The article examines the relationship between the structural parameters of reinforced concrete poles in the overhead contact system and the reliability of the catenary operation. Based on an analysis of the contact system's configuration and the characteristics of supporting structures, approaches are proposed for assessing the technical condition of reinforced concrete poles, taking into account deviations from the vertical and the direction of inclination. A mathematical model is presented for calculating the deviations in contact wire stagger and height under various pole tilt angles. The results contribute to improving diagnostic accuracy and preventing emergency situations in railway power supply systems.
