Chengdu Metro, commonly known as Metro in Chengdu, (Chinese: 成都地铁; pinyin: Chéngdū dìtiě) is a metro system in Chengdu, the capital city of Sichuan Province in China. It has two lines: Line 1, which was constructed between December 2005 and 2010 (trial operation in March 2010 and formal opening on 27 September 2010); and Line 2, which began operations on in September, 2012. It is operated by Chengdu Metro Limited Liability Company. On September 27, 2010 Chengdu Metro was officially opened, making it the first all-Heavy Rail metro system in western China.[2]

Chengdu is in a tie with Shenyang as the 7th major city in Chinese Mainland to have a functioning subway system, after Beijing, Guangzhou, Nanjing, Shanghai, Shenzhen and Tianjin.[3]

The Chengdu Metro currently consists of two parts:The Chengdu Metro and the City Railway. It is China's first joint venture between a local government and China's national rail operator. Both the Chengdu Metro and Ministry of Railways will work together in building metro lines and high speed commuter rail lines.[4]

Line 1

Luomashi Station

The construction of the first phase of Line 1, costing 7 billion yuan, will change the city. One of the metro planners said the construction of the metro will change the layout of residential quarters in the city, with residential areas moving out to the suburbs.[13] 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.[14]

Line 2

Line 2 is a crosstown northwest-southeast trunk route. It serves the Chengdu East Railway Station. Line 2 began operation on September 16, 2012.[15]

Rolling stock and technology

There will be 22 B size sets of three cars each when the line opens, made by CSR. The trains will be air-conditioned and can hold up to a maximum of 1,200 people. The cars will be 2.8m wide and 19m long. In the future, trains will be expanded to five cars. The rolling stock's average train speed will be 35 km/h and its maximum speed will be 80 km/h. The metro system will be equipped with Automatic Train Protection, Automatic Train Control, Automatic Train Stop and Automatic Train Operation. Fire alarms, on-train/track systems, and automatic fare collection systems will also be installed. A minimum curve radius of 400m will be used where possible, though some restricted areas will have a curve radius of 300m. The maximum gradient will be 35% and the railway tracks will be laid to standard gauge (1435mm) using 60 kg/m rail, allowing a maximum speed of 80 km/h. The power supply will be 750V DC with third rail collection and running rail return.[16]

In April 2011, a further order was announced for trains from CSR, taking the total to 354 units.[17]

Network expansion

Seven lines are planned to be constructed over the next thirty years and five have been planned so far, with all around the city centre. When the whole of Line 1 is completed, it will have a length of 31.6 km with 22.44 km of underground tracks and 9.16 km of tracks at either ground level or elevated with 23 stations. There will be a depot at Huayang, two main substations, ten traction substations and one control centre. Line 1 will interchange with Chengdu Railway Station and Chengdu South Railway Stations.[16]

Lines under construction

Line 3,4 and Line 1 Phase 2 are currently under construction and expected to be finished before 2015.[18] Line 7 is expected to start construction before the end of 2012 with a 2015 target completion date.[19] In 2020 is expected to Chengdu will build about 291 km of subway lines.[20]
