The Trans-Siberian Railway remains the longest regular, continuous train journey in the world in 2026. The classic route runs from Moscow to Vladivostok, covering a staggering 9,289 kilometers (5,772 miles). This epic journey crosses eight different time zones and takes approximately six to seven days (164+ hours) to complete if done in a single non-stop leg. Passengers travel across two continents (Europe and Asia), passing through the Ural Mountains and alongside the shores of Lake Baikal. While there are "luxury" versions of this trip, the regular "Rossiya" train (Train No. 001/002) is a standard passenger service used by locals and intrepid travelers alike. In 2026, despite regional geopolitical shifts, the railway remains a critical artery for Russian domestic travel. For those seeking international variety, the "longest" journey by a single ticket (but involving multiple trains) now often includes the route from Portugal to Vietnam, spanning over 17,000 km.
