Simulation of train flows on the section Ust-Ilimsk – Khrebtovaya to increase throughput

   Increasing the capacity of the railway transport has been and remains one of the main tasks, which is given quite a lot of attention at the present time. In modern conditions, in order to strengthen the throughput and carrying capacity, it is important to tighten the traffic schedule, make fuller use of the existing infrastructure and technical means, use modern intelligent control systems and other organizational and technical solutions aimed at processing and forming a larger number of car traffic and train traffic. In this regard, the article proposes to consider the section Ust-Ilimsk – Khrebtovaya, to simulate its work when introducing a system of interval regulation of train traffic and to determine the possibility of passing more trains. The train schedule on the section is not intensive due to the use of semi-automatic blocking and one main track, as a result of which a small number of trains are skipped, and the carrying capacity of the line is small and does not allow increasing freight traffic, while transporting more cargo is an urgent task for this region.
   In order to increase the capacity of the Ust-Ilimsk – Khrebtovaya section and increase the further prospects for its use, it is proposed to model and calculate the possible number of trains that can be passed through the section when introducing, for example, Anaconda train interval control systems. The modeling of the work of the section consists in the development of an algorithm and the construction of flow models reflecting the arrival and departure of trains at the main stations of the section, which makes it possible to identify the time reserves in the departure of a larger number of trains. Based on the results of modeling and calculations, a list of train flows of the section is built, a proposed train schedule is built and its indicators are calculated. At the end of the article, a conclusion is made about the prospects for the use of innovative technologies in the field of interval regulation of train traffic on the Ust-Ilimsk – Khrebtovaya section.
