The work is devoted to solving an urgent task - to develop a complex of scientifically-based proposals of conditions and measures that provide technologies for the operation of electricity traction networks based on energy and resource conservation. The article deals with theoretical and practical issues of technology development and repair of the contact network (CN) on state to ensure the process of passenger transportation. The technical criteria for the status of CN are determined and the technologies of maintenance are offered as monotonically changing parameter control. The set of diagnostic and reliable indicators is offered. Generalized structural diagrams of the system of assessment of the condition of the CN and the ranking of repair work taking into account the possible impact of defects. It is proposed to rank them by three characteristic features: first-class failures in which the CM as a system completely loses its capacity; type 2 failures (partial) in which the effectiveness of the functioning of the CM decreases; failures of the 3rd kind - are noted in the elements of KM for the time of work on the current composition and repair.It is shown that the use of maintenance system according to the state with parameter control is possible if: operating conditions of the CM conditions do not allow the work to failure; KM devices have high functional value with insufficient degree of reserve; there is a high level of operational adaptability and repairability.The basic criteria of the condition of the CM and the quality of current flow are summarized. Technologies based on the synthesis of probabilistic methods of parameter estimation, real diagnostics and simulation modeling of the CM state are proposed. The basic criteria of the condition of KM, which allow to estimate the resource saving during maintenance and repair, are defined.
