With the gradual formation of the development pattern of multi-system and network of regional rail transit, the operation mode between each system of regional rail transit is gradually moving from single to collaborative. In this paper, we focus on the dynamic optimization of train operation diagram for the cooperative development of multi-system regional rail transit, take the transfer process between railways and urban rail transit as the research object, take the minimum waiting time of passengers as the optimization objective, construct an optimization model with the constraints of the departure time and the interval of urban rail transit trains, solve the model by using the DQN optimization algorithm, and design the case study to verify the model. The results of the case study show that the total waiting time of passengers is 156.48 h, which is better than the total waiting time of 174.65 h under the equal interval, and the optimization rate is 10.4%, which proves the validity of the model, by optimizing the departure interval of the train schedule under the conditions of dynamic passenger flow through real-time decision-making.
