Purpose. In the paper it is necessary to: 1) find out the causes of turnouts faults to determine diagnostic features failures; 2) consider the requirements structure, purpose components of turnouts, work and technology of their maintenance to determine the construction of the economic activities related to system to the turnout’s maintenance; 3) substantiate the possibility, necessity and prospects of automated diagnostics turnout’s implementation; 4) elaborate a prototype of an automated hardware and software system for the turnouts control parameters and perform diagnostics on them. Methodology. In the paper possible turnouts faults were presented and manifestations and influence on its work were shown. According to the current technology works the process analyze of turnouts’ maintenance was conducted, were defined the basic performed operations during the examination of appearance, parameters and check the repair or replacement of parts and assemblies. Based on the analysis of reasons of turnouts malfunctioning and their fixes were systematized types of damages and ways to deal with them, an information scheme of troubleshooting were created, opportunities and limits of automating the process of diagnostics were identified and compared with the existing method of turnouts maintenance. A diagnostics system block diagram was created, an algorithm of its work was developed and established main basic principles of operation. Software and hardware to determine the turnout’s state considering diagnostic performance of points in use were applied. Findings. During the experiment was created a method of automated turnout’s diagnostics with AC electric drives, managed centrally. The results of automated hardware and software system make it possible to control turnout’s parameters and perform diagnostics on them. Originality. Authors created the method of turnout’s state determination by current curve and its spectral composition in the circle of turnout electric motor. The de hardware and software centralized point’s diagnostics complex was developed. Practical value. Thanks to the obtained results the operation safety due to a time workers decrease in the area of train’s movement is increased. The human factor in the performance of measurements is eliminated. Hiding and concealment the facts of turnouts malfunction are not possible.
