Chongqing Rail Transit Lines 2 & 3

Line 2
Line 2, a monorail line, runs 31.3 km (19.4 mi) and services 25 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, looping back east to terminate at Yudong in Ba'nan. It also runs through Daping CBD and Yingjiaping CBD in Jiulongpo District and the Chongqing City Zoo at Dongwuyuan Station. Most trains consist of four carriages, and six-carriage trains began to operate in September 2012. Line 2 is the first rapid transit line to open in the Interior West of China (in 2005). In 2013, six-car trains are being implemented due to overcrowding and increasing demand.

Line 3
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 (10.9 mi)) opened on 29 September 2011, with a northern extension from Yuanyang to Jiangbei Airport opening on 30 December 2011 and a southern extension from Ertang to Yudong on 28 December 2012.

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