Chengdu Metro is the local mass rapid train transportation system in Chengdu, the capital of Sichuan Province, China. The system has four lines. Line 1 was constructed between December 2005 and 2010, and opened at Sep 27th, making it the first heavy-rail metro line in south and west China. (Chongqing Rail Transit Line 2 opened first in 2005 but is Heavy-Monorail); and Line 2 began operations in September 2012. Line 4 opened to public at the end of December 2015, while Line 3 opened in July 2016. Metro lines are operated by Chengdu Metro Limited Liability Company. And city commuting train lines including Chengdupu Line and Chengpeng Line are operated by Chengdu City Commuting Railway Limited Liability Company.

The Chengdu Metro System consists of three parts: the Metro and the City Railway, as well as the Light Rail Train. It is China's first joint venture between a local government and China's national rail operator. The city and the Ministry of Railways worked together in building metro lines and high speed commuting rail lines. The light rail began construction at October 2015, and will open to public in 2017.

There will be five lines constructed in the first phase, covering 126 km with 116 stations including 11 interchange stations. Line 1 has 17 stations at along the 18.50 kilometre route, starting at Shengxian Lake and ending at Century City. Line 2 has 26 stations along the 31.20 kilometre route, starting at Xipu and ending at Chengdu Institute of Administration.

The first phase of Line 1 cost 7 billion yuan to construct. A natural ventilation system has been used in the construction of the underground section of Line 1 on the subway system from Southern Third Ring Road to Chengdu New Exhibition and Convention Center. Square ventilation units are built every 30m along the subway top to allow fresh air from the ground enter the construction site underground. The method is used in subway construction in other countries as it cuts the construction cost and it saves energy. The subway system is the first in China to adopt such a ventilation system during construction. Chengdu Metro is planning to set up a section for subway fire control and introduce the latest fire fighting technologies and vehicles.
