Line 1 runs {{convert|16.4|km|mi|abbr=on}} from Chaotianmen, in the central west, to Shapingba and then to Bishan with a total length of {{convert|44.5|km|mi|abbr=on}}. 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. Work resumed from Chaotianmen to Shapingba on 9 June 2009, and a limited opening occurred on 28 July 2011.{{cite news|url=https://www.echinacities.com/news/Chongqings-Metro-Line-1-Now-Open |access-date=31 May 2021 |title=Chongqing's metro Line 1 now open |publisher=China Cities |url-status=live |archive-url=https://web.archive.org/web/20110827204844/http://www.echinacities.com/chongqing/city-in-pulse/chongqing-s-metro-line-1-now-open.html |archive-date=27 August 2011 |df=dmy }} Thales provided an operations control centre for the line.

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.{{cite web|url=http://www.cqmetro.cn/wwwroot_release/crtweb/yyfw/pwzc/319239.shtml |script-title=zh:重庆市轨道交通票务规则|website=Chongqing Rail Transit|language=zh-cn|access-date=9 August 2016}}

Unlike most metro systems of other cities in China, CRT did not follow the design style of MTR Corporation in Hong Kong. The signage system was designed by GK Design Group in Japan, and the monorail lines are based on Hitachi Monorail technology. That gives the Chongqing Rail Transit a distinctive Japanese aesthetic, in contrast to other metro systems in China.{{Cite journal|year=2012|title=Chongqing City Subway Total Signage System, Lines No.1 and No.3 Signage Design Plan / Chongqing Metro|url=http://www.gk-design.co.jp/GK_Report/GKReport_23.pdf|journal=GK Report|publisher=GK Design Group|issue=23|pages=24|access-date=7 April 2017}}
