Abstract. The article is devoted to the slope stability assessment using the limit equilibrium and finite elements methods in a three-dimensional formulation of the problem. As the object of research, a section of the Sakhalin railway on Pugachevo – Makarov site has been chosen which is in danger of the activation of landslide processes. The results obtained correlate well with the current state of the slope; however, comparing three-dimensional calculations by the limit equilibrium and finite elements methods there is an uncertainty associated with the landslide body configuration in plan.

Abstract. The article is devoted to the assessment of the dependence of the change in the canting on the design of the railway track and the actual transit tonnage. The article presents the results of experimental studies conducted on the Moscow railway. Based on the test results, the influence of the track structure and the actual transit tonnage on the canting is estimated. The article summarizes the conclusions and suggests the direction of further research.

Does the large massiveness of the elements of the upper structure of the path increase its reliability?

Keywords: mass of elements of the upper structure of the track, joint-free track, stability of the track, ballast resistance to sleeper shear.

Abstract. The paper presents proposals for optimizing the organization of the working process of snow removal equipment based on automated monitoring. As the proposed basic elements of the analysis of the operation of snowblowers, the data obtained using the software of the ACS SPS and the sensors of the AS KRSPS installed on the machines of the Novosibirsk mechanized distance of the infrastructure at the station Inskaya are used. The article calls into question the need for a standard for the number of unloadings and the volume of filling a snowblower and proposes to approach the process of snow fighting from an economic point of view, namely, to pay for high-quality cleaned paths, fuel savings and maintenance costs. It is advisable to count the operating time according to the length of the cleaned paths or the time of the operating mode, which takes into account the main task of the machine and has a natural mathematically substantiated connection of one parameter with another.
