FWIW, I keep a pretty good set of books and track (not a pun) all my sales. Nearly half are for P:48. I think the largest flaw in all the wisdom being shared here...just because you don't get involved doesn't mean others are not. P:48 is growing far faster than most of you seem to realize.
There is a very large percentage of modelers moving from smaller scales to O Scale & P:48.
Like it, love it, hate it, ambivalent? So is the large bird with his head stuck in the sand.
