Stretching 2,215 kilometers (1,376 miles) from Mongolia’s northern border with Russia to China’s Inner Mongolia Autonomous Region in the south, the Trans-Mongolian Railway was completed in 1956 after nearly two decades of construction across some of the planet’s most scenic but arduous landscapes.
The train rumbles through stands of taiga (boreal forest), across the fabled steppes of central Mongolia and then the seemingly endless Gobi Desert. Remote towns and settlements flank the tracks, but signs of civilization are few and far between, especially during winter when much of Mongolia is draped in snow.
