An extension of the route to the south to Biasca in the canton of Ticino, connecting to the Gotthard Railway towards Chiasso was considered around 1900. In 1963, the Schweizerische Aktionskomitee pro Tödi-Greina-Bahn (Swiss Action Committee for the Tödi-Greina Railway), which had representatives from several cantonal governments, commissioned a study to examine the feasibility of a Tödi-Greina railway. These plans were not pursued.
