What is the longest railway line in the world, running from Moscow to Vladivostok?

The Trans-Siberian Railway is the world’s longest railway line, connecting Moscow with Vladivostok across Russia.

The classic Moscow–Vladivostok route covers about 9,289 kilometres and crosses eight time zones. Construction began during the Russian Empire in 1891 and the main route was completed in the early twentieth century. It links European Russia with Siberia and the Russian Far East.

The railway is a network rather than one single track in every modern usage. Branches connect with Mongolia, China, and North Korea, including routes associated with the Trans-Mongolian and Trans-Manchurian railways. These services are related but are not identical to the core Trans-Siberian route.

A full journey on the principal line takes about a week without a long stopover. The railway remains important for passengers, regional travel, and freight, especially across Russia’s enormous interior.
