Line 3 is a north-south line of the Shanghai Metro network. Its rolling stock carry a bright yellow colour belt to differentiate them from Line 4 trains which share a portion of its track. Unlike the majority of the lines in the Shanghai Metro system, Line 3 is primarily elevated, entirely above ground except for its Tieli Road Station, located at the entrance to Baosteel Group Corporation. The line runs from Jiangyang North Road in the north to Shanghai South Railway Station in the southwest of the city, where it meets Line 1. While Line 1 goes straight through the city center, Line 3 roughly follows the Inner Ring Road around the city from Caoxi Road to Zhongtan Road (where it turns eastwards to join the route of the Shanghai–Nanjing Railway). The line is colored yellow on system maps.
