rolling stock and Jack and takes into account not only the oscillatory and wave processes including rolling stock, but also anisotropic properties, which are governed by supplementary reinforcement in elastic chambers of the Jack in the three main directions of anisotropy. This reduces construction costs compared to traditional construction methods, ensuring a relatively quick installation environmentally not affecting the environment mototunes on pneumatometer.
