FIELD: machine building.
SUBSTANCE: invention relates to the field of machine building. Locomotives energy efficiency is monitored. Determining two energy efficiency indicators, such as average operating efficiency of locomotive and deviation of actual consumption of energy resources from design flow rate. Locomotive operating average efficiency is determined on the basis of data from on-board recording systems of motion parameters as ratio of operation to overcome forces of train resistance to spent energy resources. Deviation of actual consumption of energy resources from design flow rate is obtained at standard value of locomotive efficiency. In addition, relative average operating efficiency is determined, which is equal to ratio of average operating efficiency to rated efficiency. In addition, traction average operating efficiency is determined.
EFFECT: higher reliability and reliability of influence on energy efficiency of various factors associated with transportation process.
