It doesn't do "choo-choo" but it's a train

Overheard in the train tonight:"This, is a train, it doesn't do "choo-choo" but it's a train" says a mother to her kid point at the nice IC2000 CFF Double-decker train.

Why do I blog this? It's curious how onomatopoeia, which start becoming names for things can survive after the artifact's behavior becomes utterly different. It's always intriguing when the naming of things goes berserk. The noise, (i.e. one of the physical manifestation) is more important than the appearance and the behavior.

Choo-Choo, now it's a wrong onomatopoeia. Other examples?
