Przeworska Kolej Wąskotorowa, Przeworsk Wąski
The Pogórzanin route is considered to be the most picturesque among Polish narrow gauge railways, mainly due to the diversity of landscapes. It runs through the valleys of two rivers – the Wisłok and the San, fields, meadows, marshes and forests of the Dynowskie Foothills and abounds in numerous curves and climbs. It is famous for containing the only narrow-gauge railway tunnel in Poland, located in Szklary and 602 metres long.
