Well if a dog can do it - she thought, and stepped into the car which rocked violently, feeling quite brave. This feeling disappeared immediately as the car dropped rapidly down the cliff face into space. She looked down once and was so appalled at the distance they were from the ground that she closed her eyes quickly as a shudder of absolute terror went through her.

From SUSAN INTERFERES, Chapter 5, Looking for Fräulein Amacher. The cable car rides up to Wissifluh and back and the terror that Susan feels in the little red conveyance are described in detail in this chapter and provide the best moments of humour in the book. The cable car is described as a "small red tin box" and a "tin can". Only Bill enjoys the ride, while the girls are terrified.
