When the train adopts traditional braking method in transit, due to the transmission of brake-wave with time delay, the impact among the wagons is bound to happen. In this case, the goods will traverse or scurry out from the wagons, even cause the train derailment accident. In this paper, the characteristics of the present braking method and the forces in goods were analyzed. The braking method for control brake with wire was put forward in order to achieve the purpose of train synchronous braking.
