Цель: Определение закономерностей изменения технического состояния верхнего строения пути на участках, расположенных в зонах с суровыми климатическими условиями с целью проектирования системы содержания пути в условиях Арктики. Методы: В ходе исследования проведен анализ таких основных показателей технического состояния верхнего строения пути как дефектность его элементов (рельсы, скрепления, шпалы, загрязненность балласта) и отступления от норм геометрических параметров рельсовой колеи (уширения, сужения, положение по уровню, перекосы, просадки, положение в плане). Анализ данных производился в соответствии с разработанной моделью зависимости изменения параметров технического состояния верхнего строения пути от наработки тоннажа и срока в годах. Результаты: На основании наблюдений определено изменение затрат на содержание пути на линиях, расположенных в условиях продолжительного зимнего периода в части неисправностей рельсовой колеи и дефектности элементов верхнего строения пути. Практическая значимость: Результаты исследования предназначены для разработки системы планирования работ по техническому обслуживанию и ремонту пути в условиях сурового климата.

Purpose: To determine legitimacies of changes in technical state of railway permanent way in the areas with harsh climate conditions with the purpose to design track maintenance system in the Arctic conditions. Methods: During the study, an analysis of main indicators of permanent way (upper construction) technical condition was carried out such as the way’s element defectiveness (rails, fastenings, sleepers, ballast pollution) and faults of geometric parameter norms of rail track (widenings and narrowings, alignment by a level, sags, subsidences, position in a plan). Data analysis was carried out in accordance with specially created model of the dependence of changes in the parameters of permanent way technical condition from a workload tonnage inclusive of annual periods. Results: Based on the observations, the change in track maintenance costs for the lines located in continuous winter conditions was determined. These are costs, related to railway track faults and defectiveness of track superstructure (permanent way) elements. Practical importance: The results of the study ‘re intended for the work planning system development on track maintenance and repairs in harsh climate conditions.
