I would love to see some affordable scale models ($50-100) of two-, three-, or four-dome steam-era tank cars. I think the Rail King 3-dome car, and maybe some of the other 2-and 3-dome cars from Lionel and K-Line, may actually be at or close to scale size, but I don't have scale drawings to check them against. These were very small cars - there's one in the Pennsylvania Railroad Museum and it's dwarfed by an ordinary 40' boxcar.
I once got my hands on a scale drawing of the old Heinz closed-side pickle vat cars and discovered, to my surprise, that the K-Line car, advertised as traditional size, was actually to scale. The Rail King tanker and some of the others may well be at or near scale, but I'd still like to have a well-detailed scale car without having to find, pay for, and convert a 2-rail brass model.
And many thanks to Erik for posting the photos!
