Selecting the route

In Austro-Hungarian economic circles, the first initiatives for the second Vienna–Trieste line appeared relatively soon after the construction of the Southern Railway. However, the final decision on construction was not reached until 6 June 1901 because various plans were under consideration from the start.

In addition to the Bohinj plan (the last to be proposed, in 1844), the Predel and Å kofja Loka plans were also considered.

In the end, the Bohinj route was chosen, despite being the most demanding in terms of construction and geological features, and thus the least appropriate. The military cast the decisive vote, because it needed a safe railway connection for its own use sufficiently far away from the border.
