The Trans-Siberian Railway spans almost all the way across the county, making it the single longest railway in the world. The 9200 kilometer (or 5700 mile) railway departs in moscow (located in European Russia) and crosses into Asia. It then makes its way to the Pacific Ocean port of Vladivostok where it reaches the end of its incredible journey. The entire journey non-stop will take you 152 hours and 27 minutes to complete.
