On the Dave & Ryan show they said they will have a final answer on the Bell before the preorder period ends. Its not guaranteed. I would love to have a 3rd engine (have a Vision Line Hudson and Vision Line CC2) with the swinging bell. Everyone loves it when they see it.
I think they pulled it from the online catalog until they have a final answer, I don't see it anymore.
I think it should be a standard feature like whistle steam!
