I have previously commented on how I love to model the early 1980s, when colorful former per-diem boxcars roamed the rail network. The D&H had boxcars painted red, orange, yellow, green, brown, dark maroon/purple, and blue (in MOW service). Pity those modelers who build layouts devoted to the Pennsylvania Railroad, where every train contained strings of dull brown boxcars. Not the D&H!
... or at least not during the time frame I model. As can be seen below in these shots dated August 1977, strings of old D&H 40' boxcars await their fate which I assume is scrapping.
They look like 40' cars, which fell out of favor by that time. Note that a couple have yellow lettering on a reddish-brown carbody, while most have white lettering on a brown carbody.
