Hintertux is the only ski region worldwide with a three-section Funitel system. The latest Funitel, Gletscherbus 1, went into service in November 2008. The three sections now lead from the base station in Hintertux (1,500 m) to Sommerbergalm (2,100 m), Fernerhaus (2,660 m) and Gefrorene Wand at an altitude of 3,250 m, covering a total length of 5,538 m. The desire for comfort, operational reliability and the best in ropeway engineering is the key factor which inspired the construction of the first two sections (Gletscherbus 2 and Gletscherbus 3) in 1996 and 1999 respectively.

The crucial argument in favor of using the Funitel technology is always the system‘s wind stability. Hintertux lies right in the path of the “föhn“ wind and is consequently exposed to high wind speeds. It is therefore essential to ensure that passengers can be brought back safely from the glacier even under adverse weather conditions. Gletscherbus 1 is equipped with 24 CWA cabins and achieves a transport capacity of 3,200 passengers an hour each way at its maximum speed of 6 m/s.
