Objective: Considering the effectiveness of the formation and handling of heavy trains. Revealing how the organization of the movement of such trains affects the carriage and traffi c capacity of railway sections. Methods: To solve the problem, graphic and analytical methods of mathematical modeling, scientifi c methods of collecting and processing statistical data, modern achievements in terms of general principles and methods of risk management were employed. Results: A formula has been derived to determine the rate of removal of freight trains. The analysis of the infl uence of the values of the freight trains and heavy trains spacing on the removal rate has been conducted. Practical importance: As the main alternative to increasing the size of traffi c on the main cargo-intensive directions, with a shortage of carrying capacity, it is proposed to use the technology of heavy traffi c. In modern market conditions, an increase in the weight and length of a freight train is one of the main reserves for increasing carriage and traffi c capacity. Passing heavy trains, we achieve growing carrying capacity. The consistency of these measures has been proven. An increase in carriage and traffi c capacity is considered with the aim of increasing unifi ed weight norms.
