This sure has stirred up a lot of discussion, mostly negative about the Lionel CZ cars.
I remember what some long time model master told me years ago:
This is a hobby, not reality, and should be enjoyed by what YOU like most about the hobby. That there are several layers to this hobby:rivet counters, semi-scalers, model/toy train operators, collectors, etc. If you really like something prototypically correct or not, it shouldn't matter what others may think about your modeling interests. It only matters to you.
That being said, there will be a number of individuals that will overlook the flaws in the Lionel CZ cars. These will most likely be the toy train operators who are not interested in correctness. But then, most all of Lionel products are really not prototypically correct.
For me, I am not a rivet counter, but want to capture the essence of the model. So I put myself in the semi-scaler level.
I too am disappointed in the final finish of the Lionel CZ cars. It's lack of finish and lack of a skirt has turned me off, especially since I saw a couple of the pre-production models.
But remember, at 18 inches that's only 71 scale feet, not 82 feet as were the actual CZ cars. There is no excuse for the flat painted finish. And perhaps the missing skirts were done so these cars can run on smaller radius track.
To compare most Lionel models to a true scale model, is like comparing tofu to apples. They don't taste the same.
Lionel, in my opinion, for the most part puts out a very good product. I think that they know their target market is to hi-rail modelers; semi-scale, toy operators, collectors, etc and NOT to the "rivet counters".
So the next time someone comes out with a model of, say, the Pioneer Zephyr painted as either a Yankee Flyer or in a green and red Christmas scheme, it may not appeal to me, or to other true CB&Q modelers, but there are others who will jump in a add it to their collection.
