In the 19th century the Ritten plateau was a popular place for the people of Bolzano, who liked to pass their weekends there. To connect the two places, it was decided to build a rack railway, and in 1906 the railway engineer Josef Riehl commenced the planning of the line. In April 1907 construction was finished, and the railway was officially inaugurated on 13 August 1907. The full length of the line, from Walterplatz in Bolzano to Klobenstein, was 11.75 km.
