context_page_description: Line 4 is a loop line of the Shanghai Metro network. Its rolling stock carry a bright violet colour belt to differentiate them from Line 3 trains which share a portion of its track. To determine the direction of travel, the line that travels counter-clockwise is called the Outer Loop, while the other line is known as the Inner Loop. Although it is a loop line, trains returning to the depot use Yishan Road as a terminal to let all passengers disembark. The first segment of the line between Damuqiao Road and Lancun Road opened on December 31, 2005. The remainder of the line opened on December 29, 2007. The line is colored purple on system maps.
