context_page_description: The Chongqing Rail Transit is the rapid transit system in the city of Chongqing, China. In operation since 2005, it serves the transportation needs of the city's main business and entertainment downtown areas and inner suburbs. As of December 2019, CRT consisted of eight lines, with a total track length of 326.9 km. Lines 1, 4, 5, 6, 10 and the Loop line are conventional heavy-rail subways, while Lines 2 and 3 are high-capacity monorails. To keep up with urban growth, construction is under way on Lines 9, 18 and S5, in addition to extensions to Lines 1, 4, 5, 6, 10 and the Loop line. A network of 18 lines is planned.
  The Chongqing Rail Transit is a unique transit system in China because of the geography of Chongqing being a densely-populated but mountainous city, with multiple river valleys. Two lines use heavy-monorail technology, leveraging the ability to negotiate steep grades and tight curves and rapid transit capacity. They are capable of transporting 32,000 passengers per hour per direction.
context_section_description: The Loop line (also known as "Line 0"; Chinese: 零号线) is a rapid transit loop line.  The northeastern section was opened on 28 December 2018. When the line is fully completed, it will run through two important railway stations: Chongqing North Railway Station, and Chongqing West Railway Station.
