While the Coors reefer is a repaint, at least it's a wood-sided reefer, like the originals. Not many of those left. (That Armour reefer is a later steel-sided one, of course.) It's no surprise there are so few of them left, given that wooden cars would have a fairly limited lifespan. An original of these woodside reefers would be about 80 years old now!
Well, at least here's a Coors "billboard" switcher :
(Re: the odd hoppers, Coors operates with a fleet of eleven of these captive covered hoppers to move grain products from the East Silo west to the brewery. These hoppers are custom-equipped with pneumatic gates and electrical hookups tied into timers in the brewing process. This enables the cars to release a precise amount of grain directly into seep tanks at the appropriate time in the brewing process—even if no one’s around!)
