description: This work is dedicated to assessing the operational suitability of the pole under conditions of icing and contact wire breakage. The object of the research is a metal pole made of bent channels for railway contact network supports. The subjects of the research are the assessment of the strength and stability of the pole under operational loads during icing and contact wire breakage. During the work, general concepts of the contact network pole design are presented. The construction of a digital model in a CAD system is considered, and the geometry is prepared for static analysis using the finite element method. A finite element model of the pole was created, and mesh convergence was assessed. Based on regulatory documents, loads during icing and contact wire breakage were selected and calculated, and static calculations of the studied structure were carried out. The results identified the dispositions of maximum stress concentrations and examined pole displacements under external influences. A stability analysis was performed, and stability margins were obtained for two calculation cases. Based on the analysis of the obtained results, a conclusion was made regarding the operational suitability of the pole.
