Latający Wilnianin (English: Flying Vilnian) was the popular name of a passenger train which in the interbellum period linked Warsaw with Wilno (now Vilnius, Lithuania).
Another name for that train was Gwiazda Północy (The Star of the North).
[1] 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 the summer of 1939, the fast train left Warsaw daily at 9:05 to arrive at Wilno at 14:50.
[2] A second daily train between the two cities left Warsaw West at 16:41 and arrived at Wilno at 22:31.
