Personally, I do not like when the importers choose this approach of announcing/producing individual passenger cars over a period of years. I've tolerated it with Lionel's Polar Express (scale cars), but that's been my sole exception. I much prefer when an entire "set" is offered... at least a 4- or 5-pack WITH observation so a short train can be run. The overseas manufacturing relationships are too precarious right now to risk purchasing one car at a time. But if you want the CZ from Atlas, that's the only way to do it. Although Lionel's new version of the CZ cars will be 18" vs 21" from Atlas-O, I opted for Lionel's entire set approach due out mid-2013.
