What I mean is N&W, NKP, Wabash, Illinois Central, Chicago Great Western, Rock Island (well, you get the picture) and southern roads: Southern, ACL, Seaboard Airline, Clinchfield, C&O etc.

For the DRGW version, although the particular number Athearn did isn't in the roster, these type of 13 pocket flat cars seem to be popular from 58-63 on the Rio Grande. http://www.drgw.org/data/freight/1960/flat.htm Tony Burzio San Diego, CA
