Chengdu Metro
Encyclopedia
Chengdu Metro, commonly known as Metro in Chengdu, is a metro
system in Chengdu
, the capital city of Sichuan Province
in China
. It has one line, Line 1, which was constructed between December 2005 and 2010 (trial operation in March 2010 and formal opening on 27 September 2010). 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.
Chengdu is in a tie with Shenyang
as the 9th major city in the People's Republic of China to have a functioning metro system, after Beijing
, Chongqing
, Guangzhou
, Nanjing
, Shanghai
, Shenzhen
, Tianjin
and Hong Kong.
, 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. 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.

. 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.

Rolling stock and technology
There will be 22 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.
