Trans-Siberian Railway completed

July 7, 1904, marked the ceremonial completion of the Trans-Siberian Railway when the last rail was laid near the Amur River. Spanning over 9,000 kilometers, this monumental project under Tsar Nicholas II employed tens of thousands of workers and featured innovative engineering solutions such as the massive bridges over the Ob and Yenisei rivers. It dramatically shortened travel time from Moscow to the Pacific from months by sea to just days by rail, boosting colonization of Siberia and military logistics during the Russo-Japanese War. The railway used powerful 2-8-0 locomotives and included the famous Circum-Baikal section carved into cliffs. Its lasting impact includes shaping Russia's geopolitical reach and inspiring countless model railroad recreations of its vast scale.
