Reduction of the traction energy and increasing the reused regenerative energy are two main ways for saving energy in rail systems, which are related to the driving strategy as well as the train timetable. To minimise the net energy consumption (i.e., the difference between the traction energy and the reused regenerative energy), an integrated optimisation approach is an efficient way, in which the driving strategy and the train timetable are jointly optimised. This chapter will focus on this optimisation in the metro system, where homogeneous trains are operated on a double-track line with up and down directions. Firstly, the mathematical models are formulated to calculate the amount of traction energy and reused regenerative braking energy. Then, two approaches to reduce the net energy consumption will be introduced for metro line. In the first approach, the departure times of trains are synchronized to the arrival time of regenerative braking trains to reuse the regenerative braking energy efficiently. The second approach jointly optimises the station arrival/departure times and the traction/braking regimes between the stations, to improve the energy-saving. Both approaches are verified by examples based on real world data of metro lines.
