An overview of modern trends in updating shunting locomotives, which are based on the installation of on-board energy storage devices, multi-diesel propulsion power plants, and power plants operated on hydrogen energy sources, was carried out. The necessity to take into account the operating conditions of a shunting diesel locomotive when choosing an upgrade option is shown. The operation modes of shunting diesel locomotives during shunting operations at the Козятин-I freight station during three shifts were considered. By analyzing the data of the БІС-Р onboard system and processing the route sheets, the parameters of the operating modes were determined. Calculations of diesel engine power utilization indicators were performed, according to which it was determined that the full use of the installed diesel generator power is 7.5...8.4%, and the maximum diesel power recorded under the studied operating conditions is about 50%. The duration of work with traction loads is 49.5...68.8% of the shift time. The longest - 55...60% of the total duration of work under traction - are modes with a power of 0...50 kW. The duration of work without load is 18.1...36.9% of the duration of the shift. The shunting work performed is related to the formation and disassembly of trains, including the use of a sorting slide, as a result of which the traction power transmission operates with a low efficiency. In order to reduce the consumption of fuel and energy resources when performing shunting work, it is necessary to update the fleet of locomotives for shunting work, the characteristics of which are adapted to the operating modes. Key words: hybrid locomotive, modernization, shunting, energy efficiency, energy storage

The paper considers the modes of operation of shunting diesel locomotives ČME3 when performing traction tasks at the service areas of the locomotive depot Koziatyn. A mathematical model of train movement with a ČME3 diesel locomotive has been developed, which has been used to solve a series of traction problems. It was found that the operating modes of a diesel engine are most influenced by the profile of the track section. It is determined that when moving from the Koziatyn station, the relative duration of the traction mode is 14...39% of the total movement time. When moving in the direction of the Koziatyn station, the relative duration of the traction mode is 28...90%. In the traction mode, the diesel engine operates at rated power. For the examined sections of the movement, we evaluated the diesel fuel consumption for a serial diesel locomotive, a diesel locomotive with a modern diesel engine, and a battery locomotive charged from an onboard diesel generator set. It has been determined that a diesel locomotive with a modern diesel engine consumes 18...22% less fuel than a standard diesel locomotive. In the case of a battery locomotive, fuel consumption can be either lower or higher compared to a diesel locomotive with a modern diesel engine. At the same time, the accumulation of energy in the onboard energy storage device during electrodynamic braking and its use in traction modes helps to reduce fuel consumption.
