Túnel El Árbol, Historical railway tunnel in Pichilemu, Chile.
The tunnel extends for 1,960 meters through the mountain, featuring a height of 6 meters and a width of 4.5 meters throughout its length.
Construction of the tunnel began in December 1900 and finished in May 1904, marking a period of substantial railway development in the San Fernando-Pichilemu region.
The tunnel received designation as a Historical Monument of Chile in 1993 through Decree 192, recognizing its contribution to national railway heritage.
Visitors can access the tunnel site by following the former San Fernando-Pichilemu railway line between Cardonal station and the former El Lingue station.
The construction teams achieved remarkable precision, with only eight centimeters horizontal and twelve centimeters vertical deviation when connecting both tunnel sections.
