Abstract
The presented article is devoted to the study and assessment of the railway polygon capacity in the context of the introduction of a forced train schedule, characterized by the integration of connected trains into the traffic system. The authors conduct a comparative analysis of the methods for determining the capacity, based on a comparison of the results obtained by applying an analytical formula used in practice and the results generated by simulation modeling. The paper concludes that it is advisable and necessary to use a specialized software package (IMETRA system) to build realistic models of railway track operation that adequately reflect the complex interactions of the elements of the transport system. The article presents the results of experimental studies carried out on the basis of a simulation model developed at the Ural State Transport University, aimed at analyzing the impact of a forced train schedule on delays for various categories of trains. The results obtained make it possible to evaluate the effectiveness of the forced schedule implementation and identify potential bottlenecks in the functioning of the railway polygon.
