While I could list endless "desires" of real life paint schemes, I have another intriguing idea. Why not paint some of your current models (-2's, -7's, -8's, etc etc) into fallen flag schemes, must like the heritage units of NS. Multiple old paint schemes could be used, depending on when the railroad may have gone back to their most inspiration look (as applied to the heritage units). It would be fun to recreate a modern day Erie or NKP. Many of these roads have units up through the -2 and -7 models, and with the heritage 70ACe's and ES44's already complete, a couple filler units such as 60's or -8's or -9's would fill the time gap, along with an SW1500 or F7 for added fun. There are so many possibilities for new payware paint schemes on current models, that you could create until you're heart's content, and we'd keep buying! Thanks!
Edit: to expand on my above idea, I offer these suggestions: (some may be prototypical models, and others may be “close enough” models to represent the real deal
