Hongyancun station (Chinese: 红岩村站; pinyin: Hóngyáncūn zhàn) is a station on Line 9 of Chongqing Rail Transit in Chongqing Municipality, China, that opened in 2022. It is located in Yuzhong District. Line 5 also reaches the station since November 2023.
The station is the deepest metro station in the world. The deepest point of the station is 116 meters (381 ft) below the ground and the top of rail is 106 meters (348 ft) below the surface. Regardless, the depth breaks China's previous record depth of Line 10's Hongtudi station and surpasses the depth of the Kyiv Metro's Arsenalna station, the previous record for deepest metro station.
The vertical height difference between Entrance 2 and Entrance 4 of the station is over 141 meters (463 ft). From Entrance 2, passengers will need to take a three-segment ascending moving walkway that is approximately 105 meters long, and it takes about 6 minutes to access the Line 9 platform; while from Entrance 4, its a seven-segment descending escalator ride that takes about 8 minutes (if not by lift).
