Technical and economic evaluation of justification for preventing negative effects of feedback in local elements of interaction of rail yards

The operation of rail yards is characterized not only by direct links, but also by feedback in the local elements of interaction, resulting in a violation of interaction conditions between adjacent elements, which causes a negative effect on the state and functioning of the elements. The duration of the track occupation in the arrival yard depends on both its parameters: the marshalling hump and the operation of other elements of the yard located at the arrival yard in the direction of cargo traffic processing. Therefore, when choosing the rational parameters of the rail yards, attention should be paid to the existence of feedbacks in the local elements of interaction and conditions of their negative manifestation should be investigated in order to justify measures to eliminate them. In the article, the issue of improving the customer transport service quality by technical and technological modernization of railway enterprises was studied. Technical and economic evaluation on justification of measures for the elimination of negative effects of feedback in local elements of interaction of the rail yards is presented for practical use.
