Abstract
Currently, the proportion of trains of increased weight and length is growing. There is a need to study the impact of changes in the structure of train traffic on the capacity and infrastructure of the site. With the help of simulation modeling, the throughput of the site is investigated when passing a heterogeneous flow in a changing infrastructure. The issue of determining the required number of elongated tracks to handle the flow of trains of a given structure is being investigated. The expediency of introducing strict specialization of the station's tracks is revealed. The capacity of the station is determined with a different number of elongated paths, the volume of the input stream and the ratio of jets in it. The coefficients that bring the calculated throughput to the one obtained as a result of the simulation are calculated.
The level of permissible payload of the tracks of the extended cargo fleet has been determined. Based on the experiments, it was concluded that the more diverse the train traffic is in structure, the less dense it should be.
By adjusting the size of the input stream, it is possible to improve the use of the station infrastructure.
