The Trans-Siberian Railway is the world’s longest single continuous rail line, spanning about 9,289 kilometers from Moscow to Vladivostok across eight time zones, vast taiga forests, steppe, mountains, and 16 major rivers.
Construction began in 1891 under Tsar Alexander III, with Tsarevich Nicholas II laying the first stone in Vladivostok. The project aimed to unite the Russian Empire, boost trade with Asia, and develop Siberia’s resources.
Built in sections from both ends amid harsh terrain and permafrost, the full Russian route (avoiding earlier Manchurian shortcuts) was completed in 1916. It later supported Soviet industrialization, World War II logistics, and remains a key passenger and freight corridor operated by Russian Railways.
The premier service is the Rossiya train number 001/002, a comfortable firmeny train with renovated carriages featuring air conditioning, power outlets, USB ports, and showers in some cars. It offers first-class (two-berth), second-class kupe (four-berth), and...
