StevefromPA - I have no issues running any of my intermodals on 042 curves. That includes MTH Premier and RailKing, K-Line, and Lionel traditional and scale cars. I was looking at the scale auto carriers but those look like they need 052 minimum. Aren't the Menards cars semi-scale similar in size to RailKing? Never seen those at my local Menards. BTW - lot of work putting those photos together - nice job. Missed your earlier post on the mis-marking on the K-Line cars and confirmed by Jeff78rr.
One of these days I'll have to understand the differences between Husky Stacks / Maxi Stacks / Thrall / Gunderson / DTTX / TTX and so forth.
Of course as is common on this forum the information exists on other topic pages - just saw the extensive write up on these under the O Scale Freight Car Guide: Intermodal Cars topic linked earlier on this thread. Too bad there are missing photos.
