Abstract: This paper investigates the percentage of freight and passenger transportation by railway over the past 14 years, playing a vital role in the social and economic development of Mongolia. To address the average idleness of wagons per one operation of freight and overcome barriers to achieving transportation volume and railway development goals by 2030, this study investigates the unloading dynamics at all stations of the UB Railway JVC over the past decade. The study examines the efficiency of shunting locomotives utilized in disassembling and placing unloaded wagons on branch tracks at stations with high unloading demand. Additionally, it conducts operational analysis by marshalling trains based on destination stations, cargo receivers, and branch line zoning to explore the potential reduction of local wagon idle time, impacting the average idle time per one freight operation.
Keywords: transported freight, local wagons, shunting locomotives, branch tracks
