As early as 1891, there were plans to construct a railway between Ora and the Val di Fiemme Valley in order to improve accessibility and stimulate the economy. The Val di Fiemme railway line was built during World War I. Between 1918 and 1936, it was used mainly for transporting goods. It connected Auer/Ora with Predazzo. The segment between Auer and San Lugano is still in good condition. Nowadays, it is a very nice hike and cycle path which leads through the beautiful mountain landscape of the Trudner Horn Nature Park and is especially worthwhile due to the views of the South Tyrolean Unterland region.
