The constant increase in the number of passenger trains has led to the fact that the semi-automatic blocking does not cope with the timely passing trains through the section. This article discusses the carrying capacity of railway section "N-B". The reserve capacity of this section is practically absent, the removal rate of passenger trains increases, which negatively affects the work of the entire railway section. Disposable and required carrying debility is determined. The method of increasing the capacity is chosen for each line depending on the given dimensions of movement, local conditions and technical and economic efficiency of different options.
