The mitigation of delay propagation owing to excessive station dwell time is crucial for ensuring stable transport in a highly frequent urban train service. The precise departure time of the preceding train from the station is difficult to predict; however, control methods with predictions are effective in mitigating the delay of the following train. The train trajectory is generated using real-time continuous position information from the communication-based train control (CBTC) system, which can mitigate the delay propagation of the following train without predictions. In this study, a control method for mitigating delay propagation without predictions is proposed. Furthermore, introducing a finite-departure prediction for the preceding train can allow the following trains to avoid stops between stations. We numerically verify the effectiveness of reducing the delay time based on case studies with and without departure prediction. The results show that departure predictions effectively reduce headway and the duration of stops between stations for the following trains.
