Chongqing Rail Transit

Public transport in Chongqing consists of metro, intercity railway, a ubiquitous bus system and the world's largest monorail network.

According to the Chongqing Municipal Government's ambitious plan in May 2007, Chongqing is investing 150 billion RMB over 13 years to finish a system that combines underground metro lines with heavy monorail.

As of 2017, four metro lines, the 14 km (8.7 mi) long CRT Line 1, a conventional subway, and the 19 km (12 mi) long heavy monorail CRT Line 2 (through Phase II), Line 3, a heavy monorail connects the airport and the southern part of downtown. Line 6, runs between Beibei, a district in the city's far north to downtown. Line 5 opened in late 2017.

By 2020 CRT will consist of 6 lines and 1 loop line resulting in 363.5 km (225.9 mi) of road and railway to the existing transportation infrastructure and 93 new metro stations will be added to the 111 stations that are already in place.

By 2050, Chongqing will have as many as 18 lines that are planned to be in operation.
