Jack, regarding that 1967 Directors' Special, it is pictured in the same book on Page 34. Of the 6 car consist behind the heater car, a diner and one GN business car were still in orange and green. The rest of the train was a full-dome lounge car and three more GN business cars. (The last car would be A28, President John Budd's car.) There wasn't a baggage car in the train. I've never seen a baggage car in any other GN director special consist photos, either. FYI.
OK, thanks. I was just going by memory, and since it was 48 years ago, I didn't remember for sure which car/cars were NOT painted in BSB. I remember taking a few color slides as the train departed, and couldn't believe the GN painted cars in the train.
