Some time ago I noticed the 0-6-0 steam switchers that Atlas put out back around 2006 to 2010... I did some searching for videos of these engines being operated, and for overall impressions but haven't found a lot said about them.
So - for any of you that happen to have one of these, how would you "review" these engines? They certainly seem to look like really nice models from the little I have seen of them. One thing I wondered about though was one video I did find the engine seemed to have only one "chuff" per wheel revolution rather than the prototypical four... Is this something they all have in common or did this differ depending on which production batch they came from? Any other overall impressions of the engines?
For reference I'd be most interested in the 3 rail versions since that's what I operate and would want if I happened to stumble on to one someday.
Thanks!
