This underground train repair facility in China was completed in 1972, and it abruptly ceased operations in 2008 due the restriction of locomotives on certain tracks. 

Since then, this underground workshop has been frozen in time.

Over the course of 35 years, it repaired over 1500 locomotives

In the late 1960s, a nationwide war preparation effort against the Soviet Union was launched. A proposal was made to construct a combat ready locomotive repair factory to safeguard against enemy bombings and ensure maximum safety. 

Construction was completed in 1972, and officially opened a year later with the annual overhaul capacity of 50 locomotives 

Initially the factory opened under semi-military management. There was a dedicated military unit within the factory responsible for patrolling and protecting the facility. 

In the 1980s the factory was declassified and began providing maintenance services for train locomotives.
