at the end of the Ostbahn - Eydtkuhnen

Until 1945 a town in East Prussia, Germany, Eydtkuhnen was the eastern-most terminus of the Prussian Eastern Railway that was finished in 1860 and connected Berlin with the Saint Petersburg – Warsaw Railway in the then Russian Empire. Passengers going further, such as on the Nord Express had to change to a Russian gauge train (see earlier post on the Ostbahn).

After 1945 with Stalin's border changes, it found itself in the Russian enclave, renamed Chernyshevskoye.
