This article focuses on the issue of optimising the transport process of cargo-intensive sections analyses the section capacity and outlines the most relevant ways of increasing carrying capacity and throughput today. In order to reduce capital expenditures for capacity enhancement the optimization task on revealing and determining the factors’ values influencing the carrying capacity was formed. Rational location of locomotive fleet on the sections allows to increase weight standards of goods trains on the one hand and on the other hand with useful track length less than 1050 m a reserve of locomotive capacity appears. On sections with low gradient up to ip < 8‰ the reserve should be used to increase running speed while on sections with difficult profile ip > 20‰ the reserve should be used to increase weight standards of the train. The proposed methodology made it possible to determine the optimum values of weight norms and speeds on the basis of the obtained values of running speed parameters and the division of the train traffic into three categories (light, mixed and heavy) using the optimum type of locomotive 2TE116. The results obtained prove the relevance of the study and show that the main factor that has a significant impact on carrying capacity is the locomotive performance. When determining carrying capacity the average train weight should be used rather than the weight standard set by the train schedule.
