I am looking to buy a used steamer. Nothing expensive but running good. I would like smoke from the locomotive stack and the choo choo sound. I like the looks of the ones with three big wheels, but they seem to all be smoke in tender. Does that mean the smoke actually comes out of the tender and not the locomotive? Like I said, and a old newbie. Looked at 312 310 etc. Perhaps someone has something I might be interested in here.
