The Trans-Siberian Railway is the most famous railway in Russia. The longest railway in the world was built within only 14 years – an unprecedentedly short time – 9515 kilometers of track. Hundreds of bridges were built along the way, and 7 kilometers of tunnels were laid through mountains. An unbroken rail track linked Vladivostok with Moscow and St. Petersburg, linking two oceanic coasts. The line not only gave a powerful impetus to the industrial development of the internal regions of Russia, but also solved many military and political problems.
