The advantages of introduction of modular freight electric trains in comparison with freight trains using locomotive traction are described, the main prerequisites for introduction of a distributed multiple-unit freight traction are indicated. The results of comparison of the technology of transportation with traction by locomotive situated at the head of the train and by the train with self-propelled coaches, as well as the analysis of traction calculations of two types of trains are suggested. The international experience of developing freight trains with distributed traction is described.The main directions of implementation of the concept of accelerating freight transportation on the territory of the Russian Federation are noted. It is concluded that in modern conditions, when speed becomes an economic category, it is necessary to create rolling stock of a new generation (wheel and magnetic suspension), and introduction of freight trains with distributed traction becomes extremely relevant.
