I know it's kind of an odd request, but could someone dirty up the NS heritage packs? In real life, I don't believe the heritage units have had a bright gloss since they came off the assembly line. Just like any other Gevo or SD70ACe, they are used in mainline service, so they will be dirty. Most of the dark HUs could probably get away with a dusting, but the bright ones would probably need a bit more attention.
And even though the Penn Central doesn't show dirt that well, the paint is chipping all around the engine.
