Abstract: This article discusses comparative statistical data analysis of energy consumption by EP20, EP2K, EP1M passenger electric locomotives. On the basis of primary data, it has been established that the highest specific energy consumption is that of passenger electric locomotives with railroad trains of double-deck passenger wagons. Comparison of specific energy consumptions by EP20 and EP2K DC electric locomotives has demonstrated that the EP20 electric locomotives on flat terrain are characterized by significantly higher specific energy consumption in comparison with that of EP2K electric locomotives. Comparison of specific energy consumptions by EP20 and EP1M AC electric locomotives with single type passenger wagons has demonstrated that the EP20 electric locomotives on flat terrain are characterized by nearly the same energy consumption as that of EP1M electric locomotives. Analysis of load upon running special passenger trains for EP20 electric locomotive along Moscow–Adler line has revealed underload of electric locomotive which leads to decrease in its efficiency and, as a consequence, excessive energy consumption.
