Dave, my new layout can handle scale stuff. But I also ordered MTH's RailKing version of this offering, because the ever-so-slightly smaller size just "looks better" in some vignettes on the layout. I'm finding some of the modern RailKing stuff is not dramatically different in size from the true-scale Premier line. For example, MTH has been offering the FM diesel locos in RailKing, and they're so close to scale it's not even worth mentioning they're not.
