Analysis of reliability of contact network devices on the Yekaterinburg-Chelyabinsk section
Damage to the contact network negatively affects the movement of trains: 70 % of failures lead to their delays. Breaks in the movement are more than an hour and in some cases reach three to four hours. The article analyzes reliability and failures of contact network devices on the South Ural Railway. The statistical data of failures of contact network devices from 2018 to 2019 are given, the nature of failures of technical means is determined. According to the map of climatic zoning, the share ratio of icy regions of the Russian Federation and branches of JSC «Russian Railways» is given. The sections of the Yekaterinburg - Chelyabinsk section are identified by climatic regions, which allows us to conduct a statistical analysis of failures in the selected sections associated with ice formation.
