Shanghai Metro

The Shanghai Metro is a rapid transit system in Shanghai, China, operating urban and suburban rail transit services to 13 of its 16 municipal districts (except Fengxian, Jinshan and Chongming) and to Huaqiao Town, Kunshan, Jiangsu Province. Opening in 1993 with full-scale construction extending back to 1986, Shanghai Metro is the third oldest rapid transit system in China, after the Beijing Subway and the Tianjin Metro. It has seen substantial growth, significantly during the years leading up to the 2010 Shanghai World Expo, and is still expanding, with its most recent expansions having opened in. It is the largest component of the Shanghai metropolitan rail transit network, together with the Shanghai Maglev Train, the Zhangjiang Tram and the China Railway-operated commuter rail services to Jinshan and to Nanhui New City in Pudong. The metro system is also heavily tied with other forms of public transport in Shanghai.

Currently, the Shanghai Metro system is the world's largest rapid transit system by route length  and second largest by number of stations after the New York City Subway, with 14 lines and 364 stations totaling 588 km. It also ranks second in the world by annual ridership after the Beijing Subway, with 3.068 billion rides delivered in 2015. The daily ridership record was set at 11.299 million on April 1, 2016, while over 10 million people use the system on an average workday.

On 16 October 2013, with the extension of Line 11 into Kunshan, Jiangsu province, Shanghai Metro became the first rapid transit system in China to provide cross-provincial service. Further plans to connect the Shanghai Metro with the metro systems of Suzhou and Wuxi are under active review. Ambitious expansion plans call for 25 Lines with over 1,000 km of length by 2025. Every location in the central area of Shanghai will be within 600 meters of a subway station.
