With a total length of 33.6 kilometers, Shanghai Metro Line 13 is a northwest-southeast underground diameter line that runs through the center and stretches over eight districts of the city. As an important artery of Shanghai's metro transportation network, Line 13 once served as an Expo Line that linked the Expo Park with the outside during 2010 Shanghai World Expo. The design team boldly selected symbolic bright colors for all stations of the line and printed the images of Expo pavilions on the walls, so as to commemorate the special event. To meet the overal design requirements, the stations of Line 13 used Luxalon Baffle ceilings in bright red, yellow and green colors, which create an energetic yet neat and simple space.
