Latający Wilnianin (English: Flying Wilnianin ) was the popular name of a passenger train which in the interbellum period linked Warsaw with Wilno (now Vilnius in Lithuania). Another name for that train was Gwiazda Północy (The Star of the North).
In 1919, it took around 20 hours for a train to cross the distance of 423 kilometers between Warszawa Zachodnia (Warsaw West) and the station in Wilno. In 1939, this distance was crossed in 5 hours and 45 minutes. In the summer of 1939, the fast train left Warsaw daily at 9:05 to arrive at Wilno at 14:50. A second daily train between the two cities left Warsaw West at 16:41 and arrived at Wilno at 22:31.
