with the same head end power, Hafner also offered a Century of Progress freight set...
hard for me to say as a freight car fan, but i can see why the passenger set was far more popular. while the passenger set had some embossed detail around the windows and doorways, the freight cars were punched flat without much lithograph detail...
the boxcar (no doors) was essentially the passenger set express - baggage - mail car without the end doors and a less detailed roof.
add a cupola with side windows rather than a doorway and the rear end light from an observation car to make a caboose,
and the sand car already existed as an all red version of the early NYC Sand & Gravel car.
cost saving ideas like this, however, likely helped Hafner survive the depression years.
the last oddball from this era...
not considered an error, the plain-Jane version of the baggage car.
simple, but IMO really says it all ... 
cheers...gary
