The Moscow to Vladivostok railroad may be the longest single rail system in the world - but that doesn't mean it's the longest train journey (without changing).
"The route extends through Irkutsk and Ulan-Ude, following the southern shore of Lake Baikal between those cities, and then moves roughly in parallel to Russia's border with Mongolia and then China before arriving at Khabarovsk on the Amur River and, finally, at Vladivostok on the Sea of Japan.".
Starting in the country's capital of Moscow and ending up Vladivostok - a major Pacific port city near the border with China and North Korea - this journey spans a staggering 5,771 miles (9,288 km).
The Trans-Siberian Railroad is no mean feat: transporting passengers almost across the entirety of Russia, the world's largest country by land area.
"The railroad's main route passes through Yekaterinburg and crosses the Ural Mountains before reaching Novosibirsk on the Ob River and then Krasnoyarsk on the Yenisey River," Britannica explains.
