I was at the Edaville RR last summer. They have two passenger cars, ERR 127 and 128 from the High Country RR. Which are supposed to be re-built from cars of the Colorado Central which were built in 1884.
Today there is not much old wood there, but they are much nicer than your typlcal open Excursion Cars. They have clearstory windows above the roof line.
There was an article on the High Country RR in the NMRA Bulletin for August 1975. They had the two foot Shay which was former good roads Con Co at Leachville,AK; Colbert Lime Rock,Cherokee, AL
and Birmingham Slag, Birmingham, AL. Don't know where the High Country got her from. The rest of the engines were German 60cm. The operation is mentioned several times in the Iron Horse News of the time. Hope that helps. TM
