Ensuring current collection on electrified railroads is usually tied to the optimization of parameters for current collectors and catenary suspensions in order to stabilize the catenary depression. Presently there is a substantial increase in train traffic speeds and the power of electric rolling stock. Catenary suspensions with definite parameters can be created for the imminent electrification of railroads to operate in new conditions. Modernization of the catenary network of existing electrified railroads aiming to ensure this can provoke serious difficulties. The most economical way of solving this problem for new conditions on lines which were electrified 10-20 years ago is to apply improved current collectors not requiring capital reconstruction of the existing catenary network. Such are current collectors with self-regulating mechanisms or follow-up systems with reverse communication, differentiated by regulated or regulating parameters and the installation of self-regulating mechanisms in various assemblies. When designing these it is also necessary to choose and verify values of a series of supplementary constructional parameters of the interacting system: "current collector-suspension", so that conditions giving rise to auto-oscillations will not be created. This article addresses the task of examining these phenomena by the example of type TS-1M current collector with rolling foundation, and proposes criteria for evaluating self-regulating devices to be used on planning and testing units and line tests. It is necessary to work out the structural schema of the system, compose calculation equalities, and carry out their analysis for concrete data characteristics. The article concludes that for the system: "current collector with self regulation--catenary suspension system" a verification for stability in transitory conditions is obligatory. The criteria defining the system's stability are overcontrol, time regulation, and the oscillation indicator. The methods stated above allow calculation of the current collector parameters which ensure its stable operation in the transitory operating modes.
