Gosh folks, last I looked this topic is posted in "Hi-Rail, O27 and Traditional 3-Rail O Gauge" forum, not in any of the Scale forums.
I still think its a darn good looking set. Of course, I am more into operating fun than minute details of any of these trains. I am one of the outliers who isn't into all the minutiae some are. Perhaps that discussion would be better left to the Scale Forums.
As long as the set is being enjoyed by the originator of this topic, then so be it. I for one would love to have a set like this in the 15" Class of passenger cars that would run on my layout.
To each their own.
