Deepest subway station in works

Chongqing is about to break its own record for the deepest subway station in China.

The southwestern city, located in an area crisscrossed by rivers and mountains, is building train platforms 94.46 meters underground as part of the ongoing extension of the Chongqing Metro network.

Hongtudi station, which opened on Line 6 in December 2014, was already the country's deepest station at 60 meters below ground. Now, it is being pushed even deeper to connect with Line 10, which is under construction.
