Chongqing Rail Transit

The Loop line (coded as "Line 0") is a rapid transit loop line.[24] The northeastern section was opened on 28 December 2018. The southern section with the Egongyan Rail Transit Bridge opened on 30 December 2019.[25] Three major railway stations in Chongqing are also linked by this line: Chongqing North railway station, Shapingba railway station, and Chongqing West railway station.

Dongbu Park station of Loop line

Shapingba station of Line 1

Line 1 runs 16.4 km (10.2 mi) from Chaotianmen, in the central west, to Shapingba and then to Bishan with a total length of 44.5 km (27.7 mi). It is the first heavy-rail subway line in Chongqing and the second in Western China. The passenger capacity is 36,000 passengers per hour in each way. The line serves as the system's backbone connecting the densest areas including the main Central Business Districts of Jiefangbei, Lianglukou, Daping, and Shapingba. It is the first conventional subway, running in a deep-bored tunnel below Yuzhong and Shapingba Districts.

Line 1 has transfer interchange stations with Line 6 at Xiaoshizi and Line 2 at Jiaochangkou in Jiefangbei CBD and at Daping and Line 3 at Lianglukou, which is near Chongqing railway station in central Yuzhong. Line 1 is also transferable with the Loop Line at Shapingba, although out-of-station transfer is currently needed due to construction setbacks on the interchange channel and concourse connecting the two subway lines.

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 because of legal issues.[26] Work resumed from Chaotianmen to Shapingba on 9 June 2009, and a limited opening occurred on 28 July 2011.[27] Thales provided an operations control centre for the line. Line 1's color is red.

Line 2, a monorail line, runs 31.4 km (19.5 mi) and has 25 stations. It begins as a subway under downtown Jiefangbei, then runs west along the southern bank of Jialing River on an elevated line, and then turns south into the southwestern inner suburbs, looping back east, to terminate at Yudong, in Ba'nan District. It runs mostly elevated, but a 2.2 km (1.4 mi) section is underground, including three of its 18 stations in the Jiefangbei CBD and central Daping areas in the extremely-dense area of Yuzhong District. Line 2 runs through four administrative districts in the central city (Yuzhong, Jiulongpo, Dadukou, and Ba'nan). In 2010, Line 2 served 45 million passengers.[28] It also runs through Daping CBD, Yangjiaping CBD in Jiulongpo District, and Chongqing Zoo at. Most trains have four cars, and six-car trains began to operate in September 2012.[29] 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 because of overcrowding and increasing demand.[30] Line 2's color is green.

Line 3 is the longest and busiest monorail in the world. It runs from north to south and links the districts separated by the Yangtze (Chang Jiang) and the 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.[31] A southern extension, from Ertang to Yudong, opened on 28 December 2012.[32]

Most trains have six cars, more than on the older Line 2. The line started to equip eight-car trains in 2014, which are now in operation.[33] There are interchange stations in the Yuzhong district with Line 1, at Lianglukou (Caiyuanba Intercity Railway/Coach Station), and with Line 2, at Niujiaotuo. Line 3's color is indigo.

Line 4 is a rapid transit line.[34] In June 2018, debugging of the first segment of Phase I commenced.[35] The line began operating on 28 December that year. Line 4's color is orange.

Line 5 is a northeast–southwest heavy-rail line crossing the centre, and the line has opened its northern and southern sections of phase 1 and northern extension. It will connect Yubei, Jiangbei, Yuzhong, Jiulongpo, Shapingba and Dadukou districts. New six-car trains were introduced on the line. Line 5's color is light blue.

Line 6 is the second heavy-rail subway line of Chongqing. Opened on 28 September 2012, it connects Nan'an, Yuzhong, Jiangbei and Yubei districts in central Chongqing.

A northern branch, from Lijia to Wulukou, Beibei District, was opened on 31 December 2013,[36] 26.2 km (16.3 mi) long with five stations. Phase 1 of the Chayuan extension was opened in 2014. Thales provided an operations control centre for the line. Line 6's color is pink.

The first phase of Line 9 opened on 25 January 2022. Line 9's colour is crimson.

Xingke Ave. station of Line 9

Longtousi Park station of Line 10

The line serves the North Railway station and the airport terminals. The first phase (Liyuchi to Wangjiazhuang) opened on 28 December 2017, and the second phase will connect Yuzhong and Nan'an districts by crossing the Jialing and the Yangtze rivers. Two new bridges, Zengjiayan Jialing River Bridge and Nanjimen Rail Transit Bridge, are under construction for train services to the south. Line 10's color is purple.

CRT accepts Life & Transport Card (Chongqing Universal Card, released by Chongqing City Card Payment Co., Ltd.) and its compatible cards, released by partner companies in other cities of China. There is a 10% discount applied to the Regular Card if it is used on public transit in the city. The higher price is paid for transfers between the bus and the metro within 1 hour (not including metro-to-metro, according to the paying time). The Regular Card can be purchased at any CRT station, and a deposit can be recovered when the card is returned with its receipt. In addition the card can be used in many shops, cinemas, restaurants, etc. in Chongqing. The Students' Card and the Elders' Card can not be directly used on the metro since their monthly fee covers only buses unless a cash sub-account, which allows a 50% discount, is added to the cards for free at the service points.

All trips must be completed in 3 hours upon entering the fare-paid area, or the highest ticket price in the system will be charged in addition.[37]

Almost every station has accessible elevators and toilets, and almost every train has wheelchair locks. Only the oldest rolling stock and toilets of Line 2 are not fully accessible. In addition, many older interchange channels between lines are not designed with accessibility in mind, which means the disabled there must transfer via the main concourse.[38]

The trains on Line 10, which links Jiangbei Airport and Chongqing North railway station, are equipped with a luggage rack on each car.[39]

• 1946 plan: The Nationalist government made a plan of high-speed tram system.

The short-term plan, including Line 4 (West extension), Line 6 (Extension to Chongqing East Station), Lines 7, 15, 17, 24, 27 and Line 18 (Phase 2) was approved by NDRC.[54] Construction on several lines started in March 2021.[55] In April 2021, Lines 7 and 17 were redesigned from mostly elevated heavy monorails (similar to Lines 2 and 3) to conventional underground Type As metro lines akin to Lines 4, 5, 9 and 10.[56]
