Practical application of the idea of sustainable freight transport requires a significant development of the intermodal transport network in which rail transport plays an important role. It is indicated as an ecological, safe, fast and economic type of freight transport. However, an important matter conditioning its development and significance is the reliability of freight flows. In the literature research, there is a lack of comprehensive recognition of dependencies between the reliability of flows in intermodal network of rail transport and the disruptions and characteristics of the network. Therefore, the authors of the paper adopted an analysis of the impact of disruptions in freight flows in rail transport on the reliability of these flows. The paper assumes that the reliability of freight flows in rail transport is measured by the number of cancelled trains and an average delay time of trains. At the same time, it was also assumed that the impact of disruptions on the reliability of flows depends on the characteristics of the network itself. In conducted empirical research supported by regression analysis, the authors indicated relationships between the studied variables and identified gaps in the system for collecting information about disruptions on the railway network. The conclusion underlined in the paper is the necessity to develop a coherent system for collecting data on disturbances, which will contribute to the development of a model of knowledge management about disruptions and will allow to coordinate the network to increase its reliability.

可持续货运理念的实际应用需要大力发展铁路运输发挥重要作用的多式联运网络。是一种生态、安全、快捷、经济的货运方式。然而，制约其发展和意义的一个重要问题是货运流动的可靠性。在文献研究中，缺乏对轨道交通多式联运网络中流量可靠性与网络中断和特征之间依赖关系的全面认识。因此，该论文的作者对铁路运输中货运流量中断对这些流量可靠性的影响进行了分析。本文假设铁路运输中货运流动的可靠性是通过取消列车的数量和列车的平均延误时间来衡量的。同时，还假设中断对流量可靠性的影响取决于网络本身的特性。在回归分析支持的实证研究中，作者指出了研究变量之间的关系，并确定了系统中用于收集有关铁路网络中断信息的差距。本文强调的结论是有必要开发一个连贯的系统来收集关于干扰的数据，这将有助于开发关于干扰的知识管理模型，并将允许协调网络以提高其可靠性。
