ABSTRACT
The purpose of the work is to analyze the direct impact of the relevant departments and divisions on the organization of the movement of trains that are delayed due to unexpected technical reasons and the causes of delays. The reasons and the names of the reasons for the delay ofpassenger trains in railway stations and stations were mentioned.
Keywords: unexpected technical reason, caught train, ,direct effect, department and division, passenger train, name of reason.
Цель работы - проанализировать непосредственное влияние соответствующих управлений и подразделений на организацию движения поездов, задерживающихся по непредвиденным техническим причинам, и причины задержек. Названы причины и названия причин задержки пассажирских поездов на вокзалах и вокзалах.
Ключевые слова: непредвиденная техническая причина, задержанный поезд, прямое действие, отделение и отделение, пассажирский поезд, название причины.
INTRODUCTION
The main goal of any transport industry is to ensure the effective organization of the transportation process, timely elimination of any factors that negatively affect it [1-7, 9, 13]. In particular, one of the most important tasks is to prevent excessive inefficient time losses caused by unexpected technical or technological causes of trains at railway stations and routes in the implementation of the main purpose of rail

transport, that is, the delivery of transported cargo and passengers to their destination [4-8, 10-12]. However, in practice there have been cases of trains being caught in railway stations or passages for unexpected reasons over the times specified in the technical standards [10-13].
Nowadays, the reasons for such a catch, that is, the delay of any trains, are reflected in the graph of the movement of trains that are performed, indicating the reasons that caused it[1, 6, 9, 12, 13].
When analyzing the motion graph of executive trains, the analyst engineers determine exactly which rail department or farm the reasons for each delay belong to.
DISCUSSION AND RESULTS
Based on the analysis of the conducted scientific [1-13] and practical work, the reasons for the train delay (interception)were determined at the by section of railway departments and farms, as well as the passenger transport enterprise, and the result was presented in the form of a table (Table 1 and 2).

CONCLUSION
The fact that trains at railway stations and peregons stand according to unscheduled, unexpected lessons is directly influenced by the fact that several relevant enterprises and organizations, as well as technical aids, do not work in a normal state. In addition, the role of railway workers in the non-stop organization of the movement of trains and their carelessness in professional terms will always keep their relevance.
