The trains arrive below the waiting areas, which are not interrupted by the structure itself, which is roughly divided into three levels. The mid-level contains the station platforms, at the same rough height as ground level, and contains thirteen tracks and six passenger platforms. The VIP waiting section and the Public Security Office is also on this level. In addition the mid-level has direct access to the northern and southern squares. The upper level is the departure level. With a circumference of over 800 meters, the waiting area can fit over 10,000 passengers at any given time. Passenger tickets are also validated in this area. The lower level is the arrivals level, which contains various tunnels to exit the station and the waiting area of the Line 1 and Line 3 in the Shanghai Metro system. In the future it will also contain a transfer tunnel to the newly opened L1 Line as well as access to long-distance and tourist buses. The underground level of the North and South Squares has various commercial establishments and a parking lot.
