The Shanghai Metro is the urban rapid transit system of China's largest city, Shanghai. The system incorporates both subway and light railway lines. It opened in 1995, making Shanghai the third city in Mainland China, after Beijing and Tianjin, to have a subway. Since then, the Shanghai Metro has become one of the newest and fastest-growing rapid transit systems in the world. Today, there are eight metro lines, 162 stations and 225 km of tracks in operation, making it the longest network in China, exceeding even the Hong Kong MTR. Daily ridership averaged 3.065 million in 2008 and set a record of 4.307 million on December 31, 2008.
