Peter, looking at your blowup, you are probably correct - RATS! The Lionel Superliners are way overdue. The old 18" ones were not bad, but the current scale cars will be much better. I had a set of K Line Superliners but sold them several years ago because K Line never did the Lounge car with its unique window pattern, which to me is the defining car of the series.
But a couple of years ago, I was able to put together a full set of the K Line El Capitan cars, still minus the lounge. But, I figured the complete set, even without the lounge, is better than not having the set at all!
