| Popis: | Introduction. The paper considers the operation of interregional express trains operated by electric motor-car rolling stock whose route partly runs along non-electrified sections. These sections have electric trains hauled by a passenger diesel locomotive that also supplies electricity for the electric train auxiliary needs and the cabin microclimate system. The research is intended to compare the energy indicators of different modes of motor-car rolling stock operation on mixed routes with electrified and non-electrified sections.Materials and methods. The paper analyses the actual operational consumption of fuel and energy resources for a number of electrified and non-electrified sections, including electricity supply for auxiliary needs of electric motor-car rolling stock and the cabin microclimate system. The paper compares the energy consumption of these sections for different series of tractive rolling stock.Results. The author obtained data on the fuel consumption of a diesel locomotive with an electric train and a diesel train depending on the train composition and time of year, as well as indicators of specific fuel consumption for a diesel locomotive driving an electric train and a diesel train in negative temperature zones, i. e. with operating heating.Discussion and conclusion. The study shows that a diesel locomotive for electric train traction is less feasible than a diesel train in terms of energy consumption. The author gives a preliminary assessment of comparative characteristics of energy consumption under different modes of motor-car rolling stock operation on non-electrified sections. If these research data remain relevant, the next stage should include data processing from on-board registration systems and comparative testing. |
