The railway traction power network supplies the electricity to electric trains. The traction power network modelling plays a significant role in evaluating the railway system energy flow and validating the energy-efficient train operations. This chapter presents the development of an energy evaluation simulation of electric railway systems. The train movement model and railway power network model are integrated into the simulator. This energy simulator is able to calculate the energy flow of the whole system according to multiple-train driving controls and timetables. Based on the power network model, this chapter analyses the energy consumption of railway systems with regenerating trains, including the energy supplied by substations, used in power transmission networks, consumed by monitoring trains, and regenerated by braking trains. A case study of Beijing Yizhuang Subway Line has been conducted which indicates that the available regenerative braking energy and total substation energy consumption vary with timetables. The difference in energy consumption between the different headways is up to 35%, suggesting the importance of timetable optimisation on energy consumption. The comparison case study indicates that the substation energy is reduced by around 38.6% with system optimised operations. The efficiency of using regenerative braking energy is improved from 80.6 to 95.5%.
