Purpose: An approach is considered in the article to the assessment of stability main conditions related to maintaining the equality of incoming and outgoing wagon flows and also related to the conditions of track freedom in the parks of local line sorting systems. Methods: The task is settled with the use of (mathematical) analysis, probability theory and fuzzy set theory. Results: The study of arrival probabilities for trains with local cargo for a disbandment leads to the conclusion that trains with wagons for more than two destinations constitute the norm. The performed calculations show that in the sorting system of local line stations at any time moment there should be free at least three tracks at the expense of arriving and departing train intensity. Practical importance: The proposed approach makes it possible to specify the assessment of work stability for station sorting devices and to increase the reliability in meeting set deadlines for goods delivery.
