The issue of low-density railway lines operation which is topical for railway transport is considered in the article. Operation of the type of lines in question is non-value added, though the suppression of its activity is impossible due to political reasons. Modern research in the given scope is aimed at cost cutting in performance of such lines at the same time maintaining operational reliability of equipment and its efficiency. Low-density lines may be used as polygons for implementation of technical and engineering solutions which in future can be applied at the routes with high-density traffic. The required number of operating personnel to fulfill train and shunting service at a certain direction is one of the topical issues of the study. The lack of train and shunting service leads to low workload of operating personnel. The dependency model of the required number of station operators from the number of through freight trains and local cars at a section was built in the study. The model makes it possible to predict the required number of station operators in case of change in the volume and type of train and local service. The assessment of complexity index of the presented algorithm and the obtained model was carried out. A conclusion was made on adequacy of the model in question; an interpretation of the obtained results as to the number of station operators and the reduction of their work load by means of minimal-manning technologies was carried out. The simplicity of calculations and the algorithm is one of the advantages of the model in question.

Key words:
Low-density lines, workload of operating personnel, carrying capacity, railway transport
