Both Intermountain and Red Caboose offer their 1937 AAR box car in the SP's Overnight scheme. As I understand it, this scheme was ONLY applied to cars built with Improved Dreadnaught Ends (but were 10 ft high inside), but I want to make sure before I criticize this version. (If I remember Tony's article in RMC, these were the SP's first box cars with this end.)
