Innovations in Production of Moscow Underground Railway Carriages

Abstract

AbstractThe article discusses the main directions of development of the design and technical characteristics of the Moscow underground railway carriages from the beginning of the 1930s to the present time in connection with the construction of the subway in large metropolises of Europe, Asia and the United States. The influence of changes in railway carriages building on passenger traffic is analyzed. Five generations of equipment were traced by the design of the railway carriage and bogie; the shape of the driver's cab; engines, drive, control and other electrical equipment; ventilation and air conditioning; brakes; auto-coupling device; protective devices; passenger comfort. Manufacturers of second-generation equipment achieved a smooth start-up and reduced amount of electrical equipment repairs. During the creation of the third-generation equipment, the improvement of the rolling stock went in the direction of increasing the capacity of the railway carriage. The lightening of the body, bogie and auto coupling due to changes in the load-bearing structure, materials and finishes led to an improvement in the smoothness of the ride and a reduction in the weight of the railway carriage. The fourth-generation equipment was created with the aim of increasing the reliability of components and parts, carrying capacity, increasing the average and structural speed, and reducing operating costs. The modernization of equipment in the fifth generation of rolling stock equipment was aimed at providing comfort and increased passenger capacity.KeywordsInnovationsMoscow undergroundRailway carriageTechnology generations
