I know the B&O and the Wabash did it. The B&O covered M26 box carsTony Thompson has already responded re: the SP stock cars that were
converted from box cars, as has Staffan Ehnbom re: the GN's rebuilt
cars. In addition, the Santa Fe had several thousand stock cars in
classes Sk-Z, Sk-2, Sk-3, Sk-4, and Sk-5 rebuilt from sectional-
sheathed box and auto cars from the early 1940s to the early 1950s.
And the Union Pacific's S-40-10 and S-40-11 classes were converted in
the 1930s from B-50-11 class box cars and A-50-5 class auto cars;
many of these were later upgraded with roller bearings and such to
operate in the unit train "Daylight Livestock Express" service from
Salt Lake City to Los Angeles. Finally, the Western Pacific rebuilt
some single sheathed box cars into 40' stock cars.
