The Trans-Siberian Railway also played a very direct role during parts of Russia's history, with the Czechoslovak Legion using heavily armed and armoured trains to control large amounts of the railway (and of Russia itself) during the Russian Civil War at the end of World War I. As one of the few organised fighting forces left in the aftermath of the imperial collapse, and before the Red Army took control, the Czechs and Slovaks were able to use their organisation and the resources of the railway to establish a temporary zone of control before eventually continuing onwards towards Vladivostok, from where they emigrated back to Czechoslovakia.
