The appliance that would force the development was the Evans Auto

automobiles when loaded and to stow the loader when empty or when the
car was used to handle other freight. Widespread use of these taller
automobile cars would not occur until 1934 with the introduction of
the PRR Class X31 automobile boxcars. The older automobile boxcars
were still around, but they would be bumped from finished automobile
service, with some rebuilt into general service boxcars such as the
PRR Class X28A or N&W Class BPA.
All true as far as it goes, but Ben's perspective here is that of a
historian and modeler whose primary interest is eastern RRs. Ten foot
high automobile cars, many of the 50'6" in length, were common in the
1920s on many western railroads (ATSF, SP, UP, GN, NP, WP) and some
east-of-the-Rockies lines like the MoPac and CB&Q, though rare on RRs
east of the Mississippi owing to their limited clearances. Such cars
were easily converted for use with Evans racks, and many were so
converted. By contrast, eastern RRs had to build new, taller cars like
the PRR X31s to accommodate Evans racks.
