With the rapid development of urban rail transit, the problem of energy consumption is drawing more and more attentions. Based on the utilization of regenerative braking energy among trains, this paper studies the energy-efficient operation method. We firstly propose an utilization strategy of regenerative energy among trains. Based on the proposed strategy, we set up the energy-saving model which optimizes the timetable and speed profile of trains simultaneous. Based on the particle swarm optimization algorithm, taking Beijing Yizhuang subway line and Changping subway line as examples of short section and long section for simulation, we verify the effectiveness of the proposed method. It is showed that the energy consumption of Yizhuang line and Changping line can be reduced by 3.2% and 5.5%, respectively, through improving the utilization of regenerative energy.
