Trans-Siberian Railway Section Opens

The opening of the Irkutsk to Lake Baikal segment on May 21, 1900, represented a major engineering triumph for the Trans-Siberian Railway under Tsar Nicholas II. Workers battled permafrost and mountainous terrain using steam shovels and thousands of laborers. This 70-kilometer stretch included the first major tunnels and bridges over the Angara River. It enabled faster transport of goods and troops, connecting European Russia to the Far East. The event boosted Russia's industrial growth and played a strategic role in the Russo-Japanese War, leaving a lasting legacy as one of the world's longest rail arteries still in operation today.
