Line](https://bliptext.com/articles/loop-line-chongqing-rail-transit) at [Shapingba](https://bliptext.com/articles/shapingba-station), although out-of-station transfer is currently needed due to construction setbacks on the interchange channel and concourse connecting the two subway lines.\nIn 1992, the Chongqing government signed a [Build-Operate-Transfer](https://bliptext.com/articles/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.\nWork resumed from Chaotianmen to Shapingba on 9 June 2009, and a limited opening occurred on 28 July 2011.\n[Thales](https://bliptext.com/articles/thales-group) provided an [operations control centre](https://bliptext.com/articles/control-room) for the line.\nLine 1's color is **red**.\n\n## Line 2\nLine 2, a [monorail](https://bliptext.com/articles/monorail) line, runs 31.4 km and has 25 stations.\nIt begins as a subway under downtown Jiefangbei, then runs west along the southern bank of [Jialing River](https://bliptext.com/articles/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](https://bliptext.com/articles/ba-nan-district-chongqing).\nIt runs mostly elevated, but a 2.2 km section is underground, including three of its 18 stations in the [Jiefangbei CBD](https://bliptext.com/articles/jiefangbei-cbd) and central Daping areas in the extremely-dense area of Yuzhong District.\n[Line 2](https://bliptext.com/articles/line-2-chongqing-rail-transit) runs through four administrative districts in the central city

station](https://bliptext.com/articles/chongqing-north-railway-station) and the airport terminals.\nThe 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.\nTwo new bridges, Zengjiayan Jialing River Bridge and Nanjimen Rail Transit Bridge, are under construction for train services to the south.\nLine 10's color is **purple**.\n\n## Jiangtiao line\nJiangtiao line is a suburban [rapid transit](https://bliptext.com/articles/rapid-transit) line connecting [Jiangjin District](https://bliptext.com/articles/jiangjin-district) with the metropolitan area.\nThere will be [through service](https://bliptext.com/articles/through-service) between Line 5 and Jiangtiao line in the future.\nJiangtiao line's color is **blue**.\n\n# Ticketing\n\n## Transport cards\nCRT accepts [Life & Transport Card](https://bliptext.com/articles/life-transport-card) (Chongqing Universal Card, released by [Chongqing City Card Payment Co., Ltd.](https://bliptext.com/articles/chongqing-city-card-payment-co-ltd)) and its compatible cards, released by partner companies in other cities of China.\nThere is a 10% discount applied to the Regular Card if it is used on public transit in the city.\nThe 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).\nThe Regular Card can be purchased at any CRT station, and a deposit can be recovered when the card is returned with its receipt.\nIn addition the card can be used in many shops, cinemas, restaurants, etc. in Chongqing.\nThe 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.\n\n## Time limit\nAll 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.\n\n# Operation\nDuring times of heavy use like for major events, CRT may close some stations to avoid overcrowding.\nIn 2018, CRT closed Xiaoshizi, Jiaochangkou, Qixinggang, Lianglukou, Xiaolongkan, and Shapingba stations of Line 1; Jiaochangkou and Linjiangmen stations of Line 2; Lianglukou, Huaxinjie, Guanyinqiao, and Hongqihegou stations of Line 3; Shangxinjie, Xiaoshizi, Grand Theater, Jiangbeicheng, and Hongqihegou stations of Line 6 after 20:00 on Christmas Eve, Christmas Day, after 19:00 on New Year's Eve.\nAnd they also closed Shapingba and Shangxinjie stations of Loop line after 19:00 on New Year's Eve.\nFrom 9 to 12 November 2018, they closed Grand Theater and Jiangbeicheng stations from 10:00 to 15:00 because of heavy use during Flower Expo; from 1 to 7 November 2019, they closed Grand Theater and Jiangbeicheng stations since 10:00 till 16:00 because of heavy use during Flower Expo.\n\n## Accessibility\nAlmost every station has accessible elevators and toilets, and almost every train has wheelchair locks.\nOnly the oldest rolling stock and toilets of Line 2 are not fully accessible.\nIn 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.\n\n## Luggage rack\nThe trains on Line 10, which links [Jiangbei Airport](https://bliptext.com/articles/jiangbei-airport) and [Chongqing North railway station](https://bliptext.com/articles/chongqing-north-railway-station), are equipped with a luggage rack on each car.\n\n# History\nThe CRT is part of the central government's project to [develop the Western regions](https://bliptext.com/articles/china-western-development).\nThe [Japan Bank for International Cooperation](https://bliptext.com/articles/japan-bank-for-international-cooperation) provided some of the funding.\nConstruction was carried out, with co-operation between [Changchun Railway Vehicles Co.

Additionally, Chongqing Rail Transit system has numerous [double-deck bridges](https://bliptext.com/articles/double-deck-bridge) carrying vehicle and metro traffic, such as the [Chaotianmen Bridge](https://bliptext.com/articles/chaotianmen-bridge), which is the world's longest [arch bridge](https://bliptext.com/articles/arch-bridge).\n\n# Network\n# [800px | upload.wikimedia.org/wikipedia/commons/c/cc/Chongqing///Rail///Transit///system///map///201812///ver///20190126.png]\n\n## Loop line\nThe Loop line (coded as \"Line 0\") is a rapid transit [loop](https://bliptext.com/articles/circle-route) line.\nThe northeastern section was opened on 28 December 2018.\nThe southern section with the [Egongyan Rail Transit Bridge](https://bliptext.com/articles/egongyan-rail-transit-bridge) opened on 30 December 2019.\nThree major railway stations in Chongqing are also linked by this line: [Chongqing North railway station](https://bliptext.com/articles/chongqing-north-railway-station), [Shapingba railway station](https://bliptext.com/articles/shapingba-railway-station), and [Chongqing West railway station](https://bliptext.com/articles/chongqing-west-railway-station).\nLoop Line's color is **yellow**.\n\n## Line 1\nLine 1 runs 16.4 km from Chaotianmen, in the central west, to Shapingba and then to Bishan with a total length of 44.5 km. It is the first [heavy-rail subway](https://bliptext.com/articles/rapid-transit) line in Chongqing and the second in Western China.\nThe passenger capacity is 36,000 passengers per hour in each way.\nThe line serves as the system's backbone connecting the densest areas including the main Central Business Districts of [Jiefangbei](https://bliptext.com/articles/jiefangbei-cbd), Lianglukou, Daping, and Shapingba.\nIt is the first conventional subway, running in a deep-bored tunnel below Yuzhong and Shapingba Districts.\nLine 1 has transfer interchange stations with [Line 6](https://bliptext.com/articles/line-6-chongqing-rail-transit) at [Xiaoshizi](https://bliptext.com/articles/xiaoshizi-station) and [Line 2](https://bliptext.com/articles/line-2-chongqing-rail-transit) at [Jiaochangkou](https://bliptext.com/articles/jiaochangkou-station) in Jiefangbei CBD and at [Daping](https://bliptext.com/articles/daping-station) and [Line 3](https://bliptext.com/articles/line-3-chongqing-rail-transit) at [Lianglukou](https://bliptext.com/articles/lianglukou-station), which is near [Chongqing railway station](https://bliptext.com/articles/chongqing-railway-station) in central Yuzhong.\nLine 1 is also transferable with the [Loop Line](https://bliptext.com/articles/loop-line-chongqing-rail-transit) at [Shapingba](https://bliptext.com/articles/shapingba-station), although out-of-station transfer is currently needed due to construction setbacks on the interchange channel and concourse connecting the two subway lines.\nIn 1992, the Chongqing government signed a [Build-Operate-Transfer](https://bliptext.com/articles/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.\nWork resumed from Chaotianmen to Shapingba on 9 June 2009, and a limited opening occurred on 28 July 2011.\n[Thales](https://bliptext.com/articles/thales-group) provided an [operations control centre](https://bliptext.com/articles/control-room) for the line.\nLine 1's color is **red**.\n\n## Line 2\nLine 2, a [monorail](https://bliptext.com/articles/monorail) line, runs 31.4 km and has 25 stations.\nIt begins as a subway under downtown Jiefangbei, then runs west along the southern bank of [Jialing River](https://bliptext.com/articles/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](https://bliptext.com/articles/ba-nan-district-chongqing).\nIt runs mostly elevated, but a 2.2 km section is underground, including three of its 18 stations in the [Jiefangbei CBD](https://bliptext.com/articles/jiefangbei-cbd) and central Daping areas in the extremely-dense area of Yuzhong District.\n[Line 2](https://bliptext.com/articles/line-2-chongqing-rail-transit) runs through four administrative districts in the central city ([Yuzhong](https://bliptext.com/articles/yuzhong-district), [Jiulongpo](https://bliptext.com/articles/jiulongpo-district), [Dadukou](https://bliptext.com/articles/dadukou-district), and [Ba'nan](https://bliptext.com/articles/banan-district-chongqing)).\nIn 2010, Line 2 served 45 million passengers.\nIt also runs through Daping CBD, Yangjiaping CBD in Jiulongpo District, and Chongqing Zoo at.\nMost trains have four cars, and six-car trains began to operate in September 2012.\nLine 2 is the first rapid transit line to open in the Interior West of China, in 2005.\nIn 2013, six-car trains are being implemented because of overcrowding and increasing demand.\nLine 2's color is **green**.\n\n## Line 3\nLine 3 is the longest and busiest monorail in the world.\nIt runs from north to south and links the districts separated by the [Yangtze](https://bliptext.com/articles/yangtze) (Chang Jiang) and the [Jialing](https://bliptext.com/articles/jialing-river) Rivers.\nThe initial segment, from Lianglukou to Yuanyang (18 stations, 17.5 km), opened on 29 September 2011, with a northern extension, from Yuanyang to [Jiangbei Airport](https://bliptext.com/articles/jiangbei-airport), opening on 30 December 2011.\nA southern extension, from Ertang to Yudong, opened on 28 December 2012.\nMost trains have six cars, more than on the older Line 2.\nThe line started to equip eight-car trains in 2014, which are now in operation.\nThere are interchange stations in the Yuzhong district with Line 1, at Lianglukou (Caiyuanba Intercity Railway/Coach Station), and with Line 2, at.\nLine 3's color is **indigo**.\n\n## Line 4\nLine 4 is a rapid transit line.\nIn June 2018, debugging of the first segment of Phase I commenced.\nThe line began operating on 28 December that year.\nLine 4's color is **orange**.\n\n## Line 5\nLine 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.\nIt will connect Yubei, Jiangbei, Yuzhong, Jiulongpo, Shapingba and Dadukou districts.\nNew six-car trains were introduced on the line.\nLine 5's color is **light blue**.\n\n## Line 6\nLine 6 is the second heavy-rail subway line of Chongqing.\nOpened on 28 September 2012, it connects Nan'an, Yuzhong, Jiangbei and Yubei districts in central Chongqing.\nA northern branch, from Lijia to Wulukou, Beibei District, was opened on 31 December 2013, 26.2 km long with five stations.\nPhase 1 of the Chayuan extension was opened in 2014.\n[Thales](https://bliptext.com/articles/thales-group) provided an [operations control centre](https://bliptext.com/articles/control-room) for the line.\nLine 6's color is **pink**.\n\n## Line 9\nThe first phase of Line 9 opened on 25 January 2022.\nLine 9's colour is **crimson**.\n\n## Line 10\nThe line serves [the North Railway station](https://bliptext.com/articles/chongqing-north-railway-station) and the airport terminals.\nThe 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.\nTwo new bridges, Zengjiayan Jialing River Bridge and Nanjimen Rail Transit Bridge, are under construction for train services to the south.\nLine 10's color is **purple**.\n\n## Jiangtiao line\nJiangtiao line is a suburban [rapid transit](https://bliptext.com/articles/rapid-transit) line connecting [Jiangjin District](https://bliptext.com/articles/jiangjin-district) with the metropolitan area.\nThere will be [through service](https://bliptext.com/articles/through-service) between Line 5 and Jiangtiao line in the future.\nJiangtiao line's color is **blue**.\n\n# Ticketing\n\n## Transport cards\nCRT accepts [Life & Transport Card](https://bliptext.com/articles/life-transport-card) (Chongqing Universal Card, released by [Chongqing City Card Payment Co., Ltd.](https://bliptext.com/articles/chongqing-city-card-payment-co-ltd)) and its compatible cards, released by partner companies in other cities of China.\nThere is a 10% discount applied to the Regular Card if it is used on public transit in the city.\nThe 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).\nThe Regular Card can be purchased at any CRT station, and a deposit can be recovered when the card is returned with its receipt.\nIn addition the card can be used in many shops, cinemas, restaurants, etc. in Chongqing.\nThe 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.\n\n## Time limit\nAll 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.\n\n# Operation\nDuring times of heavy use like for major events, CRT may close some stations to avoid overcrowding.\nIn 2018, CRT closed Xiaoshizi, Jiaochangkou, Qixinggang, Lianglukou, Xiaolongkan, and Shapingba stations of Line 1; Jiaochangkou and Linjiangmen stations of Line 2; Lianglukou, Huaxinjie, Guanyinqiao, and Hongqihegou stations of Line 3; Shangxinjie, Xiaoshizi, Grand Theater, Jiangbeicheng, and Hongqihegou stations of Line 6 after 20:00 on Christmas Eve, Christmas Day, after 19:00 on New Year's

Accessibility\nAlmost every station has accessible elevators and toilets, and almost every train has wheelchair locks.\nOnly the oldest rolling stock and toilets of Line 2 are not fully accessible.\nIn 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.\n\n## Luggage rack\nThe trains on Line 10, which links [Jiangbei Airport](https://bliptext.com/articles/jiangbei-airport) and [Chongqing North railway station](https://bliptext.com/articles/chongqing-north-railway-station), are equipped with a luggage rack on each car.\n\n# History\nThe CRT is part of the central government's project to [develop the
