The article presents the results on the development of software for computer processing of running dynamic tests on the impact on the railway track. The software, compiled using the modern C# programming language, is a refinement and improvement of the previously used DynTesT software package and allows you to significantly automate all the basic procedures for entering initial information and processing test results. The introduced improvements make it possible to minimize labor costs for identifying technical failures that occur during the registration of dynamic processes and quickly rebuild the structure of the program code to eliminate possible errors during manual entry and reduce the processing time for tests on the impact on the railway track
