Garaventa & Sons of Goldau, and the large cabins were supplied by the Carrosseriewerke Company of Aarburg.On the 25th anniversary of the opening of the cable car (in 1993), the original two red passenger cabins were replaced by modern panorama cabins.In 1992 the two railway companies merged to become the Rigi Railways Company and in the same year took over the Rigi Ski Lift Company.
