Recently visited a neat hobby shop up towards the Pocono region and Scranton Pa. the owner has his layout Throughout the shop and had quite a few lines dedicated to 2 Rail- he also had a bench of works in progress that he was converting to 2 Rail. While the train selection was on par with an LHS, the selection of track was more than you see at the biggest hobby shops- 2 or 3 types of atlas, selection of Gargraves that was more than I could count, MTH realtrax & scaletrax, Lionel Fastrack, tubular O and o-27, it was impressive.
Got me thinking of which track I want to use as I expand my layout(13 by 7, about to be 16 by 7). Max radius is O-42, outer loop realtrax inner is Fastrack. Had been thinking of upgrading outer loop to 0-54 for awhile but with such a small width. Sorry for the tangent. But there is 2 Rail scale out there, more of a niche market but MTH and others had taken steps to make their engines and rolling stock useable on 2 Rail
