I'm surprised (and relieved) that the 10001 isn't on the list as it's currently in Bear on the dead line.
Some commentary:
Noticed the F40s for sale are the final 1987 series. Of the entire F40 fleet (1976-87), why were the lower 200 series favored for NPCU conversion?
The Horizons I could see several buyers. NCDOT might want to add to their 1965 coach fleet (KCS/Pullman and UP/St. Louis coaches), given these are the oldest coaches in Amtrak service (either Federal routes or state funded corridors). Caltrans could add them to their Comarrow fleet, which already has Horizon dinettes teamed up with the Comarrow coaches, with the climate more favorable than what the Horizons experienced in Chicago.
The 1500 series MHC boxcars are 1988 Thrall build, not 1990. Morristown & Erie bought quite a few 1400s and many Heritage baggage cars (including the Adirondack, Vermonter and Ethan Allen cars, being St. Louis built U.S. Army conversions).
