The first plans for a mainline railway (Fernbahn) from Kempten over the Fern Pass to Innsbruck surfaced in the second half of the 19th century. On 1 December 1895 the first section from Kempten to Pfronten-Ried was opened, followed in 1905 by its extension to Schönbichl. From Schönbichl there was a Lokalbahn branch line to Reutte.
