Yes.  Don't forget that N&W business cars were rebuilds of 
heavyweight cars to begin with.  The basic structure of lightweights 
(truss carbody) vs. heavies (huge center beam or sill with the car 
body built up from it accounts for a lot of the weight 
difference.  Heavyweight Pullman cars at about 75 tons were almost in 
a league with business cars for weight.
