Features of the calculation of the plan of forming single-group trains in market conditions

Abstract

The article is analyzing the possibility of using an additional parameter for the calculation of the formation of one-group trains, allowing to take into account the costs associated with the motion of rolling stock. A study was carried out at a number of railway sections of the Belarusian Railways aimed at identifying factors that affect the sectional speed of freight trains. The analysis of the obtained results made it possible to conclude that there is a relationship between the train category and its sectional speed. Depending on the traffic intensity and capacity of the site, the difference between the sectional speeds of transit and sectional trains in the investigated areas was from 2 to 18 %. In the development of the train formation plan, it is proposed to apply a new additional parameter for saving costs for cars and locomotives in transit trains Rn . Authors propose formulas for calculating the value of this parameter. The influence of some factors was analyzed including the train composition and mass, the length of the section, the power of the car stream on cost savings when using the proposed parameter in the calculations. The application of the parameter of cost savings in the cars and locomotives in transit trains makes it possible to justify the allocation of separate streams of car traffic for independent purposes, which would be considered economically unprofitable when developing a train formation plan based on calculations performed by traditional methods.
