Scott,
Thanks! I’d be in for the Santa Fe “Super Fleet” freight version. That’s the revived warbonnet scheme with the large red Santa Fe lettering (road numbers 90-98) and represents the engines’ appearance from 1989 until retirement. That would compliment your upcoming SD40-2s nicely. I think I’d also go for one in the Santa Fe “Kodachrome” scheme of the late 1980s.
