What do you mean by the train shaking?

When the train passes somewhere, passengers will feel slightly unstable and shaky. Train shaking refers to when the train is running. When the train passes through a certain place, passengers will feel slightly unstable and shaking. This situation is called "rocking the car". This situation is mainly due to the slight unevenness of the line, which leads to the uneven track of the train, thus causing the train to shake. When this situation is found, it should be reported to the nearest station in time, and the following trains and adjacent trains should be informed to pay attention to the operation.
