Crews have begun tunneling Line 10 in southwest China's Chongqing Municipality.

Line 10, to run below the existing Line 6, will require passengers going almost 95 meters underground.

Currently, the Hongtudi Station on Line 6 in Chongqing takes 3 minutes on an escalator to reach the platform, which is 60 meters below ground.

Line 10's stop will take people down an extra 30 meters. The yet-to-be-named stop, being built below Hongtudi Station, is being dug at approximately 94.5 meters below the surface. This is the equivalent of 31 stories underground.

Once complete, Chongqing's Line 10 will have 19 different stops, running 34 kilometers. It's due to be completed sometime in 2017.

The existing Line 6 and the new Line 10 will share 3 exits. A total of 91 elevators will also be available for passengers.

Chongqing is renowned for its steep terrain, as the city was originally built among the local mountains.
