Bohinj Railway, Railway line in Slovenia and Italy

The Bohinj Railway, also known as the Wocheiner Bahn or Transalpina, is a single-track railway line that runs from Jesenice in Slovenia to Trieste in Italy. It passes through the Julian Alps, crosses the border at Nova Gorica and Gorizia, and ends at Trieste Campo Marzio station.

The railway was built as part of the New Alpine Railways project and opened in 1906. It was later divided between Italy and Yugoslavia after the world wars, and the Italian section was reopened in 2020 after repairs.

The railway is known by different names in each country: Wocheiner Bahn in German, Bohinjska proga in Slovene, and Ferrovia Transalpina in Italian. In Gorizia, the square outside the station is called Piazza Transalpina, a reminder of the line's past.

The line is long and crosses international borders, so carry your passport or ID. Check local schedules in advance, as services may be infrequent and some sections have limited runs.

The Bohinj Tunnel is the longest tunnel on the line and was originally built with two tracks, though only one is now in use. The second track space serves as a drainage channel that can fill with water during heavy rain or snowmelt.
