# Hongtudi station

Hongtudi is an interchange station on Line 6 and Line 10 of Chongqing Rail Transit in Chongqing Municipality, China. It is located in the Jiangbei District. The lowest level being 94 meters below ground makes it one of the world's deepest subway stations.

## History

In 2012, the opening of the Line 6 platforms made the station the deepest subway station in China, at over 60 meters below the surface. In 2017, the station became even deeper with the opening of Line 10 platforms, reaching over 94 meters below the ground. The new Line 10 platforms became one of the deepest subway stations in the world after Arsenalna Station in the Kyiv Metro. (Currently the record has been broken by Hongyancun station of Line 9, reaching 116 meters below the ground) The journey from the surface to Line 10 platforms takes over 5 minutes. The station's extreme depth, large transfer demand between the two lines and numerous entrances on the surface necessitates the need for over 91 escalators to be installed throughout the entire station.
