Logistic indicators of locomotives of diesel traction in Marokand-Kattakurgan section of Uzbek railway

Abstract

The results of a study on the substantiation of the parameters of the logistical indicators of rail freight traffic implemented by diesel locomotives of the UzTE16M3 series when moving with stops on the hilly-mountainous section of Marokand -Kattakurgan of the Uzbek railway are presented. The research methodology is a graphical method for solving the differential equation of train movement in the accepted range of changes in the mass of the composition of freight trains as a result of the implementation of which the authors obtained complete and reduced kinematic parameters of the movement of freight trains per one kilometer of the railway track and the parameters of the logistic indicators of the energy efficiency of these diesel locomotives in the form of tabular data, graphical dependencies, as well as regression equations with the subsequent development of nomograms for their calculation. The results of the study can be used by specialists of the Bukhara locomotive depot, which will allow them to develop recommendations for saving diesel fuel by the diesel locomotives under study, considering various conditions for organizing rail transportation of goods.
