Chengdu Metro (branded as metro) is the local mass rapid train transportation system in Chengdu, the capital of Sichuan Province, China. Currently, the system has five lines in operation. 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);[3] 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. Commuter rail lines such as the Chengdu–Dujiangyan Intercity Railway are operated by Chengdu City Commuter Railway Limited Liability Company. 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 commuter rail lines.[4] A light rail system northwest of Chengdu began construction at October 2015, and will open to public in 2017. There are currently over 350km of subway lines under construction.[5]

Line 1[edit]

Luomashi Station

The first phase of Line 1 cost 7 billion yuan to construct.[16] 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.[17]

Line 2[edit]

Line 2 is a crosstown northwest-southeast trunk route. It serves the Chengdu East Railway Station. Line 2 began operation on 16 September 2012.[18]

Line 3[edit]

Line 3 is a crosstown northeast-southwest trunk route. It started operation on 31 July 2016.

Line 4[edit]

Line 4 is a crosstown east-west trunk route, serving the Chengdu West Railway Station. It started operation on 26 December 2015.

Line 10[edit]

Line 10 is an express route, serving Chengdu Shuangliu International Airport. It started operation on 6 September 2017.

Rolling stock and technology[edit]

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%[clarification needed], and the railway tracks will be laid to standard gauge (1435mm) using 60 kg/m rail, allowing a maximum speed of 80 km/h. [19]

All Chengdu Metro lines in operation run on 1,500 V DC supplied by overhead lines.[20][21][22][23]

In April 2011, a further order was announced for trains from CSR, taking the total to 354 units.[24]

Network expansion[edit]

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 reached 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 Station.[19]

Lines under construction[edit]

Line 7 is expected to start construction before the end of 2012 with a 2015 target completion date, but was pushed back to 2017.[25] In 2020, it is expected that Chengdu will build about 291 km of subway lines.[26] In 2017 the first phases Lines 8, 9, 11, 17 and Line 10 Phase 2 will start construction being the length of subway under construction in Chengdu to 400km.[27]
