Fleimstalbahn Tunnel

Atmospheric former railway tunnels with automatic lighting. Very smooth and fast gravel / dirt road - great for gravel

When I was there, the tunnel was still being renovated.

The Fiemme Valley Railway was a narrow-gauge railway line between Auer in the Unterland (South Tyrol) and Predazzo in the Fiemme Valley (Italian: Val di Fiemme, Trentino), which was in operation from 1917 to 1963. As early as 1910, the project planning application of the greater municipality of Fiemme Valley (Magnifica Comunità Val di Fiemme) was submitted to the k.k. Ministry of Railways was approved and the work was assigned to an Italian-speaking engineer. With the outbreak of the First World War these plans were initially frozen.
However, with Italy's entry into the war in 1915 and the start of the Dolomites War, the supply route via the existing roads proved to be inadequate and the plans for the Fiemme Valley Railway were revived. Several variants, such as a cog railway Auer–Pausa, cable cars and funiculars, had previously been investigated.
