Bolzano, the capital of the province of South Tyrol, has a population of 100,000. Until 1966 an interurban tram line linked Bolzano with the villlages on the Ritten plateau. A four kilometre long section was so steep (up to 25%), that the trams were pushed by a cogwheel locomotive. The section within the city of Bolzano and the cogwheel section were abandoned in 1966, the part on the Ritten plateau between Himmelfahrt and Klobenstein is still in operation. From Bolzano, a cableway or a bus must first be used to get to the line.
