O is the next scale my FOOT!
You forgot both S scale and the little-known TT scale!
Shame on you, GEC!
Hello mr. Shame! TT= 1:120, which is smaller than HO, do your research. Research before you begin to type something on this forum, please for the benefit of other people who want to know the correct answers to their questions.
S scale IS a major scale, it's not just American Flyer anymore. Check out these HIGHLY detailed models by S Helper Service, some of the best injection molded plastic models I've ever seen.
American Flyer Compatible S scale model trains from the Showcase Line Lots of people do S scale, or this, and a handful of other companies wouldn't have spent millions (NO KIDDING) to tool up and create these S scale trains.
OO scale is 1:76, which I think you might have thought TT was. Anyways, OO is a distinctly british scale, so no worrys there.
Bachmann's On30 offerings are the best route for stuff to match the Dept. 56 buildings in scale. Plus, they're big enough to play with, and sturdy too. Not to mention that they're excellent looking too.
I'd go with E-Z track or equivalent snap-together roadbed track, like Atlas' True Track.
