Well we all knew that it wasn't going to be a spot on model of the 630, it does sound good and it is a fine looking model. I'm just wondering though if it isn't a closer model to the Southern 542 over at Spencer, NC? (sorry I do not know the southern class offhand)
I'm thinking Lionel could have made this one in lieu of the 630 and gotten pretty close to the prototype. But as long as the owners enjoy it that's all that matters.
