Loads from ice and frost formations on the wires of the contact network worsen the quality of current carrying and contribute to the emergency situation. The article presents the analysis of methods and sets of equipment for diagnostics of ice and frost formations on the wires of the contact network. Elements of diagnostic equipment form an information system, the end point of which is the energy dispatcher's console. It is shown that the composition of the diagnostic equipment is determined by the type of contact suspension and its place of installation. The variety of methods used for diagnostics of ice on wires of the contact suspension shows the complexity of the problem to be solved.
