Assessment of the effect of train traction by locomotives of different types on the quality indicators of the train schedule

The precinct and technical speed of freight trains is one of the main parameters of railway transport characterizing qualitative indicators. The higher the local and technical speed, the better the quality indicators of railway transport, the higher the speed of cargo delivery to the addresses. These speeds directly depend on the distance between stations and the time of their passage. The types of electric locomotives are one of the main factors determining the travel time and energy consumption of trains moving along the site. The differentiated accounting of inter-station runs in the train schedule is based on traction calculations. This article analyzes the regulatory timetable of the trains of the “Tukimachi – Akhangaran” section of Uzbekistan Railways JSC and develops a methodology for determining the travel time of trains moving on the section for the 3VL80r electric locomotive based on traction calculations. Based on the developed methodology, the influence of the time of inter-station runs under traction conditions by locomotives of various brands on the site and technical speed of trains on the railway section was estimated.
