Great find Kurt! Looks like maybe an old caboose. It's marked as yard service so maybe it's later years could have been a mobile office or maybe a shoving platform back before that was the trend.
Yeah, hopefully they can restore it like the GN and Milw passenger cars there. I wanna say this was an older transfer caboose, probably from the Twin-Cities area?
I don't know very much about the GN, but I'll agree that this definitely looks like a transfer caboose. Nice find.
Nice! That car certainly is a caboose, specifically X702, one of the transfer type cars built in the 1920s. Don't know if this car ever was built with a cupola or not, but judging by the window spacing, it appears that it once was but was later modified.
I started wondering if such work did occur, when. Then thought of World War II, when other RRs converted box cars, and did other work to fill needs for cabooses.
