Comparative analysis of the degree of influence of factors on the speed of trains (using the example of Uzbek railways)

Abstract

The main objective of the work is to conduct a comparative analysis of the impact of the main factors on train speeds on the normative and implemented train traffic schedule indicators. This was done using systematic, analytical, factor and tabular analyses. The train traffic speeds on the railway sections of the regional railway nodes of “UTY” JSC were systematically analyzed for the period 2011-2022, and as a result, the main factors that significantly negatively affect the actual implementation of the established normative speed values (replacement of train locomotives, the number of seasonal freight trains, stopping times at stations along the route, the number of seasonal passenger trains) were identified. The shares of the degree of influence of the identified main factors on the speed of freight trains on the railway sections were determined according to the criteria of weak, medium and strong. It was determined that the share of the main factors influencing the speed of freight trains on the railway sections under the jurisdiction of “UTY” JSC is weak - 32%, medium - 44% and strong - 24%. The method of systematic analysis of factors makes it possible to reasonably establish the values of train speeds in the production process and predict them on a daily, quarterly and annual basis.
