Today I will make a round trip with Trieste as departure and arrival station. I will go through 3 different countries: Italy, Austria and Slovenia.
The station replaced the former Tarvisio Centrale and Tarvisio Città railway stations, opened in 1879. Tarvisio Centrale is still used as a terminus for bus services from Udine. The former Tarvisio–Ljubljana Railway to Jesenice railway station in Slovenia has been closed to traffic since 1967."
The tunnel is still of importance to international train traffic. It is traversed by more than 80 trains a day."
During the First World War, it carried the majority of Austrian military supplies to the Isonzo Front. Due to new political divisions in Europe, with the dissolution of Austria-Hungary into separate states in 1918 and the isolation of communist Yugoslavia after 1945, the railway decreased in importance during the twentieth century. However, Slovenia's accession to the European Union has created new prospects for the railway as a convenient passenger and freight route from Central and Eastern Europe to the port of Trieste."
