Recently, there was such a news online that the Chinese designer Chen Jianjun designed a stop train, which is shown in Figure 1. The train is below and the car is a pod. , Passengers first enter the pod from the carriage and the platform has a similar pod, as shown in Figure 2, where the passengers who are ready to get on the train are sitting in.
