The Białą Górą Tunnel (Tunel pod Białą Górą), also known as the Kozłowski Tunnel, is a railway tunnel complex in the Lesser Poland Voivodeship of southern Poland. It carries the Warszawa Zachodnia–Kraków Główny railway beneath Biała Góra near the village of Tunel, between Miechów and Kozłów.[1]

The complex consists of two parallel single-track bores, each 764 m (2,507 ft) long.[1][2] It is one of the longest historic railway tunnels in Poland and the longest on line no. 8.[2]

Description

The tunnel lies at km 266.617–267.381 of railway line no. 8, the main railway route linking Warsaw and Kraków.[1] Atlas Kolejowy describes the structure as two electrified single-track bores in regular use.[1]

The tunnel passes beneath Biała Góra, a chalk hill rising to about 415–416 m above sea level in the northern part of Lesser Poland.[3][4] The locality of Tunel takes its name from the railway tunnel.[3]

Atlas Kolejowy notes, “for the record”, that the two bores are named August for track no. 1 and Włodzimierz for track no. 2.[1]

History

The first tunnel bore was built as part of the Ivangorod–Dąbrowa Railway, the strategic railway linking the Russian partition with the Dąbrowa Basin and the Austrian frontier.[1][4] Atlas Kolejowy gives the opening date of the original bore as 25 January 1885.[1]

A local historical brochure issued for the “W lasach tunelskich” trail states that a second, parallel bore was constructed in 1910–1912 as traffic increased on the line.[5]

The same brochure notes that the tunnels were built for strategic reasons, since disabling them would interrupt rail communication toward Upper Silesia.[5] During the First World War and again in 1945, the tunnel complex suffered wartime damage, after which it was rebuilt and returned to use.[5][4]

In recent decades the tunnel has remained an important element of the heavily used north–south railway corridor on line no. 8.[1] In planning documents and regional policy debates, proposals have periodically appeared for a new alignment between Miechów, Charsznica and Kozłów that would bypass the tunnel in order to increase line capacity.[6][7]

Significance

The Białą Górą Tunnel is one of the most recognizable railway structures in the Miechów area.[3] A 2024 geological review of Polish transport tunnels lists it among the notable railway tunnels of the country and gives its length as 764 m (2,507 ft).[2]
