The Trans-Siberian is one of the world’s most famous train rides: from Moscow to Vladivostok, and with connecting branch lines into Mongolia, China, and North Korea, it’s also the longest railway in the world (5,772 miles). Many travelers decide to take this train journey across Russia to discover the country beyond Moscow or St. Petersburg and find out what it means to spend two weeks on a train.

This video, shot by J.J. Guillermo during a two-week journey this summer, takes us from Moscow to cities like Ekaterinburg, Irkutsk, Baikal Lake, and Ulan-Ude, where he took the Trans-Mongolian route to Ulaanbaatar and the “spectacular Mongolian countryside.” A 3,900-mile journey recorded on video to make anyone who’s watching wonder why they still haven’t seen Asia through a train window.
