Could someone describe UP's box car fleet circa 1946?
I know they had some double sheathed box cars like the ones
Westerfield offers and "standard" 1937 10' IH box cars like Red
The ORERs show they have a lot of cars with in IH (inner height) of
about 9 ft. Were these double sheathed or steel cars? What kinds of
ends and roofs did they have?
There's a photo a a UP double sheathed in the 1931 CBC reprint which
shows a herald like the ones on PFE reefers. How long did that last?
What % of box cars were marked for subsidiaries like OSL?
