It would look compact, this was small by US standards. Although destined for use in Europe from D-Day it was built to British loading gauge and naturally had a wide route availability. Their history is interesting.
You would hope so, the USATC bogie tank cars which saw use in the UK and the USATC four wheel wagons, vans and brake vans.
What I find amusing was the mystique surrounding the real S160s back in the 1980s with, stories of secrecy, strategic reserves, etc., whereas now you can pop in your local model shop and buy one in 00!
I've got a few USATC wagons in the H0 collection, they seem
really small! About 25 years ago I used to have more (Sachsenmodelle and possibly Kleinbahn; the current ones are Roco). At one time I thought about something based on a mythical island in the Channel with leftover USATC plus other things, though there was some USATC stuff on at least one French secondaire IIRC. I suppose a 00 continental line could be fun...quite a few French-prototype kits for 60cm stuff were 009 rather than H0e as it makes the track gauge a bit less incorrect so perhaps an interchange in Northern France with a sugar beet line using Bachmann ex-WD stuff would work.
All getting into the realms of fantasy a bit, so best I go to sleep
