Abstract

The article is devoted to building of freight trains for transportation of containers with railway transport at speed of 200 km/h. The article considers building experience of the high speed freight trains for transportation of containers at speed of 350 km/h. Main technical characteristics of the rolling stock, involved in freight high speed railway transportation in foreign countries are analyzed. The purpose of the article is to discover design features of the rolling stock for freight transportations at speed of 200 km/h and in modeling of the braking processes during electro pneumatic and pneumatic braking of the rolling stock from speed of 200 km/h to 160 km/h. The concept of the rolling stock for high speed freight transportation of containers is proposed. A specialized platform with bogies, disc brake and air-spring suspension Installed on it is used as a rolling stock. A brief description of the brake system is given; its main features are shown. A pneumatic scheme of the container block of the braking equipment and the general view of container block is given. Classified freight train, which consists of 30 platform cars and has two locomotives on each side is proposed for high speed transportation. Brake distance during electro pneumatic and pneumatic braking at freight train speed of 160 km/h is calculated. The results of calculated studies of the trains braking efficiency are given, which showed that at the speed of the freight train of 200 km/h, the brake distances at electro pneumatic and pneumatic braking are represented by 1472 m and 1571 m respectively, which corresponds to the technical requirements of the European Union TSI. Key words: high-speed freight trains, container, speed, brake distance, disc brakes.
