2014-Year of The Reefer!
With all the Big Boys, SP Cab Fwd and FEF(MTH), I'm surprised there are any left in circulation!
I own a LOT PFE Reefers (Lionel mostly, 15 MTH) and they're some of my favorite rolling stock. Then again, I model UP Steam Era so that makes since.
I don't remember the author, but there is a book titled, Pacific Fruit Express, with a Big Boy and reefers on the cover. It's excellent, sure it is on Amazon cheap.
Thanks for the pictures!
