Did you know that Russia has the world's longest railway? The Trans-Siberian Railway runs 5,772 kilometres from Moscow to Vladivostock. The Trans-Siberian Railway makes it simple to travel throughout Russia by rail at your own pace. Depending on your budget and desired experience, you can ride in a first-class cabin or third-class seats. If you want to travel China or Mongolia, the Trans-Siberian Railway links to those nations as well.
