To obtain an operation curve of a train with minimum energy-consumption and improve the utilization of regenerative braking energy without changing equipment and infrastructure, this paper proposes a new optimization method of energy-saving for a train based on an improved chicken swarm optimization algorithm after analyzing the calculation method of energy-consumption for a train and improving the chicken swarm optimization algorithm. On this basis, this paper establishes an optimization model of energy-saving for a train by taking minimum energy-consumption, accurate stopping and punctuality as optimization objectives, and solves the model with the improved chicken swarm optimization algorithm. Finally, a simulation analysis for the method proposed in this paper is performed by using MATLAB software with the running parameters of Nanning metro line 1 in China. The results of the simulation analysis show that the method proposed in this paper is effective in solving the optimization problem of train energy-saving.
