I model the ATSF in the 1948-1951 time frame and have 3 semi-accurate (compressed to fit on my layout) consists of the famous Chicago to Los Angeles streamlined trains of the era: The Chief, The Super Chief, and El Capitan. I'd like to add The Grand Canyon to that list. The consist for the train was always a mix of whatever extra cars were available and over flow head end cars from #7/8, The Fast Mail Express. Passenger cars would be a mix of heavyweight and lightweight equipment, which will be a perfect use for my extra random ATSF passenger equipment.
At this point in time the big 3 streamlined trains, The Chief, The Super Chief, and El Capitan, ran with round end observation cars at the rear of the train with the train's logo/name displayed on a drumhead mounted to the rear door. All the information I have in my ATSF books and searching on the internet never shows The Grand Canyon in this time frame operating with an observation car. The last car was usually a heavyweight or lightweight sleeper. There is a drumhead for The Grand Canyon however. My question is was this usually placed on the last car of the train? I have yet to find a photo of the last car of train #23/24 sporting a drumhead in the 1948-1951 timeframe. I'd like to know if it's more prototypical to leave the last car of the train blank or if I should install a Grand Canyon drumhead on the last sleeper? Any insight would be great.
