Are the designations for paint schemes such as YN, YN2, YN3, Bright Future, Dark Future, etc all railfan created, or are some of them official or unofficial CSX designations?
I *think* the designations are CSX-created, but if I'm wrong, please correct me.
But, I believe YN, or "Stealth" is CSX's first corporate scheme
C40-8 #7587
YN2 or "Bright Future"
SD-50 #8629
YN3 or "Dark Future"
SD60I #8749
Hope that helps!
