Chuck, if they will run on 20"R track, and their TMCC predecessors do, it is more than a typo because it appears in multiple places. It does not matter to me because I only have 30" and larger radius track. Perhaps somewhere in the product planning cycle the minimum radius changed and it was missed in the copy editing.
I was just running my TMCC NYC Light Mikado with a long string of freight cars behind it. Will be nice to have a Legacy Light Pacific version even though the NYC never had that engine.
There are very few Legacy and Vision line O gauge engines I would not buy. Maybe Lionel could start with the Legacy B6 Sb in S gauge, then the PRR 6-4-4-6 Torpedo and then a Reading T1. An H1 would also be nice.
