Fast forward four years to 12/1985, and here is the same car #30123. While everything is faded, it looks like at least portions of the yellow paint have been redone. Also, some white lettering in the lower right corner appears to have been patch-painted on.
Oddly, though, I haven't seen any pictures of boxcars painted in the blue color scheme and used for MOW services. Either they existed but alluded the cameras, or more likely the D&H just didn't bother to repaint them. Anything stored in the boxcar could also be stored in the baggage car, which had nearly double the capacity of an old 40' boxcar. And, the baggage car's side doors still allowed large things in and out. So who knows? I will still be on the lookout though.
