While wading through the O scale caboose auction category, inspired by the thread running on here about ATSF cabooses,
I discovered a kit offered for an early U.P. "narrow gauge" caboose. The prototype photo in the auction shows this as one
big caboose, for narrow gauge, although there was U.P. narrow gauge on lines they absorbed. It also is a multi-windowed
caboose that I'd first think was a drover's caboose, but, to me, it looks like it could have run on U.P. standard gauge, and,
if on narrow gauge, retrucked. Third Rail offered another model U.P. caboose, in two colors, with and without side door. Like ATSF (with its super common "Athearn HO" caboose in model trains), but with other versions less known, I wonder if that caboose was operated on U.P. std. ga. and what other less common cabooses showed up on the U.P.?
