Polish State Railways in summer 1939
In the summer of 1939, weeks ahead of the Nazi German and Soviet invasion of Poland the map of both Europe and Poland looked very different from today. The railway network of interwar Poland had little in common with the postwar reality of dramatically changing borders and political domination of the Soviet-style communism, as well as the pre-independence German, Austrian and Russian networks which the Second Polish Republic had partially inherited in 1918 after the end of World War I. The most important junctions in the Polish territory in summer of 1939 were: Lwów (Lviv), Tarnopol (Ternopil), Stanisławów (Ivano-Frankivsk), Stryj (Stryi), Kowel (Kovel), Chodorów (Khodoriv), Kołomyja (Kolomyia) and Sarny – all now in Ukraine, Łuniniec (Luninyets), Baranowicze (Baranavichy), Brześć nad Bugiem (Brest), Lida, Wołkowysk (Vawkavysk) and Mołodeczno (Maladzyechna) – all now in Belarus, Wilno (Vilnius), Landwarów (Lentvaris) – now in Lithuania, Cieszyn Zachodni (Český Těšín), Bogumin (Bohumín) – now in the Czech Republic.
