The article considers the problem of inconsistency between investment in reconstruction measures and new projects for the development of railway stations. Direct elimination of infrastructural errors requires serious material costs. The authors propose a way to reduce the negative consequences of structural imbalances in station design by means of simulation modeling. The simulation model most correctly displays the structure and harmoniously superimposes the technology of station operation, as well as takes into account the interaction of random technological processes and dispatch control. This is a promising approach using domestic developments in this industry. Since the cost of transportation infrastructure is extremely high, there are increased requirements for calculation and planning methods. The article describes the importance of using simulation models in the design of transportation objects. Examples of experiments on the model are given, proving the correctness of the calculation results. An important point is the automation of the process of building a simulation model, thanks to which random errors and inaccuracies leading to incorrect financial costs are excluded.
