The research of natural statics and damages connected with them is difficult in consideration of their random occurrence. Making a decision about necessaries and effectivities of resources usage of the lightning surge protection and about the choice of a suitable protection method, should be preceded by an estimation of the risk due to damages lightning discharges. In the report, the risk analysis of damages of the railway traction and of the control command and signaling equipments due to lightning discharges for a real case of damage, is represented. In the risk analysis, a fragment of a rail track in which lightning discharges appeared, was taken into account. The results of these occurrences estimation, calculated by the LIOV software, taking into account real parameters of the system, have been also represented.
