Shanghai is home to world's newest subway system. There are currently 11 lines running in the city including the Shanghai Maglev. The system includes both subway and light rail lines running on elevated tracks.
With the 2010 Expo slated to be held in Shanghai, a large expansion of the current subway system is under way.
Line 1 (red) for example runs north-south. It is convenient for the French Concession.
Subway stations can still be a bit spread out, and using the system requires a fair bit of walking. However, for the price and efficiency, it is a great way to get around Shanghai.
Trains run from approximately 5.30am to between 10 and 11pm.
Both the trains and the stations are quite clean. Signs and carriage announcements are in Chinese and English. Metro stations have a red "M" sign outside their entrances.
Fares cost from 3RMB to 8RMB, depending upon how far you are riding. The Shanghai Public Transportation Card (SPTC) can be purchased and recharged at metro stations and convenience stores.
Keep your ticket. You will need to have it if you transfer.
Construction is under way for several other lines in the lead up to the 2010 World Expo.
Line 2 (green) will join the city's two airports: Pudong and Hongqiao.
Line 7 is scheduled to be extended north to Shanghai University and to the southeast to Pudong to the planned East Shanghai Railway station.
Line 8 will be extended to Sanlin Town.
Line 9 (Shensong Line) will run through the city center to Pudong.
Line 10 will be the new east-west line.
Line 13 is slated to open in time for the World Expo in 2010, and it will serve that area of town.
