The huge energy consumption of rail transit and the study of train energy saving operation have important theoretical and practical values. From energy saving point of view, the energy conversion mechanism in train operation process is analyzed, and the minimum energy consumption optimization model of single train, multi-train energy saving optimization model and multi-objective train delay optimization control model are established. According to the complexity of the model itself and its constraints, Based on the “simulation optimization” solution of the improved cuckoo optimization algorithm and dynamic search method, the problem of train energy saving operation decision-making is solved and compared with other similar algorithms, the superiority of the proposed method is expounded. The optimal energy-saving operation control strategy of train under different operating conditions is obtained, and the optimal speed distance curve of each train running is determined. The result is in line with the actual situation. The search algorithm of the improved algorithm is more efficient, and the research ideas and models have certain reference value for the energy-saving operation and operation of the train. The proposed solution to the complex optimization model is reasonable and effective, and has a good reference value.
