Effect of Passenger Capacity Utilization Rate of a Train on Its Energy Cost Intensity and Passenger Transport Efficiency in View of Its Target Speed

Abstract

Based on simulations of the transports of a typically formed Chinese intercity passenger train hauled respectively by two representative types of locomotives on a certain railway line in China, this research analyzes the changes of the traction energy cost intensity and passenger transport efficiency of the train with varying its passenger capacity utilization rate and target speed. It is found that if the passenger capacity utilization rate of such a train is higher than 60.00 %, the effect of its passenger capacity utilization rate and target speed on its traction energy cost intensity and passenger transport efficiency is relatively small. If the passenger capacity utilization rate of the train is reduced from 40.00 %, the efficiencies of its traction energy cost and passenger transport both decrease obviously and such decreases are evidently affected by its target speed.
