Cars of fallen flags SSW and SP

[eightyeightfan1]

A few years ago I saw a Conrail unit coal train come through Cedar Hill Yard. Some of the hoppers were marked with "NYC", "PRR", "LNE" and even a couple of "PC" and "NH". Very few were marked "CR". Most you can tell were repainted and fresh markings were applied. Some had patches with the markings above. It semed out of place, but someone told me they do this to keep the class of hoppers seperate. Such as an H23 might have been marked PRR, and H30, would be marked NYC, and so and so on.
