The Chongqing Rail Transit (CRT) also known as Chongqing Metro, is a metro system in Chongqing, China that has been in operation since 2005. CRT serves transportation needs in the city's main business and entertainment downtown areas. It is one of only three urban-rail metro systems in operation in the west of China, the others being Chengdu Metro, and Xi'an Metro which opened in 2010 and 2011, respectively.

As of May 2013, CRT consists of four lines, with a total track length of 143 km. Lines 1 and 6 are conventional heavy-rail subways, while Lines 2 and 3 are monorails. Line 1 is the system's backbone connecting the most densely populated areas and Central Business Districts; Jiefangbei, Lianglukou, Daping, and Shapingba. Line 2 runs through three administrative districts in the central city (Yuzhong, Jiulongpo, and Dadukou). Line 6 runs from Jiangbei to Yubei. A network of up to 18 lines is planned.

At 72.0 km, the system's two monorail lines form the world's largest monorail network,[4] with the 55.5 km Line 3 being the world's longest single monorail line.[5][6]


The CRT is part of the central government's project to develop the Western regions and the Japan Bank for International Cooperation provided part of the funding.[7] Construction was carried out in cooperation between Changchun Railway Vehicles Co. Ltd. and Hitachi Monorail, using advanced Japanese monorail technology.[8] Construction on Line 2 began in 1999, and it was officially opened in June 2005 from Jiaochangkou (Jiefangbei CBD) to Dongwuyuan Chongqing Zoo.

Timelapse of the Chongqing Metro.

CRT is a unique metro system in China in that a significant number of lines use heavy monorail technology. In a hilly, multiple-river city it is not feasible to construct an all heavy-rail tunnel system given the depths of some many of the stations. For this reason, only two lines are planned to be heavy rail, the others straddle-beam monorails using heavy vehicles.

Line 1 is the first conventional subway running in a deep bored tunnel below Yuzhong and Shapingba Districts. The only other conventional subway is Line 6, which connects the main central business districts of Nanping in Nan'an District and Jiangbei's Guanyinqiao CBD and New City CBD to Jiefangbei CBD.

The monorail vehicles with strong climbing capabilities and have heavy rail capacity, which can transport 30,000 passengers per hour per direction, invaluable in the densely populated but hilly city. Line 2 is for the most part elevated above streets, although a 2.2 km section is underground, including three of its 18 stations in the Jeifangbei CBD and Daping downtown areas in hyper-dense populated area of Yuzhong District. In 2010, Line 2 served 45 million passengers.[3]

To keep up with demand, construction is under way on extensions to Line 1, Line 2, Line 3, and Line 6, whose primary route is currently under trial. With the opening of Line 3 and Line 6 in 2012, all of the core urban area will be accessible by CRT.

Line 1[edit]

Line 1 runs 16.4 km from Chaotianmen in downtown west to Shapingba, and eventually to Shuangbei with a length of 22.41 km. It is the first heavy-rail subway line, the second in Western China. Passenger capacity is 36,000 passengers/hour/direction.

In 1992, the Chongqing government signed a Build-Operate-Transfer agreement with a Hong Kong company and provided the land for the project, but work ceased in 1997 due to legal issues.[citation needed] Work resumed from Chaotianmen to Shapingba on 9 June 2007, and opened to limited operation on July 28.[9] An extension from Shapingba to University Town began in 2009 and was scheduled to open in 2013.

Line 1 has 14 stations, including interchange stations with Line 2 at Jiaochangkou in Jeifangbei CBD and at Daping and with Line 3 at Lianglukou, near the Chongqing Rail Station in the Caiyuanba section of central Yuzhong.

Line 2[edit]

Line 2, a monorail line, runs 19.15 km and services 18 stations It begins as a subway under downtown Jeifangbei, then runs west along the southern bank of the Jialing River on an elevated line, then turns south into the south-western inner suburbs, terminating in Dadukou district. It also runs through Daping CBD and Yingjiaping CBD in Jiulongpo District and the Chongqing City Zoo at Dongwuyuan Station. A 6.2-kilometer extension into Ba'nan is under construction. Most trains consist of four carriages, and six-carriage trains began to operate in September 2012.[10] In 2013, eight-car trains are being considered due to overcrowding and increasing demand.[11]

Line 3[edit]

Line 3 runs from north to south, linking the districts separated by the Yangtze (Chang Jiang) and Jialing rivers. The initial segment from Lianglukou to Yuanyang (18 stations, 17.5 km) opened on September 29, 2011, with a northern extension from Yuanyang to Jiangbei Airport opening on December 30, 2011[12] and a southern extension from Ertang to Yudong on December 28, 2012.[13]

Most trains consist of six carriages, bigger than on the older Line 2, expected to upgrade to eight-car trains by 2014.[14] Currently 8 car trains are undergoing testing.[15] There are interchange stations in central Yuzhong district with Line 1 at Lianglukou (Caiyuanba Intercity Rail/Bus Station), and with Line 2 at Niujiaotuo.

Line 6[edit]

Line 6 is the second heavy-rail subway and extensions at both ends are under construction. Opened on 28 September 2012 it connects Nan'an, Yuzhong, and Jiangbei districts in central Chongqing. A northern branch line from Lijia to Wulukou, Beibei district was opened on 31 December 2013,[16] 26.2 km long with five stations.

Network expansion[edit]

CRT is expected to have six lines criss-crossing the urban districts by 2015, and a loop line connecting them.[17] However, in addition to the extensions to Lines 1, 2 and 3 only one line was under construction in mid 2011. Phase 1 for the Circle Line was expected to commence construction by the end of October 2013, linking Chongqing West Railway Station and Shanghao in Nan'an District with 22 underground stations, by 2018.[18] Construction of Lines 4 and 5 commenced on December 5, 2013 to be completed by 2017, with Line 10 expected to start construction early in 2014.[19]
