The brake cylinder charging time is an important parameter in the air brake system and it affects train performance such as braking distance, coupler force, and car acceleration. For the discrepancy of brake cylinder charging time between the rapid freight car and the general-purpose freight car, the longitudinal impulse in the mixed formation train is more complicated. This paper proposed a mixed formation train model with the rapid freight car air brake system and the general-purpose freight car air brake system. The influence of the brake cylinder charging time difference on coupler force of mixed train was predicted. The results show that due to the difference of brake cylinder charging time, the marshaling position of rapid freight cars affects the coupler forc, and the rapid freight car located in the rear of the train is preferable. The longitudinal impulse of the mixed train with rapid freight cars located in the rear decreases with rapid freight car brake cylinder charging time reduction.
