The importance of the problem under study is related to the need to solve a number of problems arising with the formation of long-freight trains. The purpose of the article is to analyze various brake systems of wagons of various lengths. The primary method for studying this problem is modeling, which permits to consider this problem. The article presents the results of studies of gas-dynamic processes taking place in the brake line of the train during braking, as well as the results of calculations of the instantaneous values of forces in the automatic coupling devices of rolling stock in the train during braking. The study results can be used to analyze the formation schemes of freight trains, especially long-base ones, and developing a new design of a freight-type air distributor.
