Development of Proposals for Increasing the Efficiency of Using Domestic High-Capacity Rolling Stock in the South of Russia

The main trend in development of high-capacity rolling stock used in the South of Russia is specialisation of coaches. The article considers the advantages of double-decker trains compared to traditional single-decker trains. Double-decker trains make it possible to carry out multimodal transportation of passengers in conditions of increased demand and a decrease in alternative offers from other modes of transport, increase the capacity of passenger rolling stock, the transit capacity of the railway infrastructure, and ensure the most rational use of the dimensions of the rolling stock. As a result, the carrying capacity of railway lines increases with minimal costs since energy costs for traction and traction-related costs are reduced.

The authors analysed and constructed a model for replacing traditional single-decker rolling stock with more spacious doubledecker rolling stock. The dependence of the volume of traffic on passenger flow and a potential area of replacing single-decker trains with double-decker trains are shown. A nomogram is presented for the dependence of the volume of transport services for the population on the regularity of train schedule. A general algorithm for assessing and selecting potential opportunities for assigning double-decker trains in the South of Russia is considered.

Scenarios have been proposed for changing the category of transport services under the conditions of increased demand while replacing single-decker cars with double-decker ones. The annual effect from replacing single-decker cars with double-decker ones was calculated together with the total investment effect.
