Sibirjak is the German spelling of the Russian name (Сибиряк) of a passenger train which currently links Berlin to some of main routes and cities of Russia. Its name means Siberian. (A conventional English form of the name would be Sibiryak or Siberiac.) The train passes through Germany, Poland, Belarus, Russia and Kazakhstan, partly traveling on the Trans-Siberian Railway. With 5,130 km from Berlin to Novosibirsk it is the longest route of any that depart from a station within the European Union.
