The Ulaanbaatar Metro project was approved in 2012,[1] and construction was originally planned to be completed by 2020, however, as of 2023[update] it is still not open.

[1] On December 23, 2023, the Minister of Mongolia B. Delgersaikhan, Chair of the National Committee on the Reduction of Traffic Congestion in Ulaanbaatar, and Kh.

Nyambaatar, the Governor of the Capital City, and the Mayor of Ulaanbaatar City were granted the right to organize the work to announce an international bidding for contractors and management consulting services for the construction of the metro in Ulaanbaatar in 2024-2028, ensuring compliance with all relevant laws and regulations.

[8] The meeting resulted in revising the mass transit studies done by the Japanese firms in 2012 as Ulaanbaatar has grown widely since then.

The route runs from east to west and lacks any sharp turns and bends, allowing the metro to reach its top speed of 100 km/h (65 mph).
