Abstract
The article considers the issues of equipping the divisions of Transenergo and the Traction Directorate with devices for mechanical removal of ice, vibrating pantographs and pneumatic drums. The method for assessing the risk of damage to JSC Russian Railways from the formation of ice on the contact network wires has been improved due to the lack of devices for removing ice from the contact wire in the required quantity in the structural divisions of Transenergo and the Traction Directorate. The levels of failure frequency and severity of their consequences due to ice formation have been proposed. Damage risk matrices and recommendations for risk reduction for each level have been compiled. Determination of the need to retrofit the divisions of Transenergo and the Traction Directorate with devices for removing ice is based on a comparison of the costs of restoring the infrastructure under current operating conditions and after retrofitting.
