It is considered the possibility of improvement of the international railway transportation of benzene and other related cargoes between Ukraine and the European Union countries for the carriage of these cargoes in tank containers. The volume of chemical cargo transportation to the EU countries to the rolling stock types for 2018 has been analyzed. The research of the effectiveness of organization of international transportation according to the criterion of the total hours of downtime by wagons under accumulation. The mathematical model of chemical cargoes transportation by wagons, wagon groups and container trains with the accumulation to the technical standards on the cargo diversions was elaborated. The models take into account the unevenness of the wagon arrivals to the accumulation points and observance of the number of wagons to the established norm. A comparison of the effectiveness of the two models of the organization of the chemical cargo delivery and it was defined a more effective version of transportation. It has been established that for more efficient using of the rolling stock and for the rolling stock circulation decreasing is the cargo transportation by trains which consist of cisterns or/and tank container carriages. The influence of the components of the rolling stock circulation and its value are analyzed. The research of the cost of benzene transportation in cisterns and tank containers for the individual diversions was studied. According to the research results the cost of benzene transportation by platforms of the railways ownership is less than twice in comparison to private cisterns and tank-containers of the Ukrainian Railways fleet. These recommendations will improve the process of transportation and increase of volumes of international cargo by railroads between Ukraine and the EU countries.
