Hello, I was surprised to open a new purchase..."Lionel 6-18922 New Haven "A" Alcoa Diesel Dummy" and it had not only lights, but drive motor, traction bands on the drive wheels, USED and at a used dummy price.
So the obvious answer, even to a n00b like me is that it was changed, but sold by the "item number"? No horn (sadly)
Guess I answered my own question. and with as smooth as this runs through my 022 switches, my beloved, smoking, easy-to-derail- steam engines will stay on the siding or run around the circle...
I heard my Mentor say, "stick with the diesels for daily running, they stay on the tracks...." (wink)
