Trains Between China and Mongolia

Written by ivana Updated Jan. 10, 2025

The famous Trans-Mongolian Railway, one of the branches of the Trans-Siberian Railway, is the most important railway connecting Russia, Mongolia and China. The line links with the Trans-Siberian at Ulan-Ude. Two pairs of trains run on the Trans-Mongolian Railway weekly – train 3/4 (called K3/K4 in China) and train K23/K24 – taking 30 hours to cover 2,215 kilometers (1,376 miles).

History of the Trans-Mongolian Railway

The Trans-Mongolian Railway was built in the middle of the 20th century, from Ulan-Ude, Russia, to Beijing, the capital of China, crossing the Gobi desert and passing through Mongolia’s capital, Ulaanbaatar.

The Chinese track gauge is 1,435 mm. Track gauge in Mongolia and Russia is 1,520 mm. So the train needs to have its bogies changed at Erlian, the border city between China and Mongolia.
