Abstract

The paper presents the executed research on the influence of introducing scheduled trains on polygon operation carried out with the use of simulation model. The model shows the delays caused by infrastructure elements and by resources — train locomotives and car service station crews. Results show that priority trains deteriorate the parameters of polygon operation, decrease the schedule speed. Experiments with the exceed resources allowed to determine that infrastructure parameters play the main role. As a result, the introduction of priority trains is only advisable at the existence of polygon capacity reserve.
