This article describes the issues of historical tour to the development of the supporting facilities fleet on the electrified railways of Russia; it considers the causal relationships of defect formation in reinforced concrete supports of the contact line. For the given operating conditions, a 3D model of the interior bracket-type reinforced concrete support was created in the SolidWorks software package. Using the SolidWorks Simulation module, the engineering review of the reinforced concrete support tension was made using the developed computation algorithm. 3D images of the support model were visualized from operating loads under design conditions and the values of the strain in the support height subject to the exposure to additional factors.
