Paul,

Atlas O is US O scale, i.e. 1/4" = 1' or 48:1, but 1 1/4" gage.
(Sometimes referred to as Ow5). The trucks are clunky, but easily
replaced.

If you're interested in true 56.5" gage in Oscale, by all means join
the Yahoo Proto48 group.

Atlas is producing more and more "O" freight cars, like USRA boxes &
gons, etc. What scale are these cars being built to?

1-1/4" scale bodies w/7mm scale-gauged trucks?
2-7mm bodies & 7mm scale-gauged trucks?

Thought I'd get some info before I make the 50 mile trip to

my "local"

hobby shop.

I will be laying my own "O" track, at 1/4" scale = 4'- 8 1/2" gauge.
